I found the old valve that serves the out door faucet to ve the cause of the leak. I quoted a replacement. Thank you!
I believe the burning smell was caused by loose insulation threads making contact with the hest exchanger. I removed the threads and the smell went away.
Completed the furnace maintenance today. I started off with checking all the wiring connections and everything looked good. Next I pulled and cleaned the flame sensor. I replaced the air filter with a 20x25x5 air bear filter. I checked incoming and outgoing gas pressures and those were according to manufacture specifications. Lastly I ran the unit in low and high fire and performed a combustion analyzer test. This checks the units CO, CO2 and oxygen levels. The furnace was running great. It is too cold outside to complete the AC maintenance so we can reschedule for April to May.

I found the leak at the water heater to be caused by a leaking expansion tank. I replace it and tested for leaks. All set thank you!
Completed the gas furnace maintenance today. I started off with checking all the wiring connections and everything looked good. I pulled and cleaned the flame sensor. I flushed the trap and condensate pump with cleaner. I vacuumed out the inside of the furnace and the filter box. The air filter looked very clean so I left it in. I checked incoming and outgoing gas pressures and those were according to manufacture specifications. Lastly I ran the unit in low and high fire and performed a combustion analyzer test. This checks the units CO, CO2 and oxygen levels. The furnace was running great!
Excellent service and communication. A great family business.
This is the ultimate purity option, using advanced "smart" technology and a space-saving design. Scope of Work: Install a DROP Smart RO unit horizontally in the cabinet beneath the kitchen sink. Space-Saving Design: Because this unit is an all-in-one system, it does not require a separate large holding tank. We will install it horizontally in front of the garbage disposal to maximize your remaining cabinet space. Primary Benefit: Removes up to 99% of contaminants (lead, fluoride, arsenic, and PFAS) while delivering the highest quality drinking water available. Smart Features: * Built-in Leak Protection: Automatically shuts off the water if it detects a leak under the sink. Real-Time Monitoring: Sends alerts to your phone via the DROP App when it's time to change filters. UV Disinfection: Includes a built-in UV stage to ensure the water is bacteriologically safe. Utility Requirements: This unit requires a 110V electrical outlet to power the internal pumps and smart features. Gra
Professional service
Full explanation of the work to be completed and suggestions for future services . Answered all my questions. Very professional and knowledgeable.
Both guys very helpful & solved the problem
Very knowledgeable & very helpful
Friendly and transparent. Explained all aspects of the service.
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.
A+
