Frequently Asked Questions
What size RV furnace do I need?
The size of your RV furnace depends on your rig's square footage and insulation. Small campers typically require 12,000 to 20,000 BTU units, while larger travel trailers or motorhomes may need 30,000 to 40,000 BTU furnaces.
Are Suburban and Dometic furnaces interchangeable?
Not always. While both brands offer similar BTU ranges and ducting configurations, installation specs vary. Always check measurements, wiring, and vent compatibility before replacing one with the other.
How do I know if my camper furnace is LP or natural gas?
Most RV furnaces run on LP (liquid propane) gas. Check the label on your unit or owner’s manual to verify. Some Dometic models offer dual fuel options, but LP is standard for RVs.
Can I install a new RV furnace myself?
If you're experienced with RV electrical and propane systems, DIY installation may be possible. However, for safety and warranty reasons, we recommend professional installation.
What are common signs I need to replace my RV furnace?
Frequent cycling, weak airflow, inconsistent heat, strange odors, or ignition failure can all indicate it’s time for a replacement. Older models may also lack efficiency and safety features found in newer units.
Do you carry ducted and non-ducted RV furnaces?
Yes, we stock both. Ducted furnaces distribute heat throughout multiple zones in your RV, while non-ducted units heat a single area directly—ideal for small campers and travel trailers.
What is a good replacement for the Suburban SF-30F furnace?
The Suburban SF-30F can typically be replaced with the same model or another SF-Q or SF-FQ series furnace in the same BTU range. Always confirm compatibility before purchasing.
Are small propane furnaces safe for campers?
Yes, when properly installed and ventilated, small RV propane furnaces are safe and designed specifically for compact living spaces like campers and trailers.
