Furnace-buyer's remorse?

The geothermal furnace is finally hooked up.  It isn't any less noisy than the previous one.  It is a different kind of heat.  A more constant temperature with less extremes.  The drawback is the air which does come through the vents is not as warm.  So much for putting my pjs over the register to warm them up before putting them on for bed. I think it will take some getting used to, but it will be nice to have air conditioning in the summer.  Strange thing to be thinking about when the temperatures haven't been above freezing for the last week.
