Troubleshooting common air conditioning problems

As with most electrical appliances, air conditioning systems need a little TLC to ensure optimal efficiency and performance. AC units that have received little to no maintenance will struggle when they’re needed the most.

To ensure your systems remain in top-notch condition all year round, we’ve created a list of the most common air conditioning problems and ways to fix them.

Light airflow

A dirty or clogged filter restricts airflow, which decreases efficiency and impacts the system’s ability to effectively cool the air. To determine whether your filter needs cleaning, remove it from the system and check if any light passes through it. If not, it’s time to get cleaning.

Instructions on how to clean your air conditioner’s filters can be found in the manufacturer’s handbook. It will also advise on how often you should be cleaning them – some are monthly, others are every three months.

Inaccurate temperatures

It’s common for the thermostat to be the main cause of inaccurate room temperatures. If the temperature seems off, make sure the thermostat isn’t exposed to direct sunlight, as it could be registering the wrong temperature. Likewise, ensure it’s turned on, is clean, level and is on the correct setting.

Fluctuating temperatures

An AC system that fluctuates in temperature could be the product of a leaking air conditioner. If coolant is leaking from your air conditioner, the unit will underperform and the temperature will differ when operating. Plus, leaking coolant is incredibly harmful to the environment. To ensure the leak is fixed and the correct amount of refrigerant is re-added to the system, appoint your local air conditioning technician.

Non-stop fan

Uneven refrigerant levels and faulty controls could be the reason why your air conditioning system isn’t turning off. Even during the summer months, your air conditioner should turn off occasionally. If it doesn’t, it could indicate there’s a problem with the fan. Contact your local air conditioning specialist who will be able to advise.

Odd noises

The varying noises coming from your air conditioning unit may determine where the problem is originating from. Screeching or squealing sounds that are coming from the blower motor indicates a motor bearing problem or a faulty belt. Whereas, clanging, rattling, thumping and banging noises generally means there’s a problem with the motor or blowing assembly. Speak to your air conditioning engineer if you’re experiencing any unusual noises from the unit.
