Question 1

What commercial HVAC system works best in Halifax?

Accepted Answer

The best commercial HVAC system for Halifax depends on your building type and size. VRF/VRV systems are ideal for multi-zone buildings like hotels and offices. Rooftop units work well for retail and warehouses. Commercial heat pumps are excellent for new construction and retrofits. Greenfoot Energy provides free assessments to recommend the optimal system.

Question 2

How much can Halifax businesses save with heat pump HVAC?

Accepted Answer

Halifax businesses typically save 30-50% on heating costs by switching to heat pump-based HVAC. Modern cold-climate heat pumps deliver 2-4x more heat per kWh than electric resistance heating, even at Halifax's winter temperatures. Exact savings depend on building size, current system, and Nova Scotia electricity rates.

Question 3

What HVAC rebates are available for Halifax businesses?

Accepted Answer

Halifax businesses can access the federal Clean Technology ITC (30% refundable tax credit on heat pump HVAC equipment), CCA Class 43.1/43.2 accelerated depreciation, Efficiency NS rebates of $200-$600/ton and the Custom Solutions Program (up to $500,000). Greenfoot helps maximize all available incentives.

Question 4

Does heat pump HVAC work in Halifax's cold winters?

Accepted Answer

Yes — modern cold-climate heat pumps with Enhanced Vapor Injection (EVI) technology operate efficiently down to -35°C. NRCan field testing confirms COP of 1.5 at -21°C, meaning heat pumps still deliver 50% more heat than electric baseboard even at extreme cold. Most winter hours in Halifax are at milder temperatures where COP is 2.0-2.5.
