What are the differences and benefits of a central air system? The best air conditioning system is the one you don’t have to think about. It comes on the moment the indoor temperature set on the thermostat requires cooling performance, and then runs quietly and efficiently when needed. But when it’s time to perform routine maintenance, make repairs or replace your system, it’s helpful to understand how an air conditioning system works.
How does a Central Air system works?
The Refrigeration Cycle
- Using electricity as its power source, the refrigerant flows through a closed system of refrigeration lines between the indoor unit and the outside unit.
- Warm air from the inside of your house is pulled into ductwork by a motorized fan.
- The refrigerant is pumped from the exterior compressor coil to the interior evaporator coil, where it absorbs the heat from the air.
- This cooled air is then pushed through connecting ducts to vents throughout the home, lowering the interior temperature.
- The refrigeration cycle continues again, providing a consistent method to keep you cool.
Pro’s: Benefits of central air systems?
- Pro: Consistent temperature all year long
- Central air conditioning helps keep your home cool and reduces humidity levels
- As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply duct-work that carries it back to rooms.
- Quieter: the compressor-bearing unit is located outside the home, the indoor noise level from its operation is lower than that of a split air conditioning
- Con: Need for ductwork: if you don’t have it yet – consider the fact installing ductwork is a major renovation that involves opening up walls and floors. Although it’ll certainly increase the value of your home in the long run, it’s a major investment that’ll require planning and a good budget.
Consider it carefully
Central air is a great choice for general comfort and energy efficiency. Multiple window units are definitely less efficient than a single, central system that controls the entire home. However, concerns over budget, ductwork installation and maintenance, and increased energy bills can be major obstacles.
