“They're just incredibly professional. They're always on time, and they work their tails off. They're just as good as I've ever seen. They did heating, air conditioning, and plumbing work. They get an A; It was definitely excellent.”

“They've done quite a bit of work for us. They did a little electrical work, they did a little bit of plumbing with my hot water heater, and they installed a whole new heating and air conditioning unit. I'd give them an A+ overall. They did it expert, and they were easy to work with. They've been great. I've never had any problems with them. I have already recommended them to someone else.”

“I think it was great. The estimate and the initial consultation was great. They explained the options and picked good options. The work guys came on time and got the work done when they said. Also, they cleaned up after themselves, which was great. They even followed up with the inspectors, got that done. It's all good. We hired them for three things: they did a water heater for us, they did an HVAC system, and they did one of those units. It was a special case, a Mitsubishi ductless split system, very cool technology. They get an A.”

“They were just very thorough and answered a lot of questions. They were completely knowledgeable whereas the other organizations I was working with were not. They were doing heating, cleaning, and repair. They're excellent—A.”

“Everything they've done for me in the past has been excellent. They've done a lot of everything, including the hot water heater, and they've always done good work. I'm just waiting on them to come out tomorrow to fix an outside spigot that they repaired a year ago which started to leak again. I'm just going to have them cut it out, put a new one, and be done with it. I'd rate them excellent.”

“I got a completely new HVAC system and they installed a separate spit unit to replace a 30-year-old furnace and air conditioner. They were retailing a product which had really good reviews. They were on time. They were very careful, knowledgeable people, and they did really good work. I mean, everything worked right the first time. I'd give them an A+ overall. I was particularly impressed with how careful they did the installations and made sure everything was perfectly lined up with the split unit and everything else.”

“I liked that they were professional and did a good job. They worked on my air conditioning. They're A+.”

“I liked that they're reliable, they fixed what needs to be fixed, and they do good checkups. We have an ongoing contract for maintenance on our heating and air conditioning system. I would grade the overall experience A+. I would highly recommend them.”

“I liked the service, the labor they did, the willingness to come on time. They've done the checks of the furnace and the air conditioning. I think I've had them for about a year now. I'd grade them A+. Very good, friendly people. Highly likely to recommend them. If someone asked me, I would definitely tell them.”

“I liked they are consistent, friendly, and reliable. They did the spring cleaning of the air conditioning unit in our house. I'd rate them A+. I would highly recommend them. We've been dealing with them for 20 years, and I've never had a complaint.”

“I'll grade them A overall.”

“It seems like they knew what they were doing. I think they did a good job. They were looking at what's going on with the equipment, the HVAC unit, and then making sure it looked OK for the upcoming summer. I'd give them an A+. I would highly recommend them.”

“It was good. They were prompt, and they do what they say. It was regular maintenance. I'd give them an A+.”

“It's been a couple months, and I just like the service, that's all. They come on time, they do the job, and everything runs smoothly. That's for my HVAC unit. I would give them an A+ overall. I would recommend them if somebody needed to have that service.”

“It's covered in my rent, so I liked that I didn't have to do anything when they got the job done. They were turning on the heat in the fall I think. I'd give them an A+ overall.”

“M.E. Flow came, they did their job well, and we had no complaints at all. It was quick and easy. They checked our A/C unit to see what was wrong with it, and then they replaced those parts. They deserve an A+ overall.”

“M.E. Flow serviced the air conditioner. They are real good to deal with. I liked that they're friendly, and they know what they're doing. I would grade the overall experience A+. I would highly recommend them, and I already have recommended them.”

“The technicians were very knowledgeable, very professional. They were just pleasant to work with. They installed an air conditioner. I'd give them an A+.”

“They are competent. They basically do our HVAC stuff. I have been using them since 2000. I would grade the overall experience A+. I'd be extremely likely to recommend them.”

“They come and they check it out, you know, twice a year. They came, they did it, and everything seems fine. I've had different people come different years, and I think they've all been very nice, very helpful, very neat. The guy that came this time said that if I left my fan on all the time I wouldn't need as much air conditioning when I actually needed the air because it would be moving it around the house better. I've been doing that now, but since he's come, I haven't had another electricity bill, so I'm not sure how that's going to affect that. It has been comfortable in the house. They're an A+ overall. I would definitely recommend them.”

“They did HVAC work for me. We've used them for a few years. I would grade them A+.”

“They installed a whole unit for me a year ago. I think they're great because I had a problem, my son called them, and they came right away and fixed it, no problem. I'd give them an A+ overall. I would recommend them to anyone. In fact, I already have.”

“They replaced our A/C system. I liked that the sales guy was nice. All the workers were respectful and courteous when they came over. They were very clean and efficient. I'd give them an A+. I would very likely recommend them.”

