Quick checks for AC Not Cooling

✓ Set the thermostat to Cool and a few degrees below room temperature, then wait 10 minutes.
✓ Check the air filter. A clogged filter restricts airflow and is one of the most common causes of weak cooling.
✓ Make sure supply vents and return grilles are open and not blocked by furniture or rugs.
✓ Look at the outdoor unit. Clear leaves and debris, and check that the fan is spinning.
✓ Check the breaker panel for a tripped AC breaker. Reset it once only; if it trips again, stop and call.
✓ Look for ice on the indoor coil or refrigerant lines. If you see ice, turn the system off and let it thaw before calling.

Likely causes

Common causes

A technician needs to confirm the actual cause. These are the usual suspects in Atascocita, Humble, Kingwood and Crosby homes.

✓

Dirty filter or blocked airflow

Restricted airflow keeps the system running without moving enough cool air into the house.

✓

Frozen evaporator coil

Often follows a dirty filter or low airflow. Ice blocks air from passing across the coil.

✓

Low refrigerant or a leak

Refrigerant does not get used up. Low levels mean there is a leak that a technician needs to find.

✓

Failed capacitor or fan motor

If the outdoor fan or compressor will not start, the system hums but does not cool.

✓

Dirty outdoor coil

Heavy dust, cottonwood and grass clippings around the condenser can cut heat rejection in summer.

✓

Undersized or aging system

An older unit may run all day and still fall behind on the hottest Gulf Coast afternoons.

Do not wait

Call right away if…

✓ The outdoor unit is silent or you hear grinding or buzzing.
✓ Water is leaking inside or the breaker keeps tripping.
✓ Ice is covering the lines or the indoor unit.
✓ There is a burning smell. Turn the system off at the thermostat and the breaker.
✓ Someone in the home is elderly, very young, ill or sensitive to heat.
