Run New Ac Line To Attic

On a single story home or the the upper floor of a multiple story home this means accessing your attic to run wire.

Run new ac line to attic.

The coolant line comes into the basement and then runs to the attic through the first and second floor walls. One of my biggest weaknesses. So my options are to put the condenser on a flat roof and run line through side of house or leave condenser on ground run line set through basement and up chimney flue that is doing nothing and out though chimney in attic. The house i recently purchased had a retrofitted additional ac unit installed in one attic.

It started at my first christmas. The amount of surface area of the line sets exposed to the attic are tiny and heat gain loss is quite small. The compressor unit is outside at the other end of the house and the refrigerant supply return lines wander about 50 through a second attic into the cooling unit. It is a r 22 system.

Have explored multiple places to run line set and original contractor hosed me by running it up the wall between windows. New board arrived and that solved the problem. Line sets need to be insulated primarily to avoid accumulating condensation frost creating localized moisture problems the thermal losses are a secondary issue with only a tiny effect on system efficiency. If your indoor unit is in your crawlspace this might be you.

New lighting cable computer networking and sound systems can all require wiring that may need to come through the ceiling. Short run line sets at ground level fit the bill here. Just open the box and figure it out. But to answer the question is there a minimum length for a mini split s line set.

The line goes from. I have a 34 year old trane air conditioner that needs to be replaced. The contractors i had come in want to cut the line in the basement and attic flush it with a cleaner and then re use.
