Roof Mounted Heater/AC Units Recommendation (do they exist?) for '67 Overlander

[Billyjchase]

Greetings!

Our original roof mounted AC unit for our '67 Overlander finally broke down and I'm curious to know if any company makes a AC + Heater (all in one) roof mounted unit that we can replace the now deceased AC unit with?

If so, any recommendations and or point me to previous posts on the topic and installation tips would be greatly appreciated.

Thanks in advance!

Some things to consider during the search:

A/C units come in several capacities as rated in British Thermal Units (BTU) which is a measure of cooling or heating capacity. More BTUs, more cooling or heating.

They also come in straight air conditioning versions, which are simpler mechanically.

A "Heat Pump" version reverses the air conditioning action to provide some heat by sucking heat from outside, and providing it to the interior. They tend to quit working effectively when it gets too cold outside--around 40 degrees Fahrenheit.

A "Heat Strip" is a feature that provides an electrical resistance heater in the same system that, instead of running the compressor, provides some heat from hot wire elements in the return air duct. Our 22 footer has a heat strip that works to take the chill off the interior, but it's frankly not that powerful. We use the propane furnace if it gets too cold outside.

There MAY be a unit that does both "Heat Pump" and "Heat Strip" out there, but I'm not aware of one.

There are also "low profile" units that hug the roof and do not stick up as much.

For other examples and more details, search the forums by using the blue search box near the top of the page that has the 'AIRforums' radio button in it. That one works best. try "Air Conditioner replacement" as a search string...
