Tampa’s summers are hot and humid, so if your AC is not producing cold air, you may quickly become uncomfortable. There are several reasons that this could occur. In this guide, we are going to examine the top six reasons your air conditioner is blowing warm air.
1. Wrong Thermostat Setting
An AC unit has several thermostat settings that could prevent the air from cooling. The “auto” setting will automatically adjust the air temperature, so when it is cool in the home, the unit may not be as efficient. It’s best to use the “cool” setting to ensure that the system releases cold air. In addition, the “fan” setting will continue to circulate air, but it will not cool it.
2. Dirty Air Filter
Dirty air filters are one of the most common reasons for warm air coming from your cooling unit. Clogs in your air filter reduce airflow, so it’s important to clean your filters occasionally to optimize efficiency. Change your air filter four times a year or every three months. If you have pets sharing your living space, filter replacement may need to occur more frequently due to pet dander.
3. Refrigerant Leak
The refrigerant cools the conditioned air, so if the unit is leaking or there is not enough refrigerant in the AC, cooling may not occur. Using too little refrigerant ensures that the unit does not stay cold because it cannot absorb heat. If warm air results from a leak, call a professional to check the levels, make repairs, and refill the refrigerant.
4. Frozen Evaporator Coil
Cold evaporator coils have trouble cooling the air that flows through the air conditioning unit. A frozen coil does not receive proper airflow, making it less effective.
5. Compressor Malfunctioning
The compressor is specifically responsible for turning the refrigerant from gas to liquid. If this is not done, the air is not properly compressed, and the cooling cycle will not complete. This makes the air coming out of the vents not as cool and efficient as it could be. The compressor is vital, so if you hear any strange, loud noises coming from your cooling system, there’s the potential for an issue.
6. Duct Leaks
When your ducts are leaking, there is a chance that conditioned air is escaping and warm air is entering the ductwork. This mixture of air in the vents keeps the unit from effectively cooling.
