Navan HV/AC - Country Club Hills's Expert HVAC Repair

This is a common issue we see locally. Often, it's due to incorrect wiring during installation, a tripped breaker, Wi-Fi signal problems, or outdated firmware. Our technicians will first verify the wiring at your furnace and thermostat, check your home's Wi-Fi strength, and perform a full system diagnostic to ensure the thermostat is correctly communicating with your HVAC equipment for reliable performance.

Yes, a clogged condensate drain line is a very frequent cause of AC leaks for homeowners in our humid Illinois climate. Algae and mold buildup inside the PVC pipe blocks the water from draining. We safely clear the clog using specialized tools, flush the line with a sanitizing solution to prevent regrowth, and often install a safety float switch to automatically shut the system off if a future clog occurs, preventing water damage to your home.

Our preventative maintenance is designed to catch small issues before they become big problems, like the ones you mentioned. For your cooling system, we thoroughly clean the condensate drain line, check refrigerant levels, clean coils, inspect electrical connections, and calibrate your thermostat. For heating, we check heat exchangers, burners, and safety controls. This proactive care improves efficiency, prevents unexpected breakdowns, and extends the life of your system.
