Hybrid / dual-fuel heat-pump system

Coordinate heat pump, backup appliance, switchover temperature, electrical capacity, fuel and tariff without conflicting control strategies.

VERT / GREEN

Document appliances, fuels, thermostats and switchover logic.

JAUNE / YELLOW

The best switchover point depends on building, equipment, climate, cost and current program/tariff.

ROUGE / RED

Combustion, venting or electrical alterations remain regulated work; verify current tariff eligibility rather than assuming it.

Project triage

Heat pump + fuel furnace
Verify capacity, controls and switchover sequence. Tariff/program cited in quote
Recheck current conditions with the utility. Venting/combustion altered
Use required professionals and verify CO/combustion air. Control logic documented
Keep settings, thresholds and commissioning results.

What the professional checks

HVAC specialists and required trades verify capacity, controls, combustion/electrical work and interaction with current tariff/program.
