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. Miguel text when he was on his way, showed up right on time and was equipped and wore shoe covers. 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!

I recently decided to transition from a gas water heater to a Heat Pump Water Heater (HPWH) and…read morerequested quotes from several local vendors, including Irbis. The Consultation Process Justin, their sales representative, was efficient and thorough. He patiently walked me through the entire process and was (more than others) knowledgeable about the SJCE rebate and loan options--even providing valuable information I hadn't found on my own. After the initial visit, the Irbis team was very responsive to my follow-up questions and accommodated my request to switch the quoted Rheem model to a GE Geospring model. I also appreciated that they offer an optional 3-year labor warranty to pair with the equipment warranty, which provided extra peace of mind for a reasonable fee. The Installation The installation day turned out to be quite tricky. It actually took three different tanks to get the job done; the first two arrived with small dents on the body. It was a bit strange, as the packaging seemed intact, suggesting a manufacturing or handling issue. While this delayed the process significantly--stretching the job into the late evening--I was incredibly impressed by how the team handled it. There was absolutely zero hesitation to replace the damaged units, and no one tried to convince me to just accept a dented tank. Despite the long day, the installers remained patient, professional, and pleasant. They did a neat, tidy job and thoroughly walked me through the operation of the new system. The only minor critique I have is that I wish the team had tested the incoming water pressure prior to starting the installation. Final Verdict Overall, I am highly satisfied with the level of service and quality of work from Irbis. They aren't the cheapest option on the block, but they have value added process to handle the permitting and SJCE paperwork completely, making it a hands-free experience for the homeowner. Most importantly, when unexpected issues arose, they responded effectively and with great integrity. I would recommend them for a stress free conversion

My Fiance chose Irbis HVAC to replace his ducting in his home in Saratoga on May 18-23, 2026…read morebecause the company was offering a 20% off advertisement for replacement work when he signed up for the monthly service plan at $24.95. When he and I inquired about the advertisement with Irbis HVAC employee Natasha upon receiving the final bill, ....we were quite shocked for Natasha to tell us that this was not applicable to our order!. When asked specifically why it was not applicable based on replacement work stated in IRBIS advertisement, she Couldn't give us an answer other than. Your work order has already begun. Glen asked her again and told he wanted to speak with the manager. He emphasized and repeated to her that he had tenants jn this home when the work order began with Irbis. He also told Natasha that the technician never offered him the monthly service plan advertisement which included 20%. Natasha said she would speak with the manager and get back to us. We were again very disappointed when Natasha called us back to learn that the manager was not going to honor the 20% off for signing up for the monthly service plan. We both several own rental properties and were looking for an Hvac Company that we can have a long term relationship with based on mutual trust. This was disappointing and I want to let all consumers know about this experience so they can advocate for bate and switch, false advertisement tactics by Irbis. Jenny and Glen Tim, Thank you so much for your quick response to unfortunate experience we had with your misleading "bate and switch" ad. Business ethics are at the utmost importance behind this complaint. Therefore, I am bringing it to the consumers attention for two reasons. When you practice "bate and switch" you drive consumers away from your competitors, misleading the consumer that they WILL receive a 20% off discount for SERVICES. The result is, you inadvertently hurt the entire HVAC industry by driving business away from smaller HVAC companies that may already have a 20% to 30% lower price point originally. Lastly, it leaves the consumer feeling "deceived". Per your request, We have attached the text message ads from your Company IRBIS HVAC stating, "SAVE 20% OFF YOUR SERVICE BY JOINING OUR PLAN" that were sent via text to our cell phone over nine times between May 12th, 2026 until May 21st, 2026. When we tried to join your "Plan" and follow the text ad.....Natasha, at IRBIS, stated that the discount won't apply to us for the $22,000 job we hired you for. I'm sure you can understand our surprise and disappointment. Thank you again for your time and concerns regarding this serious issue. All the Best, Disappointed

After meeting in person with numerous HVAC companies, my wife and I decided to move forward with…read moreCalvey Heating and Air. Michael Calvey thoroughly explained all of the options for our house's specific HVAC needs and was very patient with me as I asked a variety of questions. In fact, he made numerous trips to our house to answer the constant flow of questions my wife and I had. Bottom line, we built a solid working relationship with Michael and this gave us the comfort we needed to move forward with our HVAC investment. Calvey Heating and Air's estimate for a new heat pump and furnace at our house was very competitive. I was amazed at how much the pricing varied from vendor to vendor. Michael and the Calvey team made the entire process seamless from start to finish. Michael recommended an electrician who did a great job with our electric panel upgrade and the permit team did a fantastic job working with the city for all of the required paperwork. When it came time for the installation, the lead installer, Servando, and his team took pride in their work for the two day install. Similar to Michael, they were patient with me and answered all my questions during the install. Following the install, the Home Energy Rating System (HERS) Team promptly arrived and conducted the necessary testing. Lastly, the permit team met with the city building inspector to successfully get the city sign off on all of the work. Throughout the entire process, Calvey Heating and Air did a great job choreographing and managing all aspects of the installation. I was constantly kept informed and Michael and his team visited our house daily during the installation to ensure all was moving forward properly. Lastly, a final walk-through was conducted by Johnny from Calvey ensuring that the install was 100% perfect. Once my wife and I have had time to work with and get familiar with our new system, Michael indicated he will have his team come by our house and balance out our vents if needed and answer any additional questions we may have. Overall, my wife and I cannot be happier with our decision to have Calvey Heating and Air install our new system. Their service was great from start to finish and there were no hiccups. We highly recommend them. Thank you Michael Calvey!

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.

Michael Calvey was a joy to talk to. Thank you to Johnny, the project manager, and the folks from HOPSTER that facilitated the post-installation test and inspectioin. 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. I will continue to use Calvey for annual maintenance

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.
