Heat Pump Installation, Maintenance & Repairs

Heat pumps are wonderful and energy-efficient systems. If you’re a homeowner interested in saving both money and going green, consider the option. They work by exchanging hot and cold air from within and outside of a home. This is a more energy-efficient alternative to standard units that warm or chill air themselves. For Sammamish homes interested in considering this technology or if you have any other inquiries, contact our team today. For residents who already have a heat pump system and are interested in repairs or maintenance, contact us today and get in touch with one of our knowledgeable team members to handle any of your needs.

Electric and Gas Furnaces

A popular heating choice for Sammamish residents is the electric furnace. Electric furnaces operate a lot like hairdryers. They pull air in and heat it by using electricity to get their internal electrical components hot. As air passes over these heated materials, it too warms. Then the heated air is redistributed back into a home to provide heating. They’re common, simple, and safe. Home Comfort Alliance has decades of experience working with them.





In the other corner are gas furnaces that are also great for your home. Gas furnaces are a great choice for many Sammamish residents. Gas units can warm a house very quickly and provide enormous heat output that often cannot be matched by alternatives.

We just purchased our home and needed both furnace and AC servicing. We called Home Comfort Alliance (previously GS Heating) since they installed the AC unit for the previous owner a couple of years ago. We were able to get an appointment that worked for our schedule in just a few days. The technician, Anton was great. He was on time, courteous and very knowledgeable. He mentioned that our systems were still running great and he didn’t try to push us for a new system. Anton even took the time to explain our (new to us) Honeywell thermostat and how best to set it for our home. We also appreciated HCA’s prompt communication for the appointment confirmation, technician arrival and invoicing. We had a very positive experience and will continue to use Home Comfort for our maintenance needs.
Response from the owner:Thank you for the glowing review! We appreciate your trust in Home Comfort Alliance for your HVAC and home comfort needs. Our locally owned team is proud to serve communities in the greater Puget Sound region with dependable, energy-efficient solutions.

Wonderful customer service! I had both Isaac and Brad as technicians to help fix my Central Heating/Cooling system that was damaged in a power surge.
They were both very helpful and completed the job successfully and efficiently.
And the company is very accessible and quick to answer their phone and set up appointments. 🙂
Response from the owner:Thank you, Kristine! We’re glad Isaac and Brad were able to get your heating and cooling system back up and running after the power surge, and that everything was handled efficiently. We also appreciate you mentioning how easy it was to reach us and schedule—thanks for choosing Home Comfort Alliance – Bremerton.

Four months ago Brad was here to fix our heat pump. Yesterday he fixed the cooling unit for the wine cellar. He is a great trouble shooter, undaunted by challenging problems. The item he replaced was covered by warranty, but the labor wasn’t. To my surprise and great satisfaction, HCA covered labor anyway. The wine cellar is, now, working perfectly, at no cost to me.

Brad was thorough, knowledgeable and friendly. We are very happy with the service from Home Comfort Alliance. We recommend them highly.
