A ductless mini-split system can be an attractive heating and cooling alternative to traditional HVAC systems. As the name suggests, it doesn’t work with ducts. Here’s more on what ductless mini-splits have to offer.
How Ductless Mini-Splits Work
A ductless mini-split system comprises an outdoor unit, indoor units in every zone you want to cool or heat, and tubing that includes refrigerant, condensate, and power. You can install as many indoor units as you need, with each unit running independently. You can mount the units high up on a wall or hang them off the ceiling. The tubing runs from the outdoor unit to the indoor ones. You’ll need to drill a small hole to accommodate the tubing. Many ductless systems can not only cool your home in the summer but also heat it during the winter.
Ductless mini-split systems have a number of advantages:
- Flexibility. Their small size makes them excellent for use as add-ons in houses with existing HVAC systems. You can use them in single rooms, including those that don’t have ductwork.
- Energy efficiency. They don’t use ducts, which can cause as much as 30% of heat loss in an HVAC system if they’re leaky. Additionally, mini-splits use variable-speed compressors, which are more efficient than the one- or two-speed compressors found in most central air units.
- Air quality. Ducts tend to collect contaminants over time. Ductless systems are, therefore, great for boosting indoor air quality.
- Zoning. With multiple indoor units, you can run one while another one is off, helping you achieve precise comfort control and huge savings.
Some disadvantages include:
- High initial cost. Ductless mini-split systems have a high initial cost.
- Aesthetics. The indoor unit can be an eyesore.
- Drainage. The units require some form of drainage. Depending on location, they can use gravity to lead the condensate to an outside drain or require a condensate pump, adding to costs, maintenance, and noise.
While ductless mini-splits may have a steep price tag, the energy savings can pay off the initial investment in the long run. Remember that ductless systems need to be installed by an HVAC professional.
