  • If your air conditioning unit is blowing warm air, there are a few troubleshooting steps you can take to figure out what the problem might be. Before you call an air conditioning maintenance service in Belleville, IL, check your a/c for these common issues.

    Check Your Thermostat

    Before you call an air conditioning repair expert, it is a good idea to check you haven’t made a mistake in operating the unit. Check the thermostat to ensure it is not set to heat, even if you are sure you set it to cool. Someone else in your household may have changed the setting without you noticing.

    Check the Filter

    Airflow restrictions can stop your air conditioner from cooling air correctly. The most common cause of airflow restrictions is a dirty filter. Depending on the model of your air conditioner, you may be able to remove the filter and remove or replace it yourself. However, if you don’t feel confident performing your own a/c maintenance, you can call a maintenance company to service the unit for you.

    Check the Return Ducts

    As well as checking the filters, you should also check the return duct and any hoses connected to your unit. If the duct is broken or disconnected, the air conditioner may pull in uncooled air and blow it around your home.

    Check the Electrical Supply

    Sometimes, air conditioners blow warm air because the power supply to the outdoor cooling unit has failed. Check the circuit breakers in your home and reset any that have tripped. If your circuit is controlled by a fuse instead of a circuit breaker, check to see if it has blown and replaced it if necessary.

    If your air conditioner keeps tripping the circuit breaker or blowing a fuse on its circuit, you need to call a professional a/c repair service. There may be a serious problem with the a/c unit that is causing it to trip the electricity supply. It is always a good idea to get an a/c maintenance professional to repair electrical problems for you, as they can be dangerous to address.
