    • Brent quoted me a fair price on a replacement furnace & A/C in a side office off of the garage in my home and Nathan & Robert performed the removal & install. They were on time & professional every step of the way. Explained everything they were doing & cleaned up after they were done. I couldn’t be happier with Dunn & would recommend them 100%

    • Bryan came out to do a furnace check - called in advance - was prompt - polite when arrived - put on booties to protect carpet - very thorough and did explain things to me. I would use them again and again. They follow through with what is promised. You can't go wrong with them and especially Bryan's service.

    • Brett and his team did a fabulous job installing a new furnace and water heater for us. They were flexible with scheduling to meet our needs and the quality of work and clean up afterwards was superb. I also feel the pricing was very competitive. I will definitely use the team for my future H&C needs. (Also, when the county inspector did his inspection, he too complemented the quality of workmanship he saw).

    • Friendly and quick service. The response time was impeccable. Tech was very informative to my questions. I'll use your services again in the future for routine maintenance. Thanks Joe

    • I've called on them twice now and have been impressed with how quickly they come and their ability to diagnose the problem. I think their prices are fair given how quickly they can resolve an issue. They are definitely the ones I would call on in an emergency!
