Get regular tune-ups (twice a year) to keep the system
operating
efficiently and to prevent costly
repairs. It's much easier, and
often cheaper, to prevent damage
than it is to repair damage.
Don't forget to change your air
conditioning and heating system
filter once a month. This will help to reduce indoor airborne
particles
that may increase the number
of problems you experience with
allergies, colds and the flu.
