Central Air vs Forced Air – What Are The Difference Between These Hvac Systems

What Is Central Air Conditioner?

Cool air is circulated by central air conditioners using a network of supply and return ducts. Cooled air from the air conditioner enters the house through supply ducts and registers, which are apertures in the walls, floors, or ceilings that are protected by grills. As it moves around the house, this cooled air warms up, and through return registers and ducts, it returns to the central air conditioner.

Types Of Central Air Conditioners

There are different types of central air conditioners which are the following:

Split Systems

The most popular type of central air conditioner is a split system, and installing one in a house with a central furnace is typically the most cost-effective option. They work by separating the compressor and condenser coils, which distribute cool air throughout a home via air ducts, from the evaporator coil, which removes heat and moisture from the air. The condenser coils and compressor are often found outside of the home, whereas evaporators are typically hidden in a cupboard or a closet.

Packed central air conditioners

This system combines the evaporator, condenser, and compressor into a single unit. This system is typically installed on the roof or a concrete slab close to the house. Packaged central air conditioners function by removing warm air from the house, cooling it, and then returning it via ductwork. The system must be coupled with a set of heating coils in order to generate cool air, doing away with the requirement for an additional inside furnace.

Heat pumps

Heat pump systems, another kind of split system, are specially made to handle both warm and chilly temperatures. This system works by pumping hot air from within your house outside throughout the summer. Heat pumps draw warm air from the outside to heat the house throughout the winter. Heat pumps are often an excellent option for locations that do not frequently encounter cold temperatures because of the architecture of this device.

Ducts less mini-splits

In homes without installed ducting for central air conditioning, these ductless systems are a feasible alternative to window air conditioners. By integrating an external compressor with inside air-handling equipment, ductless mini-splits function similarly to a standard split system.

The interior units frequently have blowers connected and are set high on a wall. The interior and outdoor units are connected by tubing, and the required temperature is created by refrigerant circulation in the air. Remember that each indoor unit in this type of system is only designed to control the temperature of the space in which it is located much like a window unit.

How Does Central Air Conditioner Work?

When the indoor temperature rises above your desired set point, the thermostat turns on the system. The fan in the indoor unit pulls warm air from inside your home into return air ducts, and then passes it through filters to remove dust and airborne pollutants. That air passes over the cold evaporator coil, where the liquid refrigerant absorbs heat, changes it into a gas refrigerant, and cools the air. The blower fan then sends the cooled air into living spaces. The warm gas refrigerant travels to the compressor through copper tubing. The compressor pressurizes the gas and sends it to the condenser coil, which releases the heat outdoors and turns the refrigerant back into liquid. The refrigerant travels to the evaporator coil to continue the cycle.

Set the fan to “auto” mode if your home has central air conditioning. In other words, employ circulating fans in each room rather than the system’s main fan to create air circulation

What Is Forced Air?

Most often, you’ll hear people refer to forced air as a heating system, like one found in a furnace. Although mostly accurate, this information is really highly perplexing to the ordinary homeowner. This is due to the fact that a forced air system generally refers to any HVAC system that uses ducts and vents to bring temperature-controlled air into your house.

Unquestionably, your heater uses pushed air. If your heat pump uses ducts and is powered by electricity, then yes though mini-split ductless systems are a bit different. In reality, your central air conditioner is the same way.

What Is The Difference Between Forced Air And Central Air?

The main distinction between central air conditioning and forced air systems is that central air relates exclusively to a cooling system. The forced-air system in your house is used by a central air conditioning system to supply cooled air, using the vents, plenums, and ducts to distribute conditioned air. Using an outside unit that is not at all connected to the furnace, the central air conditioning system is separate from your furnace. But in order to supply cold air throughout your home, it effectively borrows the delivery system.

Because the distinction between the two terms is so slight, they frequently get mixed up. In actuality, the two phrases are frequently used inexactly, even by contractors.

Frequently Asked Questions

Q1. Can you add AC to the forced air system?

Ans. Yes, a forced-air heating system may be supplemented with an air conditioner. However, because it is a difficult process, we never advise you to do it yourself, you should call an expert.

Q2. How does forced air cooling work?

Ans. The forced air system employs heated or cooled air to maintain the desired temperature in your house. Your ductwork is pushed with air by a blower. Through registers, it enters your house. These registers can be found on your wall, ceiling, or floor. Your house will get at least three to five air changes every hour. Your heating and air conditioning system will be made up of a heat exchanger, an auxiliary heat kit, an air filter, an evaporator coil, a fan, a thermostat, and numerous other controls.

Q3. What is forced air heating gas or electric / does forced air heating use gas?

Ans. Gas and electricity may both be used for forced air heating. The gas-powered heating system employs a heat exchanger and burner that emits heat, whereas the electric-powered heating systems use an electric element that resembles an electric radiator.

Q4. Is the forced air heating system good?

Ans. Forced air heating is very efficient and still maintains a fair price for the level of heating that you receive. Additionally, the cost is reduced since forced air heating installation is typically less difficult than other options.

Q5. What is central air in apartments?

Ans. A system of cooled air that is delivered to one or more rooms, commonly via ductwork, is known as “central air.” If you notice a vent sunken into the floor or ceiling of the residential unit, it likely has central air.

Q6. Does this old house have central air conditioning?

Ans. Before installing the central air conditioning you should consult with an expert. The size of the AC should be according to your needs.

Q7. Is central air is same as air conditioning?

Ans. Most whole-home air conditioning systems are referred to as central air conditioners. It forces cool air into your living rooms after passing it across cold coils to replace the warm air.

Q8. Can you add central air to forced air?

Ans. Yes, a forced-air heating system may be supplemented with an air conditioner. However, because it is a difficult process, we never advise you to do it yourself, you should call an expert.
