It is very crucial as a homeowner to take good care of your home and all the systems in it. And, part of your home maintenance is knowing when to reach out for professional help in case of a problem.
One of these essential systems in your home is the air conditioner. It provides you with a cool and warm atmosphere during the hot and cold days respectively. For this reason, you should certainly take utmost care of the system.
Keeping your air filter clean is one of the key aspects of maintaining your AC. Although it may seem like a small component, the air filter is vital to your AC unit’s operations. It keeps all troublesome elements from accessing the AC.
Today we look at how important an air filter is to your AC unit. Can you run an air conditioner without a filter?
We’ll get to the answer in a bit.
The Role of an Air Filter in an AC System
It is important first to understand the role of a filter in an AC. This will help us understand whether running an AC without a filter is wrong or okay.
Firstly, the filter can be equated to a sieve. Its main purpose is to screen the air circulated via the AC unit. Since most are made of fiberglass material, they can hold and capture any contaminants and particles that may access your home.
By trapping these particles, your filter can lock them out of your AC. In turn, it protects your AC components and family as well.
Some of the main contaminants include;
- Lint and fibers
- Animal and hair fur
- Wood, plaster, and metal particles
- Dirt and dust
- Microorganisms and bacteria
Is it Possible to Run your AC without a Filter?
The answer is a resounding YES! However, this will be short-lived. You can only operate your AC without a filter for quite a short period without damaging it. After just 6-8 hours, you will be in serious trouble with your AC unit.
Running an AC without the filter is worse than operating it with a dirty one. It comes with severe repercussions not only to your AC but to your finances too. You might end up digging deeper into your pockets trying to solve filter-related problems.
Top Problems of Not Using an AC Filter
- Air Quality Issues
This is one of the most common issues when running AC without a filter. There will be a major decrease in indoor air quality. This is because dust and other contaminants will become part of your home as there is nothing sieving them from the incoming air.
Dust or dirt particles can ultimately lead to the blocking of your AC system. And, poor air quality is pretty harmful to the health of your family.
- Escalating Energy Bills
If you ever think of operating your AC without a filter, always remember its effect on your energy bills. Lack of a filter brings chaos to your compressor or motor, giving your AC system a hard time maintaining coolness.
In your monthly energy bills, these hard times will be reflected. They will keep increasing as your system will require extra power to operate.
- Compressor or Motor Problems
Can you run AC without a filter? Well, before settling for this decision, think about the problem this will bring to your compressor or motor. Debris and dirt are the main perpetrators behind motor and compressor problems.
Once they get inside these two components, your entire AC system is in jeopardy. It will not function as it should.
- Water Damage
Another problem caused by running your AC without a filter is water damage. Lack of a filter to capture debris causes your condensate drain to be blocked.
The drains aid in getting rid of the extra moisture removed by your AC. The humidity will have nowhere to go, causing water damage to your unit.
- Dirty Ductwork
An air filter collects a lot of dirt and dust particles. The absence of a filter makes these particles roam freely in your AC system.
These particles will accumulate inside your ductwork, causing insufficient airflow and other major health problems.
- Freon Tubes Problem
Do you understand how your AC operates? It siphons air from the room and blows it through the copper tubes that contain Freon inside. These tubes are usually wet.
If the unfiltered air connects with these wet tubes, the dirt inside the air remains in the condensate. It also covers the blades. The efficiency of your AC unit decreases and degrades as a result of this.
- Frozen Evaporator Coils
The refrigerant is the substance found in the evaporator coils. Its main aim is to absorb heat from the indoor air and transport it to the exterior. Your AC will, in turn, blow cool air back into your house.
For your AC to be more effective, it needs to keep absorbing this heat from time to time.
And, without a filter, dust and other debris particles gang up with grime to cover your evaporator coils. This prevents the evaporator coils from absorbing the required heat, which in turn makes them freeze.
Frozen evaporator coils block your AC from blowing conditioned air. And the worst thing is that replacing frozen evaporator coils is quite expensive. Therefore, to avoid all these issues, run your AC with a filter in place.
- Inefficient Cooling and Heating
Your AC relies on a filter to get rid of any impurities trying to access it. It usually requires a filtration system for it to be efficient and clean. The heated/cooled air makes your home very comfortable.
A dirty filter makes this impossible. And the absence of a filter makes the situation even worse. In the worst-case scenario, it usually causes severe damage to the entire unit. Your freezing winter days or hot summer seasons will also be unbearable if you run your AC without a filter.
Typically, AC systems can run without a filter. But, this is inadvisable by all means. Without a filter, you are sure that your system will always require repairs or eventually replacements.
Furthermore, the lack of filters in your AC can cause health problems such as asthma and allergies brought about by dirt, dust, or debris particles. Of course, the negatives of lacking a filter will always outdo the positives. So, let your AC operate with a filter at all times!
