Why Springtime Duct Cleaning Matters for Allergy Season in Minnesota

5/13/2026

0 Comments

 
Spring duct cleaning helps reduce allergens, improve indoor air quality, and freshen your home after winter. Learn why Minnesota homeowners should schedule duct cleaning this spring.

As the snow melts and windows begin to open across Minnesota, many homeowners look forward to warmer weather, blooming flowers, and fresh spring air. Unfortunately, spring also brings something less enjoyable — allergy season.
If your family struggles with sneezing, itchy eyes, congestion, or poor indoor air quality during spring, your home’s air ducts could be part of the problem. After a long Minnesota winter with the furnace running constantly, dust, pet dander, pollen, and debris can build up inside your ductwork and continue circulating throughout your home.
Professional spring duct cleaning can help improve indoor air quality, reduce allergens, and create a cleaner, healthier home environment.

Why Allergies Get Worse in SpringSpring allergies are commonly triggered by:
  • Tree pollen
  • Grass pollen
  • Dust mites
  • Pet dander
  • Mold spores
Even if you keep your home clean, these allergens often collect inside HVAC ductwork over time. Every time your heating or cooling system runs, those particles can be pushed back into the air your family breathes.
In many homes, indoor air can actually contain more pollutants than outdoor air — especially after a long heating season.

How Dirty Air Ducts Affect Your HomeYour duct system acts like the lungs of your home. Over the years, contaminants can build up inside the ducts, including:
  • Dust and dirt
  • Pet hair and dander
  • Pollen
  • Mold spores
  • Construction debris
  • Bacteria and odors
When airflow moves through dirty ducts, these particles circulate through your vents and living spaces.
Common signs you may need duct cleaning include:
  • Excess dust around vents
  • Increased allergy symptoms indoors
  • Musty odors when the HVAC system runs
  • Uneven airflow
  • Dust buildup shortly after cleaning
  • Recent remodeling or construction

Benefits of Springtime Duct Cleaning1. Reduce Allergens in Your HomeProfessional duct cleaning removes many of the particles that contribute to allergy symptoms. This can help create a cleaner breathing environment for your family.
2. Improve Indoor Air QualityCleaner ducts mean cleaner circulating air. Many homeowners notice fresher-smelling air and less dust throughout the home after service.
3. Help Your HVAC System Run More EfficientlyHeavy dust buildup can restrict airflow and make your heating and cooling equipment work harder. Cleaner airflow can help your HVAC system operate more efficiently.
4. Remove Winter Dust BuildupMinnesota winters often mean months of closed windows, dry air, and constant furnace operation. Spring is the perfect time to clear out accumulated debris before air conditioning season begins.
5. Create a Cleaner HomeLess dust circulating through the system can mean less dust settling on furniture, floors, and surfaces.

Why Spring Is the Best Time for Duct CleaningSpring is ideal because homeowners are transitioning from heating season into cooling season. Cleaning your ducts before summer means your air conditioner starts the season with cleaner airflow throughout the home.
It’s also a great time to schedule:
  • Furnace maintenance
  • Air conditioner tune-ups
  • Filter replacement
  • Indoor air quality inspections

How Often Should Air Ducts Be Cleaned?Most homes benefit from duct cleaning every 3–5 years, but you may need more frequent cleaning if you:
  • Have pets
  • Have family members with allergies or asthma
  • Recently completed remodeling projects
  • Notice excessive dust
  • Smoke indoors
  • Have older duct systems

Choosing the Right Duct Cleaning CompanyNot all duct cleaning services are the same. Look for a company that:
  • Uses professional vacuum and agitation equipment
  • Cleans the full HVAC system
  • Has strong local reviews
  • Explains the process clearly
  • Is licensed and insured
  • Offers honest recommendations without pressure
A quality duct cleaning should focus on improving airflow and indoor air quality — not high-pressure upselling.

Breathe Easier This SpringIf your allergies seem worse indoors or your home feels dusty after winter, spring duct cleaning can make a noticeable difference. Cleaner ducts help support cleaner air, better comfort, and a healthier home environment for your family.
Spring is the perfect time to freshen up your HVAC system and prepare your home for warmer weather ahead.

