Air conditioning is essential for keeping your home cool and comfortable through the hot Ohio summer. While most of today’s cooling systems are extremely reliable, regular tuneups will keep them running efficiently and prevent expensive repairs. Here are a few signs your air conditioning system needs to be repaired.

What Are the Signs Your AC Needs a Tuneup?

1. Reduced Airflow

Restricted airflow is one of the most common signs that your air conditioning system needs to be checked out. Reduced airflow can be caused by a dirty air filter, blocked ducts, or a faulty fan motor. Not only can this make your home feel stuffy and uncomfortable, it can also drive your energy bills up.

To fix reduced airflow, your technician will first change the air filter. They may check your ducts for any obstructions and inspect the motor for potential issues.

2. Strange Noises


Strange noises, like banging, rattling, or squeaking sounds, are another indicator that your cooling system needs attention. In many cases, these sounds could indicate loose or worn-out parts.

If your AC system is making strange noises, your technician will start by  inspecting the outside of the unit for obvious signs of damage. An HVAC professional can check for and replace any worn-out parts.

3. Warm Air

Warm air coming from the vents is one of the most obvious signs. A variety of issues could cause your AC to blow warm air, including refrigerant leaks, a malfunctioning compressor, or a clogged condenser.

Warm air blowing from your vents can also be caused by a malfunctioning thermostat. Having a heating and cooling professional check your system can restore the comfort of your home and prevent more serious breakdowns.
