There’s more in the air than you can easily see—particles, dust and smoke, all of them potential triggers for asthma and allergy attacks. Particles like dust, smoke and bacteria are often .3 microns or less. At that size, allergens can get deep into your lungs because they aren’t filtered well by your nose and throat.
- Set the thermostat as high as comfort will permit.
- Make sure attics are adequately ventilated to relieve heat buildup. If necessary, improve airflow by adding or enlarging vents.
- When building a new house or renovating an old one, choose light-colored roof shingles to reflect more of the sun's heat.
- During moderate weather, don't use the air conditioner unnecessarily.
- Draw blinds or drapes to block the sunlight during the hottest part of the day.
- Install awnings over windows exposed to direct sunlight.
You would’t drive your car 100,000 miles without changing the oil. The same logic holds true for your home comfort system. Regular HVAC preventative maintenance is the best way to ensure trouble-free operation and peak performance. Preseason maintenance is also important. It can help to avoid a system failure in severe hot or cold weather when you need it most, and it can also keep your energy bill from getting out of control.