Spring Allergies in Minnesota: Why Your Home Could Be Making Them WorseAs the snow melts and the trees begin to bloom across Minnesota, many homeowners are ready to open the windows and enjoy spring. Unfortunately, spring also brings sneezing, itchy eyes, congestion, headaches, and poor indoor air quality.
If your allergies seem worse inside your home than outside, your HVAC system may be part of the problem — or part of the solution.
Why Spring Allergies Hit So HardSpring allergens are everywhere in Minnesota this time of year:
  • Tree pollen
  • Mold spores from melting snow and damp areas
  • Dust and pet dander trapped indoors all winter
  • Dirty furnace filters and ductwork
  • Poor ventilation in tightly sealed homes
Once these allergens enter your home, they circulate through your heating and cooling system over and over again.
Signs Your Home’s Air Quality Needs AttentionYou may benefit from HVAC maintenance or indoor air quality improvements if you notice:
  • Increased sneezing or coughing indoors
  • Dust buildup around vents
  • Musty odors when the furnace or AC runs
  • Frequent headaches or sinus irritation
  • Uneven airflow throughout the home
  • Allergy symptoms that worsen at night
How Your HVAC System Can Help Reduce AllergiesA properly maintained HVAC system can dramatically improve your indoor air quality during allergy season.
1. Replace Your Air FilterYour furnace filter is your first defense against pollen, dust, and airborne irritants.
During spring:
  • Check filters monthly
  • Replace dirty filters regularly
  • Upgrade to a higher-efficiency filter if your system allows it
A clogged filter restricts airflow and allows allergens to circulate through your home.
2. Schedule Spring HVAC MaintenanceSpring is the perfect time for an AC tune-up and system inspection.
Professional maintenance helps:
  • Improve airflow
  • Remove dust buildup
  • Ensure proper humidity control
  • Increase system efficiency
  • Catch small issues before summer heat arrives
Bonus: A clean system often means lower energy bills too.
3. Consider Whole-Home Air PurificationModern indoor air quality solutions can significantly reduce allergens inside your home.
Popular options include:
  • Whole-home air purifiers
  • UV light systems
  • HEPA filtration
  • Humidifiers and dehumidifiers
  • Duct cleaning services
These systems work with your existing HVAC equipment to help your family breathe cleaner air year-round.
4. Don’t Ignore Your DuctworkDust, pet hair, pollen, and debris can build up inside air ducts over time.
If your home has:
  • Excessive dust
  • Recent remodeling
  • Pets
  • Older ductwork
  • Allergy sufferers
…it may be time for a professional duct inspection or cleaning.
Simple Ways to Reduce Allergens at HomeHere are a few easy spring allergy tips homeowners can start today:
  • Keep windows closed on high-pollen days
  • Vacuum frequently with a HEPA vacuum
  • Remove shoes at the door
  • Wash bedding weekly
  • Keep humidity levels balanced
  • Change HVAC filters regularly
Breathe Easier This SpringSpring should be about enjoying warmer weather — not battling allergy symptoms inside your own home.
At Swenson Heating & Air Conditioning, we help Minnesota homeowners improve comfort, indoor air quality, and HVAC performance all season long.

  • Spring AC maintenance
  • Air filtration upgrades
  • Indoor air quality solutions

When Is the Right Time to Replace Your Air Conditioner?

4/23/2026

0 Comments

 

Most homeowners don’t think about replacing their AC until it stops working—but the best time to replace your system is before it fails. Planning ahead can save you money, stress, and discomfort during the hottest days of summer.
Here’s how to know when it’s time.

1. Your AC Is 10–15+ Years OldThe average lifespan of an air conditioner is about 10–15 years.
If your system is:
  • Over 10 years old → start planning
  • 12–15+ years old → seriously consider replacement
Newer systems are far more energy-efficient, which can significantly lower your cooling costs.

2. Frequent Repairs Are Adding UpIf you’re calling for repairs every summer, those costs add up fast.
A good rule:
  • If a repair costs 30–50% of a new system, replacement is usually the smarter investment

3. Your Energy Bills Keep RisingOlder systems lose efficiency over time. If your cooling bills are climbing but usage hasn’t changed, your AC may be working harder than it should.
New high-efficiency systems can reduce energy usage by 20–40%.

