:115 Clean AC Coils

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet.

1:5:10:115 EcoTip: It is time have your air conditioners cooling coils and system cleaned to prepare for a hot summer. Have it done now and your system will be ready when the hot weather hits. Dirty coils waste energy by creating greater resistance to air flow and can also be a source of poor air quality from microbial growth. Studies have shown that if you have a unit with both inside and outside coils (as shown below)- they need to be kept clean too.

 Primary reasons for cooling coils become fouled are that inefficient filters are used, or are not preventing dirty by-pass air from going around the filter instead of through it.
