Arrived exactly when they said they would and finished ahead of schedule. Upon completion of aforementioned exterior brick work, the Pro HVAC System crew returned to reinstall our system. Not only did they put it all back together, but also cleaned up the compressors and rerouted the cable internet lines to make it all look professional and tidy! All new copper piping was used to reinstall our split system. Following install, they swiftly collected all discarded materials and left my property cleaner than it was when they came in. Their pricing was more than fair. They conducted themselves in a very professional manner. I can not emphasize enough how much I appreciate people who are punctual and do good work. Would not hesitate to call them again should we experience any issues. Our system has been working flawlessly since the reinstall.

I was impressed by his ability to identify where the potential issue was coming from and explaining it thoroughly.

In addition, his pricing is reasonable and I appreciate his service.

Kevin dispatched Paul and his team to remove, clean (off-site because our building required it), and re-install our PTAC units, and I could not be happier. They were so careful with our home, furniture that needed some moving, and the PTAC units, and when they were done, they left our home the way it was and cleaned up after themselves. The units are now squeaky clean; I don't hear a sound! The price was reasonable and honest. I'm happy I found a trustworthy, thorough and meticulous company to care for our PTAC needs. I'll be a returning customer!

They took away the old unit and cleaned up afterwards. We also ended up upgrading our thermostat. John was accommodating and sent Seth back at a later time (after we received the new thermostat) to install the new thermostat. It took a bit to get the heat pump working but ultimately it was all done and John and Seth stayed to make sure both the AC and heat pump was working.

Something has changed drastically and for the worse in the last year. Since 2020, they have installed a generator and two separate cooling and heating systems in my home. I've spent literally 10s of thousands with them. Issue 1: They have purchased the world's most obnoxious AI system to answer their phone. Yesterday I called during regular business hours. The AI- 'Rachel' would not put me through to a human, laughed at me (YES!) and insisted it could handle my issue. It literally gets condescending and snarky. Issue 2: The quality of their work has fallen off. New heating installed in September. Turned on in December. No heat to an entire floor. The fans weren't installed correctly. New AC installed last June. Not working. Really? Waiting on service call later this week. Issue 3: Add on charges for everything. For instance, with the AC service call this week, which I am only using them for because they installed it and should be responsible, I was told (even though I purchased a service plan and the system is still under warranty), that it would still be $94 plus for the call if it is something not covered by installation or warranty. The $400 service plan plus $94 would more than cover a call from another company and..... what could it be besides faulty equipment or an installation error like the heating? I had similar issues with generator problem in February. Paid for the service call, he didn't have the part and they wanted to charge a second service fee when he came back. I have recommended them countless times to others. I will be finding a new vendor once the AC issue is resolved. So done.
