I highly recommend Dennis he is professional, honest and on time. Saved me from spending $20,000 on a new furnace and A/C. I had previously called on another company to see what was wrong and they insisted we replace both the furnace and A/C. Called Dennis for a second opinion. He looked at the furnace and repaired with in a few minutes. Confirmed I didn’t need to replace my furnace. So glad I called Dennis!

We contacted Dennis last minute with a furnace problem in preparation for a cold weekend. Dennis was able to come out, after hours, to complete the repair the same day! He was professional, courteous and friendly. The repair was made quickly and reasonably priced. We will definitely be calling Dennis for all our future HVAC needs! Highly recommend him!

Dennis has been my only heating and cooling professional for the last 10 or more years. He is always professional and doesn’t mind all of the assistance my dogs give him the entire time he is here. When my old furnace cracked and had to be replaced Dennis knew my budget was always tight as a single parent and he walked me through my choices and offered advice as if I was family. I trust him and his decisions on my behalf. I recommend him for both spring and fall checkups and assure you he will never tell you something needs fixed if it is not needed.
