Qwentin G.
Upon arrival I found that there was water in the furnace cabinet. I found that the furnace trap was clogged. I rinsed it out with hot water and soap. I primed the trap and reinstalled it. When I went to start up the furnace the same area code came on again. I found that the blower motor has failed. When trying to locate a new motor the rep had told me the best thing to do was to replace it with the OEM motor. We will get back to you Friday and let you know if we can replace it that day.

I found a loose wire in the connector to the inducer motors. I was able to repair it and the furnace is now working. Thank you!

Completed the non condensing rinnai water heater maintenance. I inspected the inside for leaks and there was none. Checked the wiring connections and everything looked good. I checked incoming gas pressure and that was according to manufacturer specifications. I ran the cleaner through it for about 45 minutes. I flushed about 10 gallons of water through it after. Everything looked good on the water heater. The noise with the radiators I believe is that there is air in the system and because the expansion tank is bad. We will come out as soon as possible to replace the leaking trap under the bedroom sink.

Replacement of the existing heating and cooling system with a new high-efficiency and reliable Lennox heating and cooling system. The existing system will be removed. The outdoor unit will be placed in the same location, with a new lineset installed and the electrical circuit modified as needed for the new system. A new bypass humidifier will be installed, along with a new AirBear filtration unit to enhance indoor air quality. System venting will be redone to bring it up to current standards. The existing Nest thermostat will be used for system control.

The water pipes that go to the shower valve pass through a floor ontop of a concrete slab. The joist bays are in-fact insulated. I would reccomend putting heat tape on the pipes. I suggest contacting your property management company first. If they will not do it please give us a call. Thank you!

I found that the louver motor is broken and potentially the plastic housing for the motor. I will send over an estimate to replace the parts.

Qwentin did the annual maintenance on our furnaces. He checked everything thoroughly via checklist and itemized was done.

I found that the boiler was off on a error code because the condensate trap was clogged. It was completely filled with calcium deposits. I pulled the trap apart and I rinsed it out with hot water and soap. I put it all back together and tested operation and everything was working as it should. I found that a connection to the circulator pump inside of the boiler was slightly leaking. I found that the neutralizer beads were caked up with calcium deposits as well and found that the high vent was leaking. The heat exchanger was also pretty dirty inside so I will send over an estimate for those repairs and cleaning of the heat exchanger.

I found that the gas valve was faulty. I replaced it with a new OEM gas valve and a propane conversion kit. After I reconnected everything I tested for gas leaks and there was none. I checked incoming gas pressure and I set outgoing gas pressure to manufacture specifications. I cycled the unit 10 times. I performed a combustion analyzer test that checks the units CO, CO2 and oxygen levels and everything was running good.

Review
The experience started with Gina in the office who was very responsive and accommodating and made the scheduling process super efficient and friendly. Then Mark came and brought his expertise to my home and systems to point areas of installation failures by the company that installed my system. Just using the basic manual to point out how they cut corners. Mark spent the time to correct the exhaust piping to fix leaks and improve air flow. He was friendly and accommodating.

Whenever Mark is on the way, you know it’s gonna be fixed correctly. He is awesome!

GSMS is a great Family owned Company to work with. I am very happy with my new Boiler heating system. Zak explained all my options and was prompt to call back with any questions I had. Adam, the lead Technician was outstanding with the installation. Gina was great coordinating the scheduling. Mark also came out for a final inspection. You can tell they take pride in their work! I would definitely recommend them.

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.
