So, how often should you check? Think of it this way. There is no such thing as checking too much, but you can easily not check often enough. So, we recommend checking your filter at least once every 4 weeks. It may not always need to be changed during that four week checkup (sometimes it can last 6 weeks or longer), but it’s good to take a peek.
Why is this so important? Because filters that haven’t been checked and changed as needed have a habit of building up excess sediment and debris. Not a problem when it comes to actually working, but a huge problem when it comes to your energy bill. The harder a system has to work to keep you house cool, the more energy it draws and the more you pay to have cool air in your home. And it will break down much faster as a result of overwork and dirty filters.
Changing an AC Filter
If your filter is ready for a swap, here are some quick tips to get the job done:
» Find Your Filters – If you don’t know where your filters are, ask your contractor on the next visit or look near the return grills by the thermostat.
» Remove the Filters – Open the latches and pull the old filter out to check it. You should be able to see clearly through a permanent filter and a disposable one should still be white. If this isn’t the case, it’s time for a cleaning/replacement.
» Clean the Area – Clear the grill and area of any debris and sediment that might make the filter worse after replacement.
Proper filter maintenance only takes five minutes and it will save you money every month you run your AC – not a bad deal for a few minutes’ work.
