HVAC Services Orland Park IL | Call Family Heating & Air Conditioning

Thermostat malfunctions are common here and can stem from electrical issues, aging components, or even dust buildup. An inaccurate or unresponsive thermostat forces your system to work inefficiently. We'll diagnose the root cause—whether it's a faulty sensor, wiring problem, or simply time for an upgrade to a more reliable, programmable model—to restore precise control and comfort to your home.

Key signs include your AC blowing warm air, ice forming on the refrigerant lines or evaporator coil, and a noticeable hissing sound. Refrigerant leaks are a serious issue because your system can't cool properly without the correct charge, leading to higher energy bills and potential compressor failure. We use specialized tools to locate and seal the leak, then safely recharge the system to its factory specifications.

Staying proactive helps! Regularly replace your air filter (every 1-3 months), keep outdoor units clear of debris like leaves and grass clippings, and ensure vents inside aren't blocked by furniture. If you notice uneven cooling, strange noises, or a sudden spike in your energy bill, don't wait—these can be early warnings of the thermostat or refrigerant issues we often see. Giving us a call early can prevent a minor issue from becoming a major repair.
