Air conditioners come in many shapes and sizes, but they all work in a similar way. Air conditioners actually take heat out of a house, rather than putting cold air into the house. This process uses three basic components; evaporator, compressor and condenser. Chemicals, called refrigerants, can switch back and forth from a liquid to a gas quickly and easily in a closed system of coils. Refrigerants soak up heat inside the house and carry it outside, cooling the house in a repeating cycle.
Which kind of AC system is best for me?
In general, there are four types of central air conditioners:
Easy Installation – No ductwork to install. The indoor unit can be up to 100 feet away from the outdoor condenser and the only space required is a small hole in a wall for the copper tubing and control wiring. The condenser unit can even be positioned on a flat section of roof if available.
Quiet operation – The indoor units of these systems are typically quiet enough for libraries, classrooms, and bedrooms.
Cost effectiveness – Work well in situations where rooms only need to be cooled at certain times. For example, living rooms during the day and bedrooms at night. You save energy, since smaller fan motors are used and individual units run at different times.
Simple control – Most units come with a remote control, as well as a wall mounted thermostat, and temperature control is easy and convenient.
Attractive design – Instead of a big, clunky window unit you have air conditioning units that blend well into indoor decor. There is no need to block your windows, either.
