Gibbs Heating and Air Conditioning - Petaluma's Certified HVAC Repair

This is a common issue in our area, often due to older home wiring, Wi-Fi signal interference from our local geography, or firmware that needs updating. Our technicians can diagnose the specific cause—whether it's a wiring issue at the thermostat, a problem with your home's C-wire, or a system compatibility problem—and provide a reliable fix to restore full functionality and control of your home's climate.

Key signs include your AC blowing warm air, ice forming on the refrigerant lines or outdoor unit, a noticeable hissing sound, or a sudden spike in your energy bills. We'll perform a precise leak detection test to locate the source. Our repair involves sealing the leak, conducting a thorough system evacuation to remove moisture and air, and then recharging the system with the correct, EPA-approved refrigerant to restore cooling performance and efficiency.

Proactive maintenance is key. We recommend a bi-annual professional tune-up—once before cooling season and once before heating season. This allows us to check refrigerant levels, test electrical connections, clean coils, calibrate your thermostat, and identify small issues before they become major repairs. For DIY care, regularly replace your air filters and keep the area around your outdoor unit clear of debris to ensure proper airflow and system longevity.