“They seemed like they're well-qualified, and they seem to do a good job when they're doing it. They worked on an A/C and heating unit for me. I would grade them A+. I would highly recommend them.”

“They showed up on time, and they showed up early. They inspected my furnace and my heat pump, and they changed filters. They noticed—we just had our system installed a year and a half ago that they installed—that the supports that were holding up the condensers outside were broken, so they came back and fixed those for free, and it was very nice. They got it done, and it was nice. We'd used them before we installed the new system. They've done HVAC work for us. I'd give them an A+. The quality of the work and customer service was good. They came early, which was good.”

“They were dependable and did good work. They did air conditioning work, and it was an A+ overall.”

“They were prompt, and I think they waited for me because I was around the corner when they got there. They did a service check on the HVAC. I'd grade them A+ overall.”

“They're prompt, and they're good. They're conscientious. They do good work. They got good people working for them that deal with me, so we've had a very, very pleasant experience with them. I'd give them an A+ overall. I have recommended them several times to a number of people.”

“I liked that they have always been proactive in terms of identifying issues that may be emerging and alerting us to it so we have a choice as to whether we should take preventive action or wait for a while. We have been using them for decades, literally 20 or 30 years now. They worked on A/C unit and plumbing. I would grade the overall experience A+. I would highly recommend them.”

“Everything was fine as far as I remember. It was just a check up on the heater, I believe. I'd give them an A.”

“I guess the guy seemed knowledgeable and good customer service. I was just having an indoor humidifier installed. They get an A.”

“I liked that they were friendly, came when they were supposed to, and fixed our air conditioner. They get an A. I would highly recommend them.”

“I liked that they were quick to solve our problem the first time. The second time, I think, they were here and just did a tune-up on the system, and that worked fine, so we haven't really had any issues. They are quick, and the guys were nice too. They replaced the air conditioning unit. It worked fine, and it's working like a champion during the hot days. I would rate them A. I would highly recommend them.”

“I liked that they were thorough, and they did a good service on our air conditioning and HVAC. I would grade them A. I would likely recommend them.”

“I think their presentation and I think the way they handled the matter was reliable. Their service was air conditioning, so we had a technician come out and diagnose the problem. Everything is working up to expectations now. I would give them an A overall.”

“I'd give them an A overall. I don't remember any issues, so I'm sure the customer service and cleanliness were fine.”

“It's just a regular maintenance contract inspection and service. It's on my air conditioning unit. They've had good communication. They've also been accurate and timely. They provide sound advice, not trying to gouge you out-of-pocket for stuff. I'd give them an A.”

“I've been with them for quite some time. I have scheduled maintenance come in the fall to do the heating, and then they come in the spring and do the air conditioner. They're on time and done properly. I would grade the overall experience A. I would extremely likely recommend them, and I've recommended them to several friends.”

“I've had a good experience with M.E. Flow for 20 years or more. They have installed and maintained my HVAC system. I would grade the overall experience A.”

“I've had a long-term contract with them for HVAC service, so they're fine. I'd give them an A.”

“I've had them under contract for eight years for heating and air conditioning. They take care of the system. They get an A.”

“Just a routine check to make sure everything was functioning properly A/C wise and stuff. It was the same gentleman to come out about three times within the last couple of years for, you know, winter and summer, and they always check out good with him. Everything is working up to expectations. I'd grade them A.”

“M.E. Flow got the job done. Their customer service was, you know, as expected. It took a little longer to get the part. That wasn't anything anyone had any control over, but otherwise it was fine. Our last visit had nothing to do with A/C. The A/C is fine. I'd give them an A overall. We don't talk to that many people, but if someone asks, we'll recommend them.”

“Nothing in particular that I liked. We got a new unit with them. I think it was an A overall.”

“They diagnosed pretty quickly what the issue was and took care of it. Last year it was on a rental unit, an apartment, and they had to put in a new heat pump. This was the first time I'd used them because they were recommended to me because the company that first went out there and diagnosed the problem—that sort of service—they recommended M.E. Flow. I would give them an A. You know, I wasn't there when they did the work. Under the same circumstances I'd recommend them if a neighbor or somebody needed the same sort of work.”

“They did air conditioning and heating work for me. I'd give them an A.”

“They did air conditioning and heating work. They get an A.”

“They did the A/C and heating check. I liked that they are knowledgeable techs. They are very helpful and would always suggest things to be done to the system to improve it. I'll rate them A. I would highly recommend them to friends and colleagues.”

“They got our air conditioning working. So far, it's working fine. Other than the scheduling, the customer service was fine. They couldn't immediately fit us into the schedule, but they came as soon as they could. I would grade the overall experience A.”

