When a Mini Split Is The Right Choice
- The home has no existing ductwork
- You are adding HVAC to a garage, addition, sunroom or ADU
- Some rooms are always too hot and central AC cannot reach them
- A historic home where adding ductwork is invasive
- You want true zone by zone control
- You live where a heat pump can be the main system (Florida, Southern California, Southern Utah)
How much does a mini split cost to install?
A single zone system costs $2,800 to $6,500 installed in 2026, and multi zone systems with two to five indoor heads run $6,500 to $15,000, depending on brand, zones and the install.
Does a mini split need ductwork?
No. Each indoor head connects to the outdoor unit with a small line set, which is why mini splits suit older homes, additions and garages.
Can a mini split heat as well as cool?
Yes. Most mini splits are heat pumps, and cold climate models keep heating well in freezing weather.
Do I need a permit for a mini split?
In most places yes, and we handle it as part of the installation.
How many zones do I need?
One zone per room or area you want to control separately. A load calculation of your home decides the size of each head.
These are typical ranges across our service areas. Your price depends on your equipment, your home and what the technician finds, so we explain the repair or the options and give you the price before any work begins.
