central air conditioner for home

When Buying:

Tips for Use:

  • Keep your air filters clean. Filters full of dirt impede air flow through the unit. Replacing a dirty, clogged filter with a clean one can lower your air conditioner’s energy consumption by 5% to 15%.
  • Consider hiring a professional technician to inspect, clean, and tune your system every 2-3 years.
  • Set your thermostat as high as possible in the summer. Aim for 78 ºF.
  • In summer, keep your house warmer than usual when you are away and lower your thermostat when you are home. This is simple with a programmable thermostat.
Home ventilation depiction
  • Ventilation is the most energy efficient and low cost cooling system.
  • Natural ventilation can be supplemented by ceiling fans, window fans, and whole house fans.
  • Prevent heat build up by using window blinds and treatments to block sunlight and radiated heat.