“They had very good follow-up, very good service, especially when we ran into some issues. They installed a new A/C. Everything is working very well. There were a couple of issues. There was one personnel issue that they had to take care of, and another issue where they had sized a couple of things incorrectly and needed to break the news to me that they couldn't install when they had promised to. They get an A.”

“They helped us with our air conditioning. They were quick getting here, they were really nice, and he explained everything they did. They get an A.”

“They installed my HVAC unit about a year and a half ago. They've been doing the half-yearly checkups, and we've been pleased. They seem well organized and professional and show up when they say they will, and so far, all seems well. They're an A. I would very likely recommend them.”

“They were great. They are always timely, and the servicemen were generally nice. They were servicing our air conditioning. We've used them off and on for about two years. They get an A.”

“They were just very reliable, very pleasant, and they knew what to do. They've worked on our heating and air conditioning systems and diagnosed something, they were correct, and they fixed it. They showed up when they said they would. I'd give them an A overall. Nothing was lacking. We've been using them for a very long time, so that should say something about the quality of what they do.”

“They worked on the HVAC unit for me. I'd rate them A. I would highly recommend them.”

“They're just really pleasant guys. They were replacing the A/C and heating unit. I'd give them an A overall.”

“We're 100 percent satisfied.”

“We've had them for several years, they're always timely, they do good work, they're clean, and they're professional. I'd give them an A overall.”

“When they came out they were professional and fixed the problem. They worked on a HVAC unit for me. I would grade them A. The only downside is that it took a while to actually get them out. I would very likely recommend them.”

“I liked that they came when they said they were going to, and they did the work that we asked them to do. They've done quite a few things. They fixed our water heater, they came to check our air conditioning unit, and they've done maintenance on my father-in-law's heating system. I would grade the overall experience A. I would very likely recommend them.”

“I liked that they come very quickly, and they always do a good job. I've never had any problems with them. They worked on my A/C and heating unit. They have also done private plumbing work for me too, and everything has always been very good. I would grade them A.”

“It was a very positive experience. I liked the availability, and the professional work of the people that have come out. They're very knowledgeable. When they said they were going to be here they were here in a timely fashion. They did the job right the first time. It was a good experience with them. They did HVAC work and then plumbing. I would give them an A.”

“It's been working. They put a new furnace in. This isn't the first time I've used them. They've done plumbing work too. I'd give them an A overall.”

“They did two things—a plumbing inspection, and they did my HVAC inspection for the summer months. There wasn't any trouble. The workers are always friendly and informative. I like that they always smile. I'd grade them A. It's likely that I'd recommend them.”

“They put something in my air conditioner, I think. I liked that they were prompt, and they did what they said they would do. I have no issues with either. They put in my water heater and my air conditioner. I would grade the overall experience A. No complaints about it whatsoever. I would highly recommend M.E. Flow.”

“They were thorough, and they explained everything. They've done a few different things. They've done both heating and air conditioning as well as plumbing—just repairs. I'll give them an A overall.”

“I know what to expect, they are courteous, they are good. They do a good job. They take care of my annual maintenance for heating and air conditioning. I've used them for the last three years. I would grade the overall experience A-. I would likely recommend them.”

“There was nothing in particular that I liked and disliked. They were just doing work on the A/C and heating unit. I'd give them an A- overall.”

“I liked that they did what they advertised they would, so the product seems acceptable. They did the job I expected them to do, and I was happy. They replaced my water heater. Technically, it's the first time I've used the water company, but they fixed my furnace because it was stuck. When we went down to fix the furnace we eventually discovered the water heater was leaking, so they eventually fixed that too. They get an A-.”

“They serviced our air and heating unit. They're always on time; they come when they say they're going to come. They don't oversell me on anything, and they've been an honest company so far. I'll give them an A+. They're excellent.”

“The M.E. Flow technician came to my home to inspect my gas heaters and to take care of a problem. The technician did a fantastic job. He quickly discovered the cause and fixed it on the spot. In addition to being very knowledgeable and technically competent, he was also very considerate and a great conversationalist. I highly recommend M.E. Flow—A+.”

“Outstanding—he took time to answer questions and do a thorough check. He was very knowledgeable and made some adjustments that no one else had thought of, and the furnace is working the best it ever has.”

“I have used M.E. Flow for HVAC services since about 1977. They have been unfailingly expert and reliable—A+.”

“The tech was highly knowledgeable and intent on providing the best solution. I couldn't have asked for a better experience.”

“Technician Fabian is knowledgeable, thorough and friendly. M.E. Flow has been my HVAC provider for thirty-plus years.”

“Technicians were very efficient in servicing our heating and air conditioning units. Gave us important points on how to keep our unit in good working condition.”

“Have used for years. Satisfied. I have a contract with them, which helps to make sure I get service when needed.”

