Yeah in case it wasn’t clear - I wasn’t asking a million vendors to price the job, I was asking them to do a manual J so they could price the job. It took 12 to get 4 to do the manual J. The other 8 came on-site and then refused to do the calcs even though I told them before coming out that it was a prerequisite for me to consider their quote.

I got a variety of explanations for why they weren’t going to do it, most of them along the lines of ‘I’ve been doing this forever - I know what I’m doing,’ but a few disappointingly ‘I don’t know what a manual J is.’ Again, this was AFTER my telling them over the phone that I wouldn’t consider a quote that wasn’t based on the calcs.

Yep, the cost is in the trip is a big factor but sounds like it was their choice to try to sell you. You did the right thing by asking them do the calcs before they came out. Millions of questions are time consuming and costly but better than someone rushing into and pausing mid project with in-decision.

We (I'm cofounder of Electric Air, HVAC contract) have had people pause on day one of install, and that ends up costing the company $10-20K due to delays. Mostly because there isn't something for the team to do for that day or two while we scramble to line up the next customer.

I've had a similarly frustrating experience trying to get contractors to redo my gutters.

They seem fine with the gutter part, but once I explain my rain collection system and my requirements around specific downspout sizing and simultaneous overflow, they just seem to have no interest in doing the bit of work required to make it all fit together.
