Why is My Home Air Conditioner Blowing Warm Air?
Why is my AC blowing hot air? Well, there are plenty of things that can make your A/C blow hot air instead of cool air. You home A/C is made of many parts that must work properly to enable it to cool your home effectively. If one part of your AC malfunctions, it will not be possible for it to cool air effectively. When you discover that your A/C is blowing hot air, it’s highly likely that one or more parts are not functioning as they should. Here are the most common reasons why your home AC cools then blows warm air:
The AC Unit Is Frozen
Did you know that your air conditioner can freeze? Yes, a block or blocks of ice can form inside your AC unit. When a block of ice forms inside the evaporator coil, it becomes impossible for cool air to flow. The fan will instead blow warm air because of the heat that is generated in the motor. This problem is usually solved by turning off the A/C for a few hours; allowing the block of ice to melt so that air can flow efficiently. If- when you turn it back on- it still blows out hot air, it is likely that another problem could be the cause.
Leaking of Refrigerant
Refrigerant leak is one of the most common reasons why a home A/C may blow hot air. There are many things that can make the refrigerant in your A/C leak. Refrigerant may leak because of a lose joint, typically caused from wear over time. Sometimes it’s not easy to notice a leakage, however: if you suspect that the refrigerant may be
leaking after inspecting your air conditioner, you should contact a professional. Refrigerants are dangerous and should only be handled by qualified professionals.
Wrong Thermostats Settings
Have you checked your thermostat settings? Check to ensure that you have set your A/C to “cool” instead of “warm”. Children or other people can change the settings of your A/C without your knowledge. When you notice that your A/C is blowing hot air, check the setting carefully to ensure that everything is correct. When you are sure that the unit’s setting is correct, but your AC is still blowing how air, there may be another problem.
Dirty Air Filter
Have you check the condition of the air filter in your conditioner? When was the last time it was changed or cleaned? Unfortunately, most people don’t ever think about the air filters until there is something wrong with their A/Cs. Air filters can become dirt and blocked. When this happens, they have to be replaced. Although a dirty filter alone cannot be the reason why your air conditioner is blowing warm air, it contributes to the problem.
So if you are wondering, Why is my AC blowing hot air? during the summer months: frozen A/C units, leaking refrigerant, incorrect thermostat settings, and dirty air filters are the most common problems that can cause your A/C to blow Hot Air. If the simple solutions mentioned above don’t fix the problem, you should not hesitate to seek professional help or find out these simple ways to cool your home without A/C.
