    Whole House fan installed in the upstairs hallway
    Matt I.

    Great service both during my HVAC upgrades and post-installation support! Tony and his team did an outstanding job upgrading my 40 yr old HVAC system (2 furnaces & 2 AC units). Additionally they installed a whole house fan (highly recommended) to save on A/C costs during the summer. They provided very a detailed proposal with several options for upgraded units and pricing was competitive with other offers. Their work was outstanding as they sealed off the entire garage during the demo with a negative pressure system to avoid any asbestos contamination. The entire job was completed in less than 3 days start to finish and the quality of work was impeccable. I am writing this review 5 years after the initial installation as I recently needed some help on a minor issue. Tony was on top of it and came out at moment's notice to address it at no charge.

    Great service, very knowledgeable, reasonable price. I would highly recommend Tony for any HVAC related project. He and team is extremely knowledgeable and always available when you need them. I have been using their expertise since past ~8 plus years and he never disappoints.

    I had an excellent experience with Henry from ThermaTech. My HVAC system stopped working properly…read moreafter another company had spent about two hours diagnosing it and quoted me more than $3,000 for a new control board, contactor, transformer, surge protector, and maintenance plan. Henry arrived, clearly explained each step of his diagnostic process, and quickly identified that the transformer and contactor were the actual issues. He completed the repair in about an hour and charged me $540 total, saving me roughly $2,500 compared with the previous quote. What impressed me most was Henry's honesty, expertise, and transparency. He did not try to upsell me or replace parts that were not needed. He took the time to explain what had failed, why the system was not powering on, and what he was doing to fix it. It is rare to find an HVAC company that combines strong technical knowledge with fair pricing and integrity. I would absolutely recommend ThermaTech to anyone looking for an honest and skilled HVAC professional.

We had no idea when it was last serviced or if it had ever been serviced at all. Henry gave us a very fair and competitive price for a tune up. Upon Henry's arrival, he was friendly and professional. He opened the furnace and showed us the burner. He explained it was in great condition considering the age of the unit and it didn't need servicing; although, he did clean up around a few areas around the burner. The blower motor was slightly wobbly, and once again, he explained it was still in good shape considering its age. He proceeded to the back patio where the condenser was located. He noted the unit was very old and that particular Freon is no longer available for servicing; however, he stated the unit did not need to be replaced just yet as long as it's blowing cold. Henry indicated despite our units being way past their anticipated life expectancy, they were clean and blowing hot & cold just fine. Therefore, no servicing was recommended and he did not charge us anything. We are impressed not only by Henry's friendliness and professionalism, but also by his transparency and integrity. Many other companies would have hopped on the opportunity to upsell the service or even sway us to replace our system right away, but Henry gave us peace of mind to give us time and to save up for an inevitable replacement in the future with Therma Tech. Thank you so much, Henry! We will definitely contact you again in the future and recommend you to all our family, friends and coworkers.

I wish I had written down the name of the operator who scheduled my appointment but she was polite, professional, and courteous. She went above and beyond to find an appointment that worked with my schedule. She called back as promised and I was never left hanging or waiting for information. 5 stars for the operator, thank you! My technician was Victor who arrived during the scheduled time window. He was very knowledgable about the HVAC systems used for the homes in my neighborhood. He was able to quickly confirm the issue, diagnose the problem, and find a solution. He then performed a series of tests to confirm the issue had been solved. During each step of the process he explained what was happening in a way that was easy to understand. I now have a much better idea of what my system is doing and how it operates. 5 stars for Victor and I'm grateful for his service.

Not only did they not listen to my needs, the whole time they offered solutions that cater to what they want instead of what I want. 1. They recommend dual zoning which cost about the same amount as installing a new mini split. I have a single state HVAC which isn't recommended for dual zone install. 2. They keep pushing for fixing/upgrading central instead of installing mini splits. 3. They keep asking for my budget (red flag), talking up high end units (red flag), talking down low end units (red flag). Look, we all know Mitsubishi and Daikin are the top of the line. However, the cost of DOUBLE of the price of lower end models isn't due to just superior quality and technology. Heat pumps and mini splits are not new technology. One isn't vastly superior to another. Yes, it may be better, but not double the price better. The cost are always due to the commissions and kickbacks for these installers. That's marketing and salesmanship, but please be more transparent next time. Finally, I asked for quotes and options so I can decide. The person walked away disappointed and I suspect they think they lost a sale because of the way I did not want the highest end models and stayed firm with my mini split request. I sensed the guy walked away disappointed. Yet I still expected a courtesy quote like the other installers. They never sent it. I was not surprised. In the end, I decided that a whole system upgrade to mini-splits (30% more efficient just from being ductless alone) with rebates made more sense instead of add ons to existing system. But these guys did help me cross them off the list and went with the installer who actually listened to my needs and gave the recommendation and options that I wanted. I do not recommend these guys. They will push for the highest cost system and will ghost you if you appear to be knowledgeable enough to call them out on it.

We wanted to add an additional vent on the main floor, and some dampers for a few of the vents and everything went like butter. Lex and Maxat were the nicest people, arrived on time, left at 6pm each day leaving the house clean. It was a 3 day install and they finished on the third day.

They hit another home run when Isaiah and Monty were assigned to a plumbing issue at my house. It was a hectic week to start, topped off with a backed up toilet that started to overflow.

Given that I didn't have to wait days for an appointment, I agreed to the price, which was initially high compared to others. That being said, it ultimately became roughly the same, if not a little cheaper, than other places that charged by the hour or quarter hour, as the job was a little more complex than initially thought. The guy spent almost 2.5 hours here to change out two bibs (again, way more complex than he probably thought), and he did a wonderful job. My problems were addressed same day, same visit. If I chose other plumbers, I would have waited days before my items were addressed. I've used Jazz before with my older AC unit, and they will always have a spot in my contact list if I need help with my HVAC or plumbing.
