How to Improve Air Conditioner Performance

Maximum Performance

Feel like your air conditioner is struggling? Practical advice to help your split system operate efficiently and save money in running costs.

Before looking at the air conditioner itself consider first how you can use your home to help reduce the heat load.

Check Your Windows and Doors for Leaks

Homes that are "leaky" make the air conditioner work harder to keep it cool. In Australia it's said we live in glorified tents due to the amount of air leakage of our homes.

Gaps around windows and doors allow heat from outside to come inside which the air conditioning has to fight against and can greatly affect the performance of a system. So take steps to ensure all external doors and windows are properly sealed.

Shade Your Windows

Direct sunlight through glass can have a big impact on your air conditioning system. You know what it's like to get in a car after it has been in the sun in 40 degrees all day. So shade your windows using curtains and blinds and use exterior shutters if you have them.

Have a look at Your Home | Passive Design | Passive Design Shading for more information.

Check and Clean Filters

This is one of the first things that we check and the cause of 90% of under-performing air conditioning systems. Filters that are blocked with dust restrict air flow, reducing the amount of cooling. Sometimes they can reduce airflow enough to freeze your air conditioning coil. So check your filter regularly and change or clean when it's dirty.

Set Temperature Efficiently

Operate system in relation to weather. Setting the temperature to 21°C while its 40°C outside is inefficient and will cost you money in high energy bill costs and put strain on the system. Likewise in winter set temperature low rather than 25°C+. Ideal temperature settings are 22-24°C in summer and 19-21°C in winter, but this is just a guide and everyone's comfort levels are different. Also operate system before extreme temperatures. If the forecast is 40°C+ start the unit earlier or setup an automatic schedule.

Do you need maintenance on your air conditioning system?

If after taking all these steps the system still doesn't perform as you expect, it may be time to consider a service or upgrading to a newer more energy efficient unit.
