If your AC blows warm air off and on, first check the thermostat is set to Cool and the fan to Auto. A clogged filter, blocked vents, or low refrigerant can also cause warm air or poor airflow. We diagnose issues like inaccurate thermostats, moisture/leaks, strange sounds, and odd odors, then repair or replace faulty parts and restore cooling. Annual maintenance helps prevent these problems and keeps warranties intact. We serve Rohnert Park, Novato, and nearby North Bay cities.
Quick checks:
- Set thermostat to Cool; replace batteries.
- Replace dirty air filter.
- Open supply/return vents.
- Look for ice or leaks; don’t run if iced.

AC compressor replacement costs vary by system and the exact problem. We confirm the price on site and give upfront, job-based pricing before work begins. Factors include refrigerant type (new 2025 rules may affect options), unit size and brand, warranty status, labor and access, and whether other parts need repair. We service Novato, Petaluma, San Rafael, and nearby. Free estimates are available, and Lucky’s Comfort Club members receive discounts and priority service.
