Best A/C for a bus?

[Chiller]

I did a general search but only found one or two different types of A/C and heating units. Does anyone have a suggestion of a good A/C unit, with or without a heater, that covers a span up to 500sqft?

I just did maintenance on my Mach 15

- AC is running at 49° now... [emoji15]

It stopped working this weekend - I went up it was so hot I couldn't touch it - it was clogged up with bugs and dust

Sprayed it all out cleaned my blower motor with soap and water and now it's ice box cold again

I just looked online at that system. What gen are you using and is that a quiet system as roof tops units go? I have a Honda 3000i gen that will be under the bus.

I don't know the Generation but it's 3yrs old - that Generator will do fine though
It's very quiet inside and out
It does pull a lot of amps (1 if I was to do it over I'd go with the 12.5 or 13 I forget which it is but it only pulls 9amps