4. Your Home Isn’t Staying ComfortableHot spots, weak airflow, or humidity issues are signs your system isn’t keeping up.
This is especially common in Minnesota homes where systems are pushed hard during seasonal swings.

5. Your System Uses R-22 RefrigerantIf your AC uses R-22 (Freon), replacement is often the best move.
  • R-22 is phased out
  • Repairs are expensive
  • Refrigerant is hard to find

6. It Breaks Down at the Worst TimeIf your AC quits during a heatwave, you’re stuck:
  • Paying emergency rates
  • Waiting for service
  • Possibly rushing into a decision
Replacing in spring or early summer avoids this.

7. You Want Better Efficiency & ComfortNew systems offer:
  • Better temperature control
  • Improved humidity control
  • Quieter operation
  • Smart thermostat compatibility

Best Time of Year to Replace Your ACThe smartest time to replace your system is:
🌱 Spring (BEST)
  • Beat the summer rush
  • Better scheduling availability
  • Ensure you're ready for heat
🍂 Fall (Also Good)
  • Lower demand
  • More flexible install times
🔥 Peak Summer (Worst Time)
  • Emergency replacements
  • Limited availability
  • Higher stress

Repair vs Replace: Quick Rule of Thumb
  • Under 10 years old? → Usually repair
  • Over 10–12 years + issues? → Consider replacement
  • Major repair needed? → Replacement often makes more sense

What to Look for in an HVAC Company (Before You Hire One)Choosing the right HVAC company can mean the difference between a quick fix and an expensive headache. Whether you need air conditioning maintenance, furnace repair, or a full system replacement, it’s important to know what separates a reliable contractor from the rest.
Here’s what homeowners in Minnesota should look for when hiring an HVAC company.

1. Proper Licensing & Insurance
A reputable HVAC company should be fully licensed and insured. This protects you as a homeowner and ensures the company meets state and local requirements.
What to ask:
  • Are you licensed in Minnesota?
  • Do you carry liability and workers’ comp insurance?

2. Strong Local Reputation
Look for a company with consistent, positive reviews and a strong presence in your community.
Check:
  • Google reviews
  • Facebook recommendations
  • Word-of-mouth referrals
A company that’s been serving your area for years is more likely to stand behind their work.

Experience matters—especially in Minnesota, where HVAC systems deal with extreme temperature swings.
Companies with decades of experience have:
  • Seen every type of system issue

  • Earned long-term customer trust

4. Clear, Honest Pricing
Avoid companies that give vague estimates or pressure you into upgrades.
A trustworthy HVAC company will:
  • Provide upfront pricing
  • Explain your options clearly
  • Never push unnecessary repairs

5. Maintenance & Service Options
A good company doesn’t just fix problems—they help prevent them.
Look for:
  • Seasonal maintenance plans
  • Spring AC tune-ups
  • Fall furnace inspections
Regular maintenance saves money and extends system life.

6. Fast, Reliable ServiceWhen your heat goes out in a Minnesota winter (or AC in the summer), response time matters.
Ask:
  • Do you offer emergency service?
  • How quickly can you schedule service calls?

7. Professionalism & Communication
From the first call to the final invoice, professionalism should be consistent.
Signs of a great company:
  • Friendly, knowledgeable staff
  • Clear communication
  • Clean, respectful technicians

8. Warranties & Guarantees
Reputable HVAC companies stand behind their work.
Look for:
  • Labor warranties
  • Manufacturer warranties
  • Satisfaction guarantees

9. Local Knowledge Matters
HVAC needs in Minnesota are unique. A local company understands:
  • Cold-weather furnace demands
  • Humidity control in summer
  • Energy efficiency for extreme climates

As a family-owned company since 1969, Swenson Heating & Air Conditioning has built a reputation for honest service, reliable work, and long-term customer relationships.

While many of us are anxious to put this cold, snowy winter behind us there are some important things to keep in mind with the warming temperatures and the volume of melting snow we're likely to see.
 
To help keep the water out of your home here are some things you can do:
 
Clear the snow from your roof - Whether it's with a snow rake or a shovel, pay extra attention to the bottom side so when the snow does melt it can get to your gutters or has somewhere to go besides in your home.

Shovel around your house - Ideally snow should be cleared 3-5 feet from your foundation, the further away it is the less you're going to have running in to your home.  Seepage is typically not covered so it's important to figure out how water drains away from your home. This will also provide relief to your sump pump.

