My Alton, Illinois Home AC is Blowing Warm Air. What Do I Do?

AC Broken

During the summer in Alton, Illinois, it is always a good feeling when you can turn on your air conditioning. Around here, AC is a vital part of summer as temperatures can get into the 100s. But, on that rare occasion that you turn on your air conditioning and you feel warm air coming out, what do you do? Here we have listed some common problems that can cause your unit to blow out warm and how they can be solved.

AC Repair

Problems with the Thermostat

One of the most common problems, when your air conditioning is blowing warm air, is there a problem with the thermostat. This is a very simple and easy fix, and it starts with simply turning it off and on again. If nothing changes when you do this, call us and we can send a technician to come to check it out. They will be able to check out your thermostat and let you know if it is time for an upgrade or a replacement.

Low Refrigerant Levels

An essential part of your AC unit is the refrigerant. This is what helps absorbs heat to make sure your air is cool and crisp. When the refrigerant is low, this can cause the condenser to lose its ability to cool any of the air that comes through. The low level of refrigerant can be a sign that there is a malfunction or a leak in the system. A key sign of low refrigerant levels is ice forming outside of the condenser. If your refrigerant levels are low, contact a professional HVAC technician immediately. This substance is very toxic and should only be handled by professionals.

Dirty Evaporator Coils

Fun Fact: inside every air conditioning system are two sets of coils. The first set is the evaporator coils, and these coils pick up heat from the inside. These coils sit relatively close to the air filter. If the filter is not clean, this can cause the evaporator coil to get dirty as well. If your evaporator coils become dirty, this could cause an issue with your airflow. This issue would not allow cold air to get into your Alton, IL home and instead would push warm air in.

Dirty Condenser Coil

AC Repair

The second set of coils is the condenser coils. These coils sit on the outside of the AC unit and are used for releasing warm air that has been collected back into the outside environment. Just like the evaporator coil, the condenser coil can easily become damaged or blocked by debris. Any issues with this coil also can cause warm air to come out of your AC Unit. If you believe that your condenser coil is dirty or blocked by debris, make sure you first turn off your unit. Then inspect everything first to see if there is damage. If there is any larger debris, it should be easy to remove. However, if there is smaller debris that requires a professional technician to clean, give us at Dixon Heating & Air a call.

Electrical Problems

AC systems require a ton of power. Something that can cause your unit to start to blow warm air would be if your circuit breaker is malfunctioning or is off. On occasion, if too much power is demanded, the circuit breaker shuts itself off. If this is the situation you are in, all you need to do is turn off, then turn on your circuit breaker. If this issue keeps occurring, there could be a larger electrical issue that you may need to deal with.
