They looked over the job, and suggested installation improvement as compared to the system that was being replaced. They were neat, efficient, and professional in every way. If I have their names correct, Thank you to Yng and Shin for expert, professional, courteous installation!!

    These guys came in highly recommended by a personal friend. Called them up to have our split…read moresystem removed the have brick work done. They sent over a crew of two. 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.

They were on time, respected my wishes on removing their shoes, and they clean up after the installation. I was pleased with the outcome come. They tested the units and gave me a quick tutorial on how to use the units. I also included photos of the finished job. We'll recommend. Thanks to the team.

He came to take a look at the space and provided his recommendation and promptly sent us the quote after. We had gotten quotes from multiple places and their pricing was fair. He was very responsive and answered all of the questions we had. For any questions he wasn't able to answer immediately he got back to us promptly with the answer. Seth and another guy was responsible for installing the unit on the day of. John came by to make sure the installation was going okay. The guys were quick and efficient with the installation. The job itself was very clean install of the unit and they covered the pipe going down the side of my house so it looks a lot better! They completed the installation all in one day, which was great! 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. So we were very happy with how the project was handled and completed.

Oscar came first thing Monday morning to assess the situation and returned with the new unit and Thomas. They worked for several hours to install unit, explaining how it all worked. In addition, Thomas used my shop vac to vacuum up most of the standing water. Above and beyond!!!

    I've used this company for years. Their strength was their personal service, family owned. I…read moretrusted them completely. When I called, the receptionist and I were on a first name basis. 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.
