Central air conditioners are designed to cool every room in a home evenly. However, if your air conditioner is too small for your house, it won't provide adequate cooling, and some rooms will be cooler than others. If you are having problems cooling your home, here are three other signs that your air conditioner may be too small.
1. AC Not Shutting Off
The amount of time that an air conditioner runs before it shuts off is known as a cycle. An air conditioner will continue to run as long as the thermostat reads that the desired temperature hasn't been met. The length of your air conditioner cycles is a good indicator of how well it is sized for your home.
When your air conditioner is too small to cool properly, it will exhibit long cycle times. If it sounds like your air conditioner is constantly running but your home isn't comfortable, it may be time to consider an upgrade. However, you should also consider getting your thermostat tested to ensure the problem doesn't originate there.
2. High Energy Bills
Heating and cooling are the biggest factors in your monthly energy bill. The amount you pay for cooling goes hand-in-hand with how long your air conditioner runs. Naturally, this means that a small air conditioner running in long cycles will lead to an increase in your bill.
If you suspect your air conditioner is too small based on your monthly bill, there are a few other factors you must consider. Changes in your air conditioner usage habits can affect your bill, as can drastic changes in outdoor temperature. If your bill has suddenly spiked or is gradually climbing, it may indicate that a component is wearing or malfunctioning inside the unit rather than that your AC is too small.
3. High Indoor Humidity
Your air conditioner's most important job after cooling your home is controlling indoor humidity. When your blower motor blows warm air across the AC evaporator coils, the air is both cooled and dehumidified. An air conditioner that is too small won't be able to remove as much moisture from the air so your home will stay more humid and uncomfortable than it should.
Air conditioner sizing is one of the most important aspects of home comfort. If you are experiencing these signs of a too-small air conditioner in your home, an upgrade could provide the comfort you need at a lower monthly cost.
