Spray foam insulation air register boot

I'm looking to insulate about 10 air register boots underneath my house. The metal is currently exposed leading to some condensation. I'd like to foam them as that seems best bet for insulation in the tight spaces behind the boots.

Problem I've come across is the box store canned spray products I've tried won't spray upward/overhead and/or can't spray 12-18 inches into a tight space.

Anyone have experience with a diy foam that allows overhead spray and has enough pressure to spray from distance of 12-18 inches?

Or, do you know if an company in Greenville area that would do a job this small? I've spoken with 2 that had $/foam use minimums that far exceeds what I'd need?

OT: HVAC question

@idohvac2 and any others

6th month old 5 ton Trane system just had my first semi-annual service today.

Tonight my condensation pump is not pumping. It shows the power and alarm lights.

I’m waiting on a call back, but wondered if there is anything that might have been tripped or that I could check.

Short term I have a catch basin under it draining into a 5 gallon bucket.

Thank goodness for water sensors I have placed strategically!

Democrats really don’t like it when you make fun of their shitty policies. This is why they want to limit your speech.

They only want government sponsored lies. If Hillary and Rachel Maddow lie, for example, that is OK.
