Thermostat installation
April 26, 2026
In December 4, 2025, I bought new Carrier infinity system control thermostat & got the installation from your technician Steven Wood. The total cost & services was $ 1750.00. So far, the thermostat is working ok but the function to connect to data server & OTA server are not working therefore I m not able to access it via the app. The technician came back & forth at least 3 times to update software but still not able to make it work. I m not sure this is the malfunction thermostat or not. I m really patient to wait for the technician to figure out. I believe the thermostat is still under warranty. Please help by sending some else to solve the problem. Thx

Good Experience
April 22, 2023
I had a good experience with Steve's. I needed a complete heating and cooling system replacement. Sales Rep Blake did a great job assessing what options would work for my house and running me through them. The install crew (Rich, Joel, and Fernando) were courteous and quick, and worked around what was essentially a full house of kids. I will use them again for my household needs.

Excellent performance by everyone one at the company. Installers Fernando and Jorge were very polite. They even made an unrelated household repair. Very satisfied from the estimate to the installation. During the estimate process Blake answered all my questions and provided helpful options.

Great Overall Experience
May 31, 2022
Steve's Five Star Services provided us an overall great experience in purchasing a new Carrier Infinity Furnace and Air Conditioning System. They also re\-ducted our upstairs air ducts as well. Their technicians were knowledgeable, very professional, and answered all our questions. The system was installed and passed test without any issues. Everyone we dealt with from Steve's was terrific (sales, office staff, installers and testers). I would highly recommend their services.

Money well spent
May 26, 2022
We had our entire HVAC system replaced on May 16 \& 17 of 2022 with a Carrier 4 Ton system and we are overwhelmed with its performance and efficiency. The system cools the house quickly with little to no noise, the heating system has no noise. We are pleased with our choice of HVAC system and we are happy with the installation company for their excellent installation service. We definitely recommend Carrier and Steve's Five Star Service for any HVAC needs.
