What are the Main Components of a Central Air Conditioning System?

Many homeowners enjoy the benefits of central air conditioning. By understanding the major components that compose the system, you can learn more about what types of maintenance and common issues require the assistance of an A/C and furnace repair company.

Air Conditioner Evaporator Coil

• Condenser and Coils: The workhorse of any central A/C system, the condenser and condenser coils are housed in an external unit installed outside of your home. This is the unit many homeowners associate with the term “air conditioner,” but it is only part of the system. The condenser is responsible for returning refrigerant to a liquid state. The heat released from this process is dissipated to the condenser coils.

• Evaporator Coils: Inside the home, evaporator coils allow the liquefied refrigerant to change into a gaseous state, at which point they absorb heat. This creates the cooling effect as well as removing humidity, “conditioning” the indoor air of your home.

• Blower Motor: Within the same area as the evaporator coils, the blower motor then distribute the cooled air throughout your home. Working together with the condenser and evaporator, this provides a complete refrigeration cycle and cooling energy for your home.

• Ductwork: The cooled air needs to be distributed, and this is where your ductwork comes in. When properly sealed, your ductwork allows for efficient movement of cooled air into areas of your home.

• Thermostat: The control unit for your central A/C system is your thermostat. Traditional models are manually set and operated, while more technologically advanced models are programmable and allow you to enjoy the maximum energy efficiency benefits of using your A/C system.

• Air Filter: The air filter in the system catches particles and dust, protecting both your indoor air quality and the blower motor components of your A/C. There are a few different varieties of filters, and you may find that high-efficiency filters work better to capture more allergens while further protecting your A/C equipment.

Programmable thermostats help your HVAC systems to run at high efficiency. These digital AC controls allow you to set weekly temperature schedules and minimize energy use. However, a programmable thermostat is only helpful if the device is set correctly. Use the following tips to set your thermostat properly and reduce energy waste around the home.

• Use Proper Installation: Installation of your programmable thermostat is important. A bad connection can make your house uncomfortable and ruin your AC’s energy efficiency. That’s why you should consider hiring a professional to install your thermostat. Even the most basic installation will require some wiring. Trust a trained expert if you feel like the repair is too much for your skill level.

• Choose A Schedule: Take your time in planning your schedule, since an accurate temperature schedule will help to maximize your power savings. Seven day models allow you to schedule each day separately, while “5+2” models allow you to group the weekdays and weekend into repeat schedules. Program your temperature to increase when the home is empty and to decrease when your family returns. These gradual changes in temperature will help to limit an overworked air conditioner.

• Optimize Your Program: A difference of one degree can make a noticeable impact on your energy bill. That’s why you should take time to optimize your programmable thermostat according to your home use and family activity. Experiment with your schedule settings to find most optimized setting for your home.

• Adjust For Vacations: Don’t forget your programmable thermostat when you leave for vacation. You can leave your home set to an uncomfortable temperature for the entire trip and save tons of energy. Remember to set the temperature schedule in the high ranges for summer vacations and to turn off the heater during winter travel.
