Get matched with top tankless water heater repair pros in Cavetown, 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."

"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."
