Furnace and heat pump installation with zoning control

[refmet]

That was an easy job for once! we had a lot of room to work and even though the house is not a new construction the part we were working on was brand new. We installed a new model of zoning panel (White Rodgers- comfort zone) and it works well but don't use it in add-on apllications where the coil is located after the heat exchanger because the maximum adjustment time for the first stage (heat pump)is 25 minutes and then the panel turns on the aux heat wich makes no sense when we all know that units working with R410A have a slower response time to deliver their full capacity than the one using R22. We installed a 4 T unit and a 3,5 T and there was already a 3 Ton Lennox unit for the 2nd floor, everything works just fine, HO is pleased...

now i dont know much when it comes to zoning other then what we touched on in school years back but it was on larger scale .. so if im wrong someone please correct me .. anyway .. i am guessing that pipe off supply into return is bipass ... how are you not going to have freeze up issues with the evap ? all ldoes look nice

You answered your own question there :D The bypass allows excess supply pressure to reroute into the return duct when one zone is closed.

Why did you use White Rodgers zoning when you are a Carrier dealer (or Bryant)??

What type of water heaters are to the left of your air handler? Also, why did you install Bryant condensing units with a carrier furnace, why not install one brand or the other.

Their distributer probably carries both Carrier and Bryant and the fan coil model #'s are the same but they did not change the little plastic logo from Carrier's blue oval to Bryant's red badge.

Our local branch does the same to us, we'll get a Bryant fau and a/c and the coil will usually have a carrier badge and we just remove it so the customer does not know or ask why.

Very nice, really like how you put the trap in the floor drain, never seen that before. ;)

What your doing with those gas flexes looks like it against the B149 gas code, "not pass through a wall, floor, ceiling, or partition".

2x60 gal. electric 4500W Standard cascade HW Tanks and the guy from south California answered your other question.:confused:

You are absolutely right and the inspector already put a tag on his report, so I have to fix it Friday, I hate to hook the gas line to a stove!:mad:

I hope you sealed up that adjustable elbow where the crimped end is cobbled into the duct. Looks like it'll leak. They do make short tab collars for that.....especially for an exposed application.

I forgot about the distribution part. WeatherTech (the Carrier and Payne distributor here) dropped Bryant a couple of summers ago. Bryant accused them of selling too many carriers and not enough Bryant. Oh well.

looks great, the only thing i would have done different is have the humidifier above the filter

Magic marker marks on the sheet metal, if its a out source better let em know its photographed. Besides all the other whats wrong posts, if half of the install crews ever tried to even attempt doing as clean of a job, we could all hope to be as attentive.

Thanks, and btw we sealed that collar...
