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

If you do not change the filter on your HVAC system regularly, the equipment will eventually break down. But before that happens, dirt and dust from the outside will block your system.

Air conditioning systems that aren't kept clean waste much energy and money. The high cost of energy bills and an inefficient HVAC system are the precursors to a complete breakdown. All of these indicate that it is time to get new filters.

The system will continue to malfunction and eventually fail if you do nothing. It would be best if you avoided the consequences of ignoring your air filter any longer than necessary.

The negative effects of ignoring this factor are examined in detail here. We will reveal the chain reaction of problems that can impair your HVAC system's performance and lifespan if you don't regularly change the filter on your air handler.

What Are HVAC Air Filters?

Your HVAC system's air filter is one of its most important parts. These filters keep indoor air free of allergens, including dust and pollen. This would result in clean, breathable air for your home. 

Cleaner air inside your home is possible thanks to HVAC air filters. However, it is just as important to keep your HVAC filter changed as it is to install one. Filters that need to be cleaned regularly increase your bills and reduce air quality. 

How Do Air Filters Work?

HVAC filters are typically crafted from either spun fibreglass or pleated papers. You can install these cardboard frames to keep your HVAC system and the air you breathe safe. Most air filters work in a very straightforward manner. The polluted air enters the filter on one side, while the clean air exits on the opposite side.

Put, air filters serve as a physical barrier to airborne contaminants. They get them just as they're about to go through the vent. The HVAC system's fan draws air out of the room.

When air moves through filters made of fibreglass or paper, the pollution particles are trapped and neutralised by the filters. After that, the fresh air is distributed evenly throughout the space. Most contaminants may be removed from the air inside your home by using the filters in your HVAC system. However, this is dependent on the filter that you choose to employ. 

Low-quality HVAC systems can only filter out the most minute particles, such as pollen and dust mites. Tiny airborne contaminants are no match for delicate filtration systems. Complex weaves and multiple layers of fibres work to trap and trap dust and allergens like pet dander. 

UV filters, included in some high-end air filters, are highly effective against mildew and mould growth. Your unit may be damaged if it comes into touch with mould. The interior air quality can suffer and may even trigger allergies in some people. 

How To Determine When To Replace The HVAC Filter

Look at the manufacturer's instructions to know when you should replace your dirty air filters. However, there will come a time when your heating, ventilation, and air-conditioning system will give you advance notice that the filters need to be replaced. These symptoms indicate that your air filters are already working too hard and should not be ignored.

Thanks to the cutting-edge diagnostics built into newer models, you can usually tell when it's time to replace your HVAC system. A red warning light means it's time to swap out the filters. Certain telltale signals indicate it's time to replace the filters if you're using the older versions.

Some warning signs include:

Vents Are Covered In Dirt And Dust.

There are multiple modes of operation for your HVAC system. Some methods bring in air from outside the house, filter it, and then distribute it within. Still, others continuously circulate filtered air around the house. As a result, dust and other particles accumulate, and the filter becomes clogged.

Your home's ability to properly gather the dust allowed to pass through will decrease in proportion to the degree to which the air filter is allowed to become blocked and dirty.

Therefore, the dust will accumulate within the ducting, vent registers or grilles, or elsewhere within or around your home. Because of this, excessive dust and debris are symptoms of the furnace filter being blocked.

It's possible for the chain to break because of issues with your air filters, the exterior of your home, or the ductwork. If you've changed the filters and there's still a lot of dust in the house, the problem may be draughts or holes in the ducting.

When there is a high wind, dust and debris from outside will blow in through the cracks in your windows and doors. If your ducts let in air, your ventilation system needs to do its job to keep your indoor air clean. Air and allergens are pushed through the duct leaks instead of recirculating through the filter.

Allergies

Dust and other allergens in the home might trigger respiratory allergies. Dirty air filters will cause dust to circulate throughout the house. Family members may exhibit symptoms such as coughing, sneezing, or wheezing as some of the physical manifestations of the illness. These symptoms are due to air filter dust migrating throughout the house.

The Air Conditioner Is Not Cooling The House.

An air conditioner's job is to maintain a comfortable temperature within the house. It should work perfectly under typical conditions to cool the area down. However, if your HVAC is not effectively cooling the house, it may be time to replace the filters. If this is the case, it could be because your air filters are clogged, preventing cool air from getting through.

The Unit Is Blowing Warm Air Out.

It's possible to get a heated draught from your air conditioner if you sit too close to it. You'll feel warm air blowing out when you touch the device's rear. The unit is overheating because it is working harder than usual. This is a sign that the air filters are dirty and need replacement.

What Happens If You Don't Replace Your HVAC Filter?

When it comes to maintenance, air filters are almost always ignored. This is due to the fact that most people need to be made aware of their significance and how they function. The results of neglecting to change your HVAC filter are listed below.

Increased Energy Bills

If you've noticed an increased energy bill for no apparent reason, dirty air filters could be to blame. Pollutants can build up on air filters if they need to be changed more frequently. As a result, there is a restriction in the system's ability to circulate air.

If your filters are dirty, your heating, ventilation, and air conditioning equipment will have to work harder to supply warm air to the areas of the house that require it. This causes unnecessary waste of energy and will significantly slow down your system.

Your utility or energy bills will significantly increase due to the fact that the air will be running for longer periods of time. The months with the highest and lowest average temperatures are typically the ones in which you notice these bills more.

