About 87% of Americans depend on their ACs to cool their homes. When they fail to do that, the comfort level in a home is reduced. Particularly during summer, when your AC is not working, your home becomes almost inhabitable. If your AC is no longer cooling your home, here are the common reasons why that might happen.
Clogged Air Filter
Cool air needs to pass through the air filter before cooling your home. When the air filter is okay, your home is cooled, as usual, giving you maximum comfort. Particles get trapped in the filter so that you are breathing fresh air. However, there is only so much that the air filter can take. If you do not clean or replace it, it will eventually clog. And when that happens, less air will pass through. You can replace your filters yourself without calling an expert. If the filter is reusable, soap and water are enough to clean it. HVAC technicians recommend inspecting the filter every 30 days to check whether it needs cleaning or replacing.
Improper installation, pets, and other mishaps can lead to a leaking duct. Since ducts are responsible for distributing the conditioned air to your home, they no longer work effectively when damaged. This also leads to you dealing with high utility bills. Noise is also another sign that your duct has an issue. If you hear a pinging or popping sound, there could be a loose metal or flap in the ductwork. If there is a lot of dust, mold, or pests in your ducts, you will need air duct cleaning Nashville-based to keep them working effectively.
You Have Set The Thermostat Incorrectly
Sometimes the problem is as easy as your thermostat setting. Depending on the thermostat you own, setting it to ‘ON’ does not necessarily guarantee you will get cool air. It could cause air to blow, but the air conditioner is not operating. You can first check whether you have switched on the air conditioner and, if not, switch it on. The next step is setting the temperature to about 5 to 6° lower than your home’s temperature. After that, you will hear the outdoor unit turn and the fans start spinning. Give it a few minutes, and soon you will be enjoying a cool home.
The Size of Your AC is Wrong
Unfortunately, this is an expensive problem to have as you will need another AC unit. If you get the wrong unit size for your home, it will not work correctly. When the size is too small, it overworks in order to give you the desired temperature. The process will take longer than usual and eventually wear out your AC. When the unit is big, the AC will repeatedly turn on and off. Even if the air is cool, it will not be consistent. The only way to fix this is by changing your unit.
Some of these problems can be avoided by simply scheduling regular AC maintenance from a professional. This allows you to have cool air when needed while increasing the lifespan of your unit.
