Air quality in your home is a prime concern for you and for us. At Key Heating and Air Conditioning, we understand that as more houses are built airtight it is even more essential that you address the air quality.


Dust, dirt, pollen, mold, bacteria, and algae are pulled in by your HVAC system to your home and breathing area. Key Heating & Air Conditioning Inc. install air purifiers that will remove pollutants, including mold spores and pet dander, from the air inside your home.


A great option for those who suffer from allergies or asthma, whole-home air purifiers are installed as part of your home’s heating and cooling system. These home air cleaners remove polluted air from throughout your entire home.
