Had the heater replaced as well as replacing the ducts. Joe and his team did a fine job and the new system is keeping the house warm. We're also looking forward to the AC in the summer for the first time.

HVAC systems are very complex these days. Joe of Giant HVAC carefully explained all the various ways to go. Installation was fantastic. Very honest and straightforward. Highly recommend.

★★★★★brandt frankiea year agovia Google

Joe and his crew were great. He gave me several good options for my HVAC replacement, even one that allowed me to keep my current gas furnace. Joe was on time and responsive. He answers all my questions no matter how trivial. I will likely have more work done with him the future.
