Get matched with top tankless water heater repair pros in Lake Hopatcong, NJ

"Garden State Water Heaters provided excellent service for maintaining my tankless water heater. Carmine and Michael were very professional and communicative regarding my project. I highly recommend them for all of your plumbing requirements."

"AJ Perri did a water heater check and found a serious issue I didnâ t know I had. It was fixed under warranty within a half a hour. Their plumber was pleasant and experienced."

"Despite numerous visits, they were NEVER able to get heat to all parts of the house after the installation of a new natural gas boiler in September. This boiler replaced an inefficient 30-year-old oil fired boiler, which had to be replaced as it could no longer be repaired. I had no idea how good that oil boiler was!! Specifically, the radiator in one room never gets hot enough long enough to heat that room, and other radiators were slow to heat up. Company said that the lack of insulation in part of the house was the cause for one room not getting heat; however, the old inefficient oil boiler was able to provide heat to this room and the rest of the house (& more quickly too). Even on a warm day, heat is not provided to this room, so I don’t this insulation is the real issue. They said oil provides a more intense heat, but if this were true, why would anyone make the switch? For $9000+ the boiler should heat the entire house and they even charged us an additional $700 to balance and replace steam vents, which had NO effect on the heating system, and we continue to have very little heat in that one bedroom (we are now using a space heater). I will now have to hire another company to have the boiler evaluated, as I believe it is under-sized for the house. Although everyone was very pleasant, I would NOT recommend hiring this company."

"These guts are my go to guys for all HVAC repairs. Rebuilt one of my heaters in an impossible crawl space. Great service & reasonable."

"They did a fantastic job, however I believe the labor cost was a little steep. And they should share the maintenance on the water heater with the customer."

"Had a gas leak in my mechanical room next to my boiler and hot water heater and M.L plumbing came and tested the lines and found the leak and fixed the leaking pipe.Thanks M.L plumbing for job well done and at a very reasonable price👍."

"Had a flood water heater broke. Call the doctor and came the next day. Promptly on time. Very knowledgeable. Were able to repair instead of replace water heater. Would use again."

"I have a great service by Overall Heating and cooling service. They work very hard, proffessional and tried their best to do the job. They are careful when analysing the machines before replacing. After they did well with water heater replacement, I also want to use their services to replace heat pump and AC. They never let me feel regret to choose them. Everything was done properly. I appreciate them. It is hard to find a good team that can do all heating cooling and plumbing proffesionally. As an engineer, I also did a lot of research before moving forward with this team. Their technology knowledge and capacity is amazing! I will recommend to my network about this team."
