Why Is My AC Blowing Warm Air

California weather may be considered mild, but we know that it hits triple digits in Fresno. If your AC is blowing hot air it can present a major problem during the summer months. Here are a few reasons why your AC isn’t blowing the cool, refreshing air you need it to on a hot day.

Dirty Conditions

The most common reason for an AC not cooling is that the system is dirty. If your air filter or condenser unit is dirty, the debris will keep cool air from reaching you in the house. You can help prevent this by checking your air filter regularly and having an AC tune-up twice a year.

Thermostat Settings

Sometimes, the cause of an AC problem is as simple as having the thermostat on the wrong setting. If your AC is blowing hot air, make sure that the fan is set to auto instead of on and the system is set to cool before you call the AC company.

Low Refrigerant

It’s relatively common for an AC to blow warm air because of low refrigerant levels, but the problem does require calling a professional for air conditioning repair. Because low refrigerant levels are usually caused by leaks, only a technician can diagnose the problem and repair your AC. If you suspect refrigerant levels may be the cause of your improperly cooling AC, call Lee’s Air Conditioning and Plumbing immediately.

Electrical Problems

Improper cooling can be an electrical problem as well, caused by a loss of power to your outside AC unit. Check the circuit breaker and the emergency shutoff switch to test this theory. If you have to check the breaker often, however, having a professional assess your home for electrical problems is the best plan of action.
