With our steamy Connecticut summers, a central air conditioner is not just a luxury, it's a necessity. Air conditioners work hard to keep our homes comfortable, but have you ever thought about how they work? Here's a brief overview.
A typical central cooling system is a split system, meaning it consists of an outdoor unit housing a condenser coil and compressor, and an indoor evaporator coil, usually installed in conjunction with an air handler inside the house.
The compressor pumps a chemical refrigerant through the indoor evaporator coil. As warm air inside your home blows across the evaporator coil, the heat energy is transferred to the refrigerant inside the coil. It's this transfer of heat that cools the air. The heat absorbed by the refrigerant is sent outside while cooled air is blown back inside. This condensing process also removes excess humidity from the air.
A home's ductwork is designed to distribute conditioned air throughout your home, it also returns air to the air handler to repeat the process again.
The thermostat is the "brains" of the central heating and cooling system. Once the temperature is programmed, it maintains an even temperature. Some thermostats can be programmed to work on a schedule, saving energy when the house is unoccupied.
