Indoor Air Quality: Your HVAC Makes a Difference

Your HVAC system can do much more than heating and cooling. With proper maintenance, you can make your home a healthier place to live.

Prevent Mold and Mildew

Mold and mildew don’t just make your home smell a little musty. Mold spores can be harmful to your health. It works like this:

Mold and mildew reproduce by generating tiny spores. These spores float through the air, and circulate through your HVAC system. For some people, these spores can cause an allergic reaction. Typical symptoms are red and irritated eyes, runny nose, and possibly even a rash. These symptoms are worsened if the person already has a respiratory condition like asthma.

Your HVAC system can be fitted with filters that screen out these spores. Combined with regular system cleaning and maintenance, an electronic air cleaner can make everyone in your home breathe a little easier.

Control Dust and Pet Dander

Like mold and mildew, dust and pet dander in your home can make life miserable for your sinuses. The good news is that the same high efficiency HVAC filters that take care of mold and mildew also do a great job cutting down the free-floating dust and pet dander in your home.

Control Humidity

We all know that dry, cold air in the winter makes crossing a carpeted room a shocking experience, while hot, damp air in the summer is sticky and uncomfortable. The humidity in the air also affects how much energy (money) is needed to maintain a comfortable temperature. Moisture in the air tends to retain heat, so that humid summer air is harder to cool. During the winter, the opposite is true: dry air loses its heat quickly, making your furnace work overtime.

A variety of ancillary products on the market today can help maintain stable humidity levels in your home. A basic service schedule of maintenance and check-ups will help your heating and air conditioning system run at peak efficiency year round.
