Ductless Zoning
Zoned heating and cooling sized to each room’s BTU load, with altitude-adjusted equipment and a written estimate before anything is booked.
What Goes Wrong
The most common problems come from skipped steps at the sizing and planning stage, not from the hardware itself.
An outdoor unit sized to peak indoor heads individually will short-cycle when multiple zones run at once, cutting efficiency and lifespan.
The outdoor unit is sized to the simultaneous combined BTU demand of all active indoor heads, not each zone in isolation.
Air-source equipment loses capacity above 5,000 feet without derating, a unit rated at sea level will underperform in Aurora winters.
Equipment is selected using altitude-adjusted capacity figures so the rated BTU output holds at Aurora’s actual elevation.
Mini-split outdoor units have a minimum operating temperature; without a backup heat strategy, a cold snap can leave a zone without heat.
The unit’s low-temperature operating rating is confirmed against local historical lows, and a backup heat strategy is documented where needed.
A verbal quote that omits line-set routing, electrical work, or permit fees turns a reasonable estimate into a much larger final invoice.
The written estimate covers the outdoor unit, each indoor head model and BTU rating, line-set routing, electrical scope, and permit requirements.
System Types
From a single-room addition to a whole-home multi-zone system, the right configuration depends on your floor plan and load.
One outdoor unit paired with one indoor head, suited to a room addition, garage, or space without existing ductwork.
One outdoor unit connected to two or more indoor heads, each independently controlled and sized to its room’s BTU load.
Flush-mount indoor units that distribute air in four directions, common in open-plan spaces where wall-mount heads are impractical.
A compact air handler connects to short duct runs, delivering zoned output to rooms where a wall-mount head is not preferred.
Load calculated per room before any unit is chosen.
Permit scope identified and included in the estimate.
Dedicated circuit requirements confirmed upfront.
Each zone tested to rated output before job close.
Why Choose Us
Every step from sizing to sign-off is structured so nothing is left to a verbal agreement or a rough guess.
You receive an itemised written estimate covering equipment, installation scope, and timeline before an installer is confirmed.
A room-by-room BTU load calculation is arranged for every enquiry, no system is sized from square footage alone.
Equipment is chosen using altitude-derated capacity figures so rated output holds at Aurora’s elevation, not at sea level.
Low-temperature operating ratings are checked against local historical lows and a backup heat strategy is recorded where needed.
Each zone is tested to its rated BTU output after installation, the job is not closed until the system performs as specified.
The Process
01
Tell us about your home and we arrange a local installer to carry out a room-by-room load calculation and altitude-adjusted sizing review.
02
You receive a written, itemised estimate covering each indoor head, the outdoor unit, line-set routing, electrical scope, and permit requirements.
03
Once you approve the scope, the installer completes the work and a post-install check confirms every zone reaches its rated BTU output.
