The people who came out were rude and nasty. Not only that but they left messes all over. Called about it the next day. Had to wait for calls back all over. Claimed the were not qualified to clean up the messes they left. That's not the only thing they were not qualified for considering we had to reach out to other people. Who have all agreed they were in the wrong. Don't waste your time and money on this company.

ME Flow did a great job installing new HVAC. My house had a 20 year old AC that needed to be replaced before the summer starts to heat. Installation was clean and looks great. Very professional and communicative. Services: Install thermostat, Install AC, Heating system installation

Alex and Michael are superb ambassadors of professionalism for ME Flow. They are extremely experienced. They were very conscientious about respecting personal boundaries. They did not try to rip us off; to the contrary, they did everything possible to minimize our expense. Our five mini splits were covered by the ME flow service warranty. We think a midnight thunder storm caused the system to trip. Alex reset the system and also did the scheduled maintenance while he was there.

The warranty contract calls for two on-site calls annually and this was the first. Because I called this in as a "restore service" call, I was charged for that type of service which is an additional charge, even though the system is tripped as part of the system check. I am waiting to see how this is resolved. Other than that, I have been served by ME Flow for over 20 years, and am extremely satisfied with their work.

Amazing experience with M.E. Flow. They are fast, very knowledgeable and clean. They were able to acknowledge what was wrong, explain to us the problem and how they were going to fix it. They also explained the cost, offered payment plans and told us about possible cupons. They kept my husband and I informed about how everything was going to go and they did it fast. We are really happy with the service and the professionalism of their agents! We recommend this company!
