How a Dirty Air Filter Impacts Your HVAC System

Your HVAC system’s air filter is one of the most essential parts of the entire air conditioning and heating process. A clean air filter is the key to increasing AC efficiency and making sure your system properly controls the climate inside your home. First, though, it is important that you understand why the filter is so important. Your HVAC system works by drawing in air, which is then heated or cooled accordingly. That air then travels through the ductwork and throughout your home. Before that air enters the HVAC system, it is passed through a filter that catches pollutants, dust, dander and a number of other airborne particles. If you don’t change the filter on a regular basis, a number of things can happen. Here is how a dirty air filter impacts your HVAC system.

One of the biggest impacts of a dirty air filter is that your HVAC system will start to slow down, which can cause the entire system to work harder than necessary to properly heat and cool your home. Eventually, this will start to cause your energy bills to rise. When it comes down to it, a higher energy bill means a larger carbon footprint.

Another big impact of a dirty filter is that that your HVAC system won’t be able to properly heat or cool your home. When the filter is dirty and the system is slowed down, the air won’t be able to properly transfer through, which will affect the conditioning process. Plus, condenser coils will be too dry to turn the air into cool air for the AC process. All of these issues will result in not being able to control the climate inside your home, which can be quite uncomfortable in the extreme heat of the summer and the brutal cold of the winter.

Next, a dirty air filter may also be causing dirt, dander, mold and other allergens to get built up inside the ductwork of your home. The ductwork is responsible for carrying clean warm or cool air to all the rooms inside your home. However, if there are pollutants, you could risk spreading them throughout your home, which could severely decrease the quality of the air inside your home. If you have allergies or asthma, air that is saturated with dust and dander can cause attacks and breathing difficulties. Moreover, mold can spread and start to affect the structural quality of your home.

Lastly, a dirty HVAC air filter can result in a number of problems and issues later on down the line – issues that could be expensive and frustrating. When it comes down to it, a dirty air filter can also cause mechanical difficulties in your HVAC system, which could be exorbitantly costly to fix. In order to prevent all of these issues, all you have to do is pop out your old filter and pop a new one back in – it is as easy as that. Most HVAC specialists recommend that you swap out your old filter for a new one on a monthly basis.
