Great Professional Service
Great professional service. Always responsive and friendly technicians and sales reps. Highly recommend!
John Lanzetta
Allen was very pleasant and professional
Tech was very helpful in pointing out things to consider, if not now, sometime in the near future. I was given items to consider and a detailed reason for each item. Allen was very pleasant and professional. This was a free inspection when I joined their special home program. There are many program benefits, and for just $20 a month, too good to pass up.

Walter from M.E. Flow was great
Walter from M.E. Flow was great. Not only is he going to fix my hot water problem, he explained the parts of the hot water heater and what went wrong. I feel good now to spend money on the fix. Give Walter a round of applause. Ann Ryan

An excellent representative of M.E. Flow
Vic Cecci arrived at my property on Friday, 25 April, right on time. He performed comprehensive maintenance on my HVAC system and found a few issues that needed correction. He made the corrections and provided recommendations to improve my system. Vic was at all times professional, very thorough, and courteous of my time. He's an excellent representative of M.E. Flow. I look forward to Vic's next visit.

Paul Casagrande
Excellent Service
Excellent service are the two words to sum it all up about M. E. Flow. They have been very professional and responsive. Once I submit a request for repair, they will get back to me asking for availability. Once I tell them my availability, they send a technician. I get a text with the technician’s name and photo so that I know who to expect and confidently open the door. The technician gives me a call within the hour of arrival as a heads up. They order parts if needed and schedule a follow-up after the parts arrive. I am part of the comfort club which gives me peace of mind that when something does not work, I know that I can depend on M. E. Flow.

Very pleased with timely AC repair
My AC unit stopped working. The AC was not putting out cooling air. M.E. Flow sent a technician who quickly diagnosed the problem, and fortunately he had the part (transformer). They installed the AC fourteen years ago, and this was my first repair. The technician was very competent and courteous. I am very pleased with their timely response and work.

M.E. Flow Is My Go-To Provider Now
M.E. Flow is my go-to provider now. We just relocated to the area and had to have our A/C serviced. I called them Tuesday morning around 8, and around 12 their tech was here and determined the issue.

Everything You Need to Know
  • What is leak detection?
    Leak detection is the process of identifying and locating leaks in plumbing systems. It involves using specialized equipment and techniques to pinpoint the source of a leak, helping to prevent further water damage and reduce repair costs.
  • Are leak detection services expensive?
    The cost of leak detection can vary depending on the tools and techniques required, as well as the complexity of the issue. However, early detection can save money by preventing more extensive damage.
  • Can I detect leaks myself?
    While you can check for obvious signs of leaks, such as visible water damage or increased water bills, professional plumbers have the tools and expertise needed for accurate leak detection, especially for hidden leaks.
  • Is leak detection covered by insurance?
    Whether leak detection is covered by insurance depends on your policy. Some homeowner's insurance policies cover leak-related damages, but it's best to check with your insurance provider for specific coverage details.
