FAQ

How Do I Choose The Right BTU For My RV?

Start by matching cooling capacity to your rig size and layout rather than chasing the biggest number. A 13,500–15,000 BTU rooftop unit covers most mid‑size travel trailers and motorhomes, while very small campers can be fine with lower-capacity units and larger, well‑insulated coaches may benefit from higher airflow or a ducted solution.

Consider sun exposure, insulation, how many people will be inside and whether you need a heat pump or dehumidifier. Also factor in the electrical side: check your coach’s circuit capacity and your generator or inverter capability so the unit can run without tripping breakers.

Can I Install A Rooftop Unit Myself?

You can if you’re comfortable working on the roof and you have a helper, the right tools and basic wiring experience. Confirm the vent opening dimensions first and whether the unit is an upper rooftop component only, since many models require a separately purchased lower control panel or distribution box. Inspect the unit on delivery for damaged shrouds or missing hardware, follow the manufacturer’s wiring instructions and secure the gasket and hold‑down bolts tightly.

If you’re unsure about electrical connections or roof sealing, plan for a professional install to avoid leaks or wiring problems.

How Can I Reduce Noise And Power Draw?

Choose a unit with a higher SEER rating or an inverter compressor if you want smoother starts and lower runtime, and use lower fan speeds at night to cut perceived noise. Proper mounting and a good watertight gasket reduce vibration noises, and routine maintenance such as cleaning or replacing filters keeps airflow efficient so the compressor doesn’t overwork. Match the unit to a generator or inverter that can handle the startup load—many owners successfully run 13.5K–15K units from a 3,500 W generator—and consider additional insulation or reflective roof covers to lower cooling demand.

Customer Preferences

When choosing between the Advent 13.5K, Brisk II and RecPro 15K you’ll find customers typically prioritize fit and installation ease, real-world reliability and noise, and the unit’s power versus efficiency trade-offs. If you need a straightforward plug-and-play replacement you’ll lean toward the Advent or Brisk II for standard vent fit and simple installs, whereas you’ll favor the RecPro when quiet operation, inverter smoothing and better dehumidification matter most.

Wrapping Up

When you choose an RV air conditioner, prioritize the combination of BTU capacity, energy draw and noise level that fits your rig and generator. If you need a straightforward, budget-friendly replacement that installs easily, choose a proven value unit.

If quiet, inverter-driven performance or ducted-system compatibility matters more, prioritize premium models that reduce runtime and feel more comfortable in small spaces. Match the unit to your electrical limits and plan for safe roof handling during installation to avoid damage and ensure years of reliable cooling.
