Even if you probably had never thought about it before, your air conditioner is probably one of your most favorite features of your home. This is why, when you start noticing that it’s not cooling your home, or that you have uneven temperatures despite the fact that it’s constantly running, you worry. A lot.
To add insult to injury, you may have also noticed that your utility bills are also going up. What’s going on, and what can you do about it?
Why Does my AC Keep Running?
An air conditioner works by absorbing the warm air from inside your home, separating the moisture from humidity in it, and cooling it, before sending it back out through the air vents. It will keep doing that until the temperature reaches the number you set on the thermostat. Once it does, the AC shuts off. This is called an AC cycle, and it typically lasts between 20 and 30 minutes. When the indoor temperature starts rising, the AC will start another cycle.
However, if you install an air conditioner that’s too small for your home, it will work on overdrive in attempts to reach the desired temperature, to no avail. And because it never shuts off, the energy consumption will be reflected in your energy bills.
Buying an AC in the Right Size
In order to eliminate all the heat in your home, an air conditioner needs to have a specific BTU capacity (British Thermal Units), which will vary, depending on the size of your home.
For each ton of heat that has to be removed from your house, an air conditioner needs to have 12,000 BTUs. The larger your home, the air conditioner will have to remove a larger amount of heat. Therefore, the bigger the home, the higher the BTU number you’ll need.
But size isn’t the only thing that matters. In addition to square footage, you have to keep in mind the following factors:
– Construction materials
– Type of insulation in your home
– Ceiling height
– How much sunlight comes in
– How many people live in your home
To verify whether this is the reason why your air conditioner never cycles off, check it’s BTU capacity. Go to the condenser unit (If you live in a single family home, it’s the big box sitting outside your house. If you live in a condo, it’s in the furnace closet). At the top of the unit, you’ll see the model number (M/N), which includes a mix of letters and numbers separated by dashes. The BTU capacity is the three-digit number after the first dash.
