Air Conditioning??? Boler?

[dapple]

Hello World.
Well....I bought a boler around 6 years ago.
I used it as is for a couple of years, and for the past two it's been sitting....and I've been so busy with work.

Now that I want to take it out again, and start using it, I want to make some improvements.

Questions:
Does anyone know of a place near Toronto that can help me do some repairs and upgrades?

Can I mount a roof air conditioner onto a 74 boler? Is the roof strong enough to hold it? Is the opening hatch 14x14? I have it parked at another site, or I'd just go out and check it.

Thanks so much!
