How energy efficient is your air conditioning system? The air conditioner air filter in your heating and air conditioning system protect it so that it doesn't work harder than it needs to resulting in wasted energy and money. Air filters prevent dust from accumulating which would otherwise block the airflow through your system resulting in your system being overtaxed. While there’s no set time-frame to clean or replace your air filter, the best answer is to do it as often as is needed. And really, the only way to know how often this should be done is to check your filters periodically until you know the amount of time it takes for your filter to get dirty. Typically, twice a year is a good idea.

So, how important is it to clean or replace your air filter? Very. The harder your system works the shorter its lifespan and the more energy it will use. Keep your system healthy and running as energy efficiently as possible—check those filters.

Is your air conditioning system noisy? Have your electric bills been going up? If so, that’s not a good sign for your pocketbook or for the life of your system. But it’s certainly a sign that you need regular maintenance visits by an AC Pro.

Your system may be breaking down, have leaks, or it may be clogged with dirt and other elements. Your air conditioning system may well be the 3^rd largest investment you’ll ever make so make sure you care for it the same way you would your car or home.
