Aspen Leaf Mechanical - Westminster's Professional HVAC Repair

Common signs include your AC blowing warm air, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing sound from the indoor unit, and a sudden spike in your energy bills. If you notice any of these, it's best to call for professional diagnostics, as low refrigerant can damage the compressor and reduce efficiency.

First, check that your thermostat is set to 'cool' and the temperature setting is below the room temperature. Ensure the circuit breaker for the outdoor unit hasn't tripped. If these are fine, the issue could be a failed capacitor, a wiring problem, or the compressor itself. Avoid repeated attempts to start it, as this can cause further damage, and contact a professional for a safe and accurate diagnosis.

Regular professional maintenance, like our tune-up services, is crucial. It involves cleaning coils, checking refrigerant levels, inspecting electrical components, and lubricating moving parts. This proactive care can identify small issues like minor leaks or capacitor wear before they lead to a major compressor failure, improving reliability, efficiency, and lifespan, especially during our hot summers and cold winters.
