Why Your Home's Air Conditioning System Isn't Cooling Properly

Like several other Australian homeowners, you rely on an air conditioning system for relief from the summer heat. If your home's cooling system is turned on and set correctly but still can't keep up with a normal summer day, you'll want to address the issue and get it running properly again. 

AC systems have multiple parts that work together to cool your home. If there's a problem with any part, you may experience a noticeable decline in the cooling performance of your system.

Keep reading to find out some of the most common issues air conditioning repairs services find when fixing air conditioners that aren't cooling properly.

Thermostat issues

Your home's AC system has a thermostat connected to it. The thermostat's job is to regulate the temperature of the air blowing from the cooling system. As such, to start the troubleshooting process for an air conditioner that's not cooling properly, check that the thermostat is on and set to "COOL". Next, make sure the temperature is set at the correct setting for summer weather.

If your thermostat is on and set correctly but your cooling system continues to blow warm air, you may have a broken thermostat. A broken thermostat can't signal to your cooling system that your home interior is hotter than the desired room temperature.

Dirty air filter

Typically located at the air handler and in the return duct, the air filter does the important job of preventing airborne contaminants from entering your air conditioning system. Over time, it becomes clogged with built-up dirt and will need to be replaced.

Air conditioners require sufficient air intake to cycle properly. If you don't replace a dirty air filter in a timely fashion, it will inhibit proper airflow into your cooling system, resulting in inadequate cooling performance. 

Blocked outdoor unit

If your air conditioner has an outside unit, make sure it is kept clear of any obstructions that can prevent efficient dissipation of heat from your home to the outdoor environment. Otherwise, the unwanted heat may increase within the unit and end up being transferred into your home, resulting in warm air blowing from your air supply vents.

Repairing a malfunctioning AC system is a job that requires an expert. Contact the professionals at an HVAC company near you to get your home's AC system cooling properly again. Acting promptly will help to prevent a complete system failure while keeping AC repair bills down. Contact an air conditioning repair service for more information.
