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!

They arrived when they said they would. They were friendly knowledgeable and did the small job cheaper than I expected!
I have been a customer for several years. Their tecs are always polite and expert. I will continue to use them as I value their performance. My tec is Allen Walker. He has been my tec for a long time. He always does his work superbly. He knows the answer to any question I have ever asked. He explains the reason why the answer is what it is. I would follow him if he ever went to another company. Allen Walker serviced my furnace again yesterday, 9/24/24, and as always did a great job. Very pleasant to work with.
Allen Walker came by for routine inspections. I watched him “tune” my air conditioner’s top grill. I could barely hear the noise but he tuned it out of existence. He always goes beyond expectations.
Response from the owner:Yes, we replaced your gas furnace and air conditioner years back. Thank you for the wonderful opportunity and continued business in Arlington, Carey.
The technician, Torf, was polite and professional. He has been at our home before and always explains what he’s doing and gives us tips on the use of our HVAC system. He’s the best.
We had new furnace and AC unit installed a year ago by Home Comfort Alliance. Jorge recently completed our first-year maintenance, and he did an excellent job. He thoroughly checked everything and took the time to explain everything in detail. We truly appreciated the quality of his work.
Allen Walker did a great service call. He thoroughly inspected and tested our current system and gave us helpful maintenance tips.
Quickly determined the problem, got the parts and had them quickly and efficiently installed. Good fast quality service as usual over the year's.
Allen was very thorough and did an excellent job of explaining the necessary maintenance.
Steve figured out our furnace/heat pump trouble, explained it thoroughly and it wasn't even the furnace/heat pump. Our trouble is the circuit breaker. Very helpful.
Allen Walker has been our regular service technician for years. He is always pleasant, professional, and efficient. I appreciate the care and respect he shows for his customers and the great work he does.
Excellent service visit. A pleasure to deal with him
Very pleased with service. Issac Schmitt, arrived promptly at 8:00. I explained the problem, he was very attentive and courteous. He found the issue, explained it to me and took care of it. Issac’s service was professional and friendly, very pleasant experience.
Very nice guy and efficient!!!?
Steven is such a positive technician. He went through everything he was doing and made sure I understood.
