"Leiber is a great company, they operate the old school way. They do a good days work for reasonable pay. They make their appointments on time and on the rare occasion they are running behind they call. I run the maintenance department for a school and church. So I have had the opportunity to use them on a regular basis. Professional and honest is how I would describe the owner."

"My wife and I can't say enough good about our experience with Leiber. Our furnace went out and our neighbor recommended Leiber to us. They are professional, personable, and cost effective. My family is nice and warm this evening because of their ability to fit us in this week!"

Karl and his team are fair, honest, and truly care about their customers and their community. Not only have we used them for many years for our HVAC needs, we enjoy their annual 4th of July parade parties too!
