Ac Repair Done Right, Every Time

Every job starts with a real diagnosis, not a guess — here's the full scope of what our AC repair technicians handle across Hillsborough, CA.

Refrigerant Charge & Leak Repair

Low charge is a symptom, not a diagnosis — we find the leak with electronic detection and UV dye before recharging. Techs handling refrigerant charge & leak repair carry the specific parts and tools this job calls for, not a generic kit.

Condenser Fan Motor Repair

A condenser fan that's stalled or running slow lets head pressure spike, which can trip the compressor's high-pressure safety. This is one of the most requested AC repair calls we get across Hillsborough, CA.

Evaporator Coil Cleaning & Repair

We check for coil frost, which usually points to airflow or charge issues upstream. This is one of the most requested AC repair calls we get across Hillsborough, CA.

Compressor Diagnostics

Hard-starting, humming-but-not-spinning, or tripped breaker symptoms get tested with a start capacitor check before any compressor is condemned. This is one of the most requested AC repair calls we get across Hillsborough, CA.

Thermostat Calibration & Wiring

A miscalibrated or miswired thermostat can mimic a full system failure. Techs handling thermostat calibration & wiring carry the specific parts and tools this job calls for, not a generic kit.

Ductless Mini-Split Diagnostics

Ductless systems fail differently than central air — we service indoor head units, line sets, and outdoor condensers. This is one of the most requested AC repair calls we get across Hillsborough, CA.

Ac Repair FAQ

Why is my AC running but not actually cooling the house?+

A full diagnostic checks all three before we touch the refrigerant charge.

Is ice on my AC unit a serious problem?+

Ice almost always means something is restricting airflow or refrigerant flow, and running it iced up can damage the compressor.

How much refrigerant does my system actually need?+

Every system has a manufacturer-specified charge amount — we don't top off blind, we charge to spec using superheat/subcooling readings.

Can you service older R-22 systems?+

Yes, though R-22 supply is limited and increasingly expensive — we'll be upfront if a repair-versus-replace conversation makes more financial sense.

Do you work on ductless mini-split systems?+

Mini-splits have their own fault-code language, and our techs are trained on the major brands.

How fast can someone reach Hillsborough during peak summer demand?+

Call volume rises with the heat, so arrival windows can extend during heat waves — dispatch gives you a live estimate when you call.
