Since 1983, Weir Heating and Cooling has been providing quality HVAC services to communities across Illinois and Missouri. Our team of technicians and professional staff cares for all of your heating, cooling and ventilation repair and installation needs.

For more than 30 years, Weir Heating and Cooling has been serviced the Missouri and Illinois Bi-State area.

All of our staff members place the customers’ desires at the forefront and go the extra mile when it comes to service. We strive to be timely and leave our customers well-informed about their new or repaired system.

Our material is of the highest quality. We never shortchange the customer by using products that will breakdown shortly after being installed. Weir Heating and Cooling offers a warranty that dispatches a service technician to your residence or business in the event that an installation or repair goes wrong. We value your trust and would never betray it by being unresponsive in times of need. Such dedication is what we believe sets us apart from the competition.