Check the discharge line for your sump pump - It should be cleaned, not frozen or covered by snow to prevent water backing up in to your basement.  Also test it to make sure it is properly working by using a 5 gallon bucket and placing water into the sump pump basin. We are always available to review your water/sewer back up coverage but please note there is a 10 day waiting period to increase coverage.

Flood policies - We have had a number of inquiries about flood policies and in general they do not cover seepage through a foundation or floor like what may happen with melting snow.  However, if an overflow covers 2 acres or more that is considered a flood and rising ground water seeping into a basement would be covered under a flood policy. There is a 30 day waiting period for flood policies to kick in. We're happy to discuss this more in depth with you if you have additional questions.

Ice Dams - Similar to flood policies we've had many questions on coverage for ice dams.  In general they would be covered assuming they're causing damage to the interior of your home but the removal would only be covered in the area where damage has occurred. (If it is not causing damage to your home removal would not be covered.)  If you find yourself in this situation, please call us to discuss if a filing a claim is your best long-term interest.  In addition, there are a number of companies advertising ice dam removal service and as with any contractor it's important to find one with an acceptable reputation and the proper insurance coverage (i.e. General Liability and Workers Compensation.)

EXTREME HEAT… A prevention guide to your personal health and safety.

7/18/2013

3 Comments

 

Temperatures rise in the Minneapolis Metro area!

Elderly people (65 years and older), infants and children and people with chronic medical conditions are more prone to heat stress.

Air-conditioning is the number one protective factor against heat-related illness and death. During conditions of extreme heat, spend time in locations with air-conditioning such as shopping malls, public libraries, or public health sponsored heat-relief shelters in your area.

Get informed. Listen to local news and weather channels or contact your local public health department during extreme heat conditions for health and safety updates
Drink cool, nonalcoholic beverages and increase your fluid intake, regardless of your activity level.

Heat-related deaths and illness are preventable yet annually many people succumb to extreme heat. Historically, from 1979-2003, excessive heat exposure caused 8,015 deaths in the United States. During this period, more people in this country died from extreme heat than from hurricanes, lightning, tornadoes, floods, and earthquakes combined. In 2001, 300 deaths were caused by excessive heat exposure.

People suffer heat-related illness when their bodies are unable to compensate and properly cool themselves. The body normally cools itself by sweating. But under some conditions, sweating just isn’t enough. In such cases, a person’s body temperature rises rapidly. Very high body temperatures may damage the brain or other vital organs.

Several factors affect the body’s ability to cool itself during extremely hot weather. When the humidity is high, sweat will not evaporate as quickly, preventing the body from releasing heat quickly. Other conditions related to risk include age, obesity, fever, dehydration, heart disease, mental illness, poor circulation, sunburn, and prescription drug and alcohol use.

Because heat-related deaths are preventable, people need to be aware of who is at greatest risk and what actions can be taken to prevent a heat-related illness or death. The elderly, the very young, and people with mental illness and chronic diseases are at highest risk. However, even young and healthy individuals can succumb to heat if they participate in strenuous physical activities during hot weather. Air-conditioning is the number one protective factor against heat-related illness and death. If a home is not air-conditioned, people can reduce their risk for heat-related illness by spending time in public facilities that are air-conditioned.

Summertime activity, whether on the playing field or the construction site, must be balanced with measures that aid the body’s cooling mechanisms and prevent heat-related illness. This pamphlet tells how you can prevent, recognize, and cope with heat-related health problems.

What Is Extreme Heat?
Conditions of extreme heat are defined as summertime temperatures that are substantially hotter and/or more humid than average for location at that time of year. Humid or muggy conditions, which add to the discomfort of high temperatures, occur when a “dome” of high atmospheric pressure traps hazy, damp air near the ground. Extremely dry and hot conditions can provoke dust storms and low visibility. Droughts occur when a long period passes without substantial rainfall. A heat wave combined with a drought is a very dangerous situation.

During Hot Weather
To protect your health when temperatures are extremely high, remember to keep cool and use common sense. The following tips are important:

Drink Plenty of Fluids
During hot weather you will need to increase your fluid intake, regardless of your activity level. Don’t wait until you’re thirsty to drink. During heavy exercise in a hot environment, drink two to four glasses (16-32 ounces) of cool fluids each hour.
Warning: If your doctor generally limits the amount of fluid you drink or has you on water pills, ask how much you should drink while the weather is hot.

