Realizing that your air conditioner is not cooling your home in the middle of the summer can be a problem. Several reasons can disrupt the system and cause the air conditioner to stop blowing cold air. 

Typical Causes Of An Air Conditioner Not Cooling Your Home

  • Thermostat issues.

  • Blocked air vents and dirty air filters.

  • There is a refrigerant leak.

Let’s take a closer look at each of these difficulties to assist you in detecting the source of the problem and discovering a solution.

Steps To Assist You In What To Do If Your Air Conditioner Isn't Cooling Your Home

If your air conditioner is not cooling your house or has poor airflow, you’ll need to perform some troubleshooting steps to figure out what’s wrong with your AC system. There are several basic steps that homeowners can do on their own.

Most are tasks that almost any homeowner could accomplish on their own. However, technical issues may necessitate the assistance of professional Ac Repair in Gladstone to identify and resolve. They have service and repair experience and training.

Check Thermostat

If your air conditioning is not cooling your home, the first thing to check should be the thermostat. These devices regulate AC system operation and, if they fail, can make it appear that something is wrong with your cooling system. 

Thermostats are widely accessible and affordable to replace. They should be one of the first to examine if you are experiencing AC problems. Here are a few thermostat troubleshooting steps that every homeowner should follow.

  • Check that your thermostat is set to cool rather than heat or fan. 

  • If you haven’t reset your thermostat since the winter, it may be set to a higher temperature than the outside temperature. Lower the desired temperature to a level less than the current air temperature in your home.

  • If adjusting the temperature doesn’t work, there could be a problem with the connection between your thermostat and the air conditioning system, which requires professional help.

  • Your air conditioner isn’t blowing cool air because the batteries in the thermostat have discharged. Simply replacing the batteries in your thermostat may be required to bring your air conditioner back to working correctly.

  • The thermostat’s position may prevent your AC system from keeping the desired temperature within your home. It might be in a location where an air vent blows directly on it, rapidly cooling it below the target temperature. 

  • That causes the thermostat to transmit a signal to turn off the system, resulting in insufficient cooling. Place your thermostat away from vents and out of direct sunlight. If the thermostat is in an undesirable location, you may need to relocate it.

Check Air Vents And Air Filters

When you find your AC system is not blowing cold air, a blockage is most likely the cause. Make sure nothing is blocking the vents. You may unknowingly restrict your air vents; a piece of furniture may be blocking the airflow, or you may have closed some air vents and forgotten to reopen them. This process reduces HVAC airflow, making you stuffy and uncomfortable during the hot summer. 

Fortunately, this problem is simple to resolve; inspect all of your home’s vents and open any that are closed or remove any obstructions that are in the way. If this does not solve the problem, check your air filter. Clogged air filters may be the source of your AC not cooling your home effectively. Air filters are responsible for keeping the indoor air clean. They remove mold, pollen, dust, pet dander, and other contaminants from the air. They need to be cleaned monthly, depending on how often you use them. 

If they become clogged with debris, they can obstruct airflow, resulting in poor airflow or not cooling your home. If you leave your filters dirty and blocked for too long, your air conditioner may cease operating entirely. Your system should be operational again after replacing the filter. If this does not help, it suggests that something else is wrong with your AC system.

Check Refrigerant Leakage

Refrigerant is necessary for your air conditioner to function correctly. That is a chemical that enters your indoor and outdoor systems. If your AC isn’t cooling your home, a low refrigerant level could be the cause. You cannot effectively remove humidity and heat from the air without the proper refrigerant level. 

If you have a refrigerant leak, it might cause poor system performance and possibly unit shutdown. To determine whether your air conditioner is malfunctioning due to refrigerant leaks, inspect all aspects of your AC unit to pinpoint the source of the leak. To detect a refrigerant leak, examine the area around your unit for frosty buildup. 

A hissing sound could also indicate a problem with the refrigerant. If you discover some fluid escaping from your system during this check, you should contact a licensed expert to make any required modifications and restore the flow of cold air in your home.

Schedule Regular Professional Maintenance Visits

It is recommended that you get your air conditioning system serviced and maintained by a professional to keep it running efficiently. With regular maintenance from skilled professionals, you can improve the operational efficiency of your AC to enjoy the highest level of comfort when it comes to home air conditioning.

Get your air conditioning system serviced at the recommended intervals to ensure peak performance. An unmaintained air conditioner can raise your electricity bill while not effectively cooling your home. As a result, take good care of the system to avoid costly air conditioner maintenance and repairs.
