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.

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!

Brandon R. came to our home to give us a quote on a heat pump. He was on time and very pleasant. He was thorough in his assessment and answered all our questions with competence. We will definitely be purchasing from Home Comfort Alliance, not just because of the competitive price, but because of Brandon's excellent customer service. 👍

Mr. Victor was friendly first of all, punctual, very courteous, and professional. He also was quite efficient of his time and mine. No unnecessary chit-chat to "show off" an artificial friendliness. He was focused and checked everything needed to be checked and answered all my questions. He gave me some suggestions for effective settings. Overall, I really liked his service. He was the way it should be and I wanted to be as a maintenance service person for my equipment. Excellent work, and I appreciated it.

I had my HVAC installed by G&S Heating (now called HCA) about 12 years ago and have been having it serviced twice a year by them ever since. They send me a remindrr that it's time for a service & always work with my schedule to get an appointment within a few days. Tyler Golden has been performing my Maintenance service for the past several years and I appreciate that he's familiar with my heating system, courteous, friendly & very efficient. I just requested that HCA alway assign him to service my HVAC. HCA has my highest recommendation.

Allen was professional and great technician. He quickly assessed our issue as a leaking fitting and performed a due diligence reviews and was able to tie the leak to a previous repair from 3 years ago. He put together a repair plan to replace the fittings since the most likely cause for a second leak is the known deficiency of those fittings. I'm amazed at how he was able to troubleshoot and make the arrangements to get the repair done. The following week Allen was back for the scheduled repair, and we were back online. Great service!!!
