What happens when your HVAC filter is clogged?
The blower fans within an HVAC system push the air through the filter. If the filter is clogged, the blower has to work harder to pass the air through the clogged filter. This results in hot and cool spots throughout the home and the inability to reach the desired temperature levels.
What happens if you don’t change your air filter?
According to the Department of Energy, clogged filters can use up to 15% more energy. As the air filter becomes more and more clogged, the inefficiency increases rapidly until the filter is changed. During the hot weather when you’re cooling your home, a clogged air filter can cause the evaporator or cooling coil to freeze.
Can a dirty air filter impact the life of your air conditioner?
Read on to learn more about how a dirty, clogged air filter impacts the life of your air conditioner. The air filter that comes standard with your air conditioner stands between the intake air register and your HVAC system. Therefore, a clogged up air filter prevents air from circulating through the vents as it should.
Why does my air filter get dirty so quickly?
When your filter gets dirty you change the pressure inside the system and by doing so you change the amount of airflow flowing through the air handler and ductwork. There are other ways to change this pressure inside the ductwork such as closing off too many supply vents, a bad blower motor, or collapsed/restricted ductwork.
What happens if you have a dirty air filter?
Perhaps the worst thing a dirty air filter can do to your car is collapse. If this happens, the air filter can pull away from the seals — even disintegrate — spelling disaster for your engine . An unsealed air filter might as well not even be there, as it allows unfiltered air into the engine.
Why do engines have air filters?
Your engine has an air filter to keep dust, particles and insects from getting into the cylinders and mucking up the works. Your engine breathes in a lot of air, and its air filter will eventually fill up with whatever dust and debris are floating around. Over time, a dirty air filter could choke your engine, even damage it.
What happens when you blow an exhaust stroke?
Compression or spark combines fuel with oxygen, causing a tiny, controlled explosion. On the exhaust stroke, the cylinder exhales nitrogen, water vapor and carbon dioxide — just like you, only hotter. Your engine has an air filter to keep dust, particles and insects ...
Does a clogged air filter slow down the flow of air?
Choking Performance. With every revolution, your engine needs to breathe; a clogged air filter slows down the flow of air. As the air filter collects more debris, air flow slows further, hindering your engine’s ability to breathe and generate power and torque. If you’re a spirited driver, a stuffed air filter will drag you down.
Can you use compressed air to clean a dirty air filter?

Does dirty air filter affect fuel economy?
Counterintuitively, dirty air filters don’t affect fuel economy or emissions on computer-controlled gasoline and diesel engines, as long as they were built after the introduction of closed-loop oxygen sensor feedback systems. Modern computer-controlled engines can adjust fuel injection to compensate for a dirty air filter, but carbureted engines depend on air flow for fuel delivery.
Can a carbureted engine be clogged with air?
Modern computer-controlled engines can adjust fuel injection to compensate for a dirty air filter, but carbureted engines depend on air flow for fuel delivery. A clogged engine air filter needs to be replaced before it damages your engine or slows you down.
Greater exposure to dust, mold, pollen and possible bacteria
This becomes more a list of medical issues rather than topics for an HVAC blog, but let’s just say dirty air filters have been linked to a greater incidence of respiratory symptoms for household residents, including, but not limited to, coughing, chronic sore throats, runny noses, sneezing, wheezing, asthma flare-ups and even low-grade fevers and headaches.
Increased energy usage and higher HVAC bills
For those family members who might remain indifferent to the possible health problems resulting from a dirty air filter, money usually talks. The reality is that a clogged air filter reduces airflow throughout your HVAC system.
Hotter or colder indoor temperatures than desired
As mentioned above, a dirty air filter means your system will not be able to regulate airflow as well as it would otherwise. Because of that, your system will not be able to heat or cool as effectively, either. Again, this is an easily fixable problem.
What are the effects of a clogged air filter?
Allergens, dust, mold spores, and other air contaminants that clogged air filters let circulate throughout the air can result in flu-like symptoms, trigger asthma attacks and other respiratory conditions, and cause chronic allergies.

