What’s The Difference Between Central Air and Forced Air Heating?



If you live in an older home, it may be time to look into remodeling your system. If you’re not sure what is being talked about, you should ask for referrals from past clients. When they talk about the difference between central air and forced air heating, they are generally referring to this type of heating system. Central heating refers to the furnace and central air heating is generally just term used to describe a cooling system.



What’s The Difference Between Forced Air Heating and Central Air?

If you are wondering how forced air heating differs from central air heating, it is because of the method of delivery of the temperature control. Generally, central air heating systems will have ductwork that is connected to a central area that is heated through electricity or natural gas. The temperature control is usually set by a thermostat inside of the furnace. If your furnace does not have a thermostat, it will rely on the temperature control built into the heating ductwork.

The major difference between central air conditioning and forced air conditioning is the method of delivery of the temperature control. Central air conditioning systems will have ductwork that is connected to the house that is heated via electricity or natural gas. These ducts are generally located in the attic or crawl space of the home. The temperature control is also typically controlled by a thermostat that is placed in the central air ductwork. In most cases, the temperature is controlled manually or electronically depending on the model of the furnace.

On the other hand, forced air heating relies on the radiant heat coming from the installation of a heat source such as a furnace, hot water heater or a radiant ceiling fan. Because of this, the installation process of forced air heating can be much longer than that of a central air conditioner. In addition to the installation process, there will be additional heating and cooling measures done during the installation process in order to bring the house to a comfortable temperature. These additional heating and cooling measures include the weather stripping that is used around windows and doors, the installation of registers and thermostats in the rooms and ductwork and the installation of ceiling fans in each room.



Another major difference is that central air conditioners will use one or two heat pumps to move the warmed air through the house while forced air heaters will use one or two heat pumps and then distribute the heated air through the house using an air ventilation system. These systems are much more efficient than heat pumps alone, but they are not as efficient as a whole house heat pump. If you’re trying to keep your home more comfortable, and want to be sure that it stays at a comfortable temperature, choosing a central air conditioner is highly recommended. However, if you are looking for a quick and easy way to bring your home from a cold winter’s night to a warm summer’s day, a forced-air heating unit is often the best option.

Types of Forced-Air Furnaces

There are two main types of forced-air furnaces – evaporative and convective. Evaporative furnaces are most commonly used in temperate climates where the warm air coming from inside the house can’t escape into the air. These furnaces work by collecting warm air and transferring it through a cooling coil to a second or third heating coil outside of the home. The cool air is brought into the living areas through the chimney or flue. While the air does not rise to the roof of the house, the air is extremely cold and as a result chilly. Most people who use forced-air furnaces in cold climates find that they work quite well, but generally aren’t as energy efficient.

Radiant heaters work by using a combination of convection and radiant heat to transfer heat. The most effective radiant heater is a convection heater. This type of system is more efficient than an evaporative system. In fact, if all forced air heating systems were to be replaced with radiant heating systems the electricity bill would likely be reduced by as much as 40%. Because of this, convection and radiant heaters are often preferred over forced air heating systems.

If you’re in need of a portable heating device, a forced air system may be exactly what you need. Many times, people choose to use forced air heating units when they are away from home for an extended period of time. Some even choose to use forced-air units when they are camping or in an area with harsh weather. While forced-air units can be used with any type of heating unit, particularly radiant heating units, they are most often used in conjunction with central air conditioning systems.
