Phoenix Comfort Systems | Experienced HVAC Repair in Belleville, IL

This common issue, known as radiator heating imbalance, often occurs in older Belleville homes. It's usually caused by air trapped in the system, a faulty valve, or sediment buildup. Our technicians perform a thorough system assessment to pinpoint the cause, then bleed the radiators, adjust valves, or flush the system to restore even heat distribution throughout your home.

Yes, refrigerant leaks are a frequent cause of poor cooling performance in our area. Signs include ice on the coils, hissing sounds, and a steady increase in your energy bills. Phoenix Comfort Systems uses advanced electronic leak detectors to find the source quickly. We then repair the leak and recharge the system to the manufacturer's exact specification, ensuring efficient, reliable cooling.

Proactive maintenance is key. We recommend biannual tune-ups—once before summer for your AC and once before winter for your heating system. This allows us to catch small issues, like early signs of refrigerant loss or radiator valve wear, before they become major repairs. Our maintenance plans are designed for local climate challenges, helping extend your system's life and improve efficiency.
