Despite the important function they perform, HVAC systems are often ignored until they stop functioning the way they should. What’s even more frustrating is that failing to perform the simple task of changing the air filter is what leads to most HVAC system complications and failures.
Yes, you read that right. That simple, cardboard-framed piece of spun fiberglass is, in fact, a vital component of your HVAC system. It performs the crucial job of preventing contaminants, such as dust, dirt, mold, pollen and bacteria, from entering your home and the sensitive parts of the system.
Here are some of the potential consequences of failing to change your HVAC system’s air filter on time.
Sky-High Energy Bills
When the air filter is clogged, the system has to work extra hard to maintain a steady flow of air and distribute warm or cool air where it is needed. This leads to the system consuming more energy than normal, which naturally leads to higher energy bills.
Poor Indoor Air Quality and Health Concerns
A clogged air filter won’t be as effective at trapping dust, debris, and contaminants as it was before, and all those things will first end up inside your home, and eventually, your family’s lungs. There is a variety of health hazards associated with clogged air filter, including pollen allergies, sinus conditions, and respiratory illnesses.
Furnace Failure
We’ve already mentioned that a clogged filter can put excessive strain on the system, which can lead to excessive energy bills. What we haven’t mentioned is that this strain can also cause the system to wear out prematurely and eventually fail. And a brand new HVAC system can cost anywhere between $4k and $12k.
So ask yourself: Do you really want end up with a $12k expense just because you delayed replacing a filter that costs around $40?
Frozen Coils
Another important component of an HVAC system is the evaporative coils. They play a major part in removing heat from the cool air that the system delivers to your home. When the air filter is clogged, it prevents air from flowing over the coils correctly. This will cause the coils to freeze up and stop working, which will eventually lead to complete system failure.
