Pro Tips for Accurate Sizing

  • Oversized units cycle on/off frequently, reducing efficiency and comfort
  • Undersized units run constantly and struggle to maintain temperature
  • Consider a slightly larger unit for rooms with high ceilings (over 10ft)
  • Ductless mini-splits are more efficient than window units
  • Professional load calculations account for more variables than online calculators

What is a Mini Split Air Conditioner?

Mini split air conditioners—also known as ductless AC systems—offer a modern, energy-efficient solution for both cooling and heating individual rooms or entire zones in a home or business. Unlike traditional HVAC systems that require bulky ductwork, mini splits use compact indoor air handlers connected to an outdoor compressor via a simple refrigerant line, making them flexible, efficient, and easy to install.

Why Choose a Ductless Mini Split System?

Benefits of Ductless Mini Split Systems

  • No ductwork required – Ideal for older homes, room additions, garages, apartments, sunrooms, and spaces without existing air ducts.
  • Energy-efficient heating and cooling – Mini split AC systems help reduce energy consumption by conditioning only the rooms you use, lowering monthly utility bills.
  • Zoned temperature control – Create customized comfort in different rooms with independent temperature settings for each indoor unit.
  • Quiet operation – Enjoy whisper-quiet performance compared to traditional HVAC systems and window AC units.
  • Modern, space-saving design – Sleek indoor air handlers blend seamlessly with your home’s interior design.
  • Flexible installation options – Available in wall-mounted, floor-mounted, ceiling cassette, and concealed duct configurations to fit any layout.
  • Year-round comfort – Many ductless heat pump systems provide both cooling and heating for all-season performance.
  • Improved indoor air quality – Advanced filtration helps reduce dust, allergens, and airborne particles inside your home or office.

Cooling & Heating with Mini Splits

Mini splits come in cooling-only or heat pump models. A cooling-only mini split is ideal for hot climates or spaces that don’t need heating. A mini split heat pump, on the other hand, offers both cooling and heating in a single system—perfect for year-round comfort.

From a small 12,000 BTU system for a single bedroom to a powerful 36,000 BTU unit that can cover multiple rooms, there's a size and configuration to match any space.

Is a Mini Split Right for Your Home?

Mini split systems are perfect for:

  • Bedrooms, home offices, and garages
  • Apartments, condos, and tiny homes
  • Room additions and remodeled spaces
  • Commercial offices and small shops

They're also a smart solution for supplementing your central AC or replacing outdated window units and portable air conditioners.
