"Cummings did great work. Will use them again."

"Innovation HVAC did an absolutely amazing job replacing my heat pump. What I loved most was how communicative they are. When I received my quote it didn?t seem like I was getting upsold and charged more than I needed to be compared to other companies. I highly recommend them to everyone and I will be hiring them again for any future project"

"He was very professional"

"They came out and replaced my broken 34 year old furnace in about 3 hours."

"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."

"They were excellent. Very prompt and professional. I definitely would highly recommend them."

"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."
