We had a complete HVAC system and a hot water heater installed. The guys were professional, well mannered, and completed the work in a timely manner. Would definitely use them again.





I was nervous at first because my AC broke in the middle of 80 degree weather which is strange for April, but Allegiance Heating and Air was incredibly prompt and professional. The technician arrived within an hour, explained the problem clearly, and completed the repair. The technician , Mr. Garrett Moon was a very nice and courteous young man. He found the problem and fixed it within a timely manner. I highly recommend them for any heating or cooling needs. I’ll definitely give them a call again should I ever have another issue, but hopefully not. Knock on wood 😁. Give them a call… you won’t be disappointed!





From the moment I called to schedule a service, the team was quick to respond and arrived right on time. The technician was professional, friendly, and clearly knowledgeable about my heating system. He explained the repair options in plain language and completed the job efficiently. I appreciated the reliable service and the fact that the work was done the same day. I would definitely recommend Allegiance Heating and Air for any residential HVAC needs.





5/5 stars – I was very impressed with the efficient, affordable and timely service from Allegiance Heating and Air. The technician arrived on time, and performed the service quickly, no repairs needed at this time. Communication was clear and the whole experience felt hassle‑free. I would definitely recommend them for any residential HVAC needs.





Knowledgeable, experienced individual.
Explains Allegiance Heating and Air was incredibly reliable, professional and affordable. They arrived right on time, kept the work area clean and finished the furnace repair quickly. The technician explained everything clearly and the price was a great value. If happiness had a location on Google Maps, it would be here.
Gilbert had to go above and beyond because York is no longer making the part for my furnace. But he was able to find a way to construct a housing bracket for my furnace. Ingenuity, determination and integrity is what finally got my furnace fixed. Gilbert is truly a one of a kind technician.
Thank you for always going the extra mile. Gilbert is always respectful and helpful with any concerns.





"Great service, most knowledgeable and capable HVAC business in Kentuckiana!! Pete Flemming and Bryan the owner, are HVAC encyclopedias. They have the highest integrity of any HVAC business I have ever used. Allegiance has put numerous units in for me over the last 17 years. I will continue to use and trust them."





"Fast response from Allegiance when our heat was out on New Year’s day! Service technician was friendly and efficient. He took the time to explain the problem, tell us about the temporary fix and the plan for permanent repair. We were impressed!"





"Love Allegiance! Their technicians, in particular Benjamin, explain everything. Fast and thorough. A/C was out on a Sunday. Called Allegiance and within a few hours Benjamin arrived. Such a comfort as he was the one who last serviced our units. He quickly replaced part and cooling is restored!"





"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."





"Right on time :) respectful, fast, and polite. Even gave my fur babies some attention."





"Had Garrett out today to fix our AC. Fantastic tech. He showed up exactly when he said he would and kept us informed of what he was checking and what he found. Highly recommend!"





"Lucas with Allegiance showed up on time as promised, was professional and extremely patient and responsive with all my questions. He took care of the issue, and I feel he was trustworthy! He had us back to cool and comfortable on one of the hottest days of the year."





"Lucas did a great job! Very professional and expedient. Explained the process very well and represented Allegiance as a truly professional and reputable company."





"Arrived on time and work diligently to fix issue. These guy are great. Worked quickly to resolve my issues."





"Lucas was great - he spent a lot of time trying to figure out what was going on and explained everything he was doing. I trust Allegiance and wouldn’t want anyone else working on/in my house!!"
