The last thing you want on a sweltering North Carolina summer day is your air conditioner running but not chilling. Do not panic if your AC is on and not producing cold air; this is a common issue with usually has a fix. Sometimes the fix is easy—just changing a setting or replacing a filter—and other times you will need the advice of a professional. Let’s review a few typical causes your AC might be blowing warm air and how to get cool air back with air conditioning repair services in NC.
1. Problems with Thermostat or Power
Start with the simplest possible fix—that of your thermostat or power source. Make sure your thermostat is set to “Cool,” with a temperature below the room temperature right now. It should also be on “Auto,” rather than “On,” since otherwise the fan might run air that isn’t cooled. Then, examine the electrical panel in your house. Sometimes, the summer storms or power surges in North Carolina trip the AC circuit breaker, so power is cut off. If your thermostat runs on batteries, make sure they are not dead.
Solution: Fix any thermostat settings; replace batteries if necessary; then, reset any tripped breakers. See a professional whether the breaker trips once more or the AC still won’t cool.
2. Stuck Air Filter Preventing Airflow
A dirty air filter is one of the most common offenders for an AC failing to blow cold air. A blocked filter chokes off airflow, so it limits the amount of cool air your AC can move. Very low airflow can cause the indoor coil to freeze, depriving the air of its cooling effect.
Solution: Check your HVAC filter and replace it if it is dirty, given North Carolina’s pollen and dust. Summertime expectations would not hold here. You might need a new filter every month in hot NC months. Your AC will blow colder air right away if you restore appropriate airflow with a clean filter.
3. Low Refrigerant: Possible Leak
To chill your house, your air conditioner absorbs heat using refrigerant, a specific coolant. Usually resulting from a leak, a low refrigerant level will cause the AC to struggle to cool and may only blow lukewarm air. It might even run continuously without ever approaching the target temperature. Often, a refrigerant leak can be indicated by a faint hiss or bubbling sound close to the unit.
Solution: Refrigerant problems call for a licensed HVAC technician doing air Conditioning Repair in NC. Call a professional who can locate and fix a suspected leak or low refrigerant, to then properly recharge the system. Refrigerant should not be added by you. Your AC should blast cold air once the leak has been repaired and the system is recharged.
4. Broken Outdoor Unit or Compressor
If the indoor blower is running, yet you still feel no cold air, the outdoor unit may be the cause. Look at the outside of your condenser unit. If it does not run at all, or you hear clicking or humming, but the compressor or fan motor fails to fully turn on, there may be a failed capacitor or a bad transformer. The AC won’t create cold air if the compressor isn’t performing as it should. After years of use, particularly in North Carolina during severe summer heat waves, components like these can fail.
Solution: First, ensure the outdoor unit has breathing room and is free of trash. You will need to call NC’s air conditioning repair if it is clean but not running (or producing odd sounds). A technician can ascertain whether the compressor can be fixed or replace malfunctioning components such as a fan motor or capacitor. Should your AC be older and show a significant failure, they can counsel on whether it would be more prudent to replace or repair the appliance.