Don’t drink liquids that contain alcohol, or large amounts of sugar—these actually cause you to lose more body fluid. Also avoid very cold drinks, because they can cause stomach cramps.
​
Replace Salt and Minerals
Heavy sweating removes salt and minerals from the body. These are necessary for your body and must be replaced. If you must exercise, drink two to four glasses of cool, non-alcoholic fluids each hour. A sports beverage can replace the salt and minerals you lose in sweat. However, if you are on a low-salt diet, talk with your doctor before drinking a sports beverage or taking salt tablets.

Wear Appropriate Clothing and Sunscreen
Wear as little clothing as possible when you are at home. Choose lightweight, light-colored, loose-fitting clothing. Sunburn affects your body’s ability to cool itself and causes a loss of body fluids. It also causes pain and damages the skin. If you must go outdoors, protect yourself from the sun by wearing a wide-brimmed hat (also keeps you cooler) along with sunglasses, and by putting on sunscreen of SPF 15 or higher (the most effective products say “broad spectrum” or “UVA/UVB protection” on their labels) 30 minutes prior to going out. Continue to reapply it according to the package directions.
Schedule Outdoor Activities Carefully

If you must be outdoors, try to limit your outdoor activity to morning and evening hours. Try to rest often in shady areas so that your body’s thermostat will have a chance to recover.

Pace Yourself
If you are not accustomed to working or exercising in a hot environment, start slowly and pick up the pace gradually. If exertion in the heat makes your heart pound and leaves you gasping for breath, STOP all activity. Get into a cool area or at least into the shade, and rest, especially if you become lightheaded, confused, weak, or faint.

Stay Cool Indoors
Stay indoors and, if at all possible, stay in an air-conditioned place. If your home does not have air conditioning, go to the shopping mall or public library—even a few hours spent in air conditioning can help your body stay cooler when you go back into the heat. Call your local health department to see if there are any heat-relief shelters in your area. Electric fans may provide comfort, but when the temperature is in the high 90s, fans will not prevent heat-related illness. Taking a cool shower or bath or moving to an air-conditioned place is a much better way to cool off. Use your stove and oven less to maintain a cooler temperature in your home.

Use a Buddy System
When working in the heat, monitor the condition of your co-workers and have someone do the same for you. Heat-induced illness can cause a person to become confused or lose consciousness. If you are 65 years of age or older, have a friend or relative call to check on you twice a day during a heat wave. If you know someone in this age group, check on them at least twice a day.

Monitor Those at High Risk
Although anyone at any time can suffer from heat-related illness, some people are at greater risk than others.

Infants and young children are sensitive to the effects of high temperatures and rely on others to regulate their environments and provide adequate liquids.

People 65 years of age or older may not compensate for heat stress efficiently and are less likely to sense and respond to change in temperature.

People who are overweight may be prone to heat sickness because of their tendency to retain more body heat.

People who overexert during work or exercise may become dehydrated and susceptible to heat sickness.

People who are physically ill, especially with heart disease or high blood pressure, or who take certain medications, such as for depression, insomnia, or poor circulation, may be affected by extreme heat.

Visit adults at risk at least twice a day and closely watch them for signs of heat exhaustion or heat stroke. Infants and young children, of course, need much more frequent watching.

Adjust to the Environment
Be aware that any sudden change in temperature, such as an early summer heat wave, will be stressful to your body. You will have a greater tolerance for heat if you limit your physical activity until you become accustomed to the heat. If you travel to a hotter climate, allow several days to become acclimated before attempting any vigorous exercise, and work up to it gradually.

Do Not Leave Children in Cars
Even in cool temperatures, cars can heat up to dangerous temperatures very quickly. Even with the windows cracked open, interior temperatures can rise almost 20 degrees Fahrenheit within the first 10 minutes. Anyone left inside is at risk for serious heat-related illnesses or even death. Children who are left unattended in parked cars are at greatest risk for heat stroke, and possibly death. When traveling with children, remember to do the following:

Never leave infants, children or pets in a parked car, even if the windows are cracked open.

