Electric company studies show conservation of electricity and savings in cost of operating air conditioners of 28-30% by just cleaning and deoxidizing the condenser coil — and that can be quick and easy with MIRACOIL because the condenser coil is on the outside of the unit and MIRACOIL is formulated especially for this purpose. There's nothing to adjust or even touch inside the unit. Just spray on MIRACOIL and watch. The formula reacts with any build-up of corrosion to create a foam that penetrates the fins of the coil and literally floats soil to the surface. Then, rinse with plain water and return the unit to service.
