The outdoor unit, of course, is installed on the outside wall of the room in which the indoor unit is located. It includes a compressor, condenser coil and the expansion coil or capillary tubing.

The indoor unit is high up on the wall and includes a cooling coil, long blower and air filter.

A split air conditioner also has a capacity between 1 and 3 tons.

3. Packaged Air Conditioner

This type of AC unit is an all-in-one heating and cooling machine.

The system's components lie in the outdoor unit, which is placed on a rooftop or at the foot of the building.

The outdoor unit consists of a compressor, electrical panel, thermostatic expansion valve, air filter, front panel and return air grill. I also includes the evaporator coil, evaporator fan and housing, as well as heating and humidifying components.

A packaged AC unit is between 3 and 15 tons.

4. Central Air Conditioning System

This type of AC unit has a central location, distributes air to and from various rooms via fans and ducts.

Homeowners choose central air conditioners to help regulate humidity and comfort throughout several rooms all at once.

The outdoor unit contains a condenser coil, compressor, electrical components and fan.

The Importance of Annual Tune-Ups

A professional bi-annual tune-up is necessary for all homeowners. It reduces the number of breakdowns of your AC, saves you money on preventable problems, and lengthens your AC's life.

First, have the system checked before its winter use, and then get your air conditioner checked just before the hot summer months.

Your HVAC professional will lubricate and inspect all system parts for functionality. In addition, they will replace filters, clean out drain holes and check your refrigerant levels.
