A 35-year-old furnace whose maker is long out of business is the kind of job that shows up in Armor Plumbing & Heating Inc's history. Its Angi profile describes it as performing plumbing services in Exeter, NH, and it holds 4.9 stars from 24 ratings there. A 2015 customer said he got that furnace working, came right back when it went out the next day, and saved them from buying a new furnace by cobbling together a switch from another furnace. A 2012 customer said he cleaned the furnace, explained the results of his tests and gave advice on further maintenance service. A 2011 customer said he made an appointment for New Years day, was punctual, and took care of work the furnace needed. On the plumbing side, a 2012 customer said Jim Knight called back a few minutes after a Sunday-morning voicemail, pinpointed the source of a water leak at the dishwasher and repaired it in about 30 minutes, with an invoice of $94. A 2012 reviewer said no water was coming from the cold side of the washing machine valve, and he came up with a plan to thaw the pipe that worked; the total bill was $75. A 2015 customer said he shut off the pipes to stop the leaking and came back within the hour to install a new hot water heater. A 2017 customer who said they had known him for 20 years wrote that he came over at 8:30 at night and came back the next day with more parts to fix the issue permanently. A 2013 customer said that while de-winterizing the house, the supply valve to the washer/dryer connections was left open, causing a minor flood in the bathroom, and Jim immediately blamed the customer for leaving the valve open. That customer said he was ready to cut a hole in the wall in search of the leak until the customer suggested turning the well pump back on; there was no leak.
I have known him for years and years. He is great. His name is Jim Knight. He is absolutely terrific. I didn't know how to shut the water off. He told me what to do. He came over at 8:30 at night. He fixed it enough to come back the next day with the part. He came back the next day with more parts to fix the issue permanently. He did get me through the night temporarily. He has bailed me out of a few small catastrophes. He installed the part and was done within 40 minutes. He doesn't make you wait 2-3 days to show up again. I have known him for 20 years. The service is excellent. If for some reason he fixes something and it ends up not being fixed within a week, he will come back as soon as he can get there. He carries a small amount of equipment in his truck, but sometimes he has to go to the plumbing store to get the right parts. He gives the home owner the choice to put something off if you don't have the finances.
I have been using him for at least 15 years. Of everything he has done in this house, nothing has gone wrong. He has come to my rescue a couple of times, like when I had a flooded basement and a couple of other things. He puts things in right, he puts them in once, and that's the way it's done. His prices are very, very reasonable. If I call him up for a leak, for instance, he will show up within about an hour and a half. If you have an 8:00 appointment, he will be there at 8:00 and if he's not, he will call and let you know or reschedule if necessary. He is very professional. He stays on the job until he finishes the job. He's just a good guy.
Great job! He came out to look at it on Friday (same day we called), and said he could come back Saturday to repair the leak. He showed up when he promised, and finished the job in ~ 20 minutes. It's always hard to get someone out for a small project, and we really appreciate Armor's professionalism and customer service. We will definitely use them again!
He came and got it working. It went out the next day and he came right back. Discovered he needed to replace a switch. My furnace is 35 years old and the company is long out of business. He was able to save me from buying a new furnace by cobbling together a switch from another furnace.
<p>Great he came and shut off the pipes to stop the leaking and then came back within the hour to install a new hot water heater.</p> <p>3rd time I have used his services he is great and dependable,</p>
