The air conditioner coil access door employs industrial strength double sided adhesive tape and extreme care must be used in its orginal placement on the air conditioner coil housing between the air filter and the evaporator coil. A hole is then cut in the housing using the Air Conditioner Coil Access Door as a guide. You now have direct access into the housing — making the once difficult and expensive job of cleaning the evaporator coil a breeze!
