Hello. I bought an Trane XR90 100k BTU furnace to replace a furnace with a cracked heat exchanger that was 150k btu & 25 years old. I had a few load calcs done & all of them came out to 100k BTU at 90% efficiency to be sufficient.
The wife is very unhappy with the new furnace as it blows air that is not nearly as warm & takes a longer time to warm up the house when going from cold to warm as we have the thermostat set to cool down at night & during the day when we are gone.
My question: Is there nothing I can do except adjust the times on the thermostat that the furnace starts up & endure the cold looks from the wife? I am thinking that the cooler air is logical given the size difference of the furnaces.
