A ductless AC is different from a central air conditioning system. A ductless system is suitable for a new build or an older home without ductwork. This system works wonders to cool add-ons, garages, and sunrooms. It also allows you to personalize your climate control by focusing on a specific area of your home. This guide from Mission AC & Plumbing can help you decide if a ductless AC is right for you.
What is Ductless AC?
Basically, a ductless air conditioning system combines an indoor unit and an outdoor unit. These units are connected by wiring and refrigerant tubes, eliminating the need for a ductwork system.
Since there is no ductwork and no need for vents, you only need to install one hole in the wall. As this style of air conditioning utilizes two units, it’s also referred to as a mini-split system or simply a mini-split.
How Does a Mini-Split System Work?
This type of HVAC system couples an outdoor unit, which houses a compressor and condenser coils, with an indoor unit. The indoor unit contains an evaporator coil and a blower fan.
To cool your space, the outdoor compressor unit pumps refrigerant to the indoor unit’s coil. Heat leaves the refrigerant as it converts to gas, sending cooler air out of the indoor unit and into the space. Then the refrigerant travels to the outdoor unit and condenses back to a liquid where the outdoor coil releases the heat. A mini-split heat pump works in the same way but reversed, to deliver heated air throughout your space.
There are different options for ductless air conditioners:
- Wall-mounted units that install directly on an interior wall
- Console units if wall mounting isn’t a viable option
- Cassette units allow a unit to mount on the ceiling instead of the wall
You may choose to install a mini-split in your home if there is not enough space for ductwork. A ductless AC can also work with your existing central air conditioning system. This is a great option if your home has an add-on or your second floor’s temperature never feels quite right. It is possible to configure a ductless air conditioner to work with a central AC. Always hire a professional for any installation job.
Types of Ductless HVAC Systems
Single zone mini-split systems connect one outdoor compressor to one indoor unit. This style of ductless AC can successfully cool your home if there is adequate airflow and your home only has a couple of rooms.
If you don’t live in a small home or cabin, a single zone AC may still be a good choice for your new addition or a room that doesn’t get enough airflow – like a garage or workshop.
A multi-zone ductless AC is a system that utilizes one outdoor compressor with up to five indoor units. This type of HVAC system is very efficient, as you can fully customize your climate control in each room that has a unit.
For instance, you can opt to set different temperatures in various bedrooms and even shut the unit off in an empty guestroom. Installing a multi-zone split AC can make your home more efficient and save you money on energy bills.
Benefits of Ductless Air Conditioners
There are a number of benefits that come with ductless air conditioners, including:
- Minimal installation
- Effective heating and cooling
- Low-profile – maintains home’s aesthetic
- Customizable climate control
- More energy efficient than central AC
Common Ductless AC Myths and Concerns
There are quite a few myths out there about ductless air conditioning units. We’re here to set the record straight.
No venting needed – This type of air conditioning system does not utilize a combustion process. Since they do not create harmful gases, there is no risk of carbon monoxide entering your home. Ductless AC units do not require an outside vent installation.
Pulling outside air indoors – Split system ACs do not pull air from outside to cool your indoor space. Similar to a ducted HVAC system, ductless cooling systems recirculate air to cool your home.
Allowing allergens – Mini-split air conditioners do not introduce allergens into your home. These systems recirculate the air already in your home, not force outside air in. Also, ductless AC units include an air filter to trap particulates from the air.
