How Does Central Air Work?
In our imperfect world, weather and temperature aren’t always in the best conditions for us. That’s why it’s important that we find our own ways to heat and cool ourselves. In today’s age, every house has a central heating and cooling system. Sometimes it malfunctions, but fixing it isn’t foreign to us. Why? Because we understand how they work. In your system, a coolant is used to change the temperature of your air. This is why your system works..
An air conditioner has 2 separate parts to it; these are called the condenser and the evaporator. The condenser is usually located on a concrete slab outside of the home. The purpose of the condenser is to condense the gases in your system into liquids. This is why there’s a condenser coil near the outside of your home: to convert the gaseous coolant back to liquid and send the excess heat to the outside.
The evaporator coil does the opposite of the condenser, converting liquids to gases. It is mounted in the plenum or main duct junction above the furnace and changes liquid coolant into a gas. This way, heat can be transferred through the system.
This is why a central air system is usually able to both cool and heat your home. By using both a condenser and an evaporator coil, your central air system is able to maintain a home’s temperature, both during the hot summer and the cold winter.