What happens when a furnace filter clogs?
Therefore, when the filter clogs the air flow is minimized the blower works harder and harder to pull the proper amount of air across the coil or heat exchanger.
How does a heat pump evaporator coil freeze?
As the system airflow is reduced from a restricted and clogged filter your air conditioner or heat pump (in cooling mode) evaporator coil will begin freezing up resulting in less and less air flow from the supply vents. The refrigerant is still flowing through the coils but with no air-flow, there is no heat absorbed into the coils and refrigerant. The refrigerant falls below the freezing point. Any moisture in the air around the coil begins freezing. It effectively turns the air conditioner or heat pump evaporator coil into a freezer. If the air filter is changed then you will still have problems until the evaporator coil is defrosted. With an air-conditioner, you turn it off for several hours to allow it to thaw. With a heat pump, you can simply turn it to heat mode. It will automatically defrost the evaporator coil. However, this problem can cause serious water damage to your home or business.
What is a C filter media?
C filter media represent the HEPA filters . MERV ratings for these filters exceed MERV 13 and are the most expensive. High-efficiency particulate air filters are excellent for filtering the air but, again, they are the most expensive. An HVAC system with this type of filtering system needs to be specifically designed for this type of filter. Additionally, it is important to make sure these filters do not load up and stop airflow. As noted above, that can have a detrimental effect on your HVAC system.
What are the different types of air filters?
Mechanical Air Filter Categories 1 A1 and A2 – these are the standard 1 inch thick filters. These are typically rated MERV 1 to MERV 4. These are the least effective filters and designed for basic protection of your HVAC system and not health. 2 B filter media’s are 2 to 4 inches thick. These filters typically range from MERV 1 to MERV 12. 3 C filter media represent the HEPA filters. MERV ratings for these filters exceed MERV 13 and are the most expensive. High-efficiency particulate air filters are excellent for filtering the air but, again, they are the most expensive. An HVAC system with this type of filtering system needs to be specifically designed for this type of filter. Additionally, it is important to make sure these filters do not load up and stop airflow. As noted above, that can have a detrimental effect on your HVAC system.
What is a mechanical air filter?
Mechanical Air Filters – This is your typical off-the-shelf throw-away HVAC filter. This filter collects particles in its filtering medium. After it collects so many particles you simply remove it, throw it away, and replace it with another. Note that some mechanical filter media are washable. HEPA (High-efficiency particulate air filters) are also in this category. There are three sub-categories of mechanical air filters. These are:
Why does my AC stop cooling?
Dirty AC Air Filters cause your air conditioner to stop cooling. Clogged AC filters will cause your air conditioner to freeze up and when it thaws the water from the melting ice can overwhelm your condensate drain and cause water damage .
What Happens When an Air Filter Is Clogged?
When an air filter is clogged, the air handler must work harder to compensate for the air flow being blocked. This not only increases your energy consumption and ups your utility bill, but it can also cause the heat exchanger to overheat and shut off prematurely. If this continues to happen, there is an electronic “limit switch” safeguard in place that will fail causing the furnace not to fire up at all leading to a costly repair.
Why is clogged air bad?
Unhealthy Air: Clogged air filters allow all the dust and debris that would normally be filtered out to be re-circulated back into the home. This can result in chronic allergies and is especially dangerous for those who suffer from asthma and/or other respiratory conditions.
Why is it important to change the air filter in your HVAC system?

A Dirty Air Filter Will Hurt Your Home Comfort
The air filter that comes standard with your air conditioner stands between the intake air register and your HVAC system. Therefore, a clogged up air filter prevents air from circulating through the vents as it should. This means you will not have enough air to stay cool (or warm if we’re talking about wintertime).
A Clogged Up Air Filter Can Create AC Leakage
The way your air conditioner operates is by absorbing heat from the air inside your home. As the refrigerant evaporates within the indoor condenser unit, your system’s evaporator coil absorbs heat from the air blowing over said coil. But if the air filter is too clogged up, warm air is restricted, which will eventually cause the coil to freeze.
Dirty Air Filters Reduce AC Efficiency
When an air filter gets too blocked up, the blower fan has to run longer to try to bring in the right amount of air. Changing the air filter on a regular basis helps restore the proper airflow through the ductwork, which means more efficient AC use and lower energy bills.
