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

"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."

"Trent was kind, professional, HONEST and respectful. I reached out and he messaged within the hour. After brief conversation on the phone he was able to fit me in for a free water testing and system inspection that same day. I mentioned a 3 stage water system upgrade and after the water test we found our water system was working well. He provided suggestions as alternative approaches to itchy skin we experienced. After we did our own research we agreed to have him install a UVC light with an additional filter for good measure. We called and he inspected on Tuesday and he was there with the install on Sunday that same week! Amazing. Talked us through the tests and results and provided us with informational pamphlets as well as transparency about his product vendor. Once the job was complete he tested the system and taught us about it and maintenance procedures. He was kind & patient. The pipe work install was well done and beautiful. He minded the space and existing plumbing."

"We ended up totally replacing our heating and air-conditioning unit and everything we have done in the house has been through ET Lawson and under a warranty plan through them. We wanted the same thing. Nothing against Michael & Son. He seemed very knowable."

"We purchased a house and adding a whole house water filter was on our list. Our local Orbit dealer performed a free water test and confirmed a that a lot of the junk we had read was in our city water was in fact there. Our previous house also had hard water and we saw firsthand what it did to our pipes and hot water tank. Plus we were tired of a filtered water pitcher taking up space in our refrigerator. Our sales person went over all of the features of the Puronics 7000 system and outlined the maintenance which simple and easy to understand. Installation took place about two weeks later and the guys were done in a day. About a year out and we're still very happy with the improved water quality and the system itself works great."

"The contractor did a quick but thorough job repairing each electrical outlet and provided advice on how to maintain them properly. The ring doorbell installation was quick and neat. The contractor wore a face mask at all times and we had a completely contact-less visit (including the bill payment - we were able to "sign" via our own devices). This company was a pleasure to work with."

"They were prompt in scheduling the job, and they performed the repairs very quickly too. Great work, good value, we would use them again."

"Very positive explanation what they think the prblume is what it would cost step by step to make repairs great job thanks."

"He was able to quickly diagnose that the water leak from the water heater was a result of a ruptured tank, resulting in the need to replace the entire water heater."
