Should I place a filter in the unit as well? Danny, Wife and I having a few allergy problems. We have Aprilaire filters installed on both hvac units. I have made a visual inspection of vents and returns and they seem pretty clean. Recently had one of the hvac units replaced. Should I have vents cleaned? I did see grill panels with wires and tubing but nothing that looks like it belongs to a filter function. I did find filters inside the house.
I called the Goodman Mfg. I wont to know if I have a filter on my AC air handler that is located in my atac which is separate from my condenser unit. I do have two return ducts that do have filters.
My son took the filter off his AC unit. Not sure why or for how long. But the land lord says it has done damage to the AC.
Is this possible. Can not using a filter harm the unit. I believe it has only been off a couple days. Supposedly you are supposed to take out the window AC twice a year and spray coil cleaner on the inside and outside of the unit and rinse it with a water hose.
I want to change my furnace filter. I can see an air scrubber attached to the furnace….. This is a manufactured home. I do not know how old the furnace is. Not only will it improve your indoor air quality and airflow, it also wards off expensive repairs and extends the lifespan of your expensive equipment. Changing air filters is not that difficult for most homeowners, but there are usually two obstacles to getting it done:.
However, if you suffer from light to moderate allergies, you may want to upgrade your air filter or change them more often. We highly recommend setting a reminder to check your air filter every 30 days. You can tell if you need to clean or replace the air filter by removing it from its chamber and holding it up to the light.
A dirty, clogged filter is no good! Why is the number of pets important? Pets tend to shed large amounts of hair, clogging filters quickly, which in turn can severely reduce the performance of your HVAC unit. After reviewing this list of air filter locations, if you still cannot find your heating or air conditioning system air filter read our detailed instructions on how to find air filters which follows just after this list.
Photo: a ceiling return air inlet for an air conditioning system in a U. In a two-story home the contractor often locates this return centrally near the top of a stairwell. Above: this basement oil-fired heating furnace is an up-flow unit: return air from the building blue arrows moves from the building's occupied space through return ducts blue arrows into the bottom of the heater.
Watch out : We marked in yellow an unsafe return air inlet grille placed right in the basement on the reutrn air plenum itself. Someone probably added this air inlet yellow arrows to improve the total air flow through the system, but drawing return air from close to the oil or gas burner on a furnace can.
If after reading this catalog of air filter locations you still can't find your air filter, below we. Central air conditioning filters or heating system filters if hot air heat is used as well are sometimes hard to find. Here are some tips on where to look to find the filters on your central air conditioning system:. Central air returns - Air conditioning filters located on central air return registers: if the system uses one or just a few central return registers very often a filter is placed behind the inlet grille at the central air return and is easily spotted in installations such as this Arizona central air conditioning air return inlet in the ceiling of a new home - the large rectangle is a return inlet where the air filter is quite visible.
In this photo the small opening is a poorly-installed supply register - air coming out of this register will simply be drawn right back into the return air inlet and won't do much good for the rest of the building. Look for central air returns on building ceilings and WALLS [photo] in central areas such as in the ceiling near the top of a stairwell to an upper floor, or on lower floors look on hallway ceilings.
Below is a central air return on the wall of a New York home. This wall return air inlet sports a pleated air filter right behind the hinged grille opening. To minimize the airborne dust levels in this home we used. Don't forget to look for central air return registers on floors too, such as shown in this photo of a return air inlet in the front hallway of an older New York home. We noted that a bit of reduction in air flow and a bit of increase in home heating cost may be the result of leaving stuff on top of the return air inlet.
It is usually been better to put the filter at the wall or ceiling return register grille since that way the return air ducts are protected from debris accumulation. Central return registers are normally located in one or two common areas of the building where they will not be accidentally "shut off" by someone closing a door.
For example, a bedroom won't normally have a central return register since closing the bedroom door would shut off other building areas from the return air path. This photo shows what you'll see when you open a ceiling return air register and remove the filter that should have been installed there.
The duct surfaces in this ceiling look rather clean - the filter has been doing its job. You may see house dust deposits around the edges of the opening into which the air filter is mounted - showing where air bypass leaks are occurring. Some air filters include a gasket to seal these locations against air and dust leakage. Sometimes these leaky openings at air filters also cause noises when the air handler is running.
Watch out : If a building air conditioning or heating system air handler gets its return air right at the air handler such as in this. And the system will have high operating costs because the air flow is "one-way" drawing constantly "new" air from the basement into the air handler to be warmed or cooled and sent "one way" into the living area.
Return ducts should bring air from the living are back to the air handler for cooling or warming. Individual room air returns - look in each room where there is an air conditioning supply register to see if the room also contains a return air registers.
Since some rooms have multiple air supply registers and ducts we need to know how to distinguish a supply air register from a return air register. The louver notice the little lever at the right end of the register cover? But don't be confused. Air moving into a return register also may just be felt as an airflow across your hand and you may not be sure which way the air is moving. Holding a simple piece of tissue paper next to an air register will by its movement show you for sure which way the air is moving.
Once you've located the air conditioning or heating air supply registers, look in the same room to see if there are other registers that collect return air to take it back to the air conditioning air handler. Return air inlet registers are usually louvered as well, but will normally not have adjustable openings that can be opened or closed.
Main air filters are rarely installed on individual room return or supply air registers, but identifying the presence and the location of both supply and return air registers will help us understand whether or not the system uses central returns or individual room air returns, or a mix of both.
Individual air register filters : Sometimes you may see some filter like material installed right on individual air supply or air return registers in rooms. These are usually "add-on" products that occupants have installed, perhaps in complaint that the duct system itself is dirty and that central filters have proven ineffective, or people may install individual register filters out of a general anxiety about building indoor air quality.
OPINION: individual air supply or return register air filters are either ineffective not trapping much debris , or if they are effective, they are at risk of significantly reducing the air flow into the rooms where they are used, reducing the effectiveness of the cooling or heating system or increasing system operating costs. If the building duct system is so dirty that people are installing these filters it may be preferable to have the duct system professionally cleaned.
If a building uses both supply and return air registers in every room, that is, if it is not using central air return registers at just a few locations, then the air filters for the system are most likely going to be found on or very close to the individual air handlers or blower units themselves. Photo: I'm holding a bit of tissue paper in front of an air register while the furnace or air conditioner is operating.
Even a weak air flow at a register will move the tissue showing the direction of air flow. This is a supply register: the tissue is blown away from the register's opening. We would have guessed that this is a heat or cool air supply register by the presence of louvers inside of the register grille and by the control lever that can open or close them.
Operable control louvers to adjust air flow are normally found only on supply air outlets into the occupied space, while return air registers or grilles normally have no lever controls. Larger houses may have more than one system and will have separate filters for each system. In the process of replacing the filter in an AC system, you might discover a few areas that look unusual. When you pull out the old filter and see an excessive amount of dust and debris surrounding the ducts or the space behind the filter, that's a clear sign that you have clogged return ducts.
If the return ducts have too much dust, some rooms in your house may have limited airflow and more dust settling on surfaces. Want to learn more about ducts and the benefits of cleaning them? Want advice on your air filter? Schedule service today! Air handler located in the basement.
