Limited-Time Heating Diagnostic Only $69 (Regularly $149)
EXCELLENT Based on 121 reviews Posted on יניב אליאסTrustindex verifies that the original source of the review is Google. Our old AC was constantly causing issues, so we decided to replace it. After getting five estimates, we chose Top AC — and we’re very happy we did. Ethen was professional, honest, and great to work with. The price was fair and right in the middle of the market. The team arrived on time, did a clean and proper installation, and coordinated smoothly with our roofing company during our roof replacement. Highly recommend Top AC — reliable, professional, and excellent service.Posted on Orit RavidTrustindex verifies that the original source of the review is Google. Can’t recommend TOP AC enough! My heater stopped working and they showed up the same day I called, diagnosed the issue quickly, and had it fixed right away. Super professional, honest, and the price was very fair. Such a relief to work with a company that’s reliable and efficient. I’ll definitely be using them again.Posted on Gary BatchleyTrustindex verifies that the original source of the review is Google.

Our furnace kept cutting out and Ethan was very helpful and responsive on the phone. He sent Frank out and Frank was fantastic. Fixed it (fuse sensor) and answered all my questions and charged what they said they would. Will definitely be using them again.
