maintenance reaps big rewards!
If you call John Boyd for
your seasonal maintenance, your technician will
change your heating and cooling filters as part

changed as often as every month, depending on
the type of filters you use.
Standard filters are made
of fiberglass and rimmed with light cardboard.
These filters are designed to capture the
particles necessary to keep your equipment clean
and running efficiently, not to clean the air.
Standard filters should be changed monthly while
heating or cooling equipment is in use.

increased air quality, youíll need higher
efficiency filters designed to trap smaller
particles like dust and pet dander. High
efficiency filters should be changed every three
