Air conditioning systems can malfunction in a variety of ways. If yours is showing any of the following signs of not working properly, then it is time for you to call an air conditioning repair service to get it checked out.

1. Bad Smells or Strange Noises

Noises and smells are two early signs of a problem with your air conditioning system. A burning smell indicates that the motor that drives the fan is well on its way to burning out, whereas a damp smell suggests that there is too much moisture building up inside the unit, which could indicate a problem with the condenser.

Malfunctioning air conditioning systems often make banging, rattling, or grinding noises before failing completely. Never ignore strange noises coming from your air conditioner. Instead, call a repair company to address the root of the problem.

2. Poor Air Flow

If there is only a weak flow of air from the vents of your air conditioning system, then there is likely to be either a problem with the fan or a tear in one of the ducts that transport air around your home. Finding and fixing a leak in a duct can be a difficult job, so it is best to enlist the help of an air conditioning repair company to fix this issue.

3. Vents Blowing Warm Air

Sometimes, the amount of air flowing through the air conditioning vents is fine, but the temperature is much too warm. If your air conditioner is blowing warm air, first check the thermostat settings to ensure it is set to cool. If the settings are correct and the unit is still not delivering cold air, get in touch with an HVAC repair service as soon as possible.

4. Energy Bills Seem Too High

The cost of energy is rising all the time, so it is normal for energy bills to rise a little each year. However, if your energy bills have suddenly increased, then the reason could be that your air conditioning system is no longer working at maximum efficiency.

Many problems can cause an air conditioning system to use an excessive amount of energy. Some of these issues, such as clogged filters or a dirty unit, are easy to solve. Others, such as problems with the condenser, require the help of a professional. If you have tried cleaning and replacing the filters in your unit with no success, contact a local HVAC service to find out why your system is using so much energy.
