Your AC Is Using Too Much Electricity?

September 12, 2025

Worried your AC is using too much electricity? Here are easy tips to cut your AC’s energy use from your trusted air conditioning Gold Coast service – DEEPCHILL. 

Why my AC is using too much electricity than it should?

Old air conditioner

Older machines often work less efficiently. As parts wear out (like the motor or compressor), the AC needs more power just to keep the room cool. Newer models have better technology to save energy but old ones don’t. That’s why your bill keeps climbing even if you use it the same way.

Poor maintenance and air leaks

When your AC isn’t cleaned or checked regularly, dust and dirt build up inside. Dirty filters or coils force it to work harder and use more electricity. On top of that, if your room has gaps around doors or windows, cool air escapes and hot air gets in. This makes the AC run longer to keep things comfortable, which also wastes power. 

Wrong size AC for the room

An AC that’s too small will run nonstop and still won’t cool the room properly. One that’s too big switches on and off too often, wasting electricity too. Choosing the right size for your space is key to help when your AC is using too much electricity.

Blocked or dirty ducts and vents

When air can’t flow freely because of dirt or blockages, the AC works harder and longer. Keeping ducts and vents clean helps the system run smoothly and saves energy.

4 practical ways to increase the energy efficiency of your AC system

Clean or replace the air filter regularly

When the air filter is dirty, airflow gets blocked. This makes the AC work harder and use more electricity. Cleaning or changing the filter every 1–3 months helps air move freely and keeps the unit running smoothly. It also protects the AC’s parts and helps reduce when the AC is using too much electricity.

Keep the outdoor unit and vents clean

The outdoor unit needs space to breathe. If dirt, leaves or debris pile up around it, airflow gets blocked and power use goes up. Inside the house, make sure vents are open and not covered by furniture or dust. Keeping both the outdoor unit and vents clean helps the AC cool better while using less energy.

Seal air leaks in your home

Gaps around windows and doors let cool air escape and hot air sneak in. This makes the AC run longer and waste more power. Sealing these gaps with weather strips or caulk keeps the cool air inside so the AC doesn’t have to work as much. That means lower bills for you.

Set the thermostat a bit higher

The lower you set the temperature, the harder your AC works. Keeping it around 25–27°C instead of too low saves energy. You can also use fans to feel cooler without pushing the AC too hard. Even raising the setting by just one degree can make a big difference.

Schedule regular maintenance

Having your AC checked once a year by a professional keeps it in good shape. They can clean the hidden parts and fix small issues before they turn into big ones. Regular maintenance helps prevent breakdowns and keeps the system running efficiently with less energy use.

If you’ve noticed your AC is using too much electricity, you should consider look at how well the system is running. Small issues can make the AC pull a lot more power. For expert help, you can always contact DEEPCHILL, your trusted air conditioning Gold Coast service.
