How to Choose Between Duct & Ductless AC Systems


Your air conditioning system relies on air ducts to keep your home cool and comfortable. While these air ducts add convenience to your home, they can also be a cause for concern.

Not only are they susceptible to damage, but also they can be home to bacteria, dust, and other impurities.

So what alternatives do you have? Ductless mini split AC systems offer quality heating and cooling, without the need for air ducts.

Each system has its pros and cons, but understanding them both will help you make the right decision for your home.

If you’re on the market for a new HVAC system, but sure to read on and find out whether or not air ducts will continue to play a role in your home.

Understanding The Differences

airhandlerCentral HVAC and ductless mini split AC systems have two essential differences - air handlers and ductwork. For most homeowners, you know what your air handler is whether you know it or not.

The air handler is the larger unit that often takes up an entire closet in your home. This is where “the magic happens.” Inside your air handler are the evaporator coils that regulate the temperature of your air, and then the blower itself, which pushes air out into the ductwork.

This complex system of moving parts is what keeps your home cool and comfortable. A ductless mini split AC system instead of using a scaled-down design with built-in evaporator coils, which cool the air, and then a blower that pushes the air out into your home.

Because they do not rely on ductwork, these systems can’t cool large areas of your home, but with multiple units set up in an area, you can easily create cooling and heating zones, which are ideal for larger homes.

How Can Air Flow be Affected?


Your air ducts will directly affect the amount of air flow you get in your home. If the ducts are damaged or dirty in any way, you’ll notice:

  • Little to no air in certain areas of the home.
  • Fluctuating temperatures.
  • Higher energy bills.
  • Cold or hot spots in certain areas (an indication of a leak).
  • Poor indoor air quality.

The air ducts are the lifeblood of your system. Without them, you won’t be able to heat or cool your home. This is why ductless systems are often a popular choice for growing homes.

If you add any square footage to your property, you’ll also need to add ductwork in order to keep that area hot or cold. With a ductless system, you can easily add temperature control with less of a hassle.

Which Unit Saves Space?

compareWhen it comes to space, a ductless mini-split AC system does have the advantage. These units are small and have versatile installation options.

Your central HVAC system will always take up a large amount of space, but also they do cool a large amount of space, so it’s part of the job.

In the end, the unit you choose has to be able to keep up with the entire demands of your home, and also your budget.
