does air conditioning go through furnace filter

Full Answer

What happens if you install a furnace filter the wrong way?

Furnace filter that’s installed in the wrong direction will cause inefficiency. The air will have to pass through the filter through the less porous side. This will make it more difficult for your air handler to keep air flowing through the filter, which will force your furnace to work harder and use more energy.

Is a furnace filter the same as an air conditioning filter?

Is a furnace filter the same thing as an air conditioning filter? The answer to this question is YES if your house or home has central heat and air conditioning. It is also YES if your house or home has a separate cooling (HVAC or AC) unit and heating (furnace) unit as they both typically share the same air-handler.

How does an air filter work in an air conditioner?

The air filter in your HVAC system works to remove particles from the air in your home and to keep your air conditioner and furnace running smoothly. Eventually, your filter will accumulate a lot of dirt and debris and will need replacing.

Can I use the same air filter for my heating and cooling?

It is also YES if your house or home has a separate cooling (HVAC or AC) unit and heating (furnace) unit as they both typically share the same air-handler. Since the air-handler is the exact area your air filter resides, both systems share the same filter.

Does furnace filter affect air conditioning?

Many people wonder, “Can a dirty air filter cause my AC not to cool?” The simple answer is yes – a dirty filter can create several problems that can hinder your unit's effectiveness.

Does air conditioning go through the furnace?

In other words, your central air conditioning system is independent of your furnace. The outdoor unit isn't connected to the furnace at all—but they both utilize the same distribution system (vents, plenums, and ducts) to cycle cool air into your home.

Where does HVAC pull air from?

The fan from the indoor unit pulls hot air from inside the house through return air ducts. This air passes through filters where dust, lint and other airborne particles are collected. The filtered, warm indoor air then passes over cold evaporator coil.

Can I replace my AC without replacing furnace?

No, you do not have to replace them at the same time although in general, it's a good idea to replace both systems at the same time. However, there are some circumstances in which it isn't necessary. There is a lot of debate about whether you need to replace your heating and cooling systems at the same time.

Why is my AC not blowing out cold air?

If your central AC is not blowing cold air, the refrigerant may be the problem. The unit could be running low and need additional refrigerant added. The most likely cause of this is a leak. A leak not only keeps the AC unit from cooling properly, but also it can cause other issues within the home.

Where is the furnace filter located?

It will either be located inside your furnace, or sometimes it is located inside of the air return vent. Before removing, take notice of the little arrow on the filter (before removing) which indicates the direction of the air flow. We recommend taking a non-erasable marker/pen and marking the air flow direction on the outside of your furnace to make sure you always remember the correct way to re-install future furnace filters. You can proceed to remove the existing filter.

Do you need a separate air filter for a furnace?

The answer to this question is YES if your house or home has central heat and air conditioning. It is also YES if your house or home has a separate cooling (HVAC or AC) unit and heating (furnace) unit as they both typically share the same air-handler. Since the air-handler is the exact area your air filter resides, both systems share the same filter. Air will flow through your air-handler whether you’re cooling your home in the heat of the summer or warming it during the winter months. It is important that the airflow not be constricted or impeded or strain will be placed on your furnace/AC unit, causing less efficiency and can eventually lead to damage to your unit.

Do older homes have central air conditioning?

In older homes, especially across the Northern states and sections of the US, many houses do not have a central heating and air conditioning system, rather they have individual wall-mounted AC units (or no air conditioning at all) and a separate furnace.

Do heat pumps have the same filters?

In many newer homes and houses and those that are located in climates that only require moderate cooling and heating, a heat pump may be installed which is your AC/heating unit. More efficient than traditional separated AC and furnace systems, the heat pump model uses the same compressor and the same air-handler. So, in this case, the answer to this question is YES once again! Your heating and air conditioning filters are one and the same.

How does a furnace filter work?

The furnace pulls in cold air from the home, warms it through a heat exchanger, and blows the heated air back into the living space. Air in the home collects dust and fibers that could harm the internal components of a furnace. The filter prevents this from happening by collecting the dust and debris before it reaches those critical furnace components. Some filter designs even capture smaller particles, such as those that produce allergic reactions in people, in order to keep the living-space air as clean as possible.

Why does a furnace filter lose efficiency?

A furnace or central air unit that has to pull in air through the non-porous side of a filter loses efficiency because it runs longer, requiring more energy. The result is a spike in the utility bill.

Why do furnaces have backwards filter?

That way, the filter does its job of preventing dust from accumulating on blowers and motors inside the furnace. While an occasional backward filter installation is not likely to cause damage to the system, it can cost you money in efficiency.

Whether furnace filters are located at the plenum inside the furnace cabinet, or at the cold air return near the ceiling, the arrows must point toward the furnace -- the direction of the airflow -- when installed.

Can a furnace filter be installed in the wrong way?

Air quality inside the living space also suffers when a furnace filter is installed the wrong way. The filter cannot capture dust particles as well when air moves through the filter in the wrong direction. That unwanted debris ends up floating in the home’s air instead of being trapped by the filter.
