Air conditioners, heat pumps and furnaces in Chino Hills tract homes, hillside houses and townhomes. We find the fault, tell you what it costs to fix before we start, and fix it — or tell you honestly when replacing makes more sense.

A repair visit

What happens when we arrive.

A repair should not be a mystery. Every visit follows the same four steps, whether it is a house in Butterfield Ranch or a rooftop unit above a restaurant.

1 · Listen
What it did, when it started, what you already checked.
2 · Test
Electrical parts, refrigerant pressures, airflow and drains.
3 · Explain
The fault, the fix and the price — before any work starts.
4 · Fix and check
Repaired, then run and measured before we leave.

Questions

Asked on the phone.

My AC stopped. What should I check first?

The thermostat mode and setting, the breakers and the outdoor disconnect, the filter, water under the indoor unit, and ice on the pipes. Our five-check page walks through each one safely.

A breaker keeps tripping. Can I keep resetting it?

No. Reset it once. If it trips again, leave it off and call us, because something in the system is drawing too much current.

Do you tell me the price before the repair?

Yes. We find the fault, explain it and price the repair before any work starts. You decide whether to go ahead.

Do you work on rooftop units for businesses?

Yes. Retail centres, restaurants, offices and clinics, with work planned around trading hours.
