Like any appliance that uses electricity, air conditioning has an environmental impact. The good news is that choosing an efficient system, using it correctly and keeping it well maintained can significantly reduce energy consumption and unnecessary emissions.
For homeowners looking to stay comfortable while making more environmentally conscious choices, understanding how air conditioning affects the environment is a great place to start.
Why does air conditioning have an environmental impact?
The biggest environmental consideration associated with air conditioning is energy consumption. Cooling or heating a home requires electricity, and the more energy an air conditioner uses, the greater its carbon footprint can be.
Older or inefficient systems may require considerably more electricity to achieve the same level of comfort as a newer, high-efficiency unit. Poor installation, dirty filters and inadequate maintenance can also cause an air conditioner to work harder than necessary.
Air conditioning systems also use refrigerants to transfer heat. Modern refrigerants have been developed with lower environmental impacts than many older refrigerants, but responsible handling is still important. Refrigerants should only be installed, serviced or recovered by appropriately licensed professionals.
Choose an energy efficient air conditioner
One of the most effective ways to reduce the environmental impact of air conditioning is to choose an energy efficient system.
When replacing an old unit or installing air conditioning for the first time, look at the system's energy efficiency ratings as well as its capacity. A system that is appropriately sized for the room can provide effective heating and cooling without using more energy than necessary.
It's also worth considering how and where the system will be used. Installing multiple units or a ducted system can provide excellent whole-home comfort, but the most suitable option will depend on the home's layout, occupancy and individual requirements.
A professional air conditioning installer can assess your property and recommend a system designed to operate efficiently for your needs.
Use your air conditioner efficiently
How you operate your air conditioner can make a significant difference to its energy use and achieving a greener home.
Rather than setting your air conditioner to an extremely low temperature during summer, aim for a comfortable setting that doesn't require the system to run excessively. The same principle applies to heating in winter.
Using timers and scheduling functions can also prevent your air conditioner from running unnecessarily when nobody is home. If you're only using one room, there's little benefit in cooling or heating the entire house.
Ceiling fans can also help circulate conditioned air, potentially allowing you to use your air conditioner more efficiently. Closing blinds or curtains during hot summer afternoons can further reduce the amount of heat entering your home.
Keep your air conditioner well maintained
Regular maintenance helps your air conditioner operate efficiently and can extend the life of your system.
Dirty filters can restrict airflow and force the system to work harder. Outdoor units can also accumulate leaves, dirt and other debris, which can interfere with airflow and heat transfer. A qualified technician can inspect the system, clean components, replace filters and identify potential issues before they develop into larger problems.
A well maintained air conditioner will deliver consistent performance without unnecessary energy consumption.
Don't ignore an inefficient system
If your air conditioner is taking longer than usual to cool or heat your home, struggling to maintain the desired temperature or frequently turning on and off, it may not be operating efficiently.
These symptoms can have a number of causes, including blocked filters, inadequate airflow, component problems or refrigerant issues. Continuing to operate a system that isn't working properly can result in higher energy consumption, as well as reduced comfort.
In some cases, repairing the existing system may be the most practical option. However, if the unit is older and inefficient, replacing it with a modern system may provide better long term performance and lower energy consumption.
Consider the whole home
Improving your home's thermal performance can reduce the amount of heating and cooling required. Good insulation, effective window coverings, appropriate ventilation and sealing unwanted gaps can all help maintain stable indoor temperatures. Measures such as keeping doors and windows closed while the air conditioner is running can also prevent conditioned air from escaping.
The less heat entering your home in summer and the less warmth escaping in winter, the less work your air conditioner needs to do.
A more sustainable approach to home comfort
By selecting an appropriately sized, energy efficient system, using it thoughtfully and keeping it properly maintained, homeowners can reduce unnecessary energy consumption while still enjoying comfort throughout the year.
