There are few things worse than an air conditioner that stops blowing cold air in Los Banos, CA. With daytime temperatures exceeding 90 degrees Fahrenheit from June through September, the last thing you want is an AC malfunction. Read on to find out three reasons why your air conditioner isn’t blowing cold air and what you can do about each of them.
Dirty Air Filter or Coil
Dirty air filters cause all sorts of problems for air conditioners, including a lack of cool air. When the filter’s pores are obstructed, the air handler can’t blow the cool, dehumidified air through it. Check the filter monthly, and replace it as soon as it’s dirty. At a minimum, put in a new filter every two months. Air conditioners also have indoor and outdoor coils. If the coils get dirty, they can’t absorb or release heat. An annual tune-up keeps the coils clean.
Improper Thermostat Setting
If there’s no cold air coming from your home’s vents, check the thermostat setting. Make sure the fan is set to auto and the system is set to cool. If you have a programmable thermostat, check its battery. A low battery charge could cause the thermostat to lose its settings. For smart thermostats, make sure it’s connected to your Wi-Fi. If your thermostat won’t respond, it may need to be replaced.
Refrigerant Leak
According to the Department of Energy, a refrigerant leak could also prevent the air conditioner from blowing cold air. A loss of refrigerant reduces the air conditioner’s ability to absorb heat and remove humidity from your home. A refrigerant leak requires a prompt air conditioning repair by a certified technician. The technician will measure the refrigerant charge, identify the source of the leak, repair it and recharge the refrigerant to the correct pressure level.
