Run A/C smart in summer months

Summer is just around the corner and just like the heat, electricity and fuel costs continue to rise. The following advice by Martin Casillas of Aire Serv of Clark County will help residents stay cool with low- or no-cost solutions.
“Residents can maximize the cooling potential of their air conditioner by doing a few simple things, such as closing drapes on the sunny side of their home and replacing dirty air filters,” Casillas said.
Other tips include:
* Trim shrubs and bushes to allow at least 2 feet around an outside air-conditioning unit, and keep the top of the unit free from all growth.
* A dirty outdoor condenser should be cleaned by a professional technician to allow greater air flow and distribution across the coil. A service technician will oil the motors and check the refrigerant charge and electrical components for safety hazards. A system tune-up also promotes less energy usage and greater indoor air quality.
* Delay heat-generating activities such as dishwashing or baking until the evening on hot days.
* Don’t let in unwanted heat and humidity. Keep the house closed tight during the day.
* Check the filters monthly and replace as necessary.
* Use the ceiling fan only when you’re in the room. Running the fan doesn’t lower the temperature, but it does increase evaporation from your skin to help you cool off.
Residents also can save money by:
* Installing a programmable thermostat. A “smart thermostat” can turn on the air conditioner to the desired set point one hour before you arrive, avoiding the need to run the system all day.
* Set the thermostat as high as comfortably possible in the summer. Each setting below 78 degrees increases energy consumption by approximately 8 percent.
* Upgrade an out-of-date air conditioner. Units prior to 2006 are inefficient and can use twice the electricity of newer models.
