replacing main AC Duct
So, how involved is replacing the main ductwork on a heatpump..... I am going to attatch a partial picture of what it looks like around the ducting under the house. The runoffs have been replaced, but I need to replace the register boots, and the main ductwork... My heatpump is new, installed in 2008 and it cant cool my small house down to 70 degrees during the day.... (the house is approx 1100 square feet). I have called several local hvac companies and it seems that either they are reallly super lazy or business is really really good and they dont need mine because I cant even get someone to come over and look at the ductwork to tell me what it would cost to replace it..... I am by no means an HVAC person, but I can take something apart and put it back together as well as the next person with direction and instructions..... I have searched some on the internet but am not really finding anything and I am sure that it is verbage that I am using...... I installed a new thermostat and also bought a thermostat with humidity % on it to compare temps and they are within 1 degree of each other at all times.... so, I am just really frustrated by the lack of people in my area willing to work .... and it just amazes me at the lack of customer service......
and yes I know I asked this question last year, but never fully got an answer.... so, I am asking again!
FYI... ductwork is supposively original to the house (1979) so its not that old, but it looks like it is in awful shape and when you look into the return air vents it looks like it is hap hazardly put together....... when I had the runoffs replaced the guy did retape some spots but I just feel like there are leaks, sometimes after it has rained it smells musty in the house.....
so, back to the question at hand..... how involved would it be and is it in any way shape or form a DIY project? and what is the proper ' verbage'