“New/replacement install in July 2015. First rate on equipment and installation. We had a tight spot to put the new air handler in, but the installers figured it out. The first digital thermostat wasn't working properly, and the original technician that installed it really didn't know what he was doing. I asked for someone else to come out to fix it, and he was right on target. Recognized it was a faulty thermostat. We had a new one in just a few days. With the HVAC install, we were supposed to have a one-year maintenance agreement. That never got set up. When I realized this and contacted M.E. Flow about 10 months later, they fixed it and set us up for the following year as a replacement. Overall, we are very happy so far.”

“They double-checked everything they did, and they had some considerable expertise. They had supervisors check the work and make sure it was correct. They installed a heat pump and repaired another heat pump. I chose them because they sounded good. I had an interview with them, and they made an offer. I would give them an A.”

“I know we've been pleased. They've been professional, and they've done a very nice job so far. We like the customer service. We haven't had any issues with their work. They've done some maintenance work. They actually replaced one of our systems, they've done a couple of checkups, and they've done maintenance. It was all HVAC work.”

“They know what they're doing. The job was an HVAC check, and they made sure that the HVAC system is working to specification. They're friendly people. They come in here twice a year, and they do the work quickly and efficiently. They're out of here in no time. There's a contract in this building with them. They're an A+.”

“The service was very good, and the people are very nice, so I like it. Everything was very good. I remember that everything was very smooth and very good. Over all, it's very good. They get an A+.”

“They're very good as far as I can tell. They're here on time, they work, and they're polite. Everything was really good, and I was pleased. They had to do an inspection of the heating and cooling systems. They had to come back and put in a tray to catch water in case something leaked and flooded. There was some other little part they had to do, and they showed it to me. They were recommended to me by a friend of mine. I lived here before and had used them, but then I moved to Colorado, so when I came back, I just called them again. So far, from what I saw, it was A-grade work. I was certainly pleased. I'd give an A grade for the person that came to inspect. He explained things to me that I didn't understand exactly, but it sounded good.”

“They got everything installed in the first day, they left the place very clean, and things are operational. They did HVAC work and put a new hot water tank in. I would recommend them. They've done work for me over the past 30 years.”

“They get here on time. They've just always done a good job for us. They did air conditioning. They did maintenance on two units. They installed them for me as well. I've used them for 20 years. They get an A grade from me.”

“They're on time, they do good work, and if I need them to come back, they come back. They clean up after they're finished, so I like their work. They put in an air conditioning and heating system. I found them in the Best Pick Reports. I would recommend them. It's an A-grade company.”

“I just had them do one service call so far; it was just preventative maintenance. They were on time and professional, and they did what they were supposed to do. They did some preventative maintenance; that was the service agreement I set up with them. It was for HVAC work. I'd give them an A.”

“They were efficient and on time. Everything was fine. They just did maintenance for the HVAC. The customer service was fine. I am happy with the service. I chose them because of a recommendation from a neighbor. I'd rate them as an A. I told them I would call them again.”

“It was a father and son who came in. The father knew the business. The son was going to a trade school and was also learning this business. The son did most all the talking, but they were very cordial and very pleasant, and they showed me everything. They were just nice all the way around, they didn't leave a mess, and they looked like they knew what they were doing. I was here with them in the same room from seven o'clock in the morning until they left here, just about three o'clock in the afternoon. I've got nothing but good things to say about them. They put in a brand-new furnace for me.”

“I like it. They are very nice. Their guy who came for installation was very cooperative. They asked me everything, and they did a good job. I would recommend them. I would give them an A.”

“I had interaction with them before, so I knew a lot about them. We used them at the company I worked at, so I just trust them. My heater went off overnight, so I called them to come out and check it. They found out that the igniter went bad. It was great. I just called in, and they had no problem answering the questions and getting somebody lined up for me. They're an A-grade company.”

“They did a good job. They were very knowledgeable. We had a whole-house humidifier installed. I'd rate the company as an A.”

“They met their obligation on the cost estimate and the schedule of the installation for the furnace and air conditioner I had put in. They stayed until the work was complete and checked everything out to make sure it was functioning properly. I've had past experiences with them before, buying parts and having some minor service over the years, so I was familiar with them. I would recommend them and give them an A.”

“I was thoroughly impressed with M.E. Flow. It was our first time using them, and we loved them. The serviceman was very nice, very knowledgeable, and respectful. He explained how our system worked and how to properly maintain it, and I felt that he was very honest and informative. He checked everything out for the summer and got the system all geared up. They get an A+.”

“M.E. Flow was awesome. There weren't any surprises; it was an all-around good experience. We needed some new parts for the fan in the air conditioner, and they took care of everything. They definitely earned an A grade.”

“I liked their overall appearance, from the cleanliness of the vehicles they showed up in to the uniforms the guys were wearing. They were very informative throughout the process. From beginning to end, it was a positive experience. I'd give them an A+.”
