As the temperatures rise, the last thing you want is your air conditioner blowing warm air. It defies the purpose of having an air conditioning system at all and can make your home unbearable to live in.
So, why is your AC blowing hot air? Below, we will explore some of the major reasons for this problem and what can be done to prevent them.
Dirty Air Filters
One of the potential reasons why your AC is blowing hot air is dirty air filters. Air conditioners work by pulling air from outside, cooling it down, and then blowing it back into your living space. When the air filters are clogged, the flow of air is restricted, making the system work harder to cool your home or office. Reduced airflow will cause the evaporator coils to freeze up, leading to the air conditioner blowing warm air. To fix the problem, all you need to do is replace the dirty air filters; it is that simple.
Another potential reason why your AC is blowing hot air is an issue with your thermostat settings. Before you call in an HVAC professional, check if your thermostat settings are set to “cool” mode. Also, ensure that the settings are set to “auto” and not to the “fan” mode. It could also be that the temperature setting is too high, making the AC blow warm air, or if the thermostat is set too low (lower than 69), it can cause the system to freeze.
Adjusting the thermostat settings could be an easy solution. If not, it may be your thermostat. Your HVAC professional can easily assess this issue and replace it if necessary.
Frozen Evaporator Coils
Sometimes, air conditioners can freeze up if there isn’t enough airflow, if there is a refrigerant leak, or even if the thermostat is set too low. When the evaporator coils freeze up, the AC system will blow warm air. An HVAC professional will ask you to turn off your unit to allow the ice to melt and then come check for any refrigerant leaks. It is essential to get the coils thawed out as soon as possible, as the longer they remain frozen, the higher the chances are of your AC failing altogether.
Clogged Condenser Coil
Another possible reason why your AC is blowing hot air could be clogged condenser coils. The condenser coil is responsible for releasing the heat that the AC unit has absorbed from your home. Over time, the coils accumulate dust and debris, making it harder for them to release heat. This, in turn, causes the system to overheat and blow warm air. You can clean the condenser coils yourself, but it’s recommended that you call in an HVAC professional to do it thoroughly.
Low Refrigerant Levels
Have you found your air conditioner blowing warm air but have checked the air filter, thermostat setting, and coils? A lack of refrigerant may be to blame.
Refrigerant is what helps cool the air in your home or office. If the refrigerant levels are low, your AC won’t work efficiently. Low refrigerant levels can be caused by leaks in the refrigerant lines or small amounts being released over time during maintenance. An HVAC professional can determine the cause and adjust to the proper level. Whatever the case, don’t hesitate to call our experts for an AC repair in Jackson, MS.
