Our Happy Customers
Fariborz Ebz2025-08-18Trustindex verifies that the original source of the review is Google. Our furnace broke down, so I looked up heating services and found Onsite Heating & Cooling. I called and talked to Shawn, who told me they could send a technician in 3 hours, such a relief to get help that fast! Sure enough, the tech showed up exactly on time. Turns out, our 30-year-old furnace needed replacing. The technician walked me through all the options really thoroughly, and I ended up deciding to replace both the furnace and A/C with a heat pump system. A few days later, they came for the installation. By the end of the day, they were done. They were super professional and did an amazing job. The quality of the ductwork, plumbing, and wiring was top-notch. They also cleared out all the old equipment and left my place spotless. Honestly, my experience with Onsite heating and AC was fantastic. I’d highly recommend them! Thank you Shawn and the the entire team!!!
