heater installation




Mike and crew showed up right on time. They went over everything they would be doing. I checked on them periodically and they spent time with me explaining all the steps and installation details. They cleaned up when they left and the heater is working perfectly.

Fantastic Install Experience!




Replacing the furnace and water heater (from electric to gas) in my rental was a long time coming. William at G&S was infinitely patient as I dove into detailed minutia asking multiple, specific questions In order to compare apples to apples as I dissected the bids obtained for the project. The installers were AMAZING. They were respectful, good natured, kept the site clean and clear for my tenants, and were able to keep the house heated save for the morning it took to swap out the furnaces. We were told to expect one night without heat. Not unreasonable given all the moving parts. Izaak was able to manage the install, and then schedule both the city and utility inspector on the same day, so my tenants essentially never lost heat, in October. We’re all delighted!

Good Service - Appointment slipped




Eric, the tech, did a great job in inspecting, explaining and answering questions - most highly recommended. The office had an issue with scheduling but didn't contact me until well after my morning window had passed. Sincere apology was appreciated.
