Central Air Units - How Loud?
My wife and I are considering putting our central A/C handler in the garden (under our deck) as opposed to on the roof – saves a few thousand dollars. Does anyone have any thoughts on noise, good brands, accoustic jackets effectiveness, etc.? Thank you so much! Oh, and I think we need a 5-ton unit.

Goodman is considered “contractor’s grade” There are much better units out there at much higher efficiency.
Sometimes the roof is a better outdoor space / garden than the back yard. Stupid???
it is a stupid idea to put it in the back yard…you will be throwing away your garden for a few grand in short term savings..btw it is hard for me to believe that any brownstone needs more than 4 tons
FOURTEEN f79ing TONS? People obviously have much more money than sense; that’s the worst overkill I’ve ever heard. Here’s a n obvious rule of thumb: add up the btu of your window units when you want to install cac, use that as a guide. I get 4×8000+10000=3-1/2 tons for my triplex. And I don’t even use it all.
OP: Consider your neighbors as well if you have a noisy unit in the yard. You can probably build walls around it with an open top and plenty of side ventilation to cut some noise.
Depending on how many floors you have, you might want to put one unit in the garden & one on the roof. I do that & can usually just use the upper one to cool the whole house except when I have a lot of people or we have a stretch of really hot, humid weather.
You wouldn’t mean the air handler, you’d mean the condenser. That’s what you are showing in the photo, and that’s the unit that stays outside.
What ER says, be careful putting under the deck, they need to breathe. Find the unit you want, look up installation instructions on line. They will show the needed clearances.
Honestly tho, by the time you start screwing around with clearances, worrying about the noise, and figuring out how many precious sft you lost from your garden, you may just want to put them on the roof.
Yeah… the exhausting of hot air is more of an issue for placement of the condenser than noise. The new units are pretty damn quiet. And there are units (usually a bit more pricey) that make almost no noise.
Do you mean handler or condenser or a package unit? FIRST absolutely have someone competent do a residential load calculation using manual J. Do not let them base it on square feet or some other rule of thumb. Most contractors over size “just to be safe” but this can lead to short cycling that does not allow for dehumidification and you get a cold humid environment that is not comfortable. At his contractors’ recommendation my neighbor just installed 14 tons of A/C in a four story 25×40 house. He probably needs half that.
Quality new units make very little noise, defiantly nothing that can’t be cured with an enclosure. Just remember these units need a lot room to breathe and they discharge hot air out of the top.
The Goodman that you show doesn’t have a good reputation but I have no personal experience with them.
