Introduction to Air Conditioning

Air conditioning systems are a central component of modern comfort in residential homes, providing relief from the heat during sweltering summer months. As technology has advanced, air conditioning units have become a standard feature in many households, ensuring a cool and controlled indoor climate. But the question often arises among homeowners: does air conditioning use electricity? The short answer is yes, and understanding how they function can offer insights into their energy consumption.

Function of Air Conditioners

Air conditioners operate on the principles of thermodynamics, utilizing a refrigeration cycle to remove heat and humidity from indoor air. The process involves a compressor, condenser coil, expansion valve, and evaporator coil. In simple terms, refrigerant within the system absorbs heat from the indoor air and releases it outdoors, thus cooling the air inside the home.

The refrigeration cycle is as follows:

  1. The compressor raises the pressure and temperature of the refrigerant.
  2. The hot refrigerant gas then flows through the condenser coil where it is cooled and condensed into a liquid.
  3. The liquid refrigerant passes through the expansion valve and evaporates in the evaporator coil, absorbing heat from the indoor air.
  4. This cooled air is then circulated back into the room by fans, while the refrigerant, having absorbed the heat and turned back into a gas, returns to the compressor to repeat the cycle.

This process is energy-dependent, with the compressor and fans being the primary components that consume electricity. The energy efficiency of air conditioners has improved significantly with advancements in technology, leading to the development of units that use less electricity compared to older models. To assess the power consumption of air conditioners, one must consider the unit’s size, efficiency rating, and duration of use.

    After Sanford did such an impressive job installing our new Bosch furnace last winter, it was a no brainer as to who we wanted to add a central air conditioner to our house.
    They gave us two options and we chose to go with a heat pump. Jason and his team did an incredible job installing the system in just a single day. The quality of their workmanship is second to none and he couldn’t be a nicer person to work with.
    Another great job by Sanford !