Furnace Damage

You risk damaging your furnace if you don't change your home's air filter regularly. This means that the extra heat will melt the entire system. The expense of a new HVAC system pales compared to the cost of replacing the entire system. Do not let forgetfulness and procrastination cost you thousands of dollars; air filter replacement is cheap (less than $50).

When air filters get clogged, your heating and cooling system has to work longer and harder to keep your home comfortable. The fans are cranking to get every last bit of air out of the room. Your entire system will eventually fail from overuse. 

Inadequate Temperature Regulation

Clogged air filters will reduce the efficiency of your heating, ventilation, and air conditioning system. Because of the difficulty in generating sufficient airflow, neither hot nor cold air will reach its destination in sufficient quantities. It reduces the effectiveness of your HVAC system.

You can expect your HVAC system to work harder and for longer periods if it isn't efficient. Some rooms may get excessively warm in the summer or too cold in the winter if filters become blocked. This can put your family at risk of catching the seasonal flu.

Regular Breakdown

If you do not regularly replace your filters, you will almost certainly have to deal with frequent breakdowns. Constantly having to get your device fixed is an expensive and inconvenient hassle.

Clamped Up Coils

Evaporative coils are commonplace in HVAC systems. The evaporator coils receive air that has been filtered. They dehumidify and dehydrate the air, preventing the home from overheating. Clogged air filters prevent adequate airflow and should be replaced regularly. 

These coils tend to harden when subjected to prolonged stress. When the air filter gets clogged, the coils get clogged, and the whole system breaks down. Repairing these coils will cost more than purchasing a new air filter. 

If you have a dirty HVAC filter and are wondering what the problem is, it's probably your wallet. A good filter can cost you $40, whereas new coils can cost several hundred dollars. Changing the air filters regularly will help you save both money and effort.

Health Concerns

The purpose of an air filter is, of course, to shield you from harmful dust and pollution. Filters that are clogged are hazardous to your health because they cannot do their job. Air conditioning and heating systems will only work correctly if their filters are clean. As a result, the polluted air can readily be reintroduced into the system.

When you neglect to replace your air conditioning filter for a few months, you'll quickly begin to experience some serious health consequences. The symptoms include achy eyes, a scratchy throat, and disorientation. Your family's health is at risk if the air filters aren't regularly changed. 

A dirty HVAC filter is linked to an increased risk of cancer, in case you were wondering what the problem is. Respiratory and cardiovascular illnesses are additional long-term complications.

Evaporator Coils Damage

The evaporative coils in your air conditioner are responsible for eliminating the heat from your home. Evaporator coil failure is inevitable if air filters are not changed regularly. These coils play a significant role in the operation of your air conditioner; thus, their replacement may be costly.

Mold And Moisture Contamination

There should be an improvement in comfort level once high-quality air filters are installed, and allergens and spores are removed. If you go without replacing these filters for a few months, condensation may form inside your ducts. 

This condensation can lead to mould growth inside the duct and, eventually, an infestation. There are between five and seven air changes each day that occur in these conduits. Whatever is in the duct will be returned with the recirculated air. It will cause allergens like mould and pollen to spread rapidly across your home. 

If you have a dirty HVAC filter and are wondering what the problem is, it's probably mould or allergies. As a result of these allergies, you may experience symptoms including a stuffy nose, itchy eyes, a rash, or trouble breathing.

Reduced Indoor Air Quality

Cleaner air is produced using the HVAC system's filters, which trap dust and other particles. If your air filters are dirty, they won't be able to do their job properly. Since dust particles can easily pass through the vent, they will spread throughout the home. 

Indoor HVAC system components are vulnerable to contamination by airborne contaminants. Poor indoor air quality can worsen preexisting respiratory conditions like asthma and allergies and impact cognitive abilities.

Components Will Not Last Any Longer.

When your filtration system loses efficiency, it has far-reaching consequences beyond a higher electrical bill. Other moving parts in the HVAC system would be harmed if dust got into the ducts. They'll operate more slowly and consume more electricity. 

When the filtration system is overused, all parts degrade more quickly than when used normally. A well-maintained HVAC unit can last as long as 20 years. Your HVAC system will only last half as long if you don't change the air filters periodically. 

Wear and tear happen if you don't change your HVAC filter. It can be costly to replace the many parts of a filtration system.

How Do You Change Your HVAC Filter?

Knowing how a dirty HVAC filter can affect your home, you may feel compelled to have it serviced immediately. Filters can be changed by an HVAC expert if they become blocked. Or you can follow these easy instructions and do it yourself. 

• Find the air conditioning or furnace filter first. The air filter for a heating and cooling system is typically located close to the blower.
• Your filter may have open access or a metal frame, depending on your setup. If the hooks or screws are hidden, you'll need a screwdriver to remove the covering.
• Once you've found the right replacement, move on to that. Depending on the requirements of your home, you should select an air filter of the appropriate size for your HVAC system.
• To read the size printed on the side of the filter, you must turn it on its side. You can get a new filter at the store, but it's better to plan and invest in high-quality filters to ensure your home's air remains pristine.
• Turn off the filtration system before replacing the filter. Protect yourself from harm and keep dust out of the duct while you work.
• Slide the old filter out from behind the metal panel.
• The new air filter should be installed in the direction of the arrow. Keep the arrow pointed away from the air return vent at all times.
• When the filter is in the right place, slide it back into its slot and fasten the metal panel.
