DIY Replacement Versus Professional Installation

Choosing between DIY and professional replacement substantially affects RV furnace replacement cost and safety outcomes.

When DIY Is Reasonable

DIY replacement may be suitable for mechanically inclined owners replacing like-for-like units with minimal venting or wiring changes. Savings in labor costs can be significant, but the installer must have proper tools and knowledge of propane and combustion safety.

When Professional Installation Is Recommended

Professional installation is strongly recommended when venting modifications, gas line work, complex wiring, or warranty compliance are involved. Certified installers understand combustion clearances, exhaust placement, and leak testing procedures that protect occupants and property.

How To Choose The Right Replacement Furnace

Selecting the right furnace involves evaluating heating capacity, fuel type, efficiency, physical dimensions, and compatibility with existing vents and controls.

• Match BTU To Space: Choose a unit sized for the RV’s square footage and insulation level to avoid under- or overheating.
• Check Physical Fit: Measure the existing cavity and mount type; confirm the new unit matches mounting brackets or plan for adaptors.
• Consider Fuel Availability: Propane remains the dominant option for off-grid use; electric options suit shore-powered situations.
• Assess Efficiency Vs Cost: Higher-efficiency units save propane long-term but have higher upfront cost.
• Warranty And Support: Favor manufacturers with strong RV-specific support and parts availability.

Typical Installation Steps And Timeframe

Installation time and steps vary by complexity, but the following summarizes a typical professional replacement to estimate labor time and cost.

1. Remove old furnace and inspect cavity and venting.
2. Prepare and repair the mounting flange, ductwork, and any corroded components.
3. Install new furnace, attach venting and exhaust, and connect gas line with approved fittings.
4. Wire the thermostat and blower controls, test blower and ignition sequences.
5. Perform leak tests on gas connections, check combustion and exhaust, and validate thermostat operation.

Most straightforward replacements take 2 to 6 hours, while complex reroutes or cutting new flues can take significantly longer.

Costs Related To Venting, Ducts, And Thermostats
