AC unit on a deck?
Tom Fuhs
The existing AC unit is right at the corner of where the deck will go. But
the only other place where it could go is right next to the dryer vent. No
way to move the dryer vent with out making it a 30+ foot run with lots of
elbows. The HVAC guy I called came out, saw the dryer vent, and said nope!
As my existing heat/AC is over 20 years old, I asked him to give me a price
on replacing the equipment with new high efficiency equipment. He said that
the newer AC units were very quite and I could probably put the new unit on
the deck where the existing is now. I sure that the old unit would vibrate
the deck a lot and make it act as a sounding board. Are the newer units
THAT much quieter? He installs Trane equipment if that makes any
difference. Also, as the new furnace would vent and draw combustion air
through those PVC pipes at ground level, I'm not sure where to have those
exit the foundation. The best place for them from a short/direct run
standpoint would bring them up through my deck around where the the AC unit
is now. How close to the AC unit could they be? Another option would be
over where the dryer vent is. How close could they be to that. These vents
are for gas fired forced air heater combustion air in and exhaust gas out
and also for a power vented exhaust for a gas fired hot water heater. I'm
trying to consider all my options. Thanks for any help.

They ALL still vibrate...

So would a new one

Quieter yes...still vibrate.

Not really.

Check your local codes for that...your installer should be able to get or
show you the code.

You DO NOT want the intake for the furnace over or near the dryer
vent..think lint...

You've confirmed what I suspected. I think I'm going to see about locating
the AC unit out past the edge of the new deck, on the ground where it
belongs. This will put it about 14' away from the house. Thanks again.

AC unit to that with rubber bushings. Or cut
post-holes through the deck, run posts up through
them, and mount the AC on it's own platform.

cut the deck so that it had room to set around the slab, and set the unit on
that...provided they still took into consideration service later...and set
the unit out far enough.
In other words...for lack of a better term...cut a hole in the deck, and
have the unit setting on a slab that would be level with the deck.

Well, the original idea was that, if you mount the unit to
something heavy, with rubber mounts, then it will still vibrate,
but the slab won't (much), and thus the deck won't turn into a
sounding board. I suspect that this works best if the ratio
of mass btw the slab and vibration source is an irrational number,
(and very large) but I'd have to ask some ex-sub person from
groton, to be sure. (I wonder if they're allowed to tell me?)

Problem with that is, slabs today are not concrete..
They are foam, sprayed with a crete mixture....weigh about 10lbs for a 48X36
incher..

One thing I haven't seen mentioned is the heat from the condenser
unit. And there is a bunch of it. Even a gentle breeze will carry the
heat quite a distance. Do you really want 120+ degree air wafting over
you deck?

Thats because todays units, have blades that will send it about 30 feet or
higher....found that out after installing one and then installing a couple
more on the sencond story of a commercial app....dead air, except where the
unit was installed below.

I've looked at the replies, but I don't see anything about deck maintenance. In
20 years what shape is the deck going to be in? If you put it on the deck you
will probably wind up having to move it to repair the deck under it. On a
separate concrete slab would be a much better choice.

Might be able to give you some ideas as we just went through a similar
situation. Added a room and decks to the house; old A/C was deemed
undersized for the addition.

Originally our furnace venting (the PVC pipes) exited the house near
the dryer vent -- about 8-10' apart. The furnace vents here
apparantly could have been left under the deck _except_ there is a
roof over that part of the deck and it would be against city code.
(The dryer vent is still in the same place, now under the deck.)

The new A/C unit is quieter than the old but I would have it off the
deck if at all possible. It does vibrate and am quite sure if it was
on the deck the sound would be amplified. Here the new unit is on a
roughly 3x3' cement square (like a prefab sidewalk slab).
