HVAC Repair Union KY | Call Arion Heating and Cooling

The most common sign is your AC running constantly but not cooling your home effectively. You might also notice ice forming on the refrigerant lines or the indoor coil, or a noticeable hissing sound. If you suspect a leak, it's important to call for repair promptly, as low refrigerant forces the system to work harder, increasing energy bills and risking compressor failure.

Not necessarily. Often, a malfunctioning thermostat is a standalone issue—like dead batteries, faulty wiring, or a need for recalibration—that our technicians can repair quickly. We'll diagnose the problem first. A full system replacement is typically only recommended if your HVAC unit is very old, inefficient, and has frequent major repairs, not just because of a thermostat problem.

Our preventative maintenance service is designed to catch small issues before they become big, expensive problems. During a tune-up, we clean components, check refrigerant levels to spot leaks early, test thermostat calibration, and ensure all electrical connections are secure. This proactive care improves efficiency, extends your system's lifespan, and helps prevent those sudden breakdowns during peak summer heat or winter cold.
