Undersized Air Conditioner

Living in Florida, there’s nothing like walking into your home on a hot summer’s day and feeling a cold blast of air from your air conditioning system. Unfortunately, that’s not the case for lots of homeowners who have an air conditioning system too small for their home.

Buying an air conditioner requires pre-planning and research. After all, there are so many factors to consider when choosing one system over another. SEER ratings, energy efficiency, and square footage of your home are among the most important.

If you don’t pay attention to these details, you could end up with a unit that’s too big or too small for your home. This will result in an uncomfortable indoor climate and higher energy bills.

What Happens If My AC Unit Is Undersized?

While there are many reasons why your AC might not be properly cooling your home, one of the most common culprits is a system that is too small. Read on to learn more about the signs your air conditioning system is too small to get the job done.

5 Signs of an Undersized Air Conditioner

Below is a list of signs and symptoms of AC unit is too small for your home.

1. Your AC Never Stops Running

An air conditioner works by absorbing the warm air and moisture inside your home, and running it through a cooling process until it reaches the temperature you’ve set on your thermostat. If your AC is too small for the size of your home, it’ll keep working to reach that temperature, but to no avail because it lacks the capacity to cool such a large space. As a result, it never completes a cycle and runs continuously.

For each ton of heat that has to be removed from a home, an AC unit needs to have 12,000 BTUs (British Thermal Units). The bigger your home, the more heat it has. The more heat it has, the higher BTUs required from the AC unit.

When purchasing an air conditioner, it’s important to consider the following circumstances:

  • Square footage of your home
  • Ceiling height
  • Construction materials
  • Insulation
  • How much direct sunlight comes in through doors and windows
  • How many people live in your home

The BTU capacity of an air conditioner is included on a label on the condenser unit (the big box that is outside your home). At the top of the label, you’ll see the model number (M/N) and the BTU capacity, which is the three digit number after the first dash.

A regular cycle should last between 20 and 30 minutes. If this is not the case with your AC system, call an HVAC technician to find out if your air conditioner is big enough for your home’s square footage.

2. Low Airflow

This could also be a sign of dirty air filters. But if you’ve cleaned or changed your air filters and still don’t notice a difference in the amount of air that comes out of your vents, you may have an AC that’s too small for your home. However, pay attention to the other signs on this list, since low airflow alone is not a surefire sign of an undersized air conditioner.

3. Your Home Is Never Cool Enough

There are many reasons why an air conditioner may not cool your home properly such as dirty air filters, dirty coils, a clogged condensate drain line, or a refrigerant leak. If none of them apply, yet your home is still not cool enough, the issue may be an AC unit that’s too small.

4. Your Home Has Temperature Inconsistencies Throughout

Do you have that one room in your home that always seems to be too cold or too hot? This is an indication that your AC could be too small. When your AC system is too small, it won’t be powerful enough to reach rooms in your home that are the farthest away from the AC.

An air conditioner that’s the right size will keep consistent temperatures in all rooms of your home. The only exception is kitchens, laundry rooms, and bathrooms, if someone’s cooking, doing laundry or taking a hot shower.

5. High Energy Bills

Since an inadequate air conditioner won’t complete a full cycle, the extra expended energy will result in higher energy bills. There will also be a noticeable spike during the summer, as your unit goes into overdrive trying to match the temperature set on the thermostat.
