unit under a deck

[IRONHILL24]

I'm sizing a house with a small yard and I'm looking for a unit for under a deck. The only one I see that will work is a Carrier/Bryant. This unit has a horizontal discharge. I would have the fresh air from under the deck or should I put the unit in the yard? I have about 4' to the top of the deck? Any equipment recommendation?

that looks like a ductless mini split not a regular split system unit, but I am not a Carrier/Bryant expert.

I agree, it looks like a minisplit rather then a normal split

I have seen other contractors used in before but like you I'm not a Carrier/Bryant expert

Put it out in the yard. Even though air flows through the unit, putting it in a partly enclosed space is a bad idea. The temperature in the space under the deck will be as much as 20 degrees warmer than the air temperature outside. That will hurt efficiency, capacity and life of the equipment.

It's a regular split system condenser, just a small one. If you have plenty of room under the deck for airflow and service access, it should be fine.

I think its a 1 to 5 ton

Instead of writing a lot, I will include this link to an article in Contracting Business. I know the author. :-)

Kevin, We have seen lot of town homes with condenser units under decks with a drier vent next to it. What I was thinking was a side discharge.( not a top discharge) This will push the heat away from the deck and pull air from under the deck.(the air could be cooler) Are you thinking the wood will hold the heat from the sun and make my air intake hotter or were you thinking I was talking about a top discharge that will make the air going in to the condenser 20°+ warmer. I know putting a unit under a deck with a top discharge will kill a unit, but what about a side discharge?

IRONHILL24,

If the horizontal discharge unit was placed at the side of the deck so that it discharges out into the open air, and there was lattice around 3 sides of the deck to pull ambient air into the space under the deck, I would see no problem.

But if the unit was placed well back from the edge of the deck, then some of the air would recirculate, and the air under the deck would get much warmer than ambient in the cooling season.

Good point. I did not know what the air under the deck would do. I will just go out in front of the deck. Thanks
