We had no power to our furnace and a/c. Called Dunn around 1:00pm and they sent a service tech by 3:30pm - same day. Dave B was respectful of our home, knew exactly how to troubleshoot the problem and solve our issue. Very impressive service on a holiday long weekend. Thanks to Dave B and the Dunn team.

We scheduled our regular annual air conditioner inspection and Randy came by to do the job. Randy has been taking care of our furnace and air conditioner for years and he is always knowledgeable, professional and courteous. Randy and Dunn provide a service we can trust.

We have relied on Dave to service our old furnace for about 10 years and could always trust him to do a thorough job. His role is now in sales. He is very knowledgeable and conscientious so we felt confident with his advice on which furnace and a/c to purchase to best suit our home! Also the installers, Alex and Gagan, were a real pleasure to have here as they did a very professional job while being very courteous and thoughtful! These employees are valuable assets to Dunn heating! Thank you!

I recently had a problem with my furnace and am absolutely thrilled with how I was serviced by both Mike and Dave in having it resolved. Dave’s technical expertise and attention to detail were reassuring in knowing that the problem would be reliably addressed. I’m also pleased with the extra care taken to inspect the entire HVAC system for other possible issues. I’m looking forward to years of reliable service from both my furnace and Dunns!

Emergency appointment, called a technician arrived quickly to assess. Needed a new furnace. Installers arrived on time on a Saturday, respectful of our home and kitties. Efficient, cleaned up after, made sure we knew how to connect the app and made sure everything was running correctly. Appreciated the install on a Saturday as it is to get cold overnight.
