I recently asked for 4 bids for HVAC on a new house. Only one contractor actually did a Manual J. One said he did but when I asked to see his work he claimed he had deleted from his computer ( I really dont think he did one ). The other two didnt do Manual J calculations. We wound up going with the contractor that did the Manual J calculations. I have spoken with friends of mine who have received quotes for replacement systems without any indication of what equipment they were bidding.

I apologize because I forgot to add this on to my last question, but I've noticed all over the forum that it's almost a universal recommendation from you pro's to make sure my contractor does a load calculation and measures the duct work in my house to ensure they're selling me on the correct sized system.
I've had 4 of the more reputable companies out for bids and not one of them has done this.
Is it something I should have to ask them to do, or am I calling the wrong companies?
I have a basic 35 year old ranch in the midwest, and these guys typically just look at my old equipment to make their decisions on deciding what to offer me.
Can it be they've done it so long it's second nature and easy for them to tell?
This is the last heat and AC I hope to buy so I don't want to kick myself for the next 15 years because I made a mistake.
Thanks for any advice.
