air conditioner repair

Many of us in the Bay Area depend on our trusty air conditioners to carry us through summer. These impressive machines cool and filter the air in your home, making the warmer months comfortable. But air conditioners, like any home appliance, require regular maintenance to keep performing optimally. Understanding your AC’s inner workings can help you prevent the need for an air conditioner repair later on.

Check out our guide to the anatomy of your air conditioner!

Basics

First, it’s important to understand that your air conditioner is made up of a few main components: the “cool” side that blows conditioned air through your home and the “hot” side that expels hot air outside. This process actually removes heat and humidity from the indoor air, then ‘returns’ the cooled and dehumidified air to the inside of your home. When you set the thermostat, this cycle of cooling and expelling hot air repeats until your home reaches the desired temperature.

A chemical called refrigerant is the lifeblood of your AC that makes the cooling process possible. This refrigerant travels through the mechanical components of the air conditioner: the compressor, condenser coil, and evaporator coil. As this chemical absorbs heat, it transforms from a low-pressure gas to a high-pressure liquid. Let’s take a closer look at the mechanical components that make heat transfer possible.

Cooling Compartment

The condensing unit is housed outside of your home. This is where the unwanted heat that has been drawn out of your home is expelled. In this unit is a compressor, which raises the temperature and pressure of the refrigerant gas and sends it to the condenser coil. In the condenser coil, the refrigerant is converted to a liquid state. Then, the liquid refrigerant is sent indoors to go through its cycle in the cooling compartment. After the cooling process, the now gaseous refrigerant is sent back outside to the compressor, where it releases heat until it returns to a liquid state.

Condensing Unit

The condensing unit is housed outside of your home. This is where the unwanted heat that has been drawn out of your home is expelled. In this unit is a compressor that raises the temperature and pressure of the refrigerant gas and sends it to the condenser coil. In the condenser coil, the refrigerant is converted to a liquid state. Then, the liquid refrigerant is sent indoors to go through its cycle in the cooling compartment. After the cooling process, the now gaseous refrigerant is sent back outside to the compressor, where it releases heat until it returns to a liquid state.

Expansion Valve

The expansion valve lies between the indoor and outdoor unit and regulates refrigerant flow between the compressor and evaporator. After the hot liquid refrigerant leaves the condenser, it is too hot to enter the evaporator coils. The expansion valve depressurizes the refrigerant, which helps cool it down before sending it to the evaporator in your home.

There you have it – the anatomy of your air conditioner! We hope this guide helped you understand the process behind the mechanism that cools your home.
