Summer AC bills climb here no matter what, but there's a real difference between a system running efficiently through extreme heat and one working much harder than it needs to. A few practical, honest steps make a meaningful difference without sacrificing comfort.
Get a seasonal tune-up before peak summer
A system with a clean filter, properly charged refrigerant, and clean coils runs more efficiently than one that's been neglected, which shows up directly on your electric bill during the months you're running AC the most.
Use a programmable or smart thermostat setback strategically
A modest, consistent setback while you're away or asleep, rather than turning the system off completely, tends to save energy without forcing the system into a long, inefficient catch-up cycle when you return.
Reduce heat gain before it becomes the AC's problem
Closing blinds or curtains on the sunniest side of the house during peak afternoon heat, using ceiling fans to improve air circulation (which can let you comfortably raise the thermostat setting slightly), and avoiding heat-generating appliances during the hottest part of the day all reduce the actual cooling load your system has to manage.
Address duct leaks and poor insulation
Cool air escaping through leaky ductwork before it reaches your rooms means your system runs longer to compensate, similar to the effect duct leaks have on winter heating bills. Sealing significant leaks is one of the more meaningful efficiency improvements available.
Don't ignore a system that's clearly struggling
A system running constantly without keeping up, beyond what's reasonable during extreme heat, is often working harder (and costing more) than it should due to a fixable issue, low refrigerant, a dirty coil, restricted airflow, rather than just the weather. Addressing that directly usually pays for itself in reduced energy costs.
