An air conditioner Undeerstanding your Understanding Ac levels with a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The Radiant health vegetables Eating for sports success condenser coils are serpentine tubing surrounded by aluminum fins.

In a High-protein plant-based diet central air conditionerHypertension and sleep apnea evaporator, ldvels, and compressor are all located in one EGCG and drug interactions, which usually is Undertsanding on Understadning roof or Uneerstanding a concrete slab next to the levelw foundation.
This type of air conditioner also is used in small commercial Understajding. Air supply and return ducts come from indoors through the home's exterior wall or roof to connect with the packaged air conditioner, which is usually located outdoors.
Packaged air conditioners often include electric heating coils or a natural gas furnace. This combination of air conditioner and central heater eliminates the need for a separate furnace indoors. An evaporative cooler also called a "swamp cooler" is a completely different type of air conditioner that works well in hot, dry climates.
These units cool outdoor air by evaporation and blow it inside the building, causing a cooling effect much like the process when evaporating perspiration cools your body on a hot but not overly humid day.
When operating an evaporative cooler, windows are opened part way to allow warm indoor air to escape as it is replaced by cooled air. Evaporative coolers cost about one-half as much to install as central air conditioners and use about one-quarter as much energy.
However, they require more frequent maintenance than refrigerated air conditioners and they're suitable only for areas with low humidity. Older air conditioners may still be able to offer years of relatively efficient use.
However, making your older air conditioner last requires you to perform proper operation and maintenance. Yearly Maintenance needs to be performed by a licensed professional.
Click Here to see our Air Conditioning Maintenance Agreement. One of the most common air conditioning problems is improper operation. If your air conditioner is on, be sure to close your home's windows and outside doors. Other common problems with existing air conditioners result from faulty installation, poor service procedures, and inadequate maintenance.
Improper installation of your air conditioner can result in leaky ducts and low airflow. Many times, the refrigerant charge the amount of refrigerant in the system does not match the manufacturer's specifications.
If proper refrigerant charging is not performed during installation, the performance and efficiency of the unit is impaired. Service technicians often fail to find refrigerant charging problems or even worsen existing problems by adding refrigerant to a system that is already full. Air conditioner manufacturers generally make rugged, high quality products.
If your air conditioner fails, it is usually for one of the common reasons listed below:. If your air conditioner is low on refrigerant, either it was undercharged at installation, or it leaks. If it leaks, simply adding refrigerant is not a solution.
A trained technician should fix any leak, test the repair, and then charge the system with the correct amount of refrigerant.
Remember that the performance and efficiency of your air conditioner is greatest when the refrigerant charge exactly matches the manufacturer's specification, and is neither undercharged nor overcharged. If you allow filters and air conditioning coils to become dirty, the air conditioner will not work properly, and the compressor or fans are likely to fail prematurely.
The compressor and fan controls can wear out, especially when the air conditioner turns on and off frequently, as is common when a system is oversized. Because corrosion of wire and terminals is also a problem in many systems, electrical connections and contacts should be checked during a professional service call.
An air conditioner's filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.
The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system's efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity.
Filters are located somewhere along the return duct's length. Common filter locations are in walls, ceilings, furnaces, or in the air conditioner itself.
Some types of filters are reusable; others must be replaced. They are available in a variety of types and efficiencies. Clean or replace your air conditioning system's filter or filters every month or two during the cooling season. Filters may need more frequent attention if the air conditioner is in constant use, is subjected to dusty conditions, or you have fur-bearing pets in the house.
The air conditioner's evaporator coil and condenser coil collect dirt over their months and years of service. A clean filter prevents the evaporator coil from soiling quickly.
In time, however, the evaporator coil will still collect dirt. This dirt reduces air-flow and insulates the coil which reduces its ability to absorb heat. Therefore, your evaporator coil should be checked every year and cleaned as necessary.
Outdoor condenser coils can also become very dirty if the outdoor environment is dusty or if there is foliage nearby. You can easily see the condenser coil and notice if dirt is collecting on its fins. You should minimize dirt and debris near the condenser unit.
Your dryer vents, falling leaves, and lawn mower are all potential sources of dirt and debris. Cleaning the area around the coil, removing any debris, and trimming foliage back at least 2 feet allow for adequate airflow around the condenser. The aluminum fins on evaporator and condenser coils are easily bent and can block air-flow through the coil.
Air conditioning wholesalers sell a tool called a "fin comb" that will comb these fins back into nearly original condition.
An enormous waste of energy occurs when cooled air escapes from supply ducts or when hot attic air leaks into return ducts. For central air conditioning to be efficient, ducts must be airtight. Hiring a competent professional service technician to detect and correct duct leaks is a good investment, since leaky ducts may be difficult to find without experience and test equipment.
Ducts must be sealed with duct "mastic. Obstructions can impair the efficiency of a duct system almost as much as leaks. You should be careful not to obstruct the flow of air from supply or return registers with furniture, drapes, or tightly fitted interior doors. Dirty filters and clogged evaporator coils can also be major obstructions to airflow.
The large temperature difference between attics and ducts makes heat conduction through ducts almost as big a problem as air leakage and obstructions. Ducts in attics should be insulated heavily in addition to being made airtight.
Air conditioners are rated by the number of British Thermal Units Btu of heat they can remove per hour. Another common rating term for air conditioning size is the "ton," which is 12, Btu per hour. The size of an air conditioner depends on:.

Signs of Low Refrigerant A low refrigerant level is a much more common problem than a high refrigerant level in an air conditioner.
