πŸ“ San Mateo, CA β€” The AC won't start after winter.
That’s how Jason L described the issue when he contacted us. The system is installed at his parents' home. He said it used to run just fine β€” but this spring, total silence.

πŸ” What we found during diagnosis:
The AC unit is about 17 years old, and over time, the startup current has increased. The installed circuit breaker can’t handle the load anymore β€” it trips every time the system tries to start.

This is a common issue with aging systems.

⚠️ Why it matters:
As compressors wear out, they draw more power to start β€” and that’s a clear warning sign. Replacing the breaker might bring the system back to life, but it’s a temporary fix.
Such behavior usually signals that the system is nearing retirement.

πŸ›  Our solution:
We recommended replacing the breaker with one that can handle the startup load.

πŸ’° Cost: under $500
βœ… 6-month warranty
