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

"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."

"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."

"Excellent job! Very diligent, efficient, knowledgeable, customer service oriented. I'd hire Devon and Al again and recommend them highly to others."

"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 "

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

"Excellent! Hiring again and again . Best company and service."

"We had Evergreen Home Heating and Energy install a new water heater and furnace, and unfortunately, the quality of their work has been disappointing. Recently, I noticed several issues with the intake and exhaust pipes. Several hanger straps attached to the wall are broken, and one of the joints on the water heater exhaust pipe is leaking water. I suspect this leak is caused by the imbalance due to the broken hanger straps. I expected a professional and reliable installation from Evergreen Home Heating and Energy, but these problems indicate a lack of attention to detail and quality. Based on my experience, I cannot recommend Evergreen Home Heating and Energy. If you’re considering them for your home needs, be cautious and perhaps look elsewhere."

"In 2020 Eco Electric installed a Whole House Fan in our home. It has worked well for us and helps cool our home in the summer. Recently it stopped working. I called Eco and they sent Kyle out to diagnose our problem. Kyle was able to quickly isolate the problem to wiring in a recently installed smoke detector. He was able to fix the matter and get us back up and running. I do recommend Eco."
