Do You Need a Ductless HVAC System?

Conventional ducted commercial and residential AC and heating systems have done a great job over the years. Along with technology, these systems have made great improvements over the years. However, they’re not your only option if you need heating and cooling for your business or home.

You’ve probably heard about ductless mini-split systems or heat pumps. These units have gained traction with homeowners who are adding on to their homes. They’re also popular with those who are converting a garage or another area into a living space or home office, particularly now that more people are working from home. However, many homes and businesses are equipped with mini-split systems as well and are completely ductless. The question is, should you go ductless and buy a mini-split system?

Here are the pros and cons of ducted and ductless HVAC setups:

Ductless Pros

The setup of a ductless mini-split air conditioning system or heat pump includes two separate units connected together by a refrigerant line. The compressor is installed outdoors and the “wall cassette” is installed on the interior side of an exterior wall. It requires only a small hole to be drilled through the wall, so air leaks and security aren’t an issue. Heat pumps are typically quiet, and their design is less imposing. The best part is that they’re known for their energy efficiency.

Ductless Cons

If you want to go ductless, you’ll have to be willing to spend a bit more than you would on, say, a window air conditioner. In addition, the wall cassette protrudes from the wall, which may not be aesthetically pleasing for some home or business owners. You might forget that it’s even there after a while, but it can still take some getting used to.

If winters in your area are extremely cold, a mini-split system might not be the best option for your primary source of heat. If this is the case, it’s a good idea to have a separate primary heating system and use the ductless unit as a secondary heat source. This might be costly initially, but you’ll still save money in the long run because your primary heating system doesn’t have to work as hard.

Ducted Pros

A ducted system can cover more rooms over a much larger area, and there’s no apparatus protruding from the walls. Ducted systems are stronger too, so they’re the ideal primary heat source. They also work great in larger buildings, where the power of a large commercial AC is a more efficient option.

Ducted Cons

These units use more energy, so they’re not as energy efficient as their ductless counterparts. It’s also possible that you’ll end up wasting heat or air conditioning in rooms that are unoccupied, unless you have a zoned system. Ductwork is often a primary area for air leaks, as well.
