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.

What our Customers are Saying!

Second time using this company and they always do a great job! Quick to respond and friendly/knowledgeable techs.
Allen from Home Care Alliance did a great job on my old furnace. I asked lots of questions and he answered them all so I can understand what is going on. Thank you Allen.
Allen is a great guy gives great tips to keep our new gas furnace working at top efficiency
Reylli was amazing, going above and beyond for our AC cleaning and even showing my little one what he was doing as he went-clients for life!
DaMarco did an excellent job! And I admire his patience with a needy homeowner (me).
Home Comfort Alliance installed a heat pump for us a couple of years ago and were very professional, efficient, clear, and reasonably priced. We've since had two annual service visits for the furnace and heat pump. Keith did a fantastic job on our latest one - he was super transparent, quick, and helpful. I'll gladly get more annual service visits to keep our extended warranty and hope I have Keith for all of them in the future!
Quality service
It depends on the tech how your experience goes . Today I had an excellent tech who knew immediately that another tech had not replaced a screw inside the furnace last Sept. this tech also gave me good advice on ordering a particular filter that would last for the year before the yearly maintenance.
I've been struggling for years since I installed the AC, but today it seems that my heart has healed. Drew was so kind and explained so well step by step. It was a very difficult task to remove all the ACs that had been installed and do it all over again, but they did a very sincere and meticulous job. Even the pipes that looked dirty were organized so well that they didn't look bad on the outside. I feel sorry to give you 5 stars, but I think he deserves 100 stars. You'll probably be lucky to meet him.
It has been a pleasure to work with Home Comfort Alliance, from the excellent consulting Bobby Baker provided, to the meticulous installation of the Mitsubishi heat pump by the electricians, and Drew and Jeremy. Congratulations to them for a job well done!
My furnace was giving error codes which warranted a technician visit. Home Comfort Alliance sent out Allan Walker the next day (we still had heat). Allan was professional and thorough. He took the time to explain exactly was was happening with my furnace. He also answered my questions about my water heater and preventative maintenance. We even discussed energy/cost saving measures I could do to improve the efficiency of heating my home and providing the best air circulation. It is so nice to have someone do a service call who is knowledgeable and genuinely cares about helping the customer. Home Comfort Alliance is fortunate to have him on their crew. When I called to discuss my furnace concerns Chandler was efficient and helpful.
All aspects of the service were great! I really appreciated the friendly answer of my phone call and the quick scheduling of my service appointment. Technician Marcus was great! Professional, on-time, friendly, and great with my two dogs. Happy to have a reliable HVAC service provider in our area!
Very good service tech. Explained every thing to me.
Response from the owner:Thank you for the five star rating, Tom!
Awesome service, punctual and professional. Dan was great. Super knowledgeable and patient with all my questions. Can recommend👍🏼
This is the 3rd year that Home Comfort has serviced my system and again…incredible service. Dylan Brown has been the service persons for two years and he is just amazing. VERY thorough!!! And even spent some time further explaining how to get the most out of my system. Thank you Dylan and Home Comfort!!! See you next year.
The team at Home Comfort Alliance were superb! Cheryl, Nate and Anton. They answered all my questions, gave me a great comparable estimate after a site visit. I would 100% work with them in the future for any heating/HVAC repairs.
Allen did a great job. Very courteous, professional, and personable.
We had Anton from HCA come out and do maintainence on our Mitsubishi Split. He was on time, professional and was willing to let me observe and ask questions. Would recommend highly!
