Manual J Load Calculation
1-2 hoursHVAC contractor calculates heating/cooling loads room-by-room using Manual J methodology. Inputs: square footage, insulation R-values, window area/orientation, air leakage (blower door test), occupancy, lighting, appliances. Output: total BTU/hr heating and cooling loads. Proper sizing prevents oversized equipment (short-cycling, poor humidity control) and undersized equipment (never reaches setpoint).
Equipment Selection & Proposal
1-2 daysContractor recommends equipment based on load calc, fuel source, budget, and efficiency goals. Furnace: AFUE rating (80%, 92%, 96%), single-stage vs two-stage vs modulating. AC/heat pump: SEER/SEER2 rating, single-stage vs variable-speed, cold-climate performance. Provides itemized quote: equipment, labor, ductwork mods, permits, disposal, warranty.
Permitting & Utility Coordination
1-4 weeksContractor pulls HVAC permit (TSSA for gas work, municipal for AC/heat pump). Schedules gas disconnection if replacing furnace (TSSA requires shut-off during install). Orders equipment (2-4 weeks lead time for heat pumps). Coordinates electrical if heat pump needs dedicated 240V circuit or panel upgrade.
Installation & Ductwork Modifications
1-3 daysContractor removes old equipment, installs new furnace/AC/heat pump, connects ductwork, runs refrigerant lines (heat pump), installs condensate drain, wires thermostat, tests airflow and pressures. Ductwork mods: resizing supply/return registers, sealing leaks (30% of conditioned air leaks in typical duct system), balancing dampers, adding returns (poor return airflow kills efficiency).
Startup, Commissioning & Inspection
Half dayContractor performs startup: checks refrigerant charge (AC/heat pump), combustion analysis (furnace CO and efficiency), airflow CFM, temperature rise/drop, thermostat programming. TSSA inspects gas connections and venting. Municipal inspector verifies refrigerant certification and electrical connections. Contractor demonstrates system operation and maintenance (filter changes, condensate drain clearing).

Money-Saving Tips
Cold-climate heat pumps qualify for $3,000-$5,000 in provincial rebates — apply before installation.
Replace furnace and AC together to save $1,000-$2,000 on shared installation labour.
High-efficiency furnace (96%+ AFUE) saves $300-$500/year in gas vs a standard 80% furnace.
Schedule HVAC installation in spring or fall — summer and winter are peak seasons with higher prices.
HRV is required by code in new construction — retrofit it during renovation for better air quality.
