J S Hvac Refrigeration: Certified HVAC Services Serving Melrose Park, IL 60160

This is a common issue in our area, often due to aging wiring, dust accumulation, or calibration drift. First, check if the batteries are low and ensure it's set to "heat." If the problem persists, it's best to call a professional. Our technicians can diagnose whether it needs a simple recalibration, cleaning, or a replacement with a modern, more reliable model suited for Melrose Park's climate.

This heating imbalance is a frequent call we get in Melrose Park. It's typically caused by air trapped in the radiators (requiring bleeding), a faulty zone valve, or uneven water pressure in the system. Our expert HVAC technicians can perform a thorough system assessment, bleed your radiators to restore proper circulation, and balance the entire system to ensure even, comfortable heat in every room.

Beyond uneven heat or thermostat issues, listen for unusual banging or gurgling noises from your radiators or boiler, or notice a sudden increase in your energy bills. These are signs of underlying issues like sediment buildup, failing pumps, or pressure problems. Our preventative maintenance service is designed to catch these problems early, improving efficiency and preventing costly breakdowns during our coldest months.
