Frozen coils are often caused by restricted airflow from dirty filters, low refrigerant, or a failing blower motor—issues that can worsen with our local humidity. We first safely thaw the system, then perform a comprehensive diagnostic to find and fix the root cause, whether it's a leak, a blockage, or an electrical issue, to prevent it from happening again.

Inconsistent temperatures are a frequent sign of thermostat malfunction, which can be due to aging units, wiring problems, or incorrect calibration. We'll test your thermostat's accuracy and check its connection to the system. Often, a recalibration, wiring repair, or a modern thermostat upgrade solves the problem and improves your home's comfort and efficiency.

Our thorough diagnostic service checks all critical components: we measure refrigerant levels, inspect electrical connections, test the compressor and capacitors, assess airflow at the coils and vents, and evaluate thermostat performance. This allows us to pinpoint the exact issue—whether it's a frozen coil, a faulty sensor, or another problem—and provide you with a clear, upfront repair plan.
