The technician was very professional and informative concerning our particular situation. Answering all our questions and at no time did he seem rushed or put out at all. Very courteous and knowledgeable young man.

Great experience with Gilbert at Allegiance. He came out to perform our annual furnace inspection. Process was timely and professional. Thank you Gilbert!

Gilbert provided outstanding service. He explained what was needing to be repaired, and provided several estimates for me to choose from. I highly recommend Allegiance to family and friends!

"They are our go to for all of our HVAC needs. Prompt professional and accurate…not to mention local and affordable. If you don’t have a mainmaintenance agreement or service plan, Allegiance‘s plan is the best in industry, give them a call to discuss."

"My heat pump went out and I had to call after hours. The technician (Garrett) was outstanding and thorough. He got my system up and working until Monday and gave me several options of units. Also took the time to explain the issue to my Home warranty company. I highly recommend this company."

"Main floor HVAC system went out and they had the tech out at my earliest convenience. Great communication and they were able to diagnose and solve the problem that day and I was back up and running. The main tech was training a new hire, and he was also clearly knowledgeable! They both impressed me, so I felt comfortable signing up for their maintenance package and will continue to use Allegiance in the future! Great local company!"

"Thanks for fixing a bad fan motor, peace and quiet has been restored 👍. Both techs, Mr. Moon and Mr. Renck, were outstanding young men and very professional."

"I highly recommend Allegiance Heating & Air. My furnace did not come on in this seasons first cold snap. In a panic that I was looking at an expensive replacement, I made the call. Allegiance responded quickly. The technician was friendly, professional and thorough. Diagnosis was a simple and inexpensive fix of a thermostat replacement. It is clear that this company puts the needs of their customer first and foremost. They made my day! I will use Allegiance Heating & Air for any future needs."

"Had to get someone professional to look at an AC issue I was having and failed to fix on my own :). Went with Allegiance based on relationships and reviews and I was not disappointed. My technician (Benjamin) was professional and knowledgeable. He was able to address my issue quickly and get me back up and running. He also took time to explain what happened and also things to consider for the future to help me plan and budget. Lastly, their communication was top notch. I got a text telling me when they were on their way and I could even view their location to see how close they were along with a picture of the tech. Super impressed!"

"Garrett was very knowledgeable and took his time throughout the whole process. After having a previous company come out, I wanted a second opinion and I am super glad I did. Garrett looked in our crawl space and attic to ensure our ductwork was up to par. He carefully addressed our situation and provided various options to replace our heat pump and ductwork. He answered all the ridiculous questions I had and did not make me feel rushed. Would highly recommend!"

"My situation is a bit unique. I'm under contract for a home and due to the age of the HVAC system, wanted a thorough inspection. Allegiance was happy to help and even did their best to work the scheduling around the current homeowner's availability. Lucas was my technician and out of the 3-hr window, he arrived at the exact time the homeowner requested. Interactions with the office staff over the phone were very helpful and professional, no matter how many times I called to fine tune the timing. Lucas was also very professional, was thorough and efficient. I also asked quite a few questions and he was very willing to answer all of them patiently and in a very easy to understand way. I will never choose any other company for HVAC needs."

John Knuckles

"We have worked with Allegiance Heating & Air since 2017 when they solved our upstairs cooling issues by adding a zoning system to our HVAC. We’ve had regular maintenance to our system since then by various technicians, but lately Lucas S. has been the tech doing the service calls. He is outstanding. Thorough, efficient, polite, tremendous customer service skills - an absolute pleasure to do business with."

"If I could put 10 stars I would!! Benjamin was awesome! Our AC went out in the middle of the night and was already 77 degrees at 9am. By noon it was 81 degrees in the shop. We have protein bars that can melt if they are not at least room temperature for a period of time. I called Allegiance and they sent somebody out within a couple hours. Benjamin was here for hours. Instead of us having pay a nice penny for a new unit, Benjamin found the problem with the old unit and had us back up and running!! Big shoutout to Allegiance Heating & Air. SupZilla Clarksville appreciates you big time!!"

Julian Domiray

"Lucas was very informative and patient while explaining the fees, terms, etc of installing a new HVAC system. He came out next day to do a tune up after our AC went out and got everything working again. He was super sweet and very professional. Highly recommend Allegiance for your HVAC needs!"
