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.

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!
