My AC Is Running, But Not Cooling My House: Why?

ICSNY • Oct 17, 2022

If you live in the local area, you understand just how hot and humid it can be. When you turn on your air conditioner, you expect it to behave appropriately; however, it can be frustrating when you realize it is not putting out any cold air. You do not want to overheat, so you need to figure out what is happening as quickly as possible. What are some of the most common reasons why your air conditioner might be on, but not cooling your house?

1. The Thermostat Is Not Set to the Right Temperature

One of the first reasons why there might be an issue with your air conditioner is that the thermostat is not set properly. First, make sure your thermostat is not set to “heat.” Then, if you have confirmed that is not the issue, take a look at the temperature. You need to make sure that the temperature is set appropriately. If the temperature is not set cold enough, then your air conditioner will not know to turn on.

2. The Condenser Is Blocked

There is also a chance that your condenser unit might be blocked. The condenser is typically outside your home. Take a look at the condenser and coils. Make sure they are not covered with grass or dirt. If they are blocked and any way, it can severely hamper the efficiency of your air conditioner. You should also check to make sure they are not too close to outdoor furniture or the fence. You might want to call a professional if you need help cleaning the condenser. You don't want to break it, as it is very expensive to fix.

3. The Filter Is Dirty and Must Be Replaced

If you have a lot of debris clogging your air filter, your air conditioner will not be able to work appropriately. There are some situations where your air conditioner might be working so hard that it has to turn off. From time to time, you need to replace your air filter. You should also invest in routine maintenance that can examine your air filter for you, letting you know if it has to be replaced ahead of time.

4. There Is a Refrigerant Leak

Finally, there is also a chance that there is a refrigerant leak in your air conditioner. Refrigerant is important because it allows you to exchange heat and cold air, keeping your house at the right temperature. There is a chance that your refrigerant level might be low, which means that you need to top it off. At the same time, you must call a professional who can take a look at your air conditioner and make sure there is not a leak somewhere. If there is a refrigerant leak, it can hamper the efficiency of your air conditioner, driving up your utility bills.
