I am new on this forum and need help with a HVAC issue.
I am converting my garage into a workshop and want to run AC into it. Fortunately, my home was a model home so the garage is already finished. The only thing I need to do is reconnect the duct work for that space. The duct work is still in the attic space, it's just been disconnected and tied off.
So, I need to know what components I need to split the current duct. I don't have a clue about the correct terminology, but I hope my explanation is clear enough.
But to your question. You have 12" flex duct. So if you take a 2" piece of 12" single wall pipe and insert it into each end 12" and use the zip tie straps that should take care of reconnecting. Where the two end met on the pipe wrap with duct tape.
Actually I need to connect both pieces of flex into the other flex that you see attached to the wall. The two pieces of disconnected flex you see in the pics are the return and feed duct (if that's what they're called. They disconnected the return and feed lines from the unit before the house went up for sale. I suspect they had some type of T split if that's possible.
That make sense?
Reread my original post and I don't think I did a good job of explaining the situation.
Your garage is 1 hour rated for fire from the rest of the house. That is why when the house was sold the runs had to be disconnected. Code states that you can have no heat runs or returns connected to the house system. Carbon monoxide problems could cause big problems. Also if a fire starts in your garage/shop you want some kind of barrier from the house.
Use a seperate system in the garage.
I'm with plumber, wow what a install. This was a modelhome??????:whistling2:
Actually, if you have garage doors large enough for a car to enter the garage. Its a code violation. To connect those ducts. Weather you use it for parking a car or not.
Dude, didn't you read what the man said about the monoxide issue and the fire break? You can't penetrate the garage wall even for supply
And I guarantee that ac won't carry the load on the garage anyway.
Builder's who use the garage for an office will close down all the dampers to divert air to garage. The garage is never calculated in the sizing of the ac.
And damn! -who did the install Stevey wonder or Ray Charles?
Around here the builders have been using all window units .
Its because a car in the garage can be left running. An fill the garage, and duct system with CO(caron monoxide), and kill the occupants that are still in the house.
A different system.
Can't have any duct communication with the system that conditions the occupied areas of the house.
please pay attention to all who say no to ductwork in the garage... Perfect example is my wifes new remote starter operator was so sensitive just putting her keys in her pocket or purse would start the car & we would find it running , (outside) , but it could have been in our garage too. We had it de tuned somehow , please play safe!!!!!!!! our inspector for our new attached garage made the drywall guy come back and box in the roller shaft so the garage was gas tight as possible..
