Mini Split Systems
Sizing Guide
A mini-split can cool a large house - over 3,000 square feet - if the equipment has the appropriate BTU rating. Depending on factors like geographic location, ceiling height, insulation depth, and the extent of windows, you can expect to need 25 to 60 BTUs per square foot of living space. This selector will help you figure out what size system you will need!
Step One: Choose how many zones or rooms you need to heat/cool
In most cases you will have a zone for each room, however there are instances where you can use a unit to cover several different rooms based on your home's layout.
If you are unsure how many zones you need, please contact us!

Now that you’ve selected a Mini Split System, the next step is determining how many indoor zones you need. Mini split systems come in single-zone and multi-zone options, allowing you to customize comfort in different areas of your home or business. Your choice depends on the number of rooms or spaces you want to heat and cool independently.
Single-Zone Mini Split System
A single-zone mini split system includes one indoor unit and one outdoor unit, making it ideal for heating and cooling a single room or space. This option is perfect for home offices, garages, sunrooms, or room additions where extending ductwork isn’t practical. If you only need temperature control in one area, a single-zone system is the most efficient and cost-effective choice.
Multi-Zone Mini Split Systems (2 to 5 Zones)
A multi-zone mini split allows you to connect multiple indoor units to a single outdoor unit, creating independent temperature control in multiple rooms. These systems are great for homes or businesses looking for zoned comfort without the need for ductwork.
- Dual-Zone Mini Split (2 Zones) – Ideal for heating and cooling two separate rooms, such as a living room and bedroom, or a master suite with an adjoining office.
- 3-Zone Mini Split (3 Zones) – A great solution for three connected areas, like an open-concept living space or multiple bedrooms.
- 4-Zone Mini Split (4 Zones) – Perfect for larger homes or businesses where multiple rooms need individual climate control.
- 5-Zone Mini Split (5 Zones) – The best choice for whole-home comfort, allowing up to five rooms to have separate temperature settings.
Which Mini Split System Is Best for You?
- If you need climate control for just one room, choose a Single-Zone System.
- If you need temperature control in multiple areas, choose a Multi-Zone System with the right number of zones for your home or business.
- If you want personalized comfort in each room, a multi-zone system allows independent temperature settings, making it more energy-efficient and customizable.
