A/C 101: Understanding Air Conditioners

Many people buy or use air conditioners without understanding their designs, components, and operating principles. Proper sizing, selection, installation, maintenance, and correct use are keys to cost-effective operation and lower overall costs.

How Air Conditioners Work

Air conditioners employ the same operating principles and basic components as your home refrigerator. An air conditioner cools your home with a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is usually made of copper. A pump, called the compressor, moves a heat transfer fluid (or 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 the home. The hot refrigerant gas is pumped outdoors into the condenser where it reverts back to a liquid giving up its heat to the air flowing over the condenser’s metal tubing and fins.

Types of Air Conditioners

The basic types of air conditioners are room air conditioners, split-system central air conditioners, packaged central air conditioners, and heat pumps.


Room Air Conditioners

Room air conditioners cool rooms rather than the entire home. If they provide cooling only where they’re needed, room air conditioners are less expensive to operate than central units, even though their efficiency is generally lower than that of central air conditioners.

Smaller room air conditioners (i.e., those drawing less than 7.5 amps of electricity) can be plugged into any 15- or 20-amp, 115-volt household circuit that is not shared with any other major appliances. Larger room air conditioners (i.e., those drawing more than 7.5 amps) need their own dedicated 115-volt circuit. The largest models require a dedicated 230-volt circuit.


Central Air Conditioners

Tucson Heating and Cooling - Central Air ConditionersFacts:

  • The typical central air conditioning system is a split system, with an outdoor air conditioning, or “compressor bearing unit” and an indoor coil, which is usually installed on top of the furnace in the home.
  • Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
  • Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby “cooling” the air.
  • The heat that has transferred to the coil is then “pumped” to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
  • Central air conditioning can also be provided through a package unit or a heat pump.

Benefits:

  • Indoor comfort during warm weather – Central air conditioning helps keep your home cool and reduces humidity levels.
  • Cleaner air – As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to rooms.
  • Quieter operation – Because the compressor bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.

Packaged Central Air Conditioners

Heating and Cooling Tucson - Packaged Central ACFacts:

  • Package units are unique, all-in-one systems that supply both cooling and heating equipment in one “package.” These units sit on the ground or rooftop outside of your home or business.
  • Package units come in three forms:
    • Packaged heat pumps offer heating and cooling using heat pump technology.
    • Packaged air conditioners cool your home and can heat it as well, using electrical strip heat.
    • Packaged gas-electric units offer all-in-one air conditioning and natural gas-powered furnace performance.

Benefits:

  • Space efficiency – Unlike split-system units, all components of a complete heating and cooling system are contained in one location, making package units ideal for situations in which indoor space is at a premium.
  • Energy-efficient heating and cooling performance – All Goodman package units offer 13 SEER or higher cooling performance. Our package gas/electric units offer 80% AFUE heating performance, as well.

Heat Pumps

Tucson Heating and Air Conditioning - Heat PumpsFacts:

  • Using electricity as its energy source, heat pumps are used for either the heating or cooling of your home by transferring heat between two reservoirs.
  • In the warmer months, the heat pump acts like an air conditioner, removing heat from the air inside your home and transferring it outside.
  • During colder months, heat from outdoor air is extracted and transferred to the interior of your home. Believe it or not, even a 32º Fahrenheit day produces enough heat to warm a home via a heat pump.

Benefits:

  • Year-round, energy-efficient indoor comfort for moderate climates -A central heat pump helps maintain comfortable temperatures inside your home and reduces humidity levels year-round. Homes located in regions with severely cold temperatures may either require supplemental heating or be better served with an air conditioner/furnace combination.
  • Cleaner air – As your heat pump system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply duct work that carries it back to rooms. Whenever the air conditioner is running, this cycle repeats continually, constantly filtering and cleaning the air in your home.
  • Quieter operation – Because the compressor bearing unit of the typical central heat pump system is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.
