What Happens if You Don't Replace Your AC Filter?

If you don't replace your AC filter, it will start to fail. You won't be able to filter the air properly, allowing dust and contaminants to enter the air conditioner. This will clog up moving parts, such as fan motors and valves, and restrict airflow, putting a strain on the system. Not changing the air filter can also have a negative impact on your health.

Dust and other contaminants can enter the air you breathe, leading to immediate problems such as headaches, itchy eyes or throat, and dizziness. If these issues persist, long-term effects could include respiratory disease, heart disease, or cancer. To avoid these risks, it's important to replace the air filter regularly and have your HVAC system inspected. Failure to change the air filter can also damage other parts of the system and result in a large repair bill in the future.

Replacing the filter on a regular basis can help preserve the life of your system and make it work more efficiently. Getting the most value out of your home is as easy as changing air filters. Homeowners who ignore filters in their heating and air conditioning systems risk increasing energy costs, damaging expensive equipment, and decreasing indoor air quality and personal health. Some ovens or air handlers have front covers that can be easily removed with a simple latch, but others require some screws to be removed.

However, some older models have air filters inside them and you may need to have the right tools to replace them. The biggest danger of not changing the filter in your air conditioning oven is that it can damage your HVAC system and reduce its lifespan. If you haven't changed your home's air filters lately, you should determine which filters you need and replace them as soon as possible. This will help ensure that the air circulating inside your vehicle's passenger compartment is largely free of pollutants and allow you to breathe more easily. In addition to damaging your air conditioning system, neglecting AC filter changes can also cause mold growth on vent covers, ducts, and inside the air conditioning controller.

If you raise your hand to several ventilation grilles and feel weak or have a complete lack of airflow, it's likely due to a clogged filter. Air filters are inserted in a specific location in HVAC systems and act as a barrier to prevent contaminants and other particles from circulating in the air or reaching sensitive parts of the system. A modern thermostat will track how often you change your air filter and remind you when it needs to be replaced. Not changing your air filter can also affect potential buyers if you're looking to sell your home. If they see that the HVAC system hasn't been properly maintained - such as signs of past leaks and dirty filters (and coils) - it could have a big impact on their attitude. When the filter is clogged, dust clumps into the evaporator coil (or coil A) of your HVAC system, which will greatly reduce its efficiency. Especially with gas ovens, this added friction and heat could even cause a house fire - fires are actually the most common safety hazard in a home. In addition to damage to your air conditioning system, not changing the filter frequently also results in a poor life experience.

Cabin air filters prevent pollution such as dirt, dust, smoke, smog, pollen, mold spores and exhaust gases from entering a vehicle's cabin through the heating, ventilation and air conditioning (HVAC) system. As a licensed home inspector, I believe that not regularly changing the filter can reduce the life expectancy of your air conditioner from 6 to 12 years. So instead of waiting to see what happens if you don't change your air filter for a long time, it's best to change it regularly for optimal performance.
