It’s a blistering summer day in Clark County, and your AC is blowing warm air. Ugh! Before you panic, let’s explore some common reasons why your HVAC system might be malfunctioning and provide troubleshooting tips to help you restore cool comfort to your home.

Common Culprits Behind Warm Air Woes

Several factors can cause your AC to blow warm air. Here are some usual suspects:

Thermostat Troubles: A malfunctioning thermostat can send incorrect signals to your HVAC system. Check the settings and batteries to make sure it’s working correctly.

Air Filter Fiasco: A dirty or clogged air filter restricts airflow, reducing your AC’s efficiency. Replace your air filter regularly, especially during peak cooling seasons.

Refrigerant Leaks: Refrigerant is the lifeblood of your AC system. Leaks can cause a significant drop in cooling capacity. If you suspect a leak, contact a qualified HVAC technician for repair.

Frozen Evaporator Coils: The evaporator coils absorb heat from the air. If they freeze over, airflow is blocked, and warm air is blown instead. This can be caused by a dirty air filter, low refrigerant, or other issues.

Electrical Gremlins: Electrical problems, such as faulty wiring or a malfunctioning blower motor, can also cause your AC to blow warm air.

Troubleshooting Tips for DIYers

Before calling for professional help, try these troubleshooting steps:

Checking the thermostat to verify it’s set to “cool” and the temperature is set lower than the current room temperature.

A fresh air filter can make a difference in airflow and cooling efficiency.

Inspect outdoor unit: Make sure the outdoor unit is clean and free of debris. Clear any obstructions around the unit that could be blocking airflow.

If your AC isn’t turning on at all, check the circuit breaker to make sure it hasn’t tripped.
