Rooftop AC’s

[JTW]

ok.. so any suggestions on what brand of drop in rooftop ac? I don’t need anything too fancy.. just cold and dependable. Thinking 15k btu as the trailer isn’t insulated... at least yet. Trying to figure out a good way to go about that too as the interior is finished. 24x8.5x7’

Dang! Pull cabinets remove wall & celling finish and have it foamed, reinstall said components

I had my shop insulated with foam and it knocked 40 degrees out of the ceiling in the summer.

My shop is an authorized Carrier dealer, I was impressed with there equipment as an HVAC tech before I worked for a shop that carried them. I’ve seen and worked on a few of there RV roof mounted units and there of good quality imo. Domestic and Coleman make decent units as well. They all typically use 2 different brand compressors and both are good. For your set up, your looking for a unit that has the controls (thermostat) on the system itself, that would be easier to deal with. The ladder you would have to run stat wire and a thermostat on the wall. All of the RV roof mounted units use 110v so you can plug that directly into a dedicated portable generator to run it.

Oh and to note about an external thermostat control. Those aren’t your typical thermostats. They wire different so you’ll need to but there’s and that means more money just FYI

I saw this setup here in MI just last week. Have you considered a patchwork thru 2x4 stud diamond plate horizontal fresh air exhaust HVAC system?

I thought CP talked you out of installing an AC unit

Better check how far that will come down from the ceiling -I believe you will loose a little height where you place it.. @Cuoutdoors

The problem with pulling the interior is it’s aluminum and taped at the seams.. the chances of me removing everything without f***ing up and creasing a panel isn’t good. I’m afraid that if I use the expanding foam without removing the interior it will blow the panels out. What I need is a type of blown in insulation. Something that’s similar to the beads in a styrofoam block. Something that can be blown in and fill the voids but doesn’t expand and is water proof... Incase there’s a leak or more likely condensation.

Lol.. I’ve been looking for new ones on there. But I’m about at the point of saying f*** it and just buying a new one

The vent is in front of the first machine above the hood... so shouldn’t ever be an issue.

Not really. They only use 2 manufactures compressors, that’s the main driving power for the cooling. The controls are the same concept just different parts. In quality and most on the market I’d say carrier, Dometic and Coleman you can’t go wrong.

defiantly buy new. Used ones are basically junk or were at one time. These units are basically window shaker/throw away units when the compressor goes bad or a leak in the evaporator and not worth fixing at that point. Anyone that has f***ed with fixing a leek on one is sure to leek bad later

Sweet... and how about the heat strips... yay or nay?

Nay if you want to stay warm? They pump out luke warm at best. If it’s in the mid upper 40’s outside and u have good insulation then your good

The element is small so u can still have adequate air flow for ac

Yeah.. we’re in heat pump country here. So kinda use to luke warm air. We had a heat strip on the horse trailer and it was ok at best from what I can remember. Used the little electric heater mostly. Just thinking about those cool evenings where it’s not really cold... but a little heat might be nice.

In that case the heat is between the sheets.
