Real Reviews from Our Clients

Dave's Mechanical provides superior service, commitment to excellence and timely response from initial estimate to installation. Don't turn down the yearly cleaning/service checks that help keep your unit running efficiently.

Dave’s installation was quick, neat, and gave us the heat we needed in our sunroom. He was thorough in his explanation of the unit and remained a resource to us even after installation. We LOVE our heat pump during the coldest days of the winter and enjoy the bonus of cool air conditioning in the summer. Dave is the way to go if you want an economical answer to high oil prices. We are glad we did.

We hired Dave’s Mechanical Maintenance to install heat pumps. They were very professional, trustworthy, punctual and did an incredible job with a complicated and complex install. I would highly recommend them for any oroject. They get 5 stars from me!
