Need proof of our quality? Don’t take our word for it…

Lost our AC during the hottest week in August..Allegiance promptly took care of replacing our old system! The installers were extremely professional, respectful and very knowledgeable! Very competitive pricing with excellent service!

Christy Lopp AC Repair Service - New Albany, IN

My furnace went out and I had several companies bid the replacement and all were comparable in price. I went with Allegiance because they seemed the most knowledgeable and I felt comfortable with them in my home. They replaced it the very next day and were great! Great experience!

Kate Stinson Furnace Installation Service - New Albany, IN

Allegiance is one of those companies with a well earned stellar reputation. From sizing the right unit for our home through installation and follow up, I cannot imagine a better group of professionals to trust. They took their time in the installation, didn't cut corners, and answered all of my questions very thoroughly. I would strongly recommend Allegiance, whether for installation of a new unit or servicing of existing units.
