Big shoutout to Fletcher Plumbing & Heating owner and staff. The owner came to my home and provided…read morefantastic professional service; he fixed my heating system, took the time to explain what the issue was and they gave us a more than a fair price and came through in a time of need of a major crisis. I highly recommend their services! They are the Best Plumbing & Heating & AC company in the State of Delaware!

About 5 Years ago, Fletcher selected and installed a new central AC system for my home. There have…read morebeen numerous costly repairs since - even with a 10 year warranty (which does not cover much). Latest issue was a bad coil needing replacement - $1600+. I was required to pay a 50/% deposit the first week of September. It is now the first week of November and I still do not have the new part! There have been numerous excuses and unkept promises for status calls, most recently from Fletcher owner. BTW other smaller household plumbing issues have required return visits to properly resolve.

He noted on the invoice I was not happy with the system and stated he and the service manager would be back out the next week to check the system. As of 02/27/25 I have not been by contacted by anyone from this company. I have made multiple calls about this system and it is still not working correctly. To have this system put in was not cheap , and it is still costing money. I just want the system fixed so I can have proper heat in my home and an electric bill that is not almost $500.

TL;DR: they refused service to long-time clients because we had the audacity to ask for a measly…read more$200 off their HVAC bid. Clients of theirs for years, no complaints. When we needed a new HVAC, we got an estimate from Frederick that was $1000+ over the estimate from another long-time, reputable local company. But out of loyalty to Frederick, we politely asked if they would shave $200 off to come *slightly* closer to this other quote. We actually hate haggling, but had read that you're expected to, for new HVAC. Can't hurt, right? They responded. Had they just said, "No, that's not possible due to XYZ," we would have hired them and paid the full price. But instead the rep explained why it wasn't possible, and then, in a polite but insulted tone, *rescinded their bid*, essentially telling us they would not be doing the job either way. All over a request for $200 off a $7000 job. We were stunned. Needless to say, we haven't called them for anything since, and we're the kind of easy-going, non-complaining customers contractors usually like to have. We got our HVAC at the other place and it's running fine, a few years later. Owner, if you're reading this: I get that you're doing well enough that you don't need to accept anyone's attempt to haggle, and can charge a lot more than the competition. Good for you. I'm purposefully not giving you a 1 star because I don't believe in trying to hurt someone's business. But talk to your guys about not reacting in a personal way to long-time customers. The reaction we got was really uncalled for. Maybe the guy was having a bad day, but you have to leave that behind when you're interacting with a customer, especially an established one. He could have just said "No, we can't do that, but let me know if you want to proceed with us." We would have.

Josh and his crew have been my go to plumbers for about four years as of this review. Josh has…read morealways been courteous, responsive, patient and priced fairly. Thus far they have fixed multiple leaks (one of which they had to be called back for to fix), installed gas lines, and removed a tank water heater and replaced with a gas tankless system.

I will continue to support JDM#1 plumbing until I have a reason not to and I think anyone looking for a reliable tradesmen in the area should give them a try.

What a crook of a company. I scheduled an appointment for 9:00 AM, yet the technician showed up at…read more8:20 AM. At that exact time, I was getting ready to call and cancel because I had already troubleshooted the issue myself and confirmed my system was working normally, so the service was no longer needed. When I originally called, the only fee mentioned was a $120 diagnostic fee. There was no mention whatsoever of a no-show fee or a travel fee. Now they are trying to force me to pay a $59 travel fee, even though the technician arrived before the scheduled appointment time. To make matters worse, this fee was not explained to me until after they had already shown up. Completely unprofessional and misleading business practices.

They worked nearly the whole week at our house and it was a pleasure to have them here! They're super thorough. What little mess they did make, they cleaned up every day.

They also brainstormed with us about other attic issues and were able to tack some extra things onto the job. Lloyd called a parts manufacturer when I had questions about the type of bulb they used.
