Here is my Idea of 16 tons of cooling and almost 400,000 btu of heating . All heat pumps and 93% furnaces
cplt48 and gms9090 variable speed furnaces. My supplier said you could not twin the furnaces with heat pumps SO I QUADED THEM!![/URL]
ALLRIGHT BOYS TEAR IT APART!! LOL replaced two 200,000 furnaces with standing pilot and no ac units and sold them on 4 heatpumps!

Motors run on smoke!! When the smoke comes out of it, it needs a new one!

They look too close together. Seperate disconnects would be nice too.
Did you know those are Goodman units?

Another angle of the outdoor units
There is more room between them than it looks you can
walk between them
That box on the wall is an outdoor panel with breakers for each unit

solid state relays for each connection from the thermostat
I am amazed each time the furnaces fire it is like a symphony identical timing on the heatpumps and the backups.
The supplier said it would not work but I installed these last OCT. and have never looked back. they have been very reliable.
Had to think a while before posting because I knew I would catch grief, but the only thing I can say is IT WORKS GREAT!! This is in a theatre that is owned by the community and run by voulenteers nice set up!!

Tees on the vent or intake? Either way looks like a recirculate situation. What do you guys think about the ECMs and twinning?

Not going to bash the brand being I like Goodman.
It looks good and I would never have thought of hooking up all 4 together.
Just a little comment ..... I hate when someone uses that orange spray foam insullation, it looks like crap if left that color. As far as the gas piping, they could have cleaned it up a little .... maybe a clamp or two to make it look a little beter then it does.
Im not real big on 20' whips on the condensors lol . Cnduit would look better but I can see it being with the crossing of the piping it would be a little more hassel.
In all it looks great to me. Anyone can judge but then we dont know what the bid was and if you did everthing the most expensive way or the hardest way........... you might not be getting that many bids the way some people lowball now days.
That looks like one large wood return there ?????? Bet that has a lot of bracing for that weight lol

Looks like Bald beat me to it about the T on the exhaust. I totaly agree... problem waiting to happen on a cold crisp Jan night.
Do you have the before pictures for us?
Professional Member*
I have found T's on the exhaust to be invaluable, on cold crisp nights it lets some of the moisture to escape straight up instead of down or condensing on the end of an elbow and freezing. JMO
Wish I would have taken before pictures, where the 4 units set now there was two huge arcoaire 200,000 btu furnaces,

You sure know how to run a profitable business.... Put in Goodmans so they'll call you in 5-6yrs. for replacement!
WHY?
Professional Member
So special ......I see in your web site that you dont even show what brand you sell. You that proud of what you sell or just put in Goodman when thats what they want, and to everyone else ...... you bid whatever brand they want ??????

Hmm, 4 variable speed blowers pulling return air from the same place at the same time...sounds like bad mojo to me.
I have seen an installation with 2 variable speed units pulling from a common return. In 3 years they went through about 8 motor modules between the 2 units because the variable speed blowers were fighting eachother, causing the motors to hunt. Constant ramping up and down will kill ECM motor modules.
The reason the supplier told you that the furnaces could not be twinned probably had a lot more to do with the ECM blowers than with the heat pumps.
