An important detail in any home is an air filter. Whether you have a new or old central unit, this little piece makes a huge impact and helps your system deliver the cold air that you desire. If you’re not sure when you should replace your filter or why you should change it at all, here are a few pointers to consider:
Higher Energy Bills
Have you noticed something strange with the grand total on your energy bills recently? If so, that can be a sign that you used your cooling system a tad more than usual — but that’s not necessarily always the case. In fact, it’s possible that your system worked harder than it had to when it was on, thanks to a dirty air filter.
When a filter is dirty, it will block the airflow to your system, creating a muffled passageway. This will then make your unit “gasp” for air and work overtime to give you the cool air you’re looking for.
No Cold Air
When you walked past an air vent in your home, did you happen to notice cold air coming from it? If not, that’s a common sign that you’ll need to replace that air filter right away. As mentioned earlier, since a dirty air filter blocks the airflow in your unit and makes it work twice as hard to get the results you’re looking for, it may take a very long time for your home to actually cool down.
Frequently Needing Repairs
Another sign that you should change your air filter soon is that your unit constantly needs repairs. Typically, a central air conditioner will need a few repairs here and there — but if it happens to be a routine every month, then you’ll want to weigh out the odds. Since a dirty filter will make a unit work much harder than it has to, it will eventually cause it to break under pressure — which is enough to be an eye-opener for anyone.
