    We have been using Weir for our heating and cooling needs for more than 20 years. We lived in O'Fallon, IL for many years and Weir was always our choice for any issues we had. They have always been very responsive, and any work was always done in the most expedient and professional manner. They even completed some work on our outside unit while we were out of town. When we moved to our new home in Marine, IL, we were glad to see that Weir had installed the HVAC units, because we knew they would be dependable. We highly recommend the entire Weir team!

    I highly recommend Weir Heating & Cooling. My grandfather was a contractor for many years and used them on his home builds. I have personally used them now for a few years with a couple HVAC projects. I did a dual zone for my basement and most recently with a new furnace replacement. They have been very efficient, easy to work with and have very reasonable prices.Services: Duct and vent installation
