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 overruns, schedule 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 advisors. Our mission is to ensure that your projects run smoothly. When a project isn’t effectively managed, various issues can arise: costs can exceed budgets, timelines can be delayed, building occupants may voice complaints, and overall efficiency can be compromised.

At Home Comfort Alliance, we recognize these challenges. That’s why we take a proactive and comprehensive approach to defining, designing, and delivering every project. Our professional and trusted project management services are tailored to meet and exceed your expectations every time. With over 50 years of experience specializing in HVAC-related projects, we understand buildings and know how to complete projects on time and within budget.

Comfortable Environments. Efficient Projects. Energy Savings. Tenant Satisfaction. If these are your priorities, reach out to the company you can trust: Home Comfort Alliance.

Tenant Improvements

When you need it done quickly, call us today.

Every time a tenant leaves, there is potential for costly downtime until a new tenant moves in. However, you can significantly reduce this downtime and ensure a smooth, swift transition by reaching out to the Home Comfort Alliance Special Projects & Tenant Improvements team.

We understand the importance of responding quickly to your tenants’ needs. To address this, we have assembled a quick-response team that excels in fast-tracking projects.

Not only do we work efficiently, but we also ensure high-quality results. Whether you are changing office spaces, updating computer room systems, correcting poor zoning, or undertaking any other tenant-related work or retrofit project, you can count on Home Comfort Alliance for quality and attention to detail throughout the process.

All of this makes us the fastest, most comprehensive, and experienced remodeling and retrofit team available. But of course, you wouldn’t expect anything less from Home Comfort Alliance.

What our Customers are Saying!

Home Comfort Alliance (formerly G & S) has consistently provided fast, friendly and knowledgeable service. Our tech Tyler did a fantastic job and provided excellent recommendations.
Response from the owner:Thank you for your kind words, and we appreciate your continued business, Dennis!

He was very thorough. He gave the AC and furnace attention and made sure his gauge readings were spot on.

These technicians were on time and let me know step by step, what was going to happen. Very professional.

Andrew serviced our heat pump and gas furnace. He was on time, courteous, thorough, and answered our questions. We recommend him and Home Comfort Alliance.

Kevin is a professional technician — efficient, polite & friendly.

Great service

Lucas was quick and professional. Assured me that with just one person in the house I didn’t need to change my air filters as often. Recommended the service plan for the next year so I could pay significantly less to have my furnace serviced next time and if I need anything in the meantime it’ll be less. Made sense.

The technician (Allen) was right on time, performed his tasks quickly and efficiently and even took the time to answer my questions about other equipment at a different property

Great service. On time and very friendly Technician.

Kyle provided exceptional service. Showed up on time. Provided annual service maintenance to the boiler. Thoroughly explained the critical components of the system and discussed their critical life span. An exceptional technician and all around nice guy.

Joshua worked on our Furnance this morning. He took his time to ensure everything was working per specifications and didn’t leave until all the testing was done. He was very efficient with his time management.
Hope he can come back next year!
He was very thorough and professional.
Thanks Joshua!

Tor is extremely knowledgeable, thorough, and honest. He goes above and beyond to satisfy his customers. It is always a pleasure to have him come to my house. I have the utmost confidence in him.

My technician was knowledgeable, courteous, and efficient. I highly recommend you get your service done with this company.

Brad Johnson is an incredible technician. Very professional, punctual, good humored, efficient, finds the issues quickly and explains options in terms a non-expert can grasp and support. Brad is the reason along with his service team at the office, that we keep asking for him and his company to handle our account.
