Signs That Tell You Your Unit is Undersized

There are many reasons why an air conditioner is not cooling a house properly, but one of the most common reasons may be that your unit is too small.

Here are some signs that tell you that your air conditioner is too small to cool your room:

  • Inconsistent Room Temperature 

Have you noticed the inconsistent temperature throughout your room? This may be because your air conditioner is too small. If an air conditioning system isn’t big enough, it might not be powerful enough to spread the air in your room. A properly sized air conditioner will cool all of your rooms evenly. 

  • Humid Indoors 

The air conditioners are developed to cool the house and remove excess moisture from the air by absorbing it. If your unit is too small for the room, it won’t absorb all of it. Also, if the thermostat is at the right temperature, but the house constantly feels damp, it could be because the air conditioner is too small. 

  • Your Home is Never Cool Enough 

There can be various reasons why an air conditioner may not cool your home properly, such as dirty air filters, coils or refrigerant leaks. But if these things are fine and still your room is not cold enough, the problem could be that the air conditioner is too small.

  • Your AC Never Stops Running 

The air conditioner absorbs the warm air and moisture in the house and runs the cooling process until it reaches the temperature set by the thermostat. If your air conditioner is too small for the size of your home, it will continue to work to reach that temperature, but it will not help as it cannot cool such a large room. As a result, it runs continuously. 

  • Low Airflow From Vents 

 If you find very little air coming out of the vents while your unit is running, this might also be because your air conditioner is not big enough to provide sufficient air. A properly sized air conditioner will cool the entire house evenly.
