Henry is the reason why Therma Tech supersedes all the other HVAC businesses. We have an ancient…read morefurnace-condenser system. 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.

Decided to call a few for a quote and connected with ThermaTech. They were very responsive and easy to set up, confirmed that they know to work around the specific model.

Professional - talked me thru what he was going to do and was ant to make changes and asked me to confirm the airflow was good. Was very patient and let me check all the air vents multiple times - a very thorough job. Paid right when he left and at a very reasonable price. Will definitely call ThermaTech again and highly recommend!

Michael came out to my house and walked me through the pros and cons of a heat pump HVAC. For my home, the extra money made no sense. I really do not need central AC. We then talked about a new Carrier, high-efficency furnace. That was exactly what I needed. I also opted for the Ecobee Smart, wi-fi enabled thermostat. I am extremely happy with everything. The price was right. The installation was flawless. The post-intall QA walkghrough, by Johnny, went really well. ThenI worked with the folks that checked all the boxes post-intalleation.

From start to finish I met with Michael on February 12th. The 16th the new furnace was intalled. February 17th Johnny did the QA walkthrough. February 18th HOPSTER did their pre-test and inspection walkthrough. The HERS test was done February 23rd. March 5th the city inspection was complete.

From the start, the owner took the time to walk through multiple options with me, explaining the pros and cons of each. He was thorough, patient, and ultimately came up with a smart approach that worked well for the layout of the house. The installation crew was excellent. They were professional, friendly, and clearly very knowledgeable about what they were doing. They also took care to keep things tidy and picked up after themselves each day, which I really appreciated. On top of that, the pricing was competitive compared to other quotes I received. Overall, a great experience and I'm very happy with the results. I'd definitely recommend them to anyone looking for HVAC work.

December 2025 our furnace stopped working. I found Art of Comfort on Yelp and called for a…read morediagnostic appt. I went through the automated system by phone and an appt was scheduled the coming Monday - fast. I don't like automated systems and this system was unlike the others for cable, healthcare, etc., this one actually WORKED on every single thing the first time! I usually have negative sentiment towards a company after using their poorly designed automated system, not this one - I had positive sentiment. I got the text confirmation immediately. In the coming days I received the expected and timely reminder, and "heads-up on the way." David showed up in the arrival time window professionally and wore booties over his boots inside our house. David assessed the error code, confirmed the issue, focused on safety and then gave me the bad news. First, it was going to be expensive - an induction motor replacement. Second, though it was going to be expensive, he didn't recommend I hire him. He thought I'd get better (faster, more efficient, happy) service for my brand of furnace by working with an authorized factory service company, given that it was this particular manufacturer. Apparently, if he called in for part availability, it's a job he certainly can do, that's not the issue, the company would be slow to respond to him because he's not an authorized service company for my brand - YET. He is for another brand, just not mine - YET. This would add friction to the process, to the point of not accepting as credible the assessment (we had a code, mind you) of an experienced HVAC pro. He didn't want me to go through this. It wouldn't make me happy and it's possible it would just delay - without heat in winter - the inevitable of having to go the authorized service route in the end anyway. I will say that using Yelp I found an authorized company I liked. (I called two companies, the first one was in town and a mile away and I was not impressed. The next was a couple cities over and I used them.) I was not charged for the diagnosis. THIS IS LONG TERM THINKING AND TRUE, OLD-SCHOOL CUSTOMER SERVICE! I not only recommend Art of Comfort though I did not have more than the diagnostic piece done, I have saved their number for the future and will share it with friends and neighbors. Our house has two separate furnace / AC systems. I had them installed new in 2006. Something is bound to go wrong after 19 years and I have David and Art of Comfort on speed dial. Thank you David!

So far, I'm very impressed with the service and professionalism.

No scare tactics. No "while I'm here" nonsense. And he didn't charge me a single dime. That level of honesty is unheard of these days. If you're looking for an HVAC company that actually puts integrity first and doesn't try to sell you something you don't need, this is the one.
