Installing the correct indoor or evaporator coil is essential for getting the highest performance and comfort from your central air conditioning or heat pump system. The evaporator coil is a piece of equipment that is useful in sending cold air throughout the ductwork located in your home. As air is passed through the system, the coil will absorb the heat and you in return get that cold breeze throughout the house. For best performance, it is recommended that you install a brand-name coil with a brand-name air conditioner or heat pump system. And as always, brand-name equipment offers some of the best warranty protection coverage in the heating and cooling industry.
