What affects the price

Older systems may require more complex troubleshooting or hard-to-find components, which can influence the final bill. Exact pricing confirmed free on the call.

If those are fine, turn the system off to prevent further damage and call us. We can arrange for a licensed pro to come out quickly and diagnose the issue.
How often should I get my AC unit serviced?
For optimal performance and to prevent breakdowns, it's recommended to have your AC unit serviced at least once a year in San Mateo. Ideally, schedule this maintenance before the peak cooling season begins. Regular tune-ups help catch minor issues before they become costly repairs and ensure your system runs efficiently.
When should I consider replacing my AC instead of repairing it?

If your unit is over 10-15 years old, or if it's no longer cooling effectively and energy bills are rising, replacement might be more economical.
