A selection of 114 homeowner reviews:
“They replaced a thermostat on the heat pump system. The workers showed up on time. They properly diagnosed the problem, and they installed the correct replacement part that fixed it. If A is the highest, then I'd give them an A.”
“I had some work done on my air conditioning. They had to go up in my ceiling. They did what they had to do and left.”
“They've put in one of my systems and then they replaced it so it's over the years. They seem to know what they're doing. They do the servicing for me, and it doesn't break down so that's always a good sign. I would give them an A. I just signed another contract with them to do my servicing so I just really like them. They just do their job and it works.”
“They're actually my heating and air conditioning company. The guys were very professional. That's why I actually use them all the time. They're clean, they're professional, and they do what they're supposed to do. I'd give them an A.”
“They maintain my air conditioner and furnace. They have also replaced parts for my furnace. They give good advice, they're always professional, and they're on time. I'd give them an A.”
“They did routine maintenance. They seemed to know what they were doing, and they took care of what they had to do. I'd give them an A.”
“They put an A/C and heater in. They did a checkup last year. Everything was fine. We'd give them an A.”
“They always fine-tuned our air conditioning and heaters twice a year, and we probably had them in both of our houses for maybe the last 12 years. They're on time. If we had the furnaces checked for the winter, they never failed; if we had the air conditioning checked for the summer, they also never failed. They do what they say they're going to do. I would say they're an A, at least.”
“We have an annual service contract with ServiceMark. They showed up when they said they would, and they did the work in a timely fashion. I'd give them an A.”
“They serviced our heater. He was on time. I'd give them an A.”
