Clean your coils. Keeping your condenser and evaporator coils clean is one of the most important things you can do to ensure your heat pump or air conditioner runs at top efficiency. Over months and years, the outdoor condenser unit coils collect dirt, which reduces air flow and their ability to absorb heat, leading to a steady decline in performance and a steady increase in energy use. You can avoid this by checking your coils every year and cleaning them as necessary. Take the Clean Your Coils Challenge today by clicking on the link below. You will see how much energy and money this will save and how many carbon dioxide emissions will be eliminated. All savings are estimated based on an average 1,500-square-foot home in the LES service area.
