"100% satisfied with the company's promptness, service, and cost to replace a gas furnace. "

"Wow, these people were great! After seeing another company struggle to get two very old fas fireplaces to work, our property manager was directed by another fireplace repair place (who no longer services gas fireplaces) to call Lifetime. They sent Travis McKibben to our home, and he was fast, efficient, and most of all, he got the job done and done well. He really knows what he's doing, and is a really nice guy too. If you have to get service on a gas fireplace (especially an older model), or need HVAC work, I highly recommend this company and this technician."

"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"

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

"He was very professional"

"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."
