Run New Ac Line To Attic

New board arrived and that solved the problem.

Run new ac line to attic.

So sometimes you have to get a new line set numbers 1 2 and 3 above. The line set is easily accessible and wouldn t be too costly to replace. 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. But to answer the question is there a minimum length for a mini split s line set.

Just open the box and figure it out. New lighting cable computer networking and sound systems can all require wiring that may need to come through the ceiling. It is a r 22 system. One of my biggest weaknesses.

The house i recently purchased had a retrofitted additional ac unit installed in one attic. I have a 34 year old trane air conditioner that needs to be replaced. The prior owner just had a new ac system installed in which they switched from the equipment and metal ducts in the crawlspace to flex ductwork equipment in the attic where temps have regularly been in the 130 150 degrees this summer. On a single story home or the the upper floor of a multiple story home this means accessing your attic to run wire.

It started at my first christmas. If your indoor unit is in your crawlspace this might be you. The amount of surface area of the line sets exposed to the attic are tiny and heat gain loss is quite small. Short run line sets at ground level fit the bill here.

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 coolant line comes into the basement and then runs to the attic through the first and second floor walls. 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.
