  • Your heating and air conditioning system should be inspected and maintained yearly (before the start of the cooling and heating seasons) by a licensed professional HVAC technician. You can expect the technician to check the following items. These checks may only be conducted by a licensed professional HVAC technician.

  • Outdoor Unit

  • NOTICE !

  • Failure to follow instructions will cause damage to the unit.

  • This unit is equipped with an aluminum coil. Aluminum coils may be damaged by exposure to solutions with a pH below 5 or above 9. The aluminum coil should be cleaned using potable water at a moderate pressure (less than 50psi). If the coil cannot be cleaned using water alone, Lennox recommends use of a coil cleaner with a pH in the range of 5 to 9. The coil must be rinsed thoroughly after cleaning.

  • In coastal areas, the coil should be cleaned with potable water several times per year to avoid corrosive buildup (salt).

  • Indoor Unit (Air Handler or Furnace)
