Get matched with top water heater installers and replacers in Frederick, MD

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"Replaced air conditioning unit. Super nice brought us portable a/c units until installation was completed. Very professional and easy to deal with."

"This is the 2nd or 3rd time that we used Jimmy and couldn't have been more pleased. My house felt like a sauna and we were desperate for Jimmy to come over. He was extremely busy however he found time to stop by. We were told that we needed a new unit and by 3:30 the following day, we had a new unit installed. Can't get better service than that!!!"

"We received same-day service. Our serviceman, Fred, did a great job. He was very professional and solved our water heater problem."

"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."

"I called at 8:00pm on a Tuesday night. The plumber came before 10:00pm as promised. He replaced a leaking shut-off valve and associated pipe within an hour. Cost was as quoted for one hour labor plus parts which were less expensive than expected. No extra costs for travel time or anything else. We will definitely use again."

"This was a last second thing. Our hot water heater died on us. Left him a message on Tuesday afternoon. He showed up first thing next morning. Right on time. Discussed the job and he gave me a estimate with a small window. And he said he could have me back with hot water in a few hours. Sure enough less then 3 hours later I’m back running. Very good and clean job. Very professional with all aspects of the job which was nice. Best part of it all when it’s time to pay his his price was barely over the low end of his estimate. Everyone else would most likely been barely under the top end of their estimate. So a very good clean job done as a rush for a good price."

"Great! I have used Furr Plumbing many times so I was not surprised that they quickly located and fixed the problem however I was surprised when I received a NO CHARGE INVOICE! Thank you Furr Plumbing!"

"Easy to communicate with, very efficient, timely, and the most affordable for great work and quality items. Rob installed and removed a water heater, replaced two faucets, and replaced rusted bolts and handle on the two toilets. Will be keeping Rob as a trusted plumber for any future jobs."

"Family Fire Service did a great job replacing my water heater! They were quick, attentive, and thorough. Excellent work! "
