With Summer in full swing, the last thing you want is an air conditioner that does not blow air. This problem will quickly make your home very uncomfortable, especially during those super hot days. When an air conditioner is not blowing any air this can point to a few different problems. Some of these problems can be easily corrected, while others may require the aid of an HVAC service. Hal Mechanical will share some of the common reasons why an air conditioner may not be blowing any air.
Clogged Air Filter
Your air conditioner’s air filter is designed to catch dust, pollen, and other particles before they enter your system. However, if the filter is not changed regularly, it can become clogged. This not only decreases the quality of your indoor air but can also restrict airflow, preventing your air conditioner from blowing air properly. If it has been a while since you replaced your air filter, this could be the issue. Luckily, it is an easy fix as you simply replace the old filter with a new one.
Frozen Evaporator Coil
The evaporator coil in your air conditioner unit is responsible for cooling the air that flows through the air conditioning system and the entire home. If the coil gets too cold, it can freeze, preventing the air conditioner from blowing air. The most common cause of a frozen evaporator coil is a lack of airflow from a dirty filter or a refrigerant leak. If you suspect or have discovered frozen coils, you should immediately turn off your air conditioner and call a professional to inspect it.
If your air conditioner is not blowing air, the problem could be as simple as a malfunctioning thermostat. The thermostat controls the temperature of your home by signaling your air conditioner when to turn on and off. If the thermostat is not working correctly, it could cause your air conditioner to malfunction. Check to see if your thermostat is set to the correct temperature and is in the “cooling” mode or setting. If this doesn’t solve the issue, you may need a professional to determine the problem.
Air Duct Problems
The ductwork or air duct system in your home directs and distributes the cooled air from your air conditioner. If there is a leak or blockage in the air ducts, it can prevent the air from reaching your living spaces. Signs of air duct problems include uneven cooling in different rooms or areas of the home and a sudden increase in energy bills. Air duct issues should be addressed by a professional HVAC technician to ensure efficient and effective repairs.
Blower Fan Problems
The blower fan in your air conditioner unit moves all of the air through the home. If it is not working properly, it can prevent your air conditioner from blowing air. Common signs of blower fan problems include unusual noises from your air conditioner unit and a circuit breaker that keeps tripping. If you suspect a blower fan problem, it is best to have this issue checked by a professional to prevent further damage to your system and to repair the blower fan.
