Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes
Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors. - Negotiate Smartly
Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Flow Rate (GPM) And Real-World Use
- GPM Ratings: Flow rates determine how many water fixtures can run simultaneously. 2–3 GPM supports a single shower; 3.5–4 GPM supports multiple points or higher flow showers.
- Water Pressure: Many RV systems have limited water pressure. Models with low-pressure activation or good low-start characteristics are useful when city hookups or pumps provide weak pressure.
Heat Output Versus Efficiency
- 65,000 BTU: All items here list 65,000 BTU, but actual performance depends on heat exchanger design and combustion efficiency.
- Heat Exchanger Materials: Copper or oxygen-free copper heat exchangers often increase transfer efficiency and durability.
- Combustion Control: Segmented or staged combustion can prevent overheating and improve efficiency across seasons.
Installation And Physical Fit
- Door Size Compatibility: Confirm the exterior access door size and whether door kits are available for retrofit installations.
- Indoor vs Outdoor Mounting: Some units are designed for indoor installation with proper venting; others mount externally on the RV wall.
- Integrated vs External Components: Models with integrated relief valves or included shower kits reduce accessory purchases and simplify installs.
Altitude, Climate, And Freeze Protection
- High-Altitude Operation: Look for units rated for high-altitude use if you camp at elevation; combustion and air/fuel ratios can be affected at altitude.
- Freeze Protection: Automatic freeze protection or built-in measures are key for cold-weather travel to prevent pipe and exchanger damage.
Safety And Code Compliance
- Pressure Relief Valve: Built-in relief valves meeting ANSI/CSA standards reduce extra hardware and potential leak points.
- Certifications: CSA, ANSI, or other recognized certifications indicate that a model meets regulated safety benchmarks. Verify requirements for your region.
Controls, Monitoring, And Comfort
- Thermostatic Control: Precise temperature control (±1°F claims) improves shower comfort and reduces temperature swings.
- Remote Monitoring: Remote controllers that display gas usage, voltage, and GPM can help manage fuel and electrical resources on long trips.
Durability, Materials, And Maintenance
- Heat Exchanger Longevity: Copper or oxygen-free copper exchangers often require less maintenance and resist corrosion.
- Fan Types: Brushless DC fans can increase service life and reduce electrical draw.
- Service Access: Check how easy it is to access components for cleaning, anode checks (if present), or repairs.
Comparison Perspectives
- RV Full-Timers: Prioritize freeze protection, high-altitude performance, integrated safety components, and monitoring features to manage resources.
- Weekend Campers: Consider plug-and-play kits that include shower accessories and dual outlets for outdoor convenience.
- Small Space Installations: Choose compact indoor-rated units with stable temperature control and lower max GPM if only one fixture is needed.
Practical Tips Before Purchase
- Measure your existing opening and verify door kit availability or replacement door sizes for retrofit.
- Confirm gas supply capacity and regulator compatibility for 65,000 BTU operation.
- Check local codes for venting and indoor installation requirements when mounting inside the RV or cabin.
- Allocate time for professional installation if you are not experienced with gas and venting systems.
