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?

Whether you're upgrading an outdated HVAC setup, finishing a basement, or adding a new room, mini split systems are an excellent alternative to central air. Here's why:

  • No ductwork needed – Perfect for older homes, additions, or spaces without existing ducts
  • Zoned comfort – Control temperatures independently in different rooms
  • Energy efficiency – Only cool or heat the rooms you’re using, reducing utility bills
  • Whisper-quiet operation – Enjoy a more peaceful environment compared to traditional systems
  • Modern, discreet design – Sleek indoor units blend into your décor
  • Versatile placement options – Wall-mounted, floor-mounted, and ceiling cassette units available

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.
