Completed the plumbing maintenance and inspection. I started off with draining both electric water heaters. I checked the anode rods and those were in good condition. I checked the expansion tank and that was good as well. I labeled a few emergency shut off's and I showed the client where they were. I went around the house and checked out all the drains, water lines and fixtures, everything looked good.

The existing ductwork connections will be remade to the new system, and both returns will be reconnected. A new lineset will be run from the outdoor unit to the interior. If a new line cannot be run, we will purge and clean the existing lineset using our cleaning agent. Outside, a new heat pump unit will be installed on the existing concrete pad.

Adam & Quinn just left after finishing the installation of my new Lennox Air Conditioning unit. As always, they are very personable and professional. Adam explains everything to me before he leaves and I am very comfortable with my new system. I would not hesitate to recommend GSMS and have done so in the past.

I needed to have shut off valves under my kitchen sink and a new hose attachment on my sprayer since the cheap plastic tubing was cracked. Mark was punctual, professional and extremely knowledgeable regarding the job. I am always impressed with GSM and how they run their family business. Mark completed the job quickly and efficiently. I can trust GSM and will continue to seek their help in the help in the future. GSM has installed a mini split, oil boiler, hot water heater in my home and I would highly recommend them to family and friends.
We thank you for sharing your positive experience. It made our day.