To remind yourself that a child is in the car, keep a stuffed animal in the car seat. When the child is buckled in, place the stuffed animal in the front with the driver.

When leaving your car, check to be sure everyone is out of the car. Do not overlook any children who have fallen asleep in the car.

Use Common Sense
Remember to keep cool and use common sense:
Avoid hot foods and heavy meals—they add heat to your body.

Drink plenty of fluids and replace salts and minerals in your body. Do not take salt tablets unless under medical supervision.

Dress infants and children in cool, loose clothing and shade their heads and faces with hats or an umbrella.

Limit sun exposure during mid-day hours and in places of potential severe exposure such as beaches.

Do not leave infants, children, or pets in a parked car.

Provide plenty of fresh water for your pets, and leave the water in a shady area.

Hot Weather Health Emergencies
Even short periods of high temperatures can cause serious health problems. During hot weather health emergencies, keep informed by listening to local weather and news channels or contact local health departments for health and safety updates. Doing too much on a hot day, spending too much time in the sun or staying too long in an overheated place can cause heat-related illnesses. Know the symptoms of heat disorders and overexposure to the sun, and be ready to give first aid treatment.

Heat Stroke
Heat stroke occurs when the body is unable to regulate its temperature. The body’s temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. Body temperature may rise to 106°F or higher within 10 to 15 minutes. Heat stroke can cause death or permanent disability if emergency treatment is not provided.

Recognizing Heat Stroke
Warning signs of heat stroke vary but may include the following:
An extremely high body temperature (above 103°F, orally)
Red, hot, and dry skin (no sweating)
Rapid, strong pulse
Throbbing headache
Dizziness
Nausea
Confusion
Unconsciousness

What to Do
If you see any of these signs, you may be dealing with a life-threatening emergency. Have someone call for immediate medical assistance while you begin cooling the victim. Do the following:
Get the victim to a shady area.
Cool the victim rapidly using whatever methods you can. For example, immerse the victim in a tub of cool water; place the person in a cool shower; spray the victim with cool water from a garden hose; sponge the person with cool water; or if the humidity is low, wrap the victim in a cool, wet sheet and fan him or her vigorously.
Monitor body temperature, and continue cooling efforts until the body temperature drops to 101-102°F.
If emergency medical personnel are delayed, call the hospital emergency room for further instructions.
Do not give the victim fluids to drink.
Get medical assistance as soon as possible.
Sometimes a victim’s muscles will begin to twitch uncontrollably as a result of heat stroke. If this happens, keep the victim from injuring himself, but do not place any object in the mouth and do not give fluids. If there is vomiting, make sure the airway remains open by turning the victim on his or her side.

Heat Exhaustion
Heat exhaustion is a milder form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement of fluids. It is the body’s response to an excessive loss of the water and salt contained in sweat. Those most prone to heat exhaustion are elderly people, people with high blood pressure, and people working or exercising in a hot environment.

Recognizing Heat Exhaustion
Warning signs of heat exhaustion include the following:
Heavy sweating
Paleness
Muscle cramps
Tiredness
Weakness
Dizziness
Headache
Nausea or vomiting
Fainting

The skin may be cool and moist. The victim’s pulse rate will be fast and weak, and breathing will be fast and shallow. If heat exhaustion is untreated, it may progress to heat stroke. Seek medical attention immediately if any of the following occurs:
Symptoms are severe
The victim has heart problems or high blood pressure
Otherwise, help the victim to cool off, and seek medical attention if symptoms worsen or last longer than 1 hour.

What to Do
Cooling measures that may be effective include the following:

Heat Cramps
Heat cramps usually affect people who sweat a lot during strenuous activity. This sweating depletes the body’s salt and moisture. The low salt level in the muscles may be the cause of heat cramps. Heat cramps may also be a symptom of heat exhaustion.

Recognizing Heat Cramps
Heat cramps are muscle pains or spasms—usually in the abdomen, arms, or legs—that may occur in association with strenuous activity. If you have heart problems or are on a low-sodium diet, get medical attention for heat cramps.

What to Do
If medical attention is not necessary, take these steps:
Stop all activity, and sit quietly in a cool place.
Drink clear juice or a sports beverage.
Do not return to strenuous activity for a few hours after the cramps subside, because further exertion may lead to heat exhaustion or heat stroke.
Seek medical attention for heat cramps if they do not subside in 1 hour.

