Just wanted to get opinions on setting up the drain on these high effeciency furnaces. Some drill a hole through the floor and some guys insist on condensate pumps. Any opinions? I'm talking an unfinished basement.

Ditto.. Just make sure you pump it to a plumbing drain instead of straight outside.

How you drain is not as nearly as important as where you drain it. What ever you do avoid draining the condensate outside where it will freeze! Our first choice is always the drain for the washing machine, then a sump pump or floor drain. If it is not possible to drain it inside, then we will drain it to a 2" drain cup. If you simply run 3/8 clear tubing from the condensate pump outside, you can bet it will freeze up and may cause significant property damage.

Interesting, 2 residential companies I know out this way just drill a hole through the concrete floor and stick a 3/4 pvc in. Do you guys consider this practice a hack method? We also see this done all the time when central air is added.

Ya better have good drainage if you are going to put the A/C drain through the floor. There can be an awful lot of water come out if it is really humid in the house. May be ok for some to just drill a hole, but I prefer to use a condensate pump, they are fairly cheap and that way you know where the water is going. Also in our area we are prone to very high ground water in the spring and fall, I would prefer not to have any holes in my floor to allow water to seep in.

A hole in the floor is how my AC unit was drained. The previous owners swore they never had a problem, but as soon as I turned on the AC, I had a wet basement. Perhaps they never turned it on???
