Heating & Furnace Repair

When the nights turn colder during the winter, it is not the time to have your furnace or heating system act up! Donnelly Heating & Air Conditioning is here to ensure that your family is kept warm and comfortable during our winter months. Donnelly Heating & Air Conditioning’s technicians can service / repair any brand of furnace, and if you are looking for a new system we offer superior products with high efficiency ratings (AFUE) that can substantially lower your utility bills!

Indoor Air Quality

The EPA has shown that the air in your home can be several more times polluted than the air outdoors. Today modern homes excel at sealing out the elements, but this in turn recycles toxins, bacteria and mold into the air you breathe. We provide indoor air quality products that integrate into your HVAC system and work together to purify your indoor air. Learn more about Indoor Air Quality Products
