Quick service




This is my first time using G&S and have to say that they have been easy to work with. Very good communication and Ryan was cool. I had a condensation leak, he patched it up and did some minor cleaning while out. I look forward to working with G&S in the future. Actually I have just booked a full AC Central system install.

Allen was especially helpful today as my furnace is very old.




Allen showed me what it would require should my 30 yr old furnace quit working. He suggested I be proactive before that happens. He also went over my Honeywell thermostat explaining the advantages of a newer model. He has serviced my furnace before and is always professional and friendly.

Ryan Kelleher not only gave us great service (keeping us from experiencing a freezing night by quickly fixing our heater) but also made his visit a pleasure by his ready smile, friendly service and great advise. We would like to have him should we have any future problems. Randy Ticer

Great Technician! Great Company!




Allen did a great job at our residence! He explained everything he was doing and why, how my system worked, what I could do to maintain the system and what to look out for. He was fast and efficient. The scheduling with GS was easy. It was like calling a long lost friend since the previous owners of our residence had contracted with GS. I was so impressed, I signed up for a regular inspection/maintenance plan! Thanks GS!!!!!!
