How Does Central Air Conditioning Work?

There are many different systems to keep the air in your house cool. A few different forms that air conditioners come in include wall units, window units, and portable units. Wall units are small units that slide into a sleeve built into a wall with a vent to the outside. A window unit is secured in an open window and any holes are sealed. A portable unit is a free-standing unit you can move around your house. All of these options are fairly inexpensive ways to cool the air in your home. Central air conditioning is a little bit different. It is more expensive than these other ways to air condition, but there are many benefits that make it the ideal air conditioning system that we recommend. Before your air conditioning installation, it’s important for you to understand central air conditioning to know what you’re really getting.

Central Air

A central air conditioning system is a system of ducts built into the structure of the home that provides cool and appropriately humidified air. One of the biggest advantages to central air is appearance. You don’t need a chunky unit sitting in windows throughout your house. You don’t need portable units taking up space in the home. Instead, all you really see in your main living space is vents and a thermostat! This system is typically more expensive because of all the ducts that must be installed in the home. If you’re building a new home, this isn’t such a big deal, but if it’s an older home, then central air conditioning installation will be harder.

How It Works

Most air conditioning systems are split systems. This means there is an outdoor air conditioning unit and an indoor coil. The coil is often installed on top of the furnace and can use the same duct system as the central heating system. Central air runs on electricity. It uses a compressor to pump refrigerant through the air conditioning system where it absorbs heat and moisture from the inside and releases it outside through a vent. The cooled room air is returned to the home to keep it a nice, even temperature that you set on your thermostat. If the thermostat registers an elevated temperature, the central air kicks on to return it to the preset temperature. It’s as simple as that!
