Get matched with top tankless water heater repair pros in Unionville, MD

"I had just purchased a townhome with 4 bathrooms and they are all the original toilets from the year it was built, 1993. Every unit was operating fine to my knowledge except for one that would keep running. Shane came right at 8am and in about 35 minutes went to every toilet, tested it for any possible leaks, and noticed that the water level adjuster was not set right. I mentioned to him that the flush on every toilet seemed very "weak" and that was right away what he looked at and showed me, that the water level was set too low, so the tank was not filling to the proper level to give the right amount of a "flush."
Shane also took the time to show me a very easy fix on the toilet that I was complaining about running, and it was that the chain was getting stuck in the flapper valve, so that was a simple fix. What I respected and appreciated the most from Shane was his professionalism, and his willingness to show and explain to me everything he was doing so I could learn myself. A true professional and he was very honest about how much he takes pride in his work (and it shows!).
Thank you very much Mahon Plumbing and Shane, and once again Angies List for providing me another great experience/referral. I will also say that the rep I spoke to over the phone handling my initial call was extremely nice as well, not your typical secretary that takes a name and number. Was very nice and professional as well.
So for $105 and about 35 minutes of work, I got four toilets tested which all came out OK, and "fixed" for the weak flush issue, and a little bit of plumbing 101!

"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

"Our water heater died, and was leaking. We called after hours, and owner answered the phone. Technician came out next day, and he showed up on time and replaced the heater. Plumber was very courteous, professional, and helpful with advice. No complaints - work is guaranteed. Only downside: price for the water heater itself was high - could have bought comparable unit much cheaper at HD or Sears, but would then have needed to have it delivered and installed by the plumber anyway. Their work is was very good, which was most important and we would definitely use them again."

"When I bought my combo tankless boiler/hot water heater, the original installers messed up installation, then couldn't figure out how to fix it. Thank god I found Rod. He fixed their mess, installed a sediment filter that's been super effective, and recently helped fix a venting issue caused during a remodel. He knows his stuff inside out, is fast and efficient, and a real pleasure to work with. Would absolutely recommend him for anyone with on-demand water systems."

"Darren, the Salesman, was extremely knowledgeable and helpful. Very low pressure sale tactics, but laid out all of the options for you. The crew came and finished installing a new heat pump and heat exchanger in a half day and then another individual returned the next day to install a new water heater. Great communication and attention to detail every step of the way! Would highly recommend!"

"They installed a whole house water filtration system. They are professional and efficient. They are my No 1 plumbers right now. Michael and Sons were the first to call but did not show up. They are unreliable. If you want a reliable company that will get the job done efficiently, Art's plumbing is the one."

"The audit went well.  The follow-on work (water heater replacement, heat pump replacement, and caulking).
They did a pretty good job.  They did sub out the water heater and heat pump parts.  The new water heater had a heat pump unit on it too.  The water heater had an alarm that went out and was eventually replaced.
The subs did test my patience when they started late and ended even later than they said they would.  I eventually told them they had to get out at a certain time.
I took a year to write this because I wanted to back it up with cost savings info.  Unfortunately, the jury is still out on whether or not the system is paying for itself.
