Our Services Include:

Installation and Replacement of Old Heating Systems

Your monthly energy bills are probably higher than they should be if your unit is outdated. In addition, you might have to deal with noisy cycles, inconsistent temperatures, and costly repair calls. In many cases, these older units can't keep up with today’s energy standards.

We install high-efficiency furnaces, boilers, and heat pumps for residential homes, multi-family units, and small businesses. We'll assist you in selecting the best option for your space and budget, whether you're upgrading your gas or electric furnace, moving to a hybrid system, or a heat pump.

Repairs That Keep You Warm Without the Wait

Safety hazards like carbon monoxide leaks or complete system failure can result from putting off repairs or using unlicensed contractors. Many of the clients we serve tell us that they waited too long and that the cost doubled as a result. Many people wait too long, and it ends up costing double.

At Citywide Heating & Cooling, we provide reliable furnace repair in St. Louis and surrounding areas. We service all major brands and models, gas, electric, or oil. Our heating systems technicians are well-trained and equipped with the necessary parts to fix any issue, whether it's a malfunctioning limit switch, a broken heat exchanger, or a malfunctioning ignitor.
