Get Better Control Against Weather Elements Using Ducted Air Conditioning

Ducted air conditioning is the ultimate cooling and heating solution to defy prevailing weather conditions outside your house. With a properly functioning unit, you can have cool air surround your kids as they play video games in their rooms, while still having a warmer setting for the living area. However, the cost implication, plus the disruption during installation, means that homeowners need to consider their options extensively before eventually settling on what ducted air conditioning unit to install. To help with your research, here are answers to some of the most common questions asked about these HVAC units.

What Is a Ducted Air Conditioning Unit?

Ducted air conditioning units are made to provide cooling and heating to the entire home. The systems are made up of an outdoor unit, the central indoor unit (usually found on the home's ceiling or just beneath the roof), air ducts supplying air from the central indoor unit to the air outlets installed in different rooms and sensors for each room.

Is It Worth the Cost? 

Ducted air conditioning involves a significant cost outlay, but it is a very effective cooling and heating solution. One of the other possible options to consider is the split-system AC units, but this is only appropriate when air conditioning is needed for a few key rooms. In most cases, ducted units are the best fit when many rooms are involved.

What's the Meaning of Reverse Cycle?

Air conditioning units work on the heat pump principle. Just as the name suggests, the unit works by having a fan draw warm air from the house and pass it over a cold refrigerant, found in the indoor unit. This process allows for absorption of the heat before the cooled air is redirected back to the room(s). The heat absorbed makes the refrigerant warm, and this is channelled into a compressor found in the outdoor unit. Here, the liquid is converted into a high-temperature, high-pressure gas that is then passed through a heat exchanger, where cooling takes place before the refrigerant can be channelled back to the indoor unit to absorb more heat. With a reverse-cycle unit, this process can be reversed in times when less cooling and more heating is needed.

There are many factors to consider when looking to install a new ducted AC unit to an already built house. Some of the most important considerations include the floor plan, the structure, the number of rooms, the type of construction, the placement of window and doors, the ceiling space and the number of house occupants. Professional HVAC technicians are the best people to make sense of all these factors for you. Reach out to air conditioning professionals today to learn more.
