Customer Reviews
What our customers are saying

Thank you Kerry and the installation crew for the two new heat pumps, for installing during a snowstorm, and for leaving the house as neat and cleared of all debris. I am more than pleased with the high quality of work from professional timely estimate to installation. Job well done guys. I highly recommend Dave’s appliance for your heat pump needs. Keeping business local with a professional crew located in the small town of Winthrop!

Paul D

Dave’s did a fantastic job cleaning my heat pump this month. The tech cleaned and tested my heat pump and made sure we will be sitting in cool comfort this summer! Thank you Dave’s Appliance! They also installed a new multi split at my house in November. Good install, clean and professional! Thank you!

William B

They are a wonderful crew. Efficient, personable, helpful. Probably best crew I ever had do work for me.

Sylvia I

I am building a new home and had Dave’s install 2 heat pumps for me. I could not have been happier with my experience. From the customer service to the installation and the product itself, they are all fantastic! So happy I chose to work with Dave’s!

Kelly T

We want to compliment your team of installers for the work they completed on our new heat pump. They were very focused on completing the job, courteous, and kept disruption to a minimum. We are extremely happy with the outcome.

Chris K

Dave’s was really good to work with! Right from the beginning to the end, ti was an easy simple
meeting at the beginning, he considered the most efficient ways to install it, the crew who came out was very professional, all the line sets were very clean in the installation.


Dave’s appliance did our heat pump system on our new construction home. Their quote was the best, the crew that did the work was easy to work with and responsive when I had questions/concerns. I built the house myself, and I admit I was probably a pain in the butt to deal with at times, Dave’s did excellent work, I highly recommend them!

Tom V
