I replaced the three-way valve today. After installing it I turned on both heating zones and made sure the returns came back hot. I had the client turn on the hot water and there is no loud clunking anymore when the three-way valve engages.

Qwentin G.
Completed the Rinnai tankless water heater maintenance. I started off with running a cleaner through it for 40 minutes. After that I flushed 10 gallons of water through it. I cleaned the water inlet screen. I cleaned the air filter. I cleaned the flame sensors and electrode. I checked incoming gas pressure and that was according to manufacturer specifications. I checked the water heater accessories and everything looked good. I labeled a few emergency shut off's. I completed the house plumbing inspection. I checked all the fixtures and drains, everything looked good. When we come out for the AC maintenance the client would like us to bring 2 water filters for her home. The client also wanted us to replace her garbage disposal whenever we have availability.

Qwentin G.
Completed the Rinnai tankless water heater maintenance. I ran cleaner through it for 40 minutes. After I flushed it with 10 gallons of water. I cleaned the water inlet screen. I vacuumed the air filter and the inside of the water heater. I checked incoming gas pressure and that was according to manufacturer specifications. I completed the plumbing inspection. I checked all the fixtures and drains and everything looked good. I labeled some emergency shut off's and showed the client where they were. I took a look at the furnace and saw that it was leaking water from the collector box. I will send over an estimate to make that repair. Regarding the tub leaking through the ceiling, either the gasket is bad or the drain pipe isn't connected behind it.
Manchester, NH 03104
Qwentin G.
Completed the plumbing inspection today. I checked the fixtures and drains and everything looked good except for the first four bathrooms drain. The Trap was loose and was leaking a good amount of water out. The client is going to repair it on his own. I labeled a couple emergency shut offs. I noticed that the boiler had some soot near it so I pulled a combustion test. It was a little rich so I leaned it out and pulled a smoke test and got zero smoke.

When a GSMS contractor comes to your home, it’s not just another contractor doing a job, it’s a personable experience from someone who truly cares about the neatness and quality of their work to the quality of their relationship with you, the customer… they quickly feel like an extension of your family making you look forward to their visits and not feeling concerned in any way how it’s going to go. Always 5 stars from me and two thumbs up, if I can count my big toes, it’s 4 digits up from me!! 👍👍👍👍🙂🙂

We had an issue with our furnace and called GSMS on recommendation from a friend. I called and spoke with Gina to schedule an appointment. (She is very pleasant with a great attitude!) A service specialist, named Qwentin, came out to assess the issue. Qwen is great! He spoke well and is quite knowledgeable. He explained the issue, proposed a solution and a provided quote to fix. Although he didn’t have the part, he indicated he would quickly leave, go get the part and come right back to install—- all in that same visit! Qwentin‘s customer service skills, along with everyone else I’ve spoken with at GSMS, are top-notch. Going forward, we will use GSMS for our Plumbing, Air, Heating needs.

Adam, Quin and Mark did a wonderful job installing my replacement oil boiler and oil tank. I have trusted GSM for 3 installs at my house because of their professionalism, workmanship, honesty, transparency and integrity for how they conduct their family business. Everyone who has worked at my house has always been informative, on time and respectful. I would recommend GSM to anyone who needs to have major plumbing or heating/cooling done in their home. Gina in customer service is the best at relaying information and gets back to you in a timely fashion. Zak is wonderful to work with and the entire team at GSM treats you with kindness. Thank you again for another wonderful experience because when it comes to your home it is one of the largest investments you will make in your life, and I trust GSM to be there for me in the future.
