Our experienced service technicians will walk you through all the details of your water heater repair or installation. Most homes have a 40-gallon or 50-gallon water heater. Larger tanks are generally used in homes that have a hot tub, or with serious hot water demands. We generally recommend swapping an existing tank with an equally-sized new one, but if you consistently run out of hot water, you might consider upgrading to a larger tank. Call Citywide today for your Chicago water heater repair.

Steam heating systems are seldom installed now in small residential buildings but are still common in many older ones. They are simple in design and operation, but require a higher level of maintenance than modern residential heating systems which our techs are fully capable of performing. We offer a large selection of boilers from the top manufacturers in the industry. Feel free to ask an expert HVAC technician here at Citywide and we will help you narrow down a boiler system by fuel type, system type, BTU load, efficiency, to get the best boiler for your business/home.
