Changing the air filter every 30 days is the single most important thing you should
do to keep your air conditioning and heating system working efficiently.

Using the right filter is just as important. Here in the greater Houston area we need
to choose an air filter that won't slow down or choke off the air flow like pleated
style filters. These pleated filters are a front loading design so they just get more
restrictive the day you install one. That means longer run cycles and higher
electric bills. Use a mesh style air filter, not a fiberglass air filter. They are too loose,
and fiberglass dosen't hold a static charge. WE RECOMMEND A POLYESTER
DISPOSABLE or a BI-POLYESTER DISPOSABLE if dust is an issue.

Some homes today have been fitted with extended use air filters. These air filters
are most often located in the attic in front of the blower. They are about 5 " thick to
allow for extended service. You should change extended use air filters 3 to 4 times
per year.
