What To Do If My AC Is Not Cooling

With the extreme temperatures that Texas typically sees in the summer, we all know how important it is to have an effective cooling system.

6 AC Function Checks

When your AC stops blowing cold air into your home, there are several reasons why this might be happening. Take a few minutes to check the following functions before throwing in the towel – it might be an easy fix!

Set Your Thermostat

A thermostat is a prime place where a simple mistake can take place. If your thermostat is set to FAN on accident, the AC unit will blow air through the ducts but not cool it. Double-check your thermostat to make sure it is set on AUTO or cooling mode. This will ensure that the process of cooling is actually running and providing cold air to your home.

Air Filter Maintenance

As a homeowner, it is important to check and change out your AC’s air filter every few months. The collected dust and air debris in the filter can stop the air from flowing efficiently through it. This causes strain on your AC system and can lead to warmer air blowing into your home. Set a schedule to remind yourself to change the filter. If you do regularly change the filter, take the time to see if more dust than usual has coated your air filter.

Check Your Ducts

The ductwork running throughout your home can be extensive, and that means there are many places that a malfunction can happen. If you have access to them, check your ducts for any noticeable leaks, holes or damage that could be letting the cold air escape before it reaches the rooms in your home. You can also check to see if anything is inside the ducts blocking the air. Unfortunately, it’s possible for curious critters to become trapped inside the duct and their body may be blocking your air.

Outdoor Debris

The outdoor unit of your AC system sucks in air from the outside as part of the cooling process. It is worth it to take a look at the unit to make sure no debris like tree branches or leaves are blocking the intake of air. Clear any debris away from the unit to make sure it doesn’t cause damage or stop the airflow.

Condensate Drain Blockage

There is a tube that leads out of the AC system that is designed to funnel extra moisture away from the inner AC parts. If a clog or blockage has formed in the tube, it could stop water from draining out. This can cause the system to work incorrectly. Locate the condensate drain line and check for any clog in the end. You can even use suction from a vacuum or shop vac to suck out clogs higher in the tubing.

Clean AC Coils

There are two sets of coils within your AC system, and both can become dirty. When condenser or evaporator coils are dirty, they cannot perform their duties correctly and can cause warmer air to blow. If you want to try to clean the coils, carefully read the instructions on your unit and use the appropriate cleaning techniques and solutions.
