You may have heard us recommend replacing your HVAC air filter every 1-3 months. This isn’t just something we’re throwing out as a random suggestion—we are offering this advice as a way for you to get the most effective and efficient use out of your heating system as possible. And considering how much we’ve all used our heaters so far this winter, chances are you’d like to avoid problems and spending unnecessary money.
One way to achieve this is by performing that very small maintenance task—changing your air filter when needed. You’d probably be surprised to find out just how important this small HVAC component actually is. It doesn’t just protect indoor air quality—in fact, that’s not its purpose at all. Read on to learn more!
The Purpose of the HVAC Air Filter
As we alluded to above, the main purpose of your furnace’s air filter is not to protect your home’s indoor air quality. Rather, it is in place to protect the furnace system itself. Today’s air filters are designed to optimize air quality as much as possible, but since your furnace’s blower fan sucks in air at such a high speed, it can also suck in dust, dirt, and other debris.
These particles form the air of your home can potentially damage the furnace system, pummeling it with that debris. The filter is in place to protect your furnace form these particles, and a dirty or clogged furnace filter will start creating problems.
Why You Don’t Want a Dirty Furnace Filter
Both your forced-air furnace and your AC system are designed to take in a certain amount of air with each cycle they go through. This airflow ensures you always feel comfortable, but also that the HVAC system motor doesn’t run for too long. Dirt and debris clog up the filter and won’t allow the right amount of air through, which impacts more than just your comfort.
Sure, you will feel less comfort due to the lack of airflow, but you’ll also find yourself paying more to even use your HVAC system. The system has to run nonstop in order to compensate, which results in higher monthly bills. A dirty air filter can also lead to serious repair troubles, such as:
- Freezing Coils
- Emergency Furnace Breakdown
Watch out for these signs and make sure you contact us when you notice a problem.
Changing Your Furnace Filter
Why should you pay to resolve any of these above-mentioned problems when you could prevent them altogether with one simple task? Air filters are relatively affordable, and you can usually stock up on enough for a year at your local hardware store.
