It doesn't matter if you're a seasoned traveler or you just bought your first RV, replacing or upgrading an RV climate control system can be overwhelming. Between BTU ratings, refrigerant changes, and thermostats that look identical but are actually completely different, replacements and upgrades are often more complicated than a simple swap.
At RV Products Shop, we have been helping RV owners choose replacement air conditioners, verify compatibility, and understand RV climate control systems for over a decade. We have created this guide to bring together some of the most helpful information and knowledge that we have collected over the years to help you feel confident that you are choosing the right system.

FAQ
Can I just replace the rooftop unit?
Sometimes, but not always. The rooftop unit must be compatible with all other system components. Compatibility can depend on refrigerant type, connector type and wiring, and functions supported by the control box and thermostat.

Do all RV air conditioners fit a 14" x 14" roof opening?
The industry standard is a 14" x 14" roof opening, so almost all rooftop units will be designed with this in mind. However, compatibility also depends on roof thickness and other system components.

Are heat pumps worth it in an RV?
For many people, yes. Heat pumps can help reduce costs by lowering propane usage, and may be sufficient as a standalone heat source in especially mild temperatures.

Why won't my new RV AC work with my old thermostat?
Modern RV HVAC systems have updated communication protocols between components, along with more features and functionality options. There's a good chance that a thermostat designed to work with an older system will not be compatible with newer components, including the rooftop unit.

How do I choose the right BTU size?
RV size is only one factor. Climate, insulation quality, ceiling height, and the number of occupants all affect your cooling needs.

Can I run my RV AC on a generator?
Yes, as long as the generator is capable of handling the startup surge of the rooftop unit along with all other appliances that will be running simultaneously.
