Unless you have an electric water heater or furnace, the air conditioner is the most electrically demanding indoor appliance in your house. When an AC switches to cooling mode, it can consume around 3.0 kilowatts per hour per hour. By comparison, just running a ceiling fan consumes 0.025–0.075 kilowatts per hour. When you have to run your AC regularly, you can expect to see an increase in your regular electric bills, especially if your AC runs too long too often.
But if you’ve had the same AC for several years, you’ll have an understanding of how much that increase will be during the summer. When that increase starts to seem abnormally high and you know you aren’t doing anything different with cooling your home, it’s something to pay attention to. You may need to schedule AC repair in Warner Robins, GA with our team. You might even need to consider replacing the air conditioner. In some cases, an oversized AC system can contribute to higher bills by cycling on and off too quickly, leading to wasted energy.
We’ll look into why an AC might become a massive power-draining below. This will help you know what you need to do to get those costs under control. Part of the solution may involve getting your AC prepped for warmer weather so it runs efficiently before summer’s peak.
Why might your AC bills be so high, and when should you call HVAC service?
- Clogged air filters: Restricted airflow forces your system to work harder and raises energy usage.
- Faulty thermostat: A malfunctioning thermostat may overwork your AC by running it too much or misreading temps.
- Refrigerant leaks: Low refrigerant makes your unit cool inefficiently and consume more power.
- Leaky air ducts: Escaping conditioned air means your AC runs longer to maintain comfort.
- Short-cycling: Frequent on-off cycling strains the system and uses excess energy.
- Aging AC unit: Systems over 10-15 years old lose efficiency, time for a check-up or service.
