Legal SECONDARY suiteS HVAC Calgary


One of the principal Requirements for legal secondary suites is the fire separation between the suites, especially the one regarding the ventilation system. Flames Air has lots of experience in the design and installation of secondary ventilation systems.

The two most common secondary Hvac systems available are:

- Secondary furnace system with secondary ductwork, and

- Heat Recovery Ventilator (HRV), paired with electric or boiler heated baseboard heaters

The furnace system is recommended over the heat recovery ventilator HRV system because the legal secondary suites requires additional baseboard heaters to be installed at additional cost to the homeowner.

The secondary furnace option also consumes less energy to heat the space than with a heat recovery ventilator HRV system, unless there’s a pre-existing in-floor boiler system in place already.

The price of electricity continues to rise, gas heat remains the most cost-efficient option on a month to month basis.

The HRV system proves itself to be beneficial when the house has a boiler heating system and cost is a factor during installation, but not once its occupied.

The heat recovery ventilator HRV system requires less drywall demolition in a finished basement, compare to a furnace system, HRV requires less ductwork installation.
