If your San Marcos, Texas, air conditioner is malfunctioning, there are several components to check to identify the reason. Many problems can be solved by homeowners. However, some must be diagnosed and rectified by a heating, ventilation and air conditioning expert. The professionals at Del’s Heating & Air Conditioning are NATE-certified and undergo continuous training to properly diagnosis common AC repairs.

Unit Will Not Turn On

There are many reasons an AC will not turn on. First, check the circuit breaker. If it is on, check thermostat settings. If settings are fine, look at the filter. Clogged filters are the primary reason for HVAC malfunction. Clean or change the filter according to the manufacturer’s instructions. If the unit still will not come on, call a professional for AC repairs.

Blowing Warm Air

There are several reasons that ACs blow warm air. Dirty filters affect airflow, critical for proper heat exchange. If dirt coats coils, they cannot function properly. Keep registers clean to allow air to flow into the living space. Trim vegetation around the outside compressor and clean the housing. If the unit still does not cool, a certified HVAC technician should diagnose the problem.

Inconsistent Temperatures

Fluctuating temperatures can be caused by refrigerant leaks, blocked registers, improper thermostat settings, problems with the coils or other sensitive components. Homeowners should make sure furniture and curtains do not block registers. Check the thermostat to make sure temperature and fan settings are correct. However, refrigerant leaks and problems with coils, capacitors or electrical relays should be handled by trained technicians.
