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.

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.

I run Stanwood Anytime Fitness, I found HCA through the help of HCA employee Nathan Collver. The installer Ryan McCluskey was professional and dependable. And Lili Martinez was extremely helpful on the customer service side of things! All in all a great experience.
Home Comfort Alliance (Johnny Weimer) provided superb service by advising me how best to install a security device on my house. His understanding of home construction helped me choose a better location for mounting a Ring sensor / camera / light than I had proposed. My confidence in his advice ensures I will hire Home Comfort Alliance after I complete necessary preparation of the new installation location.
Responsive tech who also performed his estimate after asking good questions in a timely manner. I already have my quote after only two days !
Connor came to our home today to provide our annual service for our furnace and heat pump. He was very professional and thorough. He was a pleasure to have in our home and we would welcome him back for future servicing. Very nice and helpful.
Chris was very through in doing our yearly maintenance on our air conditioning. After Chris completed testing our inline pressure, cooling capabilities, and furnace fan he explained the results of his testing and how they relate to factory recommendations. He was very professional and knowledgeable. I would highly recommend him and Home Comfort Alliance
Thank you, Anton for setting things right with our air conditioner and helping us understand the system. He did a terrific and very fast job.
Ian was professional,polite and very thorough.
Mannie went above and beyond!
Zach just performed the annual checkup on our heat pump and furnaces. He was on-time, efficient, thorough, and informative, all the traits that we have seen for 22 years with MM Comfort/Home Comfort, from installations, maintenance, and repair of the aforementioned systems to their plumbing work. I always recommend them.
Josh, as usual, was prompt, friendly and professional!
Tor from Home Comfort Alliance was excellent in providing routine maintenance to our whole home generator. It was his 2nd visit to our home in each of the past 2 years service visits so remembered where it was. He's a genuinely pleasant guy to chat with as well. He was on-premise for a little over an hour for the work and explained what he found and service preformed in detail.
Allen is professional, knowledgeable and took his time in great detail on what is going on with my AC.
Dylan was excellent and serviced a Reznor, a heatpump and gas furnace combo, and a tankless hot water heater. He was very through, and gave me details along the way and answered all my questions. He didn't try to push extra services or repairs. He found a serious issue with our gas furnace and left me with options for how to move forward on it, and his email to follow up with any more questions I have. Very professional, and a pleasure to talk with.
Fabulous AC maintenance service from Allen Walker, Home Comfort Alliance. Very friendly, informative, and professional.
Great job by the crew.
The fact that it was done in a day is amazing work! Both fellas came up to explain everything and how it works in details. Very professional! Home Comfort did my cousins home in Des Moines and now my parents! Great pricing and service! Definitely worth recommendations!
Anton was very professional and thorough. Great service!
Zach Simmons showed up on time, answered all my questions, and completed the service quickly and efficiently. Great experience!
