Job Locations and Reviews
The GSMS HomeClub heating maintenance was completed on your HydroTherm natural gas boiler. I cleaned the burners and pilot assembly. I checked the operating components of the boiler. I recommend replacing the expansion tank as it is failed. I recommend fixing the piping when replacing the tank since you are not supposed to install an expansion tank in a horizontal position. With the boiler already drained down for that repair I recommend replacing the boiler hyvent and expansion valve. I a.so noticed the age of the water heater being from 2011. I’d recommend replacing the tank to be proactive or installing an emergency shut off valve on the water heater water supply.
Condensate pump failed. It was tripping the GFCI outlet. I replaced it with a new pump and checked operation. I also ran some cleaner through the new one to maintain cleanliness and to clean out the discharge tubing. Thank you!
Prompt. Professional. Caring.
Replacement of your existing power-vented natural gas water heater. No other modifications noted based on the pictures provided.
Today we performed the heating maintenance on the natural gas Nordyne furnace. We also cleaned the humidifier and the drain. We also replaced the humidifier pad. We replace the air filter. Everything looks good and we recommend zero repairs. Thank you.
I repaired a no-heat issue on a Trane gas furnace in Hooksett, NH. The furnace had a faulty igniter, which was preventing the burners from lighting. I replaced the defective igniter with a new OEM part and tested the furnace through a full heating cycle. After verifying that the gas pressure and airflow were within specifications, the system was restored to normal operation. The homeowner now has consistent heat, and I recommended regular maintenance to ensure long-term performance throughout the winter.
Look at replacing shower
Replacement of existing gas boiler with new cast iron boiler. Tuck unit over to the right to allow for more space next to washer & dryer. Also re-do gas piping on exterior due to rust concern and paint. *Pipe to allow for future indirect water heater.
Everything went great.
Performed fall maintenance on a Lennox EL296V furnace. I cleaned the burner assembly, inspected the heat exchanger, and replaced the air filter. Checked the blower motor and lubricated any moving parts. Tested the thermostat to ensure it was functioning correctly, and ran the system through a heating cycle. Everything is working efficiently and ready for winter.
Installed a new Rinnai RL94eP tankless water heater. I disconnected the old unit and installed the new one, connecting the gas and water supply lines. Added a pressure relief valve and flushed the system to remove any debris from the lines. Tested for leaks and ensured the heater was operating correctly, providing the customer with efficient, on-demand hot water.
My mini split needed to be recharged last month during the long heat wave we had. During that service call, they injected something To check for leaks and came back yesterday to see results. They found a small leak and promptly sent my invoice and a quote to repair. No hassles, no waiting.
Thank you for your review, Cheryl! We pride ourselves on training our team to take care of you and your home. Qwentin does a superb job of living up to our GSMS values!
I found that the indoor coil was leaking. I let the client know that the office will get in touch with her with an estimate for replacing the coil.
GSMS had been nothing but exceptional. They installed my mini splits 2 years ago and have continued to provide exceptional service. Qwentin was polite, professional and efficient and did an excellent job. GSMS is my go to!
We’re delighted to hear about your recent experience with us and we’re so pleased that you recommend our services. Thank you for taking the time to share your experience and we look forward to welcoming you back soon!
I started off with washing the outside coil with water. I cleaned the outside of the unit with soap and water. I checked all electrical connections and everything was perfect. I then went inside and I cleaned the indoor coils with water and Dawn soap. I cleaned the outside of the unit with Dawn soap and water as well. I did a pressure check and everything is good.
