How to Lower Your AC Bill in a Heat Wave

Heat waves push air conditioners to their limits. These steps can help you stay comfortable while reducing strain on your system and your bill.

Pre-cool and hold steady

Cool the home in the morning while outdoor temperatures are lower, then keep the thermostat at a steady, reasonable setting. Large swings make the system work harder to catch up.

Block the sun

Close blinds and curtains on sun-facing windows, especially west-facing windows in the afternoon.

Keep air moving

Ceiling fans help you feel cooler at a higher thermostat setting. Keep supply and return vents unblocked by furniture.

Check the filter

A clogged filter restricts airflow and reduces efficiency. A quick check before a heat wave is one of the easiest things you can do.

Give the outdoor unit room

Clear plants and debris from around the condenser so it can release heat effectively.

If it still cannot keep up

If the system runs constantly without reaching the set temperature, it may need service or could be undersized. A professional inspection can tell you which.