Sunburn
Sunburn should be avoided because it damages the skin. Although the discomfort is usually minor and healing often occurs in about a week, a more severe sunburn may require medical attention.

Recognizing Sunburn
Symptoms of sunburn are well known: the skin becomes red, painful, and abnormally warm after sun exposure.

What to Do
Consult a doctor if the sunburn affects an infant younger than 1 year of age or if these symptoms are present:
Fever
Fluid-filled blisters
Severe pain
Also, remember these tips when treating sunburn:
Avoid repeated sun exposure.
Apply cold compresses or immerse the sunburned area in cool water.
Apply moisturizing lotion to affected areas. Do not use salve, butter, or ointment.
Do not break blisters.

Heat Rash
Heat rash is a skin irritation caused by excessive sweating during hot, humid weather. It can occur at any age but is most common in young children.

Recognizing Heat Rash
Heat rash looks like a red cluster of pimples or small blisters. It is more likely to occur on the neck and upper chest, in the groin, under the breasts, and in elbow creases.

What to Do
The best treatment for heat rash is to provide a cooler, less humid environment. Keep the affected area dry. Dusting powder may be used to increase comfort.
Treating heat rash is simple and usually does not require medical assistance. Other heat-related problems can be much more severe.

Cooling your house the Green way #3... choosing the right fan

6/13/2013

Using fans to cool your home is energy efficient. After you determine the natural ventilation scheme in your home, you can enhance the effect with the use of active fans. When choosing fans, check for efficiency ratings.

Fans are rated by how much air they can move in a given amount of time. The most common spec is cubic feet per minute (cfm). Calculate how many cubic feet are in your house, room, or attic (length x width x height) to find the proper-size fan.
​
Fans move air most efficiently when they have a cowling. Cowlings prevent air around the tip of the blades from circling about outside the blades, instead forcing that air forward, yielding much more air for the same power draw.

A cowling on a fan directs airflow and improves efficiency.
​
Many fans are available at a wide range of prices. Choosing the right unit for your needs can ensure you get the effect you’re looking for.

  • Oscillating fans: These fans move back and forth and work only for convective cooling, and they’re dubious at that.
  • Box fans: Box fans are portable units you can move around as the need occurs. Most have some kind of cowling. Blade design helps determine the efficiency of the air flow.
  • Window fans: Window fans come with a sheet metal mounting that fits right into an open window and seals around the edges. Most of these fans are very efficient. The best way to move air in your house is by using a good window fan mounted into the most appropriate window, probably upstairs on the downwind side of your house (the fan aims out the window). One small window fan mounted properly can do the same work as a number of large fans scattered about the house.
  • Exhaust fans:Exhaust fans shouldn’t be used when the HVAC system is running, but if you need to, open a small window nearby so that you can control the air movement.If you’re cooking in the summer when the AC is on, exhaust fans can make a big impact on the comfort in your house. This is true especially if you’re boiling liquid, because not only does that heat the air, but it also humidifies. Run the fan on high, but crack a nearby window so that you don’t pull expensive, cooled air out of your house.
  • Ceiling fans: Here’s how to use your ceiling fan to get the most benefit:
    • Create convective cooling: With a ceiling fan, you can get convective cooling by running the fan in either direction.
      Ceiling fans work best when the fan blades are 7 to 9 feet above the floor and 10 to 12 inches below the ceiling.
    • Draw the heat up: If you have a vent, you can enhance the chimney effect by running a ceiling fan in the reverse direction (aiming the air flow upward, in other words).
    • Reverse the chimney effect by pushing hot air down: In the winter, you can use a ceiling fan to push hot air back down into the room.
    A well-positioned ceiling fan can allow you to lower your thermostat by 4 degrees Fahrenheit and achieve the same comfort level.
  • Whole house fans:Whole house fans are mounted in the ceiling between a high point in your house and the attic. They draw air through open windows, exhaust it up through the attic space, and cool the attic spaceA great advantage is that you can open any window in the house and get air movement in that room.
  • Attic vent fans: An attic vent fan draws air in from one part of the attic, and out another. There is no air movement in the house below, so attic vent fans can be run when the house is closed up.
