"Great! The workers are very professional and punctual. They installed a tankless water heater. They cleaned everything up when they were done and then explained how it worked and how to maintain it throughout the years so it would work better. I highly recommend this company."

"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."

"The experience was great. The tech arrived on time, replaced my timer programmed and tested it."

"From the estimate to the final installation you won’t find a more professional company. They installed a new carrier furnace and air conditioner and did an excellent job. I highly recommend them for any of your HVAC needs."

"They installed a minisplit cooling system, with 3 exchanges June 2021. Since then it is not operating the way it should. In my bedroom with the door closed at night on cool at 70 degrees the humidity goes up to 80%. I wake up uncomfortable, change it from cool to dry mode. The humidity will go down into the 50% range but the temperature drops down to 62 or less! So in cool or dry mode I can't get a good nights sleep! They come and look at it and tell me everything is fine. I'm going to buy a window air conditioner tomorrow which seems insane because i spent $10,000 on this minisplit AC system!"

"Excellent technicians. Friendly, competent quick, flexible and professional. Could not recommend more!!!"

"Good professional work!"
