RV air conditioning is usually comprised of 1-3 roof mounted a/c units. Older a/c units merely ‘dump’ air into the living &/or bedroom areas. Newer RVs have ducted air that distributes air throughout the RV.
Most RV a/c units also contain heat pumps that deliver warm air for heating areas of the RV.
Some older a/c units contain heat strips that produce a nominal amount of heat.
Roof a/c units and heat pumps operate on 120 volts, and are something of a power hog. This normally requires that the RV is plugged into shore power.
RVs usually have a furnace for heating using LPG. An RV furnace consumes a significant amount of LPG.
The above heat and a/c systems are controlled by a wall-mounted thermostat with one or more zones.
