HVAC Expert Grant Shirley Explains Ductless Mini-Split Systems in HelloNation

The Article Explains Where Ductless Systems Work Well and What Homeowners Should Consider Before Choosing One

SUMMERVILLE, S.C., Sept. 22, 2026 /PRNewswire/ -- Is a ductless mini-split right for your home? HelloNation published an article that answers this question, featuring insights from Grant Shirley of Reasonable Air LLC in Summerville, South Carolina.

The HelloNation article explains that a ductless mini-split can address heating and cooling challenges that traditional central systems may not handle easily. HVAC Expert Grant Shirley provides insights on how these systems work and where they may be practical.

According to the article, a typical mini-split system has an outdoor unit connected to one or more indoor units. Each indoor unit delivers heating or cooling directly to its assigned space rather than moving conditioned air through ducts. This approach can make installation practical where adding conventional ductwork would require major construction.

The article identifies home additions as a common use for ductless heating and cooling. An addition may not connect easily to existing HVAC equipment, particularly when that equipment was sized for the home's original floor plan. A separate system can provide temperature control without extensive changes to the central system.

Converted garages, workshops, finished basements, and attics may present similar challenges. The article notes that these spaces are often built without ductwork because they were not originally intended as conditioned living areas. A properly sized system can provide targeted comfort without extending ducts through finished walls or confined areas.

The article also describes how a ductless mini-split may help in rooms that remain warmer or colder than the rest of a home. However, uneven temperatures can result from insulation issues, air leaks, or problems with existing HVAC equipment. Identifying the cause is important before deciding whether new equipment is appropriate.

As the article explains, many systems provide both heating and cooling through heat pump technology. During warm weather, the equipment transfers indoor heat outside. In colder weather, the process reverses and moves available outdoor heat indoors.

Cold-weather performance varies by equipment, making climate an important consideration. Some cold-climate mini-splits can continue providing useful heat at very low outdoor temperatures. The article notes that certain homes and climates may still require another heat source during periods of extreme cold.

Proper mini-split sizing is another key consideration covered in the article. An undersized unit may struggle during demanding weather, while an oversized unit may cycle improperly or manage humidity less effectively. Room size, insulation, windows, sun exposure, climate, and other sources of heat gain or loss can affect sizing.

Homeowners should also consider indoor unit placement, appearance, and ongoing care. Wall-mounted units are common, though other configurations may be available. The article explains that routine filter cleaning and periodic HVAC maintenance are important for reliable operation.

The article emphasizes that ductless systems are not automatically the best choice for every property. Homes with effective ductwork and an efficient central system may benefit more from improving or replacing existing equipment. HVAC Expert Grant Shirley's insights help explain why the home's layout, comfort concerns, climate, and installation requirements should all factor into the decision.

For spaces without practical access to ductwork, the article concludes that ductless heating and cooling can provide a flexible option. Understanding the home's specific needs and selecting properly sized equipment are central to deciding whether this approach makes sense.
