A selection of 114 homeowner reviews:
“ServiceMark does a wonderful job. They installed a hot water heater, and they worked on our heating system. They've done a lot for us, and we're very pleased with them. They know what they're doing. They're clean and attentive. They get back to you. It's a solid organization, and I trust their opinion. They're A+.”
“They serviced our heater. The technician was very pleasant. He came on time and did his job. Everything was fine. I would say it was A+ work.”
“It was great. They always clean my air conditioning and service my furnace. They're very, very pleasant and personable. They do good work. I'd give them an A.”
“They replaced a thermostat on the heat pump system. The workers showed up on time, properly diagnosed the problem, and installed the correct replacement part. I'd give them an A.”
“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.”
“They got the job done properly, and that was the best thing. Everything was fine.”
“They did a good job. I've been with them for over 20 years. I'm happy with them. They're very professional, they do their job, and I never had problems. They come and do service checks. We have a contract with them. We have not had to call them back. I have a little problem, I called them, and they were supposed to get back to me about the issue, but they never called me. As far as work, it's excellent, an A.”
“This was a very long time ago?. They serviced the heater, and I was perfectly happy. I've used ServiceMark for a very long time, and we are perfectly happy with them. There are so many people out there—if I weren't happy, I wouldn't use them. I would grade them an A.”
“It was great. They did a good service for me, and I thought everything was fine. I have all of that with them, heating and air conditioning maintenance. One of my best friends knows one of the salesmen—that's how I found out about them. I would grade them an A.”
“Their customer service has always been great quality. I can't complain, because when they leave, everything still works. I've been with them for many years, so I'm pretty pleased. Our water heater is through them. My parents were customers of ServiceMark for several years. They do my heating and air conditioning, too. I would grade them as an A. The only thing is that maybe last year or the year before one of the service men came out, he gave us the air filters for about six months, he said it was part of the deal, and the last few guys said that's not true. I didn't know if that was. It was wonderful that he had them. It's pretty great because our air filter is pretty hard to find.”
“It's been a while since they were here. They did maintenance the last time they were here. We would recommend them. We've used them for a long time. I would grade them an A+.”
“They did maintenance. I chose them because I've used them before. I would give them an A+. They're very good.”
“They perform the service that we ask for in a timely fashion, they do heating and cooling. The builder used the company that turned into ServiceMark, so we inherited them. I would grade them an A.”
“They were very good.”
“They are usually very efficient, and the guys who show up are always very courteous. They communicate what's wrong or if I have a problem. They are very cooperative and get the job done. They don't take too long—all of those things are good things. It's been maintenance, but if it breaks down, they also come out and repair. I would grade them an A.”
“I just like that they did what they said they were going to do. It was remediation after a burst pipe, and they got it done in a timely manner. I would grade them an A.”
“I would grade them an A—they do heating and air work for me.”
“They were professional, they were here in the time frame that they said they would be coming, and they did the job that they were supposed to do, which was a maintenance situation. It was our heater. We have a service contract with them and have worked with them for several years. Everything has always been cool. I would grade them an A.”
“They were prompt, on time, and we got it done in a hurry. It's one of those things I have where I pay for it, and they come around every fall and check the heater and all of that, like a checkup. I've been a customer for years. I would grade them an A. Everything was fine.”
“They timely and efficient, I will say that. It's heating and air maintenance, and if anything goes wrong, they fix it. We have a contract with them. I would grade them an A.”
“Everything's working fine.”
“We are satisfied.”
“They know what they are doing and are very professional. They put in a propane range and then changed out a tank with a more extensive regulator so that I would get a more even flow. I had them back for my sump pump. I haven't had to have them return for any reason. I would grade them an A.”
“Everything was fine. We've had them for 20-plus years. It was maintenance work. I haven't had to call them back. I would recommend them to family or friends. I would grade them an A.”
“They were on time, and they did what they said they would do. They just did HVAC for me. I've been using them for a while. The customer service was pretty good. I would give them an A.”
“They just did HVAC work for me. The customer service was pretty good. I would say they're an A, I guess.”
“My house is 20 years old so I've been using them for 20 years. I guess that says more than anything. I have a service contract with them for the HVAC. I would say they're very nice and very accommodating. I would give them an A.”
“They're prompt. They come and fix your heat—they do my HVAC system and hot water heater. It's usually the HVAC. They were originally a local company I think who installed our system years ago. When they were bought out, we just went with the same company. The customer service was good. I guess I would say they're great; like an A. I've never had an issue, and they've always been prompt.”
“There was nothing that stood out. They check my HVAC. I chose them because they sold it to me. I would say the customer service is OK and that they're an A.”
“I liked that they got me heat. We have our contract with them. I would give them an A.”
“They were very punctual. They gave me a call like they said. They did good work, and I'm very satisfied. They do a tune-up on my furnace. The previous owner had a contract with them so I just kept them. I would give them an A. I have no problems with them.”
“I've been with them for a couple of years. I was truly satisfied with everything.”
“I liked the guy that they sent. He seemed very straightforward and honest, and he did a good job. I like them. They usually worked on my heating system. They did the original installation of our heating system when we upgraded to gas several years ago, so we've been with them ever since. I would give them an A.”
“They showed up the same day that I called, and the guy that came was very knowledgeable and did a good job. He took care of the problem. They usually come out and maintain my HVAC system. I have a service contract with them. They did the initial installation in 2004. It came with like a five-year warranty, and then I ended up with a service plan, so I just stayed with them. There was no reason to change. I would say they're an A.”
“They did do some work for me. Everyone was great, even when we had a little problem. After the initial service was done, they came out the next day to take care of it. It was great. It was good customer service. They actually did a maintenance check, realized that we needed a new furnace, and then installed the furnace for us. I would give them an A.”
“I've used them for years. I think they're reliable. They usually come out and do a maintenance HVAC check. I think the customer service is very efficient. There are no issues. I would give them an A.”
“There was nothing that stood out to me. This was for my HVAC system. The customer service was great. I would just give them an A.”
“I'm very happy with them. I've been using them for a number of years. I have them for heating and plumbing. We chose them just because of the acquisitions. I think the company eventually became ServiceMark. We've just been with the same group of people for quite a while. I would give them an A.”
“Everything was fine.”
“They just did my routine maintenance. I would give them an A rating.”
“I like everything about ServiceMark. I've only used them twice. Once, they came out for a repair, and once, they came out for routine service for my HVAC system. I used them because my brother-in-law recommended them. He has used them for years. I would say they're excellent. They also did a new installation for me.”
