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.

Brandon came by to give us an estimate for a heat pump and furnace replacement. He arrived on time, was professional, curtious, and knowledgeable. He took measurements, counts and reviewed old equipment. The estimates were competitive, plus he explained about the rebates and tax credits available. We accepted his offer and he will fill out all the paperwork for getting rebates. The communication has been good so far. System will be installed next week.
Home Comfort Alliance have been doing the maintenance on my heating and cooling systems for the last four to five years even when they were Sullivans heating and cooling and they have a great team of professionals. Issac has been our service technician for the last three services or more. During this service I noticed how detailed and dedicated Issac is, he takes detailed notes on my heating and cooling systems so he can track the wear on important parts in the system and he lets me know what he did and what will need to be done next time. He always sends me a copy of all the readings and what maintenance that was performed. I am quite pleased with Issac’s professionalism!
Steven the technician was very professional and helpful
Carter was professional and courteous during the maintenance of my heat pump and HVAC system. He was very informative. Thanks!
