Recently had new unit installed and lines ran. The air coming out of the ducts is cold but house still isn't cooling off temp set at 71 with temps as high as 88. Some ducts do not blow hard at all and someone covered one up when they laid a new floor in master bath before we moved in. What could be wrong?

If it was just installed there is a warranty... call the people that did the work back and make them fix it..

Agreed, crappy ductwork, leaking ducts off the boots, flex doing loop - d - loops all over

Blower motor tapped too slow

Could be a 100 things or combination thereof
