"If I could leave less than 1 star I would. Blue Flame markets themselves as a wholesome, family owned business, when in reality they're owned by American Residential Services (ARS), which is owned by the private equity company GI Partners. In the process of installing an AC unit, the technicians did not lay down a covering on our carpet, and got black grease all over it, which we still cannot get out. Then when they needed to install the thermostat, they punched numerous incorrect holes in our wallpapered walls. The whole hallway needed to be re-wall papered, and we cannot buy the type of wallpaper anymore. Mind you, this was in July, its now January and we're trying to have Blue Flame cover the costs, and they keep passing us off to a new person in the company. This is a typical private equity company move, where they hope you'll get frustrated and give up. We're now dealing with their insurance, who is lowballing us, and gave a burnt offering to repair one hole. Do not use them!"

"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!!!"

"I love working with SMART. Our contractor used them as a Sub and we liked them so much we've used them several times on our own outside of that. Highly recommend."

"went well, was on time, he did a good job"

"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 "

"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."
