    Hector & HVAC team member.
    Joel S.

    With the last few summers breaking heat records, we knew that we needed to do more than our current Sunsetter Awnings and blackout curtains to keep our West San Jose home cooler in the summer heat. Hector was prompt to give me a quote for a new air conditioning system. Hector was very patient in answering our many questions and we never felt pressured or sold. His quote wasn't the least expensive nor was it the highest price, but we felt confident he would provide the best value. On our scheduled A/C installation day, Hector & his team arrived on time. We walked through the entire project discussing how and when various components would be installed. We discussed our concerns with Hector and he patiently listened and took them in to consideration during the work day. He and his team worked in a low key and unobtrusive way and also taking care to cover flooring areas where they were working. As promised the installation took less than a day. At the end of the project, they thoroughly explained & tested the system. My wife loves the new digital thermostat and it's easy to read display. Although, the hot days are a few months away, we feel the peace of mind that we are prepared for the hot months ahead. Our experience with Hector & Cobalt Heating and Cooling was excellent. I highly recommend Hector & team for your HVAC services!

    I highly recommend Hector and his team for anything HVAC. He's very knowledgeable, easy to talk to, and responsive. This review is overdue, but Hector's helped me install multiple HVAC units, zoned systems, duct work, etc... and consistently and reliably delivers quality work. He takes the time to explain what he did, and works with you on the best option for your situation. He is the person you want to go to

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.

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 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.

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 really appreciated that because it helped me avoid spending unnecessary money on repairs. Eduardo carefully explained my AC issues and provided clear, step-by-step solutions. He also went above and beyond by helping coordinate with other contractors, including the roofer, to make sure everything was done correctly for the exhaust pipe installation through the roof. Overall, I'm very satisfied with their service. I also signed up for their annual maintenance plan, which includes annual checkups for my AC and water heater, filter replacements, and ongoing maintenance support.
