Commercial HVAC
Design and Build Services

Our commitment to your commercial HVAC design & build goes far beyond merely meeting a schedule and staying within a budget. Before we cut a single piece of sheet metal, we carefully plan every aspect of the job, coordinating with other trades and figuring out the smallest details in advance.

Project Management

Our job is to make your projects go smoothly. If your project is not properly managed, a lot of things can go wrong: costs overruns, schedule slip, building occupants complain, and efficiencies are lost.

At Home Comfort Alliance, we understand, which is why we take a proactive and comprehensive approach to defining, designing, and delivering every project. We provide professional, trusted advisors. Our mission is to ensure that your projects run smoothly. When a project isn’t effectively managed, various issues can arise: costs can exceed budgets, timelines can be delayed, building occupants may voice complaints, and overall efficiency can be compromised.

At Home Comfort Alliance, we recognize these challenges. That’s why we take a proactive and comprehensive approach to defining, designing, and delivering every project. Our professional and trusted project management services are tailored to meet and exceed your expectations every time. With over 50 years of experience specializing in HVAC-related projects, we understand buildings and know how to complete projects on time and within budget.

Comfortable Environments. Efficient Projects. Energy Savings. Tenant Satisfaction. If these are your priorities, reach out to the company you can trust: Home Comfort Alliance.

My furnace went out on a weekend. Technician walked my through how to diagnose the problem over the phone, saving me a expensive weekend house call. They fixed the furnace the next week after ordering a part. Great service!

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.
