Moore Heating & Air Conditioning: Expert HVAC Repair Serving Harrisburg, IL 62946

Frozen coils or components are often caused by restricted airflow, low refrigerant, or a malfunctioning blower. Our humid Southern Illinois summers make AC units work extra hard, which can lead to this issue. First, turn the system off to let it thaw completely to prevent damage. Then, check your air filter and replace it if dirty, as this is a common culprit. For a permanent fix, call us. Our technicians will diagnose the root cause, whether it's a refrigerant leak or an electrical problem, and repair it to ensure your system runs efficiently.

It can be tricky to tell! A thermostat malfunction in Harrisburg can mimic many HVAC problems. Start by checking the basics: ensure it has power (dead batteries are a frequent issue), is set to the correct mode (heat/cool), and that the temperature setting is accurate. If problems persist, like the system not turning on or short cycling, it could be faulty wiring, a sensor issue, or a problem with the HVAC unit itself. Our expert technicians can quickly test both your thermostat and system to pinpoint the exact cause and get your home back to a comfortable temperature.

Proactive maintenance is key to avoiding breakdowns during our hot summers and cold winters. We recommend scheduling a professional tune-up twice a year—in spring for your AC and fall for your heater. This allows us to clean components, check refrigerant levels, test electrical connections, and catch small issues before they become major repairs. Regularly changing your air filter (every 1-3 months) is the most important thing you can do yourself to maintain airflow and efficiency. It's a simple habit that protects your system and your wallet.
