What Happens If You Don’t Change Your Air Filter?

Is it just us, or has life lately been a little hectic? It’s tempting to let little things take a back seat as your home and work routines shift and you become more cautious of germs. We’re here to remind you that it’s time to change your air filter again. It’s fine if you don’t know; simply ask an HVAC technician when they visit your home. If you neglect your air filter and allow contaminants to accumulate over time, the result is a clogged air filter. If you disregard your air filter and allow contaminants to accumulate over time, it could have serious consequences for your home, health, and HVAC system. The air filter in your home plays an important role and should be replaced on a regular basis. We’re sharing the implications of not changing your air filter because we see too many homeowners leave their filter sitting for too long.

Inadequate Indoor Air Quality

Low indoor air quality is one of the most serious effects of not replacing the air filter. As previously mentioned, your air filter plays an important role. It’s the first line of defense when it comes to maintaining safe and balanced indoor air. The majority of air filters do just as they say and trap dust, dander, and other indoor air pollutants. All those polluted particles will be free flowing in your home and in your lungs if your air filter was too full.

Utility Bills That Aren’t Typical

Your HVAC system can operate more efficiently if you have a clean air filter. Unfortunately, if your air filter is too old or dirty, it can cause your machine to malfunction. Instead, forcing air into a clogged filter makes the machine work twice as hard. This indicates that your HVAC system is consuming more energy than it should, and your utility bills are likely to be significantly higher than normal. According to, a clogged air filter can increase your energy use by up to 15%.

A Faulty HVAC System

Another effect of failing to change the air filter is equipment failure. This isn’t limited to your furnace or air conditioner; a clogged air filter can have an effect on both. Improper air flow is one of the most significant ways a dirty air filter affects the HVAC system. Both your air conditioner and furnace need adequate air flow to operate properly; a clogged air filter cuts off that vital supply. The following are some of the issues that could arise:

Evaporators That Have Ice Build Up

  • Frozen Evaporator Coils: The evaporator coil extracts heat from the air and maintains a comfortable indoor temperature. If the coils do not receive adequate air flow, the refrigerant temperature can drop too low. Condensation will form on the evaporator coil as a result of the refrigerant becoming colder than normal. This condensation has the potential to freeze over, turning your air conditioner into a block of ice.
  • Damage To The Compressor: Your air conditioner is still working to keep your home at a comfortable temperature. To reach the required temperature, it will dig itself into the earth. Your AC won’t be able to take a break if air flow is obstructed, putting a significant strain on the compressor. The compressor can completely fail as a result of this strain. Both your air conditioner and furnace are affected.  Change the air filter to prevent damage.
