"Changing my 5 star review to 2 stars. We have had a HE Boiler as well as a AC/Heat Pump installed by them. Unfortunately we needed service today. I was willing to pay for Emergency service. They said they couldn't make it out for 14 days, because we did not have a service contract. Spent about $25k for the installations. Which apparently means nothing to them What makes matters worse, the Emergency Service we paid through another HVAC provider was only necessary because of an issue they created during the installation. During the installation Speer Air originally ran the line for the residual pump over the copper hot water line. Which over time burned through the residual line, and then cause a hole and leak on the copper pipe."

"I called Tony and he told me he didn’t have anyone available. He asked me what was the issue and I explained to him and he told me he can walk me through it. After walking me through how to fix it my heat came on. Tony was absolutely amazing and it took 10 minutes to fix. Will definitely hire him if I need more work done. "
