Advantages and Disadvantages of Forced Air Systems


When it’s time to start thinking about a new system for heating and cooling your home, your first thought might be central air, also known as a forced-air system. While there are a lot of advantages when it comes to central heating and cooling, there are also many alternatives you may not be considering.

Learn about the pros and cons of forced-air systems so you can familiarize yourself with different options available and which one is best for your home.

Central Air vs. Forced Air

Usually, forced air refers to the heating system and central air refers to the cooling system. In many cases, however, they are used interchangeably.

Central heating systems can refer to furnaces and boilers because the heat is generated in a central location and then distributed throughout the house.

Basically, a forced air system refers to any HVAC system that uses air ducts and vents to send temperature-controlled air into the building.

Whereas central heating can refer to a boiler system, forced air can only be a furnace or heat pump (if it uses ducts).

Central air conditioning repair services uses the delivery system of your forced air heating system to provide cool, conditioned air.

While there is a difference between central air and forced air system, the difference is small and most of the time, these terms are used interchangeably.
