Get matched with top geothermal heating or cooling system installers in Seattle, WA

"The employee called me a sandn*gger. Do not hire these ppl."

"Aside from a hiccup around scheduling some ancillary repairs the quoted price was reasonable and the work was done to spec."

"A tech "Graham" came out for an annual maintenance visit on a reliable 15 year old York Furnace with a 20 year guarantee on the heat exchanger which Blue Flame installed in 2010. He could not explain why he was here, and when I told him "routine annual maintenance" he said, "Let's see what we can find". That was the first sign we had opposite agendas. It went south from there. After lots of loud grinding noises, he supposedly found a shiny jagged gash which he showed me on a scope. I am extremely suspicious he created it himself with a power tool. The end result was the furnace was no longer usable and cost me $8K to have them replace. To add insult to injury that guy ruined my screen door, which won't close anymore. I have ended my 15 year relationship with this company, since I no longer trust them."

"I won't call any other heating or AC experts ever again. Twice now, I've had incomparable experiences. I had another highly reputed company come diagnose my failed furnace and provide an estimate, but AirPros' price for the same part and repair was much more reasonable and furnace repairs are not cheap, so the difference mattered significantly. AirPros also treated me like family. Go with this family business, you will be happy."

"Our Greenwood Technician, Sam, really provides us assurance that our gas furnace is still functioning adequately, but detailed why it may be time to consider replacing our aging water heater and furnace water pump system before likely damage occurs. Sam is a most genuine and reassuring professional - He helps us know just what may need maintenance and what is still sound. It is a joy to work with a trustworthy and competent professional "

"Everything went fine, they even came in a year later to make sure the system was still working well. Very happy with job performance."

"They were very professional, punctual and did great work! Best service! Highly recommend using Cardinal Heating!"

"This company relies on AI and is not truly available 24/7. They sent a technician to my home who was unable to fix my issue, yet claimed it had been addressed. I called back immediately, and their AI bot booked me a new appointment that evening. The technician never showed. I called again over the course of the next two days, with no resolution. I received multiples text threads over the course of the two days stating that my concern had been escalated to the "on call manager," who never called. Today I spoke with the company and they said that there is no one in the office over the weekend! Despite my horrible experience, they refused to refund the cost of the "service." Take your business elsewhere!!!"

"Best company to work with. Very professional, on time, polite, and unbeatable price."

"Very expensive and overprice, just to change an Outdoor Garden Faucet that cost $32 at Home Depot, I paid $694.99, this is what you call HIGHWAY ROBBERY."
