Keeping the condenser clean and clear of shrubbery, leaves, etc., keeping your outside AC unit cool, so it doesn’t have to work as hard by planting shrubs between it and the sun,(maintain several feet clearance around the unit), changing the filters every two months, not covering the cool air vents with furniture and allowing the air to flow normally throughout your home, getting regular annual maintenance checks and cleaning from a professional, using ceiling fans for improved circulation, using blinds and drapes to block intense sunlight, using a programmable thermostat to turn down the AC when you are away or at night when it is cooler.
