About Us

United was established by Billy Henderson in 1985 and was known as Henderson Heating & Air. We started as a small company handling residential new construction and service work. In 1992 Henderson Heating and Air bought another small air conditioning company and merged the assets and manpower to become “United”. We started doing light commercial HVAC in the mid ’90s and we continued to grow into a larger air conditioning and heating company so that by 2000 we were one of the top 3 residential air conditioning companies in Montgomery, Alabama. In 2000 we began to pursue replacement in existing homes and build up our service department. Beginning in 2007 we added a plumbing department that includes service, repair and new construction. In 2014 we started our electrical department doing new construction and now can handle small commercial and residential service. With over 200 years combined experience we can handle all your heating, cooling, plumbing and electrical needs.


If Air Conditioning Installation was easy we would all do our own.

I am writing to you in regards to your installation of August 25th 2015. Words that come to my mind are “PROFESSIONAL, KNOWLEDGEABLE, SKILLFUL. CLEAN, RESPECTFUL, HARD WORKING. It started with Mr. Bryan Anderson. (Thought he was just a salesman), but quickly found out he actually knew something, after his consultation, which included checking duct work, and “correct sizing and matching the correct air handling system with the outside unit “he explained the advantages of the system we were interested in..

Now we come to Drew and his team:

It was quickly apparent that these men already had a plan of action. There was no hmm, hmm, hmm, they had everything laid out and went right to work in all that heat, one of the hottest days of the year. (I know they do this for a living, but they did not miss dotting an “I” or crossing a “t”. A great big (KUDO) from my wife(who suffers from allergies) and me.

Everything , so far, has working as advertised and better !!!

Thank You from both of us

I had 4 estimates from well known companies, and the one I liked was United. Your specialist was the only one that tied things together for me in a way I understood and felt comfortable with. The installation crew was equally impressive. After the installation, I know I made the right choice, and have found my go-to company for as long as I remain in this area. I could not be happier. I've already referred United to two of my close friends!

After adding Freon for several years, I decided that this year I was going to get a new and more efficient heat pump. After much research, talking to several companies and getting quotes from three, I decided to go with United’s Goodman heat pump. There were several things that lead me to the decision but one stood out from the rest.

United’s Supervisor/Salesman (Danny Carter) not only went up and beyond in providing me with the information I needed, I felt that he had a real desire to help me make the best decision. He, along with his installation crew (Shane and Terry), displayed a courteous professionalism that you rarely see with companies these days. Not only were they respectful to my needs, they obviously had respect and pride for their company and the Goodman product as well.

A big thanks to these guys for making what would normally be a not so pleasant experience much better. With that along with the team’s obvious technical expertise and my feelings that the ultimate quality of the heat pump system comes mostly from the install, I’m sure I made the best decision. No complaints here. Way to go United!


I wanted to write to you and tell you how pleased I am with your company and your services. I thank you so very much for helping me in my time of need  I also wanted to tell you how much I appreciate your guys, Sean & Drew. They both went above and beyond the call of duty and did and excellent job.

It has been a pleasure doing business with your company


We have used United Heating and Air since we started building homes in 1989. They have always stood behind their work and are concerned about the quality of the job they perform. Having a 24 hour on call technician to respond to problems when they occur has been a comforting factor for our customers. They are always professional and courteous when dealing with the the homeowners. We would recommend United to other contractors, but we feel like they are one of our secret weapons on being so competitive.

It ‘s been almost a year since your company installed my new Goodman heat pump and Marathon hot water heater. Both have been operating flawlessly and I am showing substantial savings on my electric bill compared to my old heat pump. The installation went well and your installers were very professional. I initially had a thermostat problem, but your service department responded almost immediately and resolved the problem with a replacement thermostat.

For many years I was a sales engineer for York Heating and Air Conditioning products. Consequently, I know a good product and installation when I see it. And your company provided both to my satisfaction. I will recommend United to any of my friends who may be in need of your service or products. Thanks for everything.
