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.

Great communication with the company/office. Scheduling was easy and flexible. Isaac was on-time, explained that he was here to clean and inspect the furnace, and got right to work. When he was finished he told me what he'd cleaned and tested, and that he'd changed the filter. He'd even fixed the filter cover (it was bent when we purchased the house) so the cover now fits properly. Isaac was very professional, polite, and efficient. And just as importantly, he had a great sense of humor.

Isaac Schmitt with Sullivan's AC/Homecare Alliance was wonderful! On time, great attitude and provided answers for all of our questions. He was even friendly to our "energetic" dogs and gave us some potential tips for reducing dust in our home. People like Isaac will keep us coming back to you all for future service needs!
