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 overrun, schedules 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 advisor Project Management designed to define and meet your expectations every time. We’ve been specializing in HVAC related projects since 1965, so we know buildings and we know how to get projects done on time and within your budget.

Comfortable Environments. Smooth Projects. Energy Efficiency. Tenant Retention. If these are the concerns you have, call on the company you can trust: Home Comfort Alliance.

Tenant Improvements

When you want it done yesterday, call us today.

Every time a tenant leaves, there’s potential for expensive downtime until a new tenant moves in. But you can drastically reduce downtime and ensure a smooth, quick transition by calling in the Home Comfort Alliance Special Projects & Tenant Improvements team.

We're extremely aware of the importance of responding quickly to your tenants’ needs. Because of this, we have assembled a quick-response team that excels at performing work on very fast track projects.

And we don't just do our work fast, we do it right. Whether you're changing office space, revising computer room systems, correcting poor zoning, or undertaking any other kind of tenant work or retrofit project, you're assured of Home Comfort Alliance quality and attention to detail throughout.

This all adds up to the fastest, most comprehensive, experienced, and expert remodeling and retrofit team available. But of course, you wouldn't expect less than that from Home Comfort Alliance.

What our Customers are Saying!

Great plumber, knowledgeable, courteous and got the job done in a reasonable time.
Bob Baker went above and beyond with our older home. He took the time that other didn't to explain what would work best in our situation. Thanks Bob
Dan Kinzler of Home Comfort Alliance technician was on time, very professional and friendly. Our experience with Home Comfort Alliance was quick , worth the time and money!
Our tech, Carter arrived on time, and explained the service he was going to complete on our furnace, water heater, and air conditioner. He is very professional and thorough in his work, leaving a clean site when completed. Carter made sure I understood everything before he left and thanked me for using Home Comfort Alliance. I recommend HCA for your needs
Cody was knowledgeable and explained everything clearly while in the process of our annual system maintenance. Very pleased!
Always reliable and knowledgeable
Steve was awesome! He was able to get our air conditioner working and completed the maintenance of our ductless system! I highly recommend!!
I have depended on Sullivan (now HCA West) since we bought our home on Bainbridge Island 15 years ago. They have always provided excellent service and maintenance. Four years we decided to upgrade our heat pump system, and their help, options, and work has made our home a perfect climate year round. Recently Dan came out for our yearly maintenance, and he was thorough, friendly, ready to answer my questions, and did his job perfectly. Thank you so much HCA, Dan, and all your workers — in office and in the field.

Victoria
Great job. On time and will replace fan motor soon. Our unit is working but fan motor is not functioning as it should.
Appreciate the technician (Reylli) coming out and serving out AC/heat pump. He was thorough, let us know of any issues and gave us a couple of suggestions for further maintenance that we might want to follow up on. He came within the appointed time and was courteous. Great job - thank you!
Carter did a wonderful job for us! He explained, what was being done, answered questions, and was very easy to talk with! We even shared about our cats!!
Home Comfort Alliance has just done service and maintenance for my Mitsubishi split Htg & AC system. I have to recommend service technician ISAAC who was efficient, courteous, professional and very knowledgeable. Thank you, Isaac! I am now signing up for annual service with Home Comfort Alliance!
