Understanding Air Conditioner Efficiency

Every air conditioner has a Seasonal Energy Efficiency Ratio (SEER) rating.

A simple description of SEER is:

SEER = (Total cooling output over a cooling season) / (Total energy output over a cooling season)

The higher the rating, the more energy-efficient the air conditioner is. But the air conditioner that’s right for your home won’t always be the one with the highest SEER rating. The size and age of your home, how it is sited, and more, all need to be factored into the decision. Your Moore Mechanical AC tech can analyze your household needs and help you determine which energy-efficient Carrier air conditioner will best meet your needs.

If you’re interested in investing in a high SEER rating air conditioner, call Moore Mechanical at 925-307-6479 or contact us online with questions!

How an Air Conditioner Works

Air conditioners use energy to transfer heat from the interior of your home to the relatively warm outside environment. Air conditioning systems have two coils, one called the indoor evaporator coil and a second one called the outdoor condenser coil. These coils are heat transfer devices that make heat removal possible. A pump, called the compressor, moves refrigerant between the evaporator and the condenser. The pump forces the refrigerant through the circuit of tubing and fins in the coils. The liquid refrigerant evaporates in the indoor evaporator coil, pulling heat out of indoor air and thereby cooling your home. The hot refrigerant gas is pumped outdoors into the condenser where it reverts back to a liquid, giving up its heat to the outside air flowing over the condenser’s metal tubing and fins.

Common Problems with Air Conditioners


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. For room air conditioners, isolate the room or a group of connected rooms as much as possible from the rest of your home. Other common problems with existing air conditioners result from faulty installation, poor service procedures, and inadequate maintenance. Improper installation of a central 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. Air conditioner manufacturers generally make rugged, high quality products. If your air conditioner fails, begin by checking any fuses or circuit breakers. Let the unit cool down for about five minutes before resetting any breakers.

Refrigerant Leaks

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. Refrigerant leaks can also be harmful to the environment.

Inadequate Maintenance

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.

Electric Control Failure

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.

Components of an Air Conditioner

Compressor: The electric pump, or heart of the system, that circulates the refrigerant in a closed loop between the condenser and evaporator coils.

Condenser Coil: A network of tubes filled with refrigerant that remove heat from the heated gas refrigerant and convert the refrigerant into a liquid form again. The excess heat escapes into the outside air.

Fan: Pulls air through the condenser coil for heat dispersal.

Evaporator Coil: A network of tubes filled with refrigerant that remove heat and moisture from the air as the refrigerant evaporates into a gas again.

Air handling Unit: The blower and related portion of the central air conditioning system that moves air through the air ducts.

Air Filters: Air filters trap dust, pollen, and other airborne particles as air moves through the air conditioning system. Air filters contribute to both reliable air conditioner operation and health, so we dedicated a page to them

Drainage system and pan: During the normal condensation process, an air conditioner produces a significant amount of water as a by-product. In a central A/C system, there is a primary system of pipes, often made of PVC, that carry this condensate water to the outside of the building. This piping needs periodic flushing to prevent it from getting stopped up with the algae and similar growth. At a minimum, this maintenance should be done by your service company during your annual system tune-up.

SEER Ratings

Today’s central air conditioning systems are much more efficient than their predecessors. The industry uses a rating called SEER for central systems, which is an acronym for Seasonal Energy Efficiency Ratio. Essentially, a higher SEER rating means the air conditioner uses energy more efficiently. A higher SEER rating typically results in lower monthly utility bills for the owner or occupant. A central air conditioning unit rated at 13 SEER uses almost a third less electricity than a 10 SEER system. Some outside air conditioning units are rated at a range, such as 14/15 SEER, depending on what type of indoor equipment they are paired with. For example, if paired with a manufacturer recommended evaporator coil and a variable speed furnace, an outside unit could be rated as a 15 SEER system. Otherwise, the rating would be 14 SEER.
