Mini-split ductless systems are becoming a super popular option for homeowners who need a unique solution to their home’s climate control. If you’ve been considering a ductless HVAC system for your Sarasota, Florida, home, we’ve created this guide to give you all the info you need to know about these systems, so you can make an informed decision about whether one is right for you.

How They Work

Ductless mini-split HVAC systems work differently than a traditional HVAC system. Significantly smaller, these units are designed to provide climate control solutions for unique or difficult rooms and home layouts. The system itself is actually fairly simple. There are two main components: an exterior portion that is outside of the home and an interior portion, which is located in the area to be heated or cooled. The exterior part houses the compressor, while the interior has the blower and the thermostat.

The system cools by removing heat from the air via a refrigerant and replacing the heated air with cooled air. When it gets cold, the system works in reverse, pumping in hot air and removing the cold air.

One of the greatest perks of ductless systems over window-mounted units is that the system is extremely quiet, with minimal fan noise. In addition, they only require a small hole to be drilled between the interior and exterior portions, a much smaller commitment to many of the other climate control alternatives on the market.

Energy Efficiency

Because they’re relatively small and have few components, ductless HVAC systems are also remarkably energy efficient. Ductwork has a major impact on your energy efficiency, especially if the ductwork is dirty or improperly sealed. With such a huge opportunity for energy waste, even the best systems can still end up affected.

On the other hand, ductless mini-split systems have a small, closed system that has little to no opportunities for energy waste. This can lead to a significant boost in energy efficiency and a reduction in utility bills.

Ideal Situations

Ductless mini-split systems can be used as whole-home solutions. However, some of the best uses for them are for single rooms or areas in a home that are difficult to cool. New construction or conversions where ductwork either can’t be extended or is too costly to renovate are a perfect setup for ductless mini-split systems, which can be used to get climate control into those rooms. Oftentimes, these systems are far cheaper than extending ductwork.

In some cases where the addition is a significant amount of space, it may be too much of a load for the current central HVAC system to handle. A ductless system is the perfect augmentative measure to keep that new space comfortable without overloading the central HVAC.

They are also a good choice for historic homes where either there isn’t a central system or the central system only reaches the few main rooms. Ductless mini-split systems can be used as a zoning system for family members who like their room temperature to be different than the rest of the home, or to cool or heat rooms selectively while leaving the rest at a stable, low-cost temperature.

Limitations

Like any system, there are some limitations to ductless HVAC systems. They are mostly intended for room-sized spaces, which means they often can’t work for adjoining rooms or oversized spaces. In addition, due to the fact that there isn’t ductwork in place, the room has to have external-facing walls, meaning it isn’t appropriate for interior-located rooms. Some homeowners don’t like the interior portion of the ductless system. Even though modern systems are significantly sleeker and quieter than older models, it still is a unit that’s placed in a conspicuous place.

Another limitation for many homeowners is the cost. Ductless mini-split systems can be pricey, even though they often pay for themselves in energy savings. In addition, the filters on the system need to be washed or replaced monthly. They can’t handle the same buildup as central HVAC filters, and any excess dust or debris can lead to poor performance.
