HVAC Services Oakley CA | Call Stevenson Mechanical

In Oakley's climate, with its dust and seasonal temperature swings, we generally recommend checking and likely replacing standard 1-inch air filters every 1-3 months, especially during high-use seasons like summer. A clogged filter forces your system to work harder, increasing energy bills and strain. Our technicians can assess your specific system and home environment during a tune-up to recommend the perfect maintenance schedule for you.

Key signs your AC may be losing refrigerant include reduced cooling power (air isn't as cold), longer run times, ice forming on the refrigerant lines or evaporator coil, and a noticeable hissing or bubbling sound from the unit. Since refrigerant doesn't get 'used up,' a low level always indicates a leak that needs professional repair. Our experts use specialized tools to locate and seal leaks, then recharge your system to the manufacturer's exact specifications.
