AC Electricity Usage

Why Air Conditioners Use Too Much Electricity

Live in a tropical region? Besides the hot and humid weather, energy costs are a headache. It’s fair to blame those costs on your air conditioner.

Like many homeowners, you probably wonder why your AC uses so much electricity. It’s simple; when the mercury rises, your air con becomes a workhorse, working throughout the day to cool you down. As the unit works hours on end, it uses lots of power, which results in high energy bills.

Modern air conditioners are more energy efficient than their predecessors. For instance, air conditioning units made after 2000 use 30-50% less power than models from the 90s. However, electricity costs a lot more than it did back in the 90s. As we work our way to solar solutions, power bills will keep dropping.

How Air Conditioners Consume Power

To understand why air cons are power guzzlers, first consider how they work. Air conditioners operate like refrigerators, but they cool a larger area than fridges. Inside an AC, you’ll find condenser and evaporator coils. Your unit’s pump, or compressor, constantly moves a refrigerant between the coils. This refrigerant is vaporised in the evaporator coil to remove heat from the indoor air. In gaseous state, the refrigerant is pumped back to the condenser where it’s condensed to expel heat. The unit’s blower, or vent, moves cool air into the house and warm air into the cooling system.

Such work consumes power, and the more the AC works to cool temperatures, the more electricity it uses. Locating electrician services to get the wiring installation correct can be beneficial for machine productivity. During summer, cooling costs shoot up. For instance, running a split system 4 hours a day will add an extra $200 to your power bill.  Expect to pay $1000+ for the luxury of a ducted reverse cycle air conditioner.

Cut Air Conditioning Bills

Here are 5 ways to keep your home comfy while reducing the amount of electricity your system uses.

  1. Programmable thermostats: When no one is at home, turn your thermostat up or off. For more energy savings, set the temperature according to your daily schedule.
  2. Maintain consistent temperatures: On hot days, 25oC is fine. In winter, try 20oC. Maintaining such temperatures ensures you’re comfortable all day long.
  3. Use blinds and drapes: Close curtains on windows facing the sun.
  4. Maintain your air conditioner: To keep your AC running at peak efficiency, clean its coils. Investing in quality filters and replacing them regularly helps. Hire an expert technician to tune-up your unit.
  5. Supplement your AC with fans: Ceiling fans circulate air, making it cool. Turn fans off if no one is in the room to revel in the breeze.
  6. Buy the right air conditioning unit: Consult an expert HVAC technician before you upgrade your old unit. Pros recommend the right air conditioner for your home size and the local climate.
  7. Cheap electricity deals: Compare energy plans in your area. The cheapest deal will slash a few bucks off your bills.
  8. Reduce heat levels: Appliances like electronics and refrigerators create heat that overworks your AC. Cook outside or use a microwave because ovens and stoves are hot.
