Air Conditioners are like cars - they run better when they're kept clean. Keep grass and shrubbery at least 18" from your air conditioner, and have your unit professionally cleaned at least every other year (more often if you're in a dusty environment).

Everybody knows to change their filters once a month but beware of the "high efficiency" filters you see in the big box home improvement stores. Your system needs a lot of air to function properly, and many of the less expensive filters don't allow enough air to flow through them. Ask your Wrenn Tech about the right type of filter to use.

Yes, sometimes ductwork needs to be cleaned, but you are NOT going to get a professional job done for $249. A quality duct cleaning will cost you 3 - 5 times that much, depending on what's needed, and can't be done with a canister vacuum and a handful of rags.
