Common AC problems we diagnose

Cooling problems can have similar symptoms but very different causes. We inspect the system and test the relevant components before recommending a repair.

Safe checks before you call

You may be able to rule out a simple issue without opening the equipment. Confirm the thermostat is set to Cool, lower the set temperature, and set the fan to Auto. Check whether the air filter is heavily clogged and make sure return grilles and supply vents are open.

If the HVAC breaker is tripped, reset it only once. If it trips again, leave it off and request service. Repeatedly resetting a breaker may be unsafe. Do not open electrical panels, touch refrigerant lines, or reach through the outdoor fan guard.

When to turn the AC off

Switch the system off at the thermostat and call for help if you smell burning, see smoke, hear grinding or harsh electrical buzzing, find ice on the refrigerant line, notice water reaching electrical components, or the breaker trips repeatedly. Continuing to operate damaged equipment may increase the repair cost or create a safety risk.

If extreme indoor heat is affecting an infant, older adult, or anyone with a medical condition, move to a cooler location while service is arranged. Call emergency services in a life-threatening situation.

Our emergency AC repair process

  1. Listen to the symptoms. We ask what the system is doing, when the problem started, and whether you noticed ice, water, noise, odors, or a tripped breaker.
  2. Inspect and test. The technician evaluates airflow, thermostat operation, electrical components, motors, coils, drainage, refrigerant performance, and other relevant parts of the system.
  3. Explain the findings. You receive a clear explanation of the problem and the available repair options before work proceeds.
  4. Repair and verify. After the approved repair, the technician checks system operation and cooling performance.

Repair or replace the air conditioner?

Many cooling failures can be repaired. Replacement may deserve consideration when the system needs frequent repairs, has a failed major component, uses difficult-to-source refrigerant, no longer cools the home evenly, or has become unreliable during peak heat.

The right decision depends on the diagnosis, repair cost, overall equipment condition, comfort, efficiency, warranty coverage, and your plans for the property. We explain both options when replacement is a reasonable alternative. Learn more about AC replacement and air conditioning installation.

Why timely AC repair matters

A small electrical, airflow, or drainage problem can place extra strain on other components. Early diagnosis may prevent additional damage, reduce water risk, and restore comfort faster. It also helps you decide whether a repair is a sound investment before the system fails completely.

Help prevent the next breakdown

Replace filters as needed, keep the outdoor unit clear of loose debris, and pay attention to changes in airflow, sound, cycle length, and energy use. A seasonal inspection can identify worn electrical parts, dirty coils, drainage trouble, and other developing issues before the hottest part of summer.

Frequently asked questions

Do you provide AC repair at night and on weekends?

Our regular service hours are daily, 7:00 AM to 5:00 PM. Emergency calls are accepted 24/7; technician visits depend on current availability. Call 916.666.0074 to describe the issue and check current technician availability.

Why is my AC running but not cooling?

Possible causes include an incorrect thermostat setting, clogged filter, frozen coil, outdoor-unit power problem, failed electrical component, dirty coil, blower trouble, or a refrigerant issue. Testing is the safest way to identify the actual cause.

Should I turn off an AC that has ice on it?

Yes. Turn cooling off and let the ice thaw naturally. Do not chip or scrape it away. Restricted airflow, a blower problem, coil trouble, or a refrigerant issue may be responsible and should be diagnosed before normal operation resumes.

Can I reset the AC breaker?

You may reset a tripped breaker once. If it trips again, leave it off and call a technician. Repeated trips indicate a problem that needs testing.
