a. Do modulating furnaces, in general, have more repairs than 2 stage?
b. On a 1900 square foot ranch house, would the modulating unit keep the bedroom end more consistently warmer than a 2-stage? That has been a problem with the Trane 2 stage.
c. Is the Bryant Evolution 987 modulating considerably quieter than the Bryant 926 2-stage?
d. If a modulating unit runs more often, but at slower speeds for more consistent temperature, doesnt that mean there would be more wear on the parts vs a 2 stage over time?
e. What % of the market is replacing with modulating units now vs 2-stage?
Very much appreciate any input….just trying to understand if the industry truly believes the value of the modulating unit warrants its higher cost. Thank you.
