How to Replace RV Air Conditioning Units
RV air conditioners run on the same principles as a home window air conditioning unit and usually are between 13,500 and 15,000 BTUs. The main difference is that the window unit is self-contained and the RV unit has the condenser and compressor mounted on the roof. Generally, the air-cooling unit is mounted inside the roof. If yours breaks down, you can replace it yourself instead of paying someone else.
