Get matched with top tankless water heater repair pros in Fremont, NH

"Robert was very professional, discussed the water heater problem that I had. Took pictures of my water heater has currently installed and he was able to provide an accurate quote"

"Joe is an excetant professional contractor, he provided a very competitive quote for the replacement of a propane hot water heater. He was able to do the work the same day as he provided the quote. Work is clean neat and very professional looking. Would not hesitate to contact Joe again on any future heating and plumbing needs."

He had the relief valve and expansion tank in his truck and was able to install everything without issue. I would recommend hiring them for your plumbing needs!"

"Excellent communication from Keith; outstanding service from Roger. Professional, timely, and reasonably priced. They came in under estimate on my boiler repair and advised that a second bit of work that had previously been discussed was not going to be necessary. I will definitely use them again and highly recommend them!"

"I asked for a rep to come to give quotes for repair or replacement of my gas boiler. Before he came the old boiler failed, and Heritage was able to quickly install a new one so that we without heat and hot water for only a short time."

"Professional, friendly. Did the job and showed photos of the resulting flushed out debris from our on-demand water heater."

"Tyler was extremely helpful and accommodating and helped me on very short notice with 2 plumbing projects recently, even spending almost an entire Saturday working when a washing machine install ended up being more work than expected. He is professional and extremely reasonably priced. Will definitely recommend and use for all of my plumbing needs."

"Gil was very professional and he took a lot of pride in his work. He did not take any corner when faced with problems and he made sure everything was done correctly and to code. Gil gave a reasonable quote after inspecting our old system to replace with a new heat pump. Installation were delayed due to personal issues but when we really needed heating once the temperature were dropping, he made it his priority to finish it. During installation there were issues with the old duct work which made the work more difficult. He didn't upcharge us at all to fix it. We very much appreciated in working with him and would gladly repeat doing business."

"The gentlemen who sell the product were excellent.  Punctual and answered our numerous questions.  The installation was timely and the laborers were great.  That's where the good stuff stopped.  First of all, there were scuffs all over the ceilings and a hole in the sheetrock where they had dropped a tool in the attic.  Secondly, the installation of the ac grates was shotty at best.  We had to take one down and realized they were only screwed into the sheetrock no strapping or molly bolts.  The biggest issue however, is that we have been without heat on three occassions, had zones running continuously, and had no less than five service calls to them.  We are beyond frustrated after spending so much and are still working to rectify the issue

I have updated our review.  After the last service call, the problems with the furnace have been fixed.  I believe they are now working with a different installation company which should match with their customer service end of things (which as i said was always excellent) we are still waiting for them to come back this summer to complete a few odds and ends and as soon as that work is completed i will give a final review
