Your HVAC system's air filter is designed to prevent dust and other contaminants from clogging up your climate control system, and also works to keep your air quality and ductwork clear. A clogged air filter can cause all sorts of complications for your home, but thankfully can be replaced by hand. However, identifying when you need to replace your current filter can be tricky. Thankfully, there are several things that you can watch out for to determine when you need to head to a hardware store to pick up a replacement HVAC filter.
1. Constant Operation and Reduced Performance
One of the first signs that your central heating and cooling system is not able to properly draw in air is if you find that it is constantly operating, without a change in the actual temperature of your home. A clogged air filter can reduce the amount of air that your heating and cooling system is actually able to move around your home, which means that it will constantly run as it futilely attempts to reach the temperature set on the thermostat. This can cause increased stress to the mechanical parts of your HVAC system, so replacing the filter as soon as possible is the best course of action.
2. Reduced Air Quality
Another fairly obvious sign that your air filter needs to be replaced is if you find that the air quality in your home has drastically decreased. This will usually be obvious through more dust and other airborne particles floating through the air, requiring more cleaning and maintenance to keep your house looking neat. However, if you have allergies, asthma, or another respiratory condition, you may also notice that you suffer from symptoms more often and more severely than you normally do when your air filter is clogged – especially if it is out of season for high pollen and dust content in the air.
3. Increased Utility Bills
Finally, the last sign of an air filter that should be replaced straight away is an increase in your monthly utility bills without any change in the settings of your thermostat. As mentioned above, an HVAC system that is unable to properly draw air through itself will operate more often to produce the same amount of heating or cooling, using more energy but producing less climate control. Replacing the air filter can restore your comfort levels and bring your utility bills back to what you are used to again.
