Common Causes of AC Inefficiency

There is a seemingly endless list of reasons why you may have inefficient air conditioning in Indianapolis, IN. However, the most common issues come from a few causes. Many have a simple resolution that will allow your air to begin flowing efficiently again. 

Common Causes of Inefficient Air Conditioning in Indianapolis, IN 

A trained HVAC technician can get to the root of your AC problems, but some of the most common causes are detailed below. 

Blocked or Dirty Filter 

An air filter prevents dirt and debris from flowing through your ducts and into your home. However, they can become blocked and unable to do their job. You can inspect your air filter and remove any visible debris. You should replace your air filter at least every 90 days for maximum efficiency. 

Dirty Condenser Coil 

Like air filters, condenser coils become inefficient when blocked or dirty. You can inspect your condenser unit for dirt, dust, or other buildup that could affect the coil's performance. 

Check the area around your unit to remove weeds or grass so they don’t interfere with the condenser. This simple step will help prevent inefficient air conditioning in Indianapolis, IN. 

Insufficient Refrigerant   

An air conditioner requires refrigerant to absorb heat inside the house and transfer it outdoors. If your refrigerant leaks, it might not be capable of absorbing enough heat to create a comfortable home. 

Your refrigerant may leak because of standard wear and tear on the metal tubes. Over time, exposure to moisture and acid causes pinholes to develop in the metal, causing tiny leaks. Slowly, the refrigerant will leave your system, creating inefficient air conditioning in Indianapolis, IN. 

Malfunctioning Thermostat 

The thermostat is the control center of your air conditioner. Any issue with this device easily leads to an inefficient air conditioner. One of the most common problems is an incorrect setting. 

If your thermostat is on cooling and you notice no changes to your temperature, you’ll need an HVAC professional to inspect your thermostat.
