Electric Furnace / Forced Air Heating System Installation
$14,500
We recently had a new heat pump system installed and couldn’t be happier with the experience. The team was professional, knowledgeable, and extremely organized from start to finish. They explained the entire installation process clearly, handled all the ductwork, electrical, and line connections with precision, and kept the job site clean throughout the project. The new heat pump runs quietly, heats and cools efficiently, and has already made a noticeable difference in comfort. You can tell they take pride in their work and pay attention to detail. Thank you !!

Had a great experience with Diamond HVAC. They really came through for us when we needed help fast. Mike and Oscar were super professional, friendly, and very accommodating. Everything was handled quickly and smoothly, and they made the whole process way less stressful. Highly recommend
