Job Locations and Reviews
Completed the electric water tank maintenance. I started off with flushing the tank. I pulled the anode rod and that was in good condition. The expansion tank was in good condition as well. I labeled a few emergency shut off valves. I completed the plumbing inspection. I checked all the fixtures and drains and everything looked great.
When a GSMS contractor comes to your home, it’s not just another contractor doing a job, it’s a personable experience from someone who truly cares about the neatness and quality of their work to the quality of their relationship with you, the customer… they quickly feel like an extension of your family making you look forward to their visits and not feeling concerned in any way how it’s going to go. Always 5 stars from me and two thumbs up, if I can count my big toes, it’s 4 digits up from me!! 👍👍👍👍🙂🙂
Install bypass humidifer. Thank you!
Completed the plumbing inspection. The fixtures and drain lines all looked good. I added a couple emergency shut off tags. I completed the rinnai water heater maintenance. I flushed cleaner through it for 40 minutes. After that I flushed about 10 gallons of water through it. I cleaned the water inlet screen. I vacuumed out the inside of the unit and I vacuumed the air filter. The client was interested in whole house humidification so I will write up an estimate for steam and for a bypass humidifier. The client also noticed that in the summertime the upstairs floor would get very humid.
Completed the plumbing inspection today. All the drains and fixtures looked good. I labeled the main water shut off, the hot water heater shut off and the oil tank shut off. I entered in his equipment to his profile. The water heater is two and a half months old so the maintenance will be done next winter.

I made an adjustment on the Zone First Bypass module. I increased the static pressure at which it will start opening closed dampers. Thank you!
Bad lining switch
Replace burners and inducer coupling. -Coupling is back ordered so we will replace it when we do the AC maintenance or sooner. !
Installed tiger loop
No heat oil furnace. I found that the oil was not being pumped out. I had no oil pressure. I bleed the lines and the pump was still producing no pressure. I purged the oil lines with a vacuum hand oil pump and then replaced the oil pump. I put a new tank filter on as well. I checked combustion and setup oil pressure. Thank you!
The maintenance on your York warm air propane furnace went well. We recommend replacing the coupling in the furnace. It is worn. The heat issue you are experiencing is likely caused by the burners corroding. Sometimes it will burn off in the beginning of the season. We will send a price over to replace the burners. We replaced the air filter today. Thank you!
Installed gas line to future gas fireplace
Repaired water softener
Removal and proper recycling of existing oil tank. New Roth oil tank will be installed to provide oil service to furnace. Oil line will also be replaced with new coated copper line secured with hangers. Price includes materials, labor, and permits and inspections.
Fixed Rinnai wood frame and vibration noise on second floor drastically improved. I mounted it to the foundation instead of the floor joists. I also lowered the pump speed from high to low to improve the whooshing noise the clients were hearing. The record mode is still in comfort mode.
Existing system will be removed with safe disposal set-up through the home's basement access. New system installed with Air Bear Filtration System utilizing 5" thick filter. Supply and return plenums re-worked to fit new system. Outside unit to be in same location. Gas piping installed from proposed gas tank location into home to supply gas furnace and designed with a tee at basement penetration for allowance to expand in the future. Tee also installed at exterior for gas generator installation. BTU's need to be known on generator to properly design and confirm gas pricing. ZoneFirst Zoning system installed to separate first floor from second floor with individual damper control. Existing Ecobee reused for first floor, standard programmable thermostat installed for second floor. Additional supply register installed in great room bump out to provide additional airflow for space.
Polite, punctual, and knowledgeable

Existing Fujitsu system will be properly removed and recycled. Existing penetration will be re-used from exterior. Any interior drywall repair from where the existing Fujitsu unit was is the responsibility of the client. The electrical circuit will be modified to meet the requirements of the new system. Outdoor unit will shift to the left to move away from the dryer vent. A single-zone hyper-heat system will be installed to provide cooling and heating for the front sitting room where the wood stove is located.
