Is My Air Conditioning Unit Too Small?

Updated: Jul 15


Air Conditioning - Dillon's h&c

In Kansas City, we know the value of coming home to a cool house on a hot summer day. You can give thanks to your air conditioning system for a comfortable and perfectly cooled place to live.


That is if your home IS cool and comfortable. If your air conditioning system is not cooling your home, a number of issues could be to blame. One of them is something many people don't consider!


Did you know that an air conditioning system can be too small for your space? How do you know if your air conditioning system is big enough for your square footage?


We are here to fill you in. Read on to see the signs that your AC unit is too small for your house and why you need to have one adequately fitted.




Air Conditioning Systems


When you purchase an air conditioner, a professional HVAC technician should come to your property, assess the size, and recommend a unit. You might have a system in mind, but you and the HVAC technician can discuss some factors that contribute to the choice, such as:


  • SEER rating

  • budget

  • quality

  • ductwork

  • square footage of the home


It is crucial to consider the above factors, or you may end up with an air conditioning system that is too small for your home.




What Happens if my AC Unit is Too Small?


If you have ever gone into an area of your house and found it cooler or warmer than other parts of an otherwise reasonably cool home, several things may be responsible for this, and one of these is an air conditioner system that is too small for the space.



Signs That Your Air Conditioner is Too Small


Low Airflow


If you have noted that the air coming from your vents seems to be less than forceful when the temperatures soar, it can be a sign that your AC unit is too small for the square footage of your home.


Low airflow can also result from dirty air filters, so it is important to check your filters and either clean or replace them to rule this out. If the problem persists, your air conditioning system could be too small for the size of your house.



Continuously Running or Cycling Air Conditioning


When you program your air conditioning system, your AC should reach the temperature you have chosen, at the specific time you have chosen. Your system works by taking hot and moist air, transforming it through a cooling process to achieve that set temperature.


This means that it should shut off when it reaches that set temperature.


But, if the air conditioning unit is too small for the size of your home, it will try to run the cycle repeatedly. It will be unsuccessful, too. An air conditioning unit that is too small cannot properly cool your home.


Unfortunately, this will also impact your energy consumption and your utility bills. If you are curious to see your current unit's BTU capacity, check the label on the AC itself.


If you bought your home with the current AC system and notice signs that the system is too small, give a reputable HVAC technician a call to check it out.


On the other hand, if you have a new AC system installed, an HVAC professional should discuss with you the importance of your ceiling height, insulation used, sunlight in the home, the number of inhabitants, and the square footage. These factors play a large part in your decision about which AC unit you install.


A good rule of thumb to remember is that a standard air conditioning system cycle is between twenty to thirty minutes. Any longer and it might be a sign that you are facing a problem and need the help of a professional HVAC technician.



Your Home Is Not Sufficiently Cool


If your home is not cool enough, it could be one of many reasons. If you or a professional have ruled out dirty coils or dirty air filters, a refrigerant leak, or a clogged condensate line, your air conditioner may be too small.


A professional HVAC technician can complete a thorough check of the system to eliminate potential issues which will help you discover the true culprit.



The Temperature in Your Home is Inconsistent

If you have rooms or areas of your home that are cooler than others or significantly hotter, this is a sign that your air conditioning unit is too small for your home's square footage.





An insufficiently sized air conditioning system does not have the might to push air to all of the rooms in the house, especially those that are the farthest from the unit itself. Your air conditioner should be powerful enough to cool all of the rooms of your home to the same temperature.


Call an HVAC technician to check the size of your system versus the size of your home, which will ensure that you are not wasting energy and money trying to cool your entire house with a system that will never do so.



Your Utility Bills are High


Most people will try to turn the AC unit on or adjust the thermostat when their house is not cool enough. This will cause some of your rooms to be very cold and yet still not reach the desired temperature in the rest of the home.


When your system continuously runs, you are squandering energy and money. Your energy bills will be higher than expected when the temperature is hotter than average, which signifies that your air conditioning is not functioning at its optimal level.
