Completed the plumbing maintenance today. I started off with flushing the water tank. I labeled a few emergency shut offs. I inspected the drain pipes downstairs and the client was saying that there was a leak at some point. The area was still a little wet and I believe it is sewage. I told her that we can come out and take a look and she said that she would let us know.
Found that the thermostat wire was grounding out somewhere. I used one of the extra thermostat wires.
Replace old moen single handle shower cartridge.
Replace moen kitchen faucet cartridge.
Replaced the failed expansion tank for the domestic water. Checked and there was no leaks. The homes pressure is 100 psi. The state code is that if it exceeds 80 psi than a pressure reducing valve needs to be installed. I will send over the estimate for the PRV.
Tankless Water heater planned service. Everything went great on todays visit.
Removed old boiler. Tightened tankless coil
It’s always a pleasure when Qwentin stops by; a polite and personable young man who is an asset to the formidable GSMS team who did another super, duper jobby! 😉 Hope he had a great time at the party celebrating multiple birthdays this weekend?! Cheers 👍🙂🥃🥃
Replaced gas valve under warranty
I was able to remove the old cracked leg and add a new one in. The unit was still pretty wobbly due to the concrete pad not being level. I used a rubber furnace block to shim the new foot. The unit is nice and sturdy now.
Performed a deep cleaning on the mini split head in the IT room. I took a before and after video. Turned it back on to 64 degrees in cooling mode.
Adam & Quinn just left after finishing the installation of my new Lennox Air Conditioning unit. As always, they are very personable and professional. Adam explains everything to me before he leaves and I am very comfortable with my new system. I would not hesitate to recommend GSMS and have done so in the past.
Qwentin was thorough and diagnosed the issue

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.
We thank you for sharing your positive experience. It made our day.
