How long to install Central heat & air ?
I am having central heat & air installed in my home this week. Originally, I was told it would take 5 days, yesterday I was told it could take up to 2 weeks. I was expecting a crew but, only one man was sent out. The first day he pulled the (2)floor heaters and rough patched the openings. Today he cut the hole in my roof and put in a metal stand.
I was wondering why he would cut the hole so soon, I would think that would be done after all other work was completed. He says he now has to install the gas line and electric, he also said tomorrow he would bring a "helper". The pace of the work so far seems pretty slow.
Also, I'm wondering if the work is being done correctly. The AC stand metal border was pushed under the roof shingles. He says this makes the area water tight, but I wonder if that's enough. I would appreciate if someone would let me know what they think.
I would like to be more knowledgeable in the event I need to contact the supervisor.
