Well tank replacement model Amtrol WX20.

Review
My call for service was answered promptly and the service technician showed up promptly at the time stated. As always, Mark was courteous and professional. From wearing shoe covers for walking through the house, to listening to my concerns and questions, and thoroughly diagnosing any problems, he provides top-notch customer service. Additionally, I am absolutely impressed at how GSMS backs up their work and the products that they sell. I feel I have always been treated fairly and reasonably charged for any work that has been done. GSMS by far is the best heating company that I have worked with. I wholeheartedly recommend them to anyone looking for a heating contractor.

Installation of a single-zone mini-split system to provide the sunroom with cooling and supplemental heating. Client will build a "wall" for us to mount a unit stand for the outdoor unit on the side of the deck. This will be to help prevent any water run-off damage. Client will also DIY electrical circuit for us, following code and pulling respectable permits needed.

I performed a plumbing repair in Barrington, NH by replacing the worn-out springs in a faucet. The old springs were causing reduced water flow and inconsistent pressure. After removing the faucet assembly, I installed new springs from the original repair kit, ensuring proper fit and function. Once reassembled, I tested the faucet for leaks and flow, confirming that the water pressure was restored to normal. The system is now functioning correctly, and the homeowner was advised on maintenance to avoid future issues.

Replacement of existing oil-fired furnace with new heat pump full electric system. No backup electric heat. System not designed for AC load based on knowledge of ductwork being uninsulated in wall cavities. Oil tank removed. System is undersized for home heating load due to limitation in equipment offering. We will construct a poured concrete pad for the unit stand to be placed on instead of our standard procedure.

Performed fall furnace maintenance on a Lennox SLP98V system. Inspected the heat exchanger, cleaned the burners, and checked the blower motor for wear. Replaced the air filter and tested the flame sensor for proper operation. After completing the tune-up, I ran the system to ensure it is operating safely and efficiently, preparing it for the cold weather ahead.
