Home Cooling System
Whether youve got a room air conditioner or a central air conditioner, youve got one of the luxuries of modern life, now almost taken for granted. But you dont take it for granted when it doesnt work.
With the cooling season here, there are steps homeowners can take to help keep their AC up and running. Moreover, performing this simple maintenance can help lower your electricity bills.
Your air conditioner is a mechanical system, like a car. It likewise needs regular maintenance. You can do some of it if you have a little knowledge; for the more complicated stuff, call a professional contractor.
Dave Yates has done his share of room unit repair. His company, F.W. Behler Inc. in York, Pa., fixes up old "window shakers
customers ask to have taken away and installs them as temporary cooling for central system customers.
Yates offers this consumer maintenance advice for window air conditioners:
Filters: "These must be cleaned, washed or replaced a minimum of once a season,
Yates says. "Pets or dirty air will necessitate more frequent cleaning or changing.
The beginning of the season is a good time to remove last seasons dirt.
Filters typically are held against the evaporator coil behind the front cover. Front covers usually are removed by exerting downward pressure along their top and pulling the cover away. That normally exposes the filter media. Some higher-end models will have filters that can slide down and out for easy cleaning.
Coils: Yates says your best bet is to wash them outdoors with a hose, using a mild detergent. (Note: Installations vary greatly. If your room unit is removed from the window at the end of the season, coil cleaning is easier to do. If it is installed high up in the wall, you may want to think twice about removing that unit for coil cleaning. In all cases, take proper safety precautions for lifting and the use of ladders.)
To clean the coils, first remove the outer casing. Larger units will slide out of the casing.
Water should be directed through the coils in the opposite direction of airflow first, to dislodge and flush away larger particles. A garden hose set on gentle spray is the best place to start, Yates says. High-pressure jets may flatten aluminum fins, causing future airflow problems.
There are two coils in your unit: the evaporator coil, which doesnt have a filter, and the condenser coil, which does. The condenser coil gets dirty because smoke, cooking fumes and other contaminants penetrate the filter over time, Yates says.
Because evaporator coils dont have filters, "they can really get clogged up over time,
Yates says. "They are subject to all kinds of pollutants -- barbecue soot and grease, airborne dirt, leaves, grass clippings, bugs, cobwebs -- you name it.
Coil cleaners are made to dissolve these types of accumulations, but Yates urges caution; these cleaners often contain chemicals like hydrofluoric acid, which is absorbed readily through the skin and can even attack bone marrow. Respiratory, skin and eye protection are necessary. Thats one reason for removing the unit to clean it, Yates says, and a reason to consider leaving the more intense coil cleaning to a professional, both for room units and central AC.
Once they are cleaned, the coils should be allowed to dry before you reinstall the outer casing and put the unit back in the window. Moisture can help breed undesirable air contaminants on coils.
To keep your unit running well, follow these rules:
. Make sure the installed unit is tilted so that it drains outside.
. Visually inspect the slide louvers before installing for the season. Replace them before they split.
. Inspect the gap below the unit and window frame along the interior. Seal it with foam or other suitable blocking material to prevent the influx of outdoor air.
If your unit isnt working, "its either electrical, mechanical or Freon related,
Yates says. "If its not a fuse or breaker, Id suggest [consumers] pull the unit and take it to be serviced.
If the problem is with the refrigerant, youll need the services of someone licensed to handle the gas and who has the know-how to properly service the unit. Even so, it may cost more to fix a refrigerant problem than to purchase a new unit.
Central AC: Use Caution
Because of the greater complexity of central air conditioning and the risks of damaging the equipment or home, voiding warranties, and even hurting themselves, homeowners should approach maintenance here with great respect.
Still, some central AC maintenance items are too often ignored, damaging system performance and shortening system life. Howard Leonard, president of Total Tech HVACR Training of Phoenix, offers these maintenance tips with a caveat: Be careful out there.
Changing the filter: If the filter is not changed often enough, it can lead to mechanical problems that are truly monumental. A "loaded
filter will not allow any air to pass through; that air is necessary to the operation of components downstream. It is not unheard of to have to replace a central AC system years ahead of its normal lifespan because the filter was never changed.
"When installing a filter, ensure that the arrow printed on its edge is pointing downstream,
Leonard says. If the filter is in the return grille, leave the fan running to help keep the old and the new filter in place during the operation. If the filter is not in the return grille, cut the power to the air handler or furnace before proceeding.
When changing the filter in a furnace -- remember, the furnace and central AC share the ductwork and blower motor -- "it is particularly important to ensure that the blower door is secured properly after the job is complete, to prevent it from coming loose later and causing a health hazard,
How often should you change filters? That depends on conditions in the home. Anyone smoke? Do you have pets? If so, change the filter every two or three months. Higher efficiency filters (electrostatic, pleated and other filters used to improve air quality) also should be changed more often.
Oiling the indoor motor: Always power down the equipment first!
There are two types of indoor blower motor assemblies: direct-drive and belt-drive. "Belt-drive motors are relatively easy to oil because the motor is easily accessible by simply removing the blower access panel,
Leonard says. The oil ports are located on each end of the motor. A couple drops per year are all that is necessary.
Direct-drive blowers have a motor located within the blower. On some systems, these motors can be oiled easily, but often they must be removed from the cabinet. This sometimes requires disconnecting or cutting the wires that power the motor. (Remember that warning about power?)
Once access has been gained, the motor can be oiled using a telescoping oiler that can be purchased at most hardware stores. Again, make sure the blower door is secured properly after the job is complete.
Oiling the outdoor motor: Again, shut off the power. "Oiling the outdoor motor is simpler than the indoor motor,
Leonard says. "Find the simplest way to gain access to the motor and place a couple of drops in each oil port. In many cases, however, there is a risk of damaging the outdoor fan blade. Be careful.
Washing the outdoor coil: With the power off once more, the outdoor coil can be washed with a garden hose from both sides of the coil. Use of a mild degreaser will help. Gaining access will often require removing the top of the housing.
Again, be careful not to damage the fan blade, and, Leonard says, "be careful to not get anything wet that has wires attached to it, such as the compressor or outdoor fan motor. This could result in an expensive repair and a potentially dangerous situation.
If there is plant matter stuck to the coil, it must be removed before water can be applied.
Keeping the outdoor unit clean: Homeowners should reduce foliage around the unit and make sure dryer vents are directed away from it. The U.S. Department of Energy advises that plants be trimmed 2 feet away from the condensing unit.
