Mini Split Installation in Niagara
Ozone Climate handles mini split installation in Niagara for homes that need heating and cooling without ductwork. Ductless, heat-pump based systems that heat in winter and cool in summer, sized and placed for your home.
What is a mini split?
A mini split is a ductless heat pump: one outdoor unit connected to one or more indoor wall units. Each indoor unit heats and cools its own room or zone, runs quietly, and is one of the most efficient ways to condition spaces a furnace cannot reach, such as additions, basements, upstairs bedrooms, home offices and homes with no ductwork at all. It is also the main tool we use for climate balancing.
- Heats and cools, so it works all year
- Single-zone and multi-zone setups
- Complements your existing furnace
- Fast, clean, minimally invasive installation
Is a mini split right for your home?
Mini splits solve specific problems very well. These are the homes where they earn their keep.
Homes with chronic hot or cold rooms
Houses without ductwork
Renovations, additions and sunrooms
Multi-storey properties
Home offices and workshops
Basements and rental units
Why Niagara homeowners choose mini splits
High cold-climate performance
Designed for extreme temperatures, with excellent efficiency through Ontario winters.
Precise zone control
Set each room independently. No more heating the whole house to warm one bedroom.
Quiet operation
Indoor units are whisper-quiet, and the compressor lives outside.
Efficient and cost-effective
Heat-pump efficiency at a fraction of the disruption and cost of a large HVAC retrofit.
Reliable components
Proven systems that we size, place and commission properly, then maintain.
Minimally invasive install
A small wall opening and a line set. No ductwork and no tearing up ceilings.
Mini split, furnace or central air?
They are not rivals so much as tools for different jobs. A furnace and central air condition the whole house through ducts and suit homes with good ductwork. A mini split conditions one zone at a time, without ducts, and gives each room its own control.
That is why the two often work together. Keep the furnace for the base load, add mini split zones where the house struggles, and you get comfort in every room without oversizing anything. Our assessment tells you which combination fits, including when a mini split is not the right answer. See our furnace and air conditioning services for the ducted options.
- Single-zone: one outdoor unit and one indoor unit for one problem room or open space
- Multi-zone: several indoor units share one outdoor unit, each with its own temperature
- Both are sized by load calculation, not by room size alone
Senville and the systems we install
We work often with Senville mini split equipment, including the AURA series, and we maintain and repair most makes and models. Every system is sized by load calculation, not by the size of the room alone.
- Single-zone units for one problem room
- Multi-zone systems with several rooms on one outdoor unit
- Heat-pump based for year-round comfort
- Ask us about rebates and incentives for high-efficiency heat pumps

Our mini split installation process
Not guesswork: engineered comfort.
Full home heat mapping
We measure how each part of the house actually heats and cools.
Room-by-room evaluation
Temperature, airflow and use of each space decide where zones go.
Load calculations
Correct capacity for each zone, never oversized and never struggling.
Wall and line-set planning
Indoor unit position, outdoor unit placement and the cleanest line-set route.
Clean mounting and charging
Secure mounting and refrigerant charging, with a tidy finish.
Full performance testing
Every zone tested before we hand over.
Mini split questions
Do mini splits work in Canadian winters?
Yes. Mini split systems are designed for extreme temperatures and keep heating efficiently through Ontario winters.
Can this work with my existing furnace?
Absolutely. Mini splits complement your central heating and take over the rooms the furnace cannot balance.
Single-zone or multi-zone?
One problem room usually calls for a single-zone unit. Several rooms, or a whole floor, can share one outdoor unit in a multi-zone system. The assessment decides.
How much does mini split installation cost?
Pricing depends on room count, layout and electrical access. Request your in-home climate balancing assessment for exact pricing.
How long does installation take?
Mini split installs take about one day per head, depending on the install. Installation is fast, clean and minimally invasive, and we confirm timing for your home at your assessment.
Do you maintain and repair mini splits?
Yes. We maintain and repair most makes and models, and preventative maintenance plans are available.
Are there rebates for heat pumps?
Programs change, so we check what applies to your home at the assessment. Ask us about available rebates and incentives for high-efficiency heat pumps.
