  • “Averill heating and cooling did a great job from start to finish. Our new furnace works great and we love the new up to date thermostat. I’m sure our ac unit will work just as well this next summer.”

  • “Averill Heating & Air Conditioning is a very professional and reliable company. I called early this morning when my furnace quite working and they arrived within a half an hour. Jack and Shannon were very polite and resectable and I felt right away that I was in good hands. They cleaned my furnace and fixed the problem and had it up and running in about one hour. My furnace is about 18 years old and they suggested that I may consider replacing it soon, but they didn’t put any pressure on me at all. I was so grateful for their fast and efficient service. Their fee was very resonable and I would definitely recommend them to anyone.”
