Home habits that support your AC during hot weather
Start with shading, sensible equipment settings, and clear airflow. These steps can reduce avoidable cooling demand, but they cannot fix a fault or guarantee a particular bill.
Limit avoidable indoor heat
Close blinds or curtains where direct sun enters. Consider when you use an oven or clothes dryer. Keep doors and windows closed while air conditioning runs. Any outdoor cooking must follow fire and carbon-monoxide safety instructions; never bring a grill indoors.
Keep airflow clear
Move furniture away from room registers and return grilles. Follow the equipment maker’s outdoor clearance instructions. Do not enclose the condenser, cover it while it runs, climb onto a roof, or reach through a fan guard.
Follow your equipment instructions for filter checks and replacement. Do not seal attic vents or combustion-air openings as an energy-saving project.
Use controls that fit your equipment
Review the thermostat schedule, rather than repeatedly changing settings. In cooling mode, a higher set temperature requests less cooling. Follow the manual and keep the home safe for the people and animals inside. Heat-pump heating settings may need a different approach.
See ENERGY STAR’s heating and cooling guide for general cooling measures.
Get help for a performance change
If cooling becomes weak, the system repeatedly stops, or you notice a new noise or leak, tell Nalk what changed.
A repair diagnosis has a visit charge. Read what a repair visit costs for the first-hour charge, additional time, parts, after-hours rates, and travel charges. The technician explains repair options and costs before you approve repair work.
