Do You Need To Have A Filter At The Air Conditioning Return

Every residential and commercial HVAC system uses a filter to remove impurities that are present in the air so it doesn't accident them back into the indoor spaces and contribute to indoor air pollution. The filter too prevents particles from damaging the system.

Is It Possible to Run an HVAC Unit Without a Filter?

The curt answer is yes, your HVAC system can run without a filter. However, just considering it can doesn't mean it should. Running your HVAC unit of measurement without a filter is probably fine for a short period of time, but continuing to do then for over half dozen hours is already pushing it. Unless you want your arrangement to accident muddy air into your home or office and likewise risk dissentious the unit, running the organisation without a filter is unwise.

How a Filter Works in an Air Conditioner.

An ac system has a filter to preclude dirt and debris from entering the unit and being blown into your indoor environment. The air conditioner sucks in air from your interior environment and removes the rut from it earlier releasing it back into the room. The render vent that sucks in air has a filter, which is the but matter continuing between the make clean air that enters the unit and the dirt and debris that was present in the air before information technology was sucked in.

Without a filter, there's aught to stop grit, pet dander and other debris from entering your home. Not all of that debris will get diddled back into the air in the building. Some of it will become stuck and accumulate in the system.

When you allow cooling and heating systems to run without a filter, there are negative effects:

Higher free energy apply.If you discover a spike in your electrical bills, check the HVAC filter before calling a professional. If information technology's dirty, try cleaning information technology. Information technology might be what's causing the unit to use more energy than information technology's supposed to.

A muddied filter forces the HVAC unit to work harder than normal because it becomes more than difficult for it to suck in air. A unit that works too difficult uses more energy and is more than likely to pause downward prematurely.

Now imagine using an HVAC system without a filter. All the dirt and droppings that is sure to accumulate in the unit volition make it fifty-fifty harder for information technology to work, so it will demand more energy to reach the temperature you ready on the thermostat.

It's also possible that the unit is already damaged, which is why it's burning up more energy than it used to.

Damaged Compressor

Residential and commercial HVAC units need regular maintenance and cleaning to foreclose impairment and premature failure. Without proper cleaning and inspections, mineral scales, grime and grit will continue to build upwards on the condenser ringlet over time. A clean condenser is necessary in guild for the air conditioner to remove the heat that builds up in the organization. The unit of measurement will continue to run in an try to cool your indoor environment, only it'southward but a matter of time before the equipment fails.

Compressors fail all the time due to overheating. If in that location'southward no filter to foreclose particles from finding their way to the compressor coil, clay buildup volition occur much faster, which ways your unit is likely to neglect much sooner.

Poor Indoor Air Quality

The filter is responsible for removing impurities from the air before the HVAC system blows heated or cooled air dorsum into the building. Without a filter, dust, pet dander and other particles are free to fly around your heated or cooled space.

There are filters designed to remove the tiniest particles, even bacteria and viruses. HEPA filters are known to capture air impurities with extraordinary efficiency. Particles measuring 0.01 micron or x nanometers and above tin be captured by a truthful HEPA filter. The coronavirus responsible for the COVID-nineteen pandemic has particles with spikes that mensurate betwixt ix and 12 nanometers, which means an HVAC organisation or air purifier equipped with a HEPA filter can effectively reduce the presence of the coronavirus in the air.

An air-conditioning system that runs without a filter volition take a huge negative impact on the quality of indoor air, possibly fifty-fifty leading to the spread of disease or an increase in allergic reactions. These tin include heart and skin irritations, equally well equally flare-ups of respiratory diseases such as asthma.

Enquiry has shown that many homes and commercial spaces have air that's more than polluted than the air in the outdoor surround. Equally most people spend up to 90% of their fourth dimension indoors, this is a concerning trend. While HVAC systems equipped with clean, efficient filters aren't the simply reply to this problem, it's important that HVAC filters at least don't contribute to information technology.

Less Efficient Heating & Cooling

As your HVAC system depends on a filter to remove impurities earlier indoor air is sucked into the organization and so blown dorsum out into the room, it needs the filtration system to exist clean and efficient so the heated or cooled air tin make your commercial space or abode comfortable. A dirty filter compromises this capability. An absent-minded air filter makes the system's task even more hard, and can shortly lead to damage. If your organization gives out on a searing hot summer day or a freezing winter dark, yous'll have an extremely uncomfortable indoor feel.

Evaporator Coils Will Freeze

Evaporator coils incorporate a substance called refrigerant, which absorbs heat from your indoor air so your air conditioning system can accident absurd air back into your abode or role. They need to absorb this rut to continue functioning efficiently.

Without a filter, dust and other particles will combine with grime to cover the evaporator coils. As the coils will not exist able to absorb as much oestrus as they used to, they'll brainstorm to freeze.

Frozen evaporator coils forestall your air conditioning unit from blowing back conditioned air, which is why your home or role may still feel hot even if you crank the thermostat to the lowest possible setting.

The compressor, which pumps refrigerant through the system, can get damaged. This is an expensive part of your organization, and you won't take any choice merely to replace it if it breaks.

Fifty-fifty if your air conditioner continues to run for a while with frozen evaporator coils, y'all'll be paying more than for the energy the system uses without the benefit of a make clean, healthy Air conditioning.

Key Takeaway

Commercial and residential cooling and heating systems need a filter to remove impurities before they suck indoor air into the system and blow information technology dorsum into the areas they're supposed to oestrus or cool.

An HVAC organisation can run without a filter, but this is inadvisable. Without a filter, the system volition draw in droppings-laden air and return the same dirty air into your indoor environment, contributing to health bug. Soon, the organization will exist inundated with clay and debris, which can cause information technology to malfunction and use up more energy, which volition shorten its life.
