The world of HVAC can be a confusing place for first time buyers, especially when trying to differentiate the two main types of air conditioning systems – ductless and central.

Most people can go 10-20 years without replacing their air conditioning system, so it is very easy to get a little behind on what new technology is available. Think about all of the differences we have in technology from 20 years ago to today – we barely even had the internet! That applies to HVAC equipment as well, the technology is much more advanced.

Luckily Delta is here to keep you informed! Here is a rundown of the major differences between the two systems.

Central Air Conditioners

This system is split into two units: the condensing unit and the evaporative unit. Warm air is cooled through the evaporator coil and then distributed throughout the house via the ductwork and vents. This way, the air is spread evenly through the house, which is the more conventional form of air conditioning. This system requires a fan powered indoor unit connected to ductwork. The ductwork is most often attached to a furnace, so the same duct works for both heating and cooling.

Advantages:

• Cheaper than ductless air conditioner up front
• Utilizes existing ducting if you have it
• Ability to have all rooms in your home cooled uniformly

Ductless Air Conditioners (Otherwise known as Mini-Split or Duct-Free Air Conditioners)

This system is also split into two units: the evaporative unit and the condensing unit. Instead of using ductwork and a separate fan powered system to distribute air throughout the house like a central air conditioner would do, a ductless system utilizes individual units throughout the home. This allows for individual controls in each room which can allow for more flexible temperature settings.

Advantages:

• Easy installation, no ductwork
• Ability to cool specific areas in your home (each room has a thermostat)
• Saves you money on your energy bill as there is no cooled air lost in the ductwork
• Quiet
• Up to 8 units indoors can be attached to one outdoor unit

One of the major differences which will decide what is better for your home is what previous work has been done. Ductless, as it implies in the name, doesn’t require ductwork. If your home doesn’t have any ductwork in place or your old ductwork is inadequate or needs to be replaced, ductless is likely the right choice for you. Installing an entire framework of ducts throughout your home can be a lengthy and expensive process.

However, if your home already has ductwork in place, it may be easier to stick with a central air conditioning system. There are plenty of high-efficiency central air systems and many of them offer rebates that could save you money on your initial purchase. Keep in mind, ductless systems can be great in a ducted house where there are rooms that suffer from poor air flow or have higher heat gains such as solariums or additions.
