Today we performed a maintenance on your furnace. The only problem we found was a cracked fitting off of the inducer. We were able to reseal it with hugh temperature silicone. I highly recommend planning on replacing the furnace due to its age. I spoke with Ian and he would like an estimste set uo with Zak. Gina will reach out to book that. We added hangers to the unsupported gas line.

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.

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.

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.

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.
