Why is my AC temperature not going down? — An in-depth guide for homeowners

Here are a few reasons why your AC temperature may not be going down:

Check to see if the thermostat unit is set to “cool”

One of the most common reasons why an air conditioner isn’t cooling is because the thermostat unit is set to “heat” instead of “cool.” If this is the case, simply switch the setting to “cool” and see if that solves the problem.

Assess the condenser

The next step to check is the condenser. The condenser is responsible for releasing heat from the refrigerant, so if it isn’t working properly, your AC won’t be able to effectively cool your home.

To clean the condenser, start by powering down your AC unit. Next, remove any debris that has accumulated around the condenser using a brush or vacuum. Once you’ve removed all of the debris, turn on the power and see if the AC unit starts cooling normally. If it doesn’t, then you may need to call a professional technician for help.

Change the batteries in the thermostat unit, just in case they are dead

One of the most frustrating things that can happen during a heat wave is when your air conditioner suddenly stops working. If you find yourself in this situation, there are a number of things you can try before calling a technician. First, check to see if the batteries in your thermostat unit are dead. If they are, simply replacing them may be all that is needed to get your AC up and running again.

Make sure that the air filter is clean and not clogged with dust or dirt

One of the most common reasons why your AC unit might not be cooling your home properly is because the air filter is dirty. A clogged air filter prevents airflow and makes it harder for your AC unit to do its job properly.

In order to fix this, simply locate the air filter and clean it off with soap and water. You should also check to see if the filter needs to be replaced. Depending on the type of air filter you have, it may need to be replaced every one to three months.

If there is a lot of debris or leaves blocking the outdoor unit, clear it away

Is your AC temperature not going down as it should? There are numerous potential explanations.

Outdoors, there are two things that can prevent air conditioning: debris and leaves. To clear away the former – just grab your vacuum cleaner!

For leaves you’ll need a leaf blower; make sure it’s clean before operating because dust will get everywhere including inside of units where it’s bothersome but not dangerous unless they have particulate filters which must be changed regularly according to manufacturer recommendations.

Turn off all appliances and electronics in the house that generate heat

If you’re still asking yourself, “why is my central AC temperature not going down?”, one of the most common reasons is that there are appliances and electronics in the house generating heat. When these items are in use, they add heat to the air inside the house, making it harder for the AC unit to lower the temperature.

To remedy this, simply turn off all appliances and electronics that generate heat when you are not using them. This will allow the AC unit to more easily lower the temperature in the house. Additionally, you can try opening windows and doors to let some of the hot air out of the house. By taking these simple steps, you can help ensure that your AC unit operates more efficiently and effectively.
