How to lower the cost of running a central air conditioner
Central AC is usually the single largest electricity user in a home during summer. Power draw depends on capacity (tons) and efficiency (SEER2 rating): a 3-ton system typically draws 3–4 kW while running. The compressor cycles on and off to hold your thermostat setting, so enter the hours per day it actually runs — on a hot afternoon that can be most of the day, while on a mild day it may be only a few hours.
- Each degree you raise the thermostat in summer saves roughly 3% on cooling.
- Replace the air filter every 1–3 months and keep the outdoor condenser clear of debris.
- Use ceiling fans so you can set the thermostat 3–4°F higher with the same comfort.
- Summers in Wyoming are relatively mild, so cooling costs are concentrated in a few hot weeks each year.
