How Multi-Stage Furnaces Work
Single-stage: 100% on or completely off. Two-stage: 65% capacity most of the time, 100% for extreme cold. Modulating: continuously varies from 35-100% to match the exact heating need. The more stages, the more precisely the furnace can match your home heat loss.
Comfort Benefits
Multi-stage furnaces: run longer cycles at lower output for more even temperatures, eliminate the hot-blast-then-cold-draft cycle of single-stage furnaces, operate more quietly at low stage, and provide better air filtration (running longer means more air passes through the filter).
Cost vs Benefit Analysis
Two-stage costs $400-800 more than single-stage. Modulating costs $800-1,200 more than two-stage. In Vancouver mild climate, a two-stage furnace provides 90% of the comfort benefit of a modulating furnace at 60% of the premium. Two-stage is the best value for most Vancouver homes.
