What Our Job Records Taught Us About Broken ACs
We track every job in our field software, and our South Bay records say something most homeowners don’t expect: the dramatic failures are rare. Refrigerant problems, failing thermostats, control boards, and blower motors, roughly in that order, cause most of the “my AC is dead” calls we run. Our own customers’ reviews talk about capacitors; the records say boards, motors, and airflow fail more often. That’s why we diagnose before we quote – the obvious guess is frequently wrong.
The visit starts with a $110 diagnostic. Most repairs land between $223 and $2,899 parts and labor – quoted upfront, before work starts. Summer is our peak (June through August books fastest), so if the system is limping in May, call before the first heat wave turns a scheduled repair into an emergency.
5 Signs Your AC Needs Repair
Warm air from the vents
If the system runs but the air isn’t cold, suspect a refrigerant leak, a failed capacitor, or a compressor problem. Running it that way makes the damage worse.
Short cycling
Turning on and off every few minutes overheats components and spikes your bill – often a control board or thermostat fault, two of the most common repairs in our job log.
Grinding, buzzing, or squealing
Healthy systems hum. Mechanical noise usually means a blower motor or bearing on its way out – it’s one of the repairs we see most.
Water or ice on the unit
A frozen coil or pooling water around the air handler points to airflow or drainage trouble. Shut it off and call.
Bills climbing, comfort dropping
A struggling system draws more power to do less. If summer bills jumped without a rate change, the AC is usually why.
