Condensate pump evacuation tubing

[Unclev]

Hello all,
What is the proper method for running the tubing to evacuate out of the house through the hole that the lineset goes through? I have had three different methods provided to me by three different HVAC contractors. I don't know which is correct. So what are the correct method(s). I live in PA where the temps drop into freezing for most of winter. Thanks to all the Pros that post!

What does it serve?

My original heat pump had the evap coil drain the condensate through a P trap then into a hole in the basement concrete foundation also where the heat pump is located.... (In the basement) There is a lot of Radon around here so they will no longer do that and the only approved method in our area is to evacuate the condesate outdoors. I hope this helps.

Condensate from ac is not a problem will only be during summer months, but if there is a humidifier that would run during the winter and would freeze.

I will not have a built in dehumidifier so I wonder why they are all concerned about freezing? That's what I thought too. After I stop using ac mode in Sept ac wont be used till May again. Why are all worried about freezing????

Not a "D" humidifier a humidifier that ads moisture in the winter. If you do not have then you have no problem pumping outdoors.

Opps yes I meant to say humidifier.

again, if you ONLY use this set up for the A/C condensate you have no issues.

Do you have a gas furnace? If yes. What afue?

[hearthman]

If you have a high efficiency furnace with drainage from a secondary heat exchanger or drainage from a humidifier then you should run your drainage to a slop sink or sump pump. It can drain into the DWV system if there is an air gap to a stand pipe that is trapped. Otherwise, if AC only, it can drain to the exterior without freezing hazard. Also, the condensate may be somewhat toxic or corrosive so be careful where it discharges.

Thanks again for all the replies.
I have an all electric heat pump,no furnace so I really don't know what all the fuss is about with these HVAC contractors and the condensate freezing.

because later when a humidifier is added......

I live and install both condensing furnaces and HP's with humidifiers way up here in the north country where freezing is a very real problem. Been puttin' condensing furnaces in attics for years, also with humidifiers. With a little thought, it's easy to keep the condensate from freezing. But then again, it seems most techs can't think, I reckon.
