High-SEER heat pump outdoor units to fit narrow side yards?

[DanKegel]

My side yards are narrow, and it's a challenge finding a high-efficiency heat pump whose outdoor unit won't bulge out too far from the house.

I'm compiling a table of high-seer models vs. how far each protrudes from the house. Here's what I have so far:

Brand Model SEER depth clearance total source

Carrier Infinity 25VNA 20 35" 6" 41" http://dms.hvacpartners.com/docs/100...25vna-03pd.pdf
Lennox XP25 23 39.5" 6" 45.5" http://tech.lennoxintl.com/C03e7o14l...ShbC/1252b.pdf
Am.Std Platinum 20 20 29.75" ? ? http://www.americanstandardair.com/p...eat-pump-.html


I plan to add Mitsubishi and Fujitsu even though their ducted models aren't quite high-SEER, since they're so thin.
It takes more time than I'd expect to dig up this info.

If anyone else has the info handy and wants to help complete that table, please jump in!

Carrier and york/coleman use to make a horz discharge heat pump. I will see if i or someone else can find the numbers.

Carrier is The 25HHA4 is up to 15 SEER Heat Pump

I found a carrier 38QRR not really any kind of high eff though.

Soon, Mitsubishi is coming out with a conventional air handler to mate with its hyperheat outdoor units that will beat the 3 you mentioned.

[DanKegel]

That's interesting. Where'd you hear about it, and how can I find out more? Does it have a model name yet?

Samsung has one in their DVM Eco line. One of my reps brought a training trailer by the shop the other day outfitted with a 1 ton conventional air handler and a 2 ton medium static air handler on a 3 ton outdoor

[DanKegel]

Thanks for the tip about Samsung DVM Eco. Must be real new; the only pages in the web about it seem very much not oriented towards US residences.
Got a link?

[jtrammel]

I couldn't find a link, you'd have to talk to a Samsung dealer in your area. The conventional air handler is new but it exists and any Samsung distributer should have it or be able to get it.

What are the concerns with locating the condensing units in the Backyard?

[DanKegel]

The house is a city historic landmark, and we get a big tax break in exchange for renovating
the house and garden, and keeping everything true to its original look.
A small condenser the service area of the side yard would probably be ok, as would solar panels if not visible from the ground or the street, but condensers might really stand out in the back yard.

Besides, the side yard is closer to the indoor units, and would require a shorter refrigerant line run.

[DanKegel]

Looks like the side yards are just too narrow for a heat pump to fit and obey code, so long run to backyard it is.

Have you looked into any micro channel brands, I thought those had smaller footprints than typical coil units. Nordyne seems to make some taller units but smaller L X W .Their 16 SEER is 31" L x W and 43.5" tall up to 5 tons.

[Brent Ridley]

I would look into the Carrier 24VNA9 or 25VNA8 - it's a 18/19 seer 5 stage unit with a VERY small footprint. The 2 and 3 ton condensers have a 25" x 25" footprint.

[DanKegel]

Nope, I'm just going through the major brands (carrier, lennox, trane, maybe mitsubishi) one by one and getting estimates.

The local Lennox guy is next, and he does Mitsubishi too, wonder which one he'll recommend.

Water source heatpumps have zero external footprint, are ultra high efficiency, and offer 30%tax break federal and most states offer additional breaks...
