A selection of 700+ homeowner reviews:
“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+.”
“They did quite a bit of work for me, and it went fine. They ended up having to replace our entire furnace. I think everyone else in our neighborhood had theirs replaced about five or six years earlier, so I knew it was coming. I was happy with their work. I know a little bit about that kind of work and I thought they did fine. They did well. I'd say they were excellent, because I have no complaints. We had a tight fit in one area, and they had to go through some bushes, because the compressor barely fit. They navigated that well, though. It was all good.”
“M.E. Flow takes care of all our heating and cooling needs. We have a service contract with them, so I would give them an A+ rating.”
“M.E. Flow fixed a furnace problem for me. The work was quite acceptable. It has held up nicely so far, and they were upfront about the potential life of the repair. I'd give them an A rating. They were called to assess a problem that had actually been diagnosed by someone else, but I didn't care for the other company's solution. They gave me an adequate solution and the pros and cons of it, and then, they came out and fixed the problem. They appeared to be pretty straightforward. They were also very pleasant to work with.”
“We've used M.E. Flow for heating and air. They have been good. We have been using them for about two years. I'd give them an A.”
“They were honest about when they would come and what they would do. They guy was pretty courteous and helpful. It was good—I was happy with the service. They replaced the heating and air conditioning sensor. They didn't need to do the A/C until spring, so they turned the breaker switch off. I was having a problem with my thermostat, so they kind of reset it and stuff. They came out and assisted me with the thermostat. They got it going, and they earned an A.”
“The work was fine. I think I called them once with a question, and that question got answered. I think I chose them because of the advice somebody gave me. I had someone come out to see if the previous system could be repaired or not. They thought it could and advised me to go with M.E. Flow. We used them, and it worked. I would give them an A, because it worked. There was a second thing I called them about, too—for the filters, and I got a good answer. It's clearly working, and there have been no problems.”
“Everything went fine. M.E. Flow is a good company, and they did a great job. They installed a furnace and air conditioner for me. I've been with them for years. The one I had was bad, so they just put in a new one. I would give them an A grade.”
“I came home from out of town, and my furnace was dead. It was all old—the furnace, the air conditioner, and the water heater. I'd give them an A because they were good.”
“Everything went great. They replaced an air conditioning unit. It's been 10 or 15 years, but I would rate them as an A.”
“They're a very good company. We had a new air conditioner put in a year ago, and they come and check on the furnace. I'd give them an A.”
“Everything went fine—there were no problems. They did a maintenance check on the furnace and air conditioning unit. I would give them an A.”
“We had the whole heating and air conditioning replaced, and it seems to be working now.”
“Overall, M.E. Flow was good. They replaced my air conditioner and my heater, and I would give them an A.”
“They fixed the air conditioning, and everything went fine. M.E. Flow gets an A.”
“They are very responsive, and they have great communication. They thoroughly cleaned the problem and the solution. They are fully transparent in their pricing, too. I have used them a lot over the last five or six years. They've done a lot of HVAC work for me—the air conditioner, ventilations, repairs, and programming the thermostat—and I've had them do some plumbing work, as well. The last time they were here was for an air conditioning service. It was general maintenance—I have a contract with them. I found them through a referral from a friend. They clean up well after their services, and I find them to be respectful of my home. I would definitely give them an A.”
“We have a policy to have our air conditioning and furnace checked every year. A long time ago, we had to have a furnace put in. We had a water heater put in a few months ago, and I would say they did excellent work. There was a time, though, when our furnace went off, and they sent a couple of fellows who didn't get it checked right. They finally sent out one gentleman who stayed all day and took everything apart, and he found the problem. I'd have to say they do good work.”
“M.E. Flow has been very awesome. They are always reliable; they always come through when they say they will. Their technicians always seem to be fully aware of what issues we could be having with the systems. They're well trained and friendly. I definitely would recommend them—they're an A+.”
“We started doing business with M.E. Flow 20 years ago. They put in a heat pump for us. We've been very pleased with their work. They deserve an A+. The workers are very professional, very courteous, and respectful of keeping things clean while going in and out of the house. I'd recommend them to anybody.”
“We used M.E. Flow for air conditioning work. They actually found out what really needed to be replaced. Another company basically wanted us to buy a whole new unit. It's been working fine the last two years. I'd give them an A+ grade.”
“They did an air conditioning and heating inspection for me. They're very reliable, and they do excellent work the first time. If you need to call them for an emergency, they're very responsive. I highly recommend them. They're the company to call—I got rid of the company that originally installed my system and had the warranty on it because of M.E. Flow. A+.”
“We always have a positive experience with them—they're really good guys, and they really work hard. They put in a heating and air conditioning unit, and I would absolutely recommend them. Given the number 10 being the highest, I'd give them a 10-plus. I would absolutely give them an A+.”
“I thought they had good service. I'm a real estate agent, so I recommend them. They've done new heating and air conditioning—we own several properties, and they've done several of them. The workers are excellent. I'd give them an A+.”
“M.E. Flow did some work for me in the past. They were on time, and they serviced my air conditioner and cleaned out the lines or something like that. As far as I can tell, it was high-quality work. I would recommend the company. They get an A+.”
“M.E. Flow installed an air conditioner for me. They did a good job, and I'm very satisfied. It's been running, so they did great. They're competent, knowledgeable, friendly, and hardworking, and they cleaned up after themselves. Also, their customer service was excellent. They're coming out to do a winterizing check very shortly. I would give them an A in this case because they did a fine job.”
