Insulate air handler in unconditional crawlspace

[dirtrider88]

So I have alot of condensation on the air handler in my crawlspace. HVAC tech recommended insulating it and that they could do it to the tune of $4-600. I've already insulated the ducts myself using the silver bubble wrap, so figured this shouldn't be too bad to do myself. However the more I look at it the more in not sure how to approach it.
Reason being would be access to the electrical panels and such. If I use that bubble wrap, maybe just have where a flap of it can be removed for easy access for service? Or maybe I'm way off base here and it is a no no to cover up the access panels.

pretty much the nature of the beast, unless you condition the entire crawl space. And if you insulate the box, you will trap that moisture somewhere (hint:against the metal box) and it will rust.

In the homes I have had with this arrangement, I just make sure the water that drips does not accumulate or collect on the joists. Certainly not worth what they want to condition the entire crawl space or even the unit by itself.

Encapsulate and condition the crawlspace is often the best bet. But who knows what to recommend not knowing your locale.

Get a moisture meter and check moisture contents of the floor joists. If it's high I would block off foundation vents and put a dehumidifier in the crawlspace. Warm humid outside air will condense in a cool crawlspace.
