I have a Goodman GMT100-4 that I want to replace with another Goodman Furnace. What is the current model most like my GMT100-4? I want another 80% AFUE furnace.

Thank you. Is there a model that has a high and low speed blower?

They all have multispeed blowers but the blower speed is set. It can't be adjusted maually. There are 2 stage 80% models that change firing rate and blower speed based on system demand.
