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.
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.
