JR Heating & Air Conditioning Co. | Trusted HVAC Repair in Chicago, IL

Uneven heating and cooling is a frequent challenge in Chicago's diverse housing stock, often caused by aging ductwork, improper system sizing, or zoning issues. Our technicians are experienced in diagnosing the root cause, whether it's sealing leaky ducts, rebalancing your system, or discussing solutions like zoning controls to direct air where it's needed most in your specific home.

No, we do not. We understand that a broken furnace in a Chicago winter or a failed AC during a summer heatwave can't wait. That's why our 24/7 emergency service is offered at our standard rate, with no extra fees for after-hours, weekend, or holiday calls. Our goal is to restore your comfort as quickly and fairly as possible.

Our maintenance service is designed to keep your system running efficiently and to catch small issues before they become big problems. A typical visit includes cleaning critical components, checking refrigerant levels, inspecting electrical connections, testing system controls, and ensuring safe operation. For systems over 10 years old, common in many Chicago homes, we pay special attention to wear and tear to help extend its reliable life.
