Washington is our home and we pride ourselves on the service that we give to our friends, family and neighbors. Learn about our long history and reputation for excellence as we've lead the HVAC industry in the greater Puget Sound area for over 40 years.

Our History

G & S, Inc. was founded in 1977 as a residential heating and air conditioning installation company with two employees.  Over the decades, led by Roger Thompson, the company flourished, staying true to its beginnings as a “service first” company.   

Now with more than 50 employees and a fleet of 30 service trucks, the company transitioned from a small installation company to one of NW Washington’s largest HVAC contractors.  In 2018, G&S Heating partnered with another Puget Sound market leader, MM Comfort Systems, to offer enhanced services and products to our clients and leverage the strength of both companies. Since then, three more Northwest Washington home services companies have joined the effort.

Testimonials

Jen in the office and Jacob who came and did the install were awesome. Jen went above and beyond to help us out find information on our old water heater and provide us the best option on a new one. Jacob was professional and did the install super fast. Was very impressed with how fast he was. Also gave us some tips to get some extra life out of our new tank. Glad that we could find a company to service all of our mechanical in a one stop shop. Great to support a local company.

Everyone from Customer Service, appointment scheduling, and service technician, a great team. Allen was knowledgeable, thorough, and he educated us, and prompted us to make wise decisions on getting the most from our heat pump and heating unit. I reccomend G & S Heating, Cooling, and Electric to anyone either looking to buy, or looking to maintain their existing system.

G&S comes out twice a year to keep my heating/cooling system in perfect working order. The technicians are always friendly and efficient. I have used G&S for over 30 years and I have always been pleased. I recommend G&S to anyone that will listen!

G&S Heating was a pleasure to work with.
Everyone connected with the sale & installation of my new furnace couldn’t have been more professional.
Their estimate was much lower for the same furnace than the two other companies I contacted.
I am very pleased.

G&S was able to promptly schedule the installation of a replacement furnace and heat pump. They performed professionally and completely cleaned up the old equipment and any debris.

This business has fantastic communication. They replaced all exterior lighting at my condominium. The work was fantastic and done in the agreed time frame and they even went the extra step to do additional clean up afterwards that was not required. Prior to accepting the job, we asked a lot of them in terms of questions, price options and we emailed them excessively and they were nothing but professional and kind. Highly recommend!

I was given an 8 AM-Noon window for my annual servicing. I was pleasantly surprised when the Service Technician, Dmitriy, called to let me know he was on his way & arrived shortly afterwards. He was thorough & shared with me some regulations that may impact my unit in the future. He recommended I call their office if I would like someone to come out to explain options & costs if I do want to replace my aging system. I appreciated the “heads up.”
Always on time, great customer service from start to finish. I don’t call anyone else, because they are the best.

Quick response and very knowledgeable staff. I’ve had Eric here on numerous occasions to make repairs as well as do a thorough checkup. If you are using another service, like I was, I encourage you to make the change and let G&S be your partner in keeping your heating and cooling system at top notch performance.

An excellent experience from start to finish. William explained everything clearly during the heat pump estimate process and was careful around my dog, who tends to be underfoot. The pre-install visit let us know exactly how to prepare the areas. On the day of the install I had a call 10 minutes before they arrived, and the team did an excellent job. Everything was explained to me and the system is working well.
