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.
Heating Capacity And Coverage
- BTU Output: Choose a unit whose BTU range aligns with your area’s cubic volume. Higher BTUs suit larger, poorly insulated spaces; lower BTUs are better for insulated garages or small workshops.
- Coverage Estimates: Manufacturers provide square-foot guidance—use these as starting points and adjust for insulation, ceiling height, and air leaks.
Fuel Compatibility And Runtime
- Tank Size: Check whether the heater uses 20 lb, 40 lb, or larger tanks and confirm run times. Longer runtime reduces refueling frequency.
- Hose And Connections: Look For Included LP hoses, regulator compatibility, and hose length if remote mounting is needed.
Safety And Certifications
- Certifications: Prefer CSA or other recognized certifications which indicate tested safety and performance.
- Safety Features: Standing pilot, piezo igniters, ODS (oxygen depletion sensor) where applicable, and tip-over protections for certain units matter depending on installation.
Installation And Ventilation
- Indoor Use: Many convection heaters Are Suitable For Indoor Use Only With Proper Ventilation. Confirm manufacturer guidance for indoor vs. outdoor operation.
- Ventilation Requirements: Heaters producing combustion byproducts need adequate airflow or venting; sealed or vent-free units have different requirements.
- Mounting & Portability: Consider stationary mount models for permanent shops vs. portable units for temporary job sites.
Operation And Controls
- Ignition Type: Piezo, standing pilot, or electronic ignition affects reliability and ease-of-start. Piezo and standing pilot often require no electricity.
- Adjustability: Variable BTU settings or adjustable outputs let you tailor heat output to changing conditions.
Durability And Intended Use
- Commercial vs. Residential: Heavy-duty, high-BTU units Are Designed For Construction And Industrial Use; match the product class to your environment.
- Materials & Build: Look for corrosion-resistant finishes and robust components if used in dusty, damp, or high-traffic areas.
Comparative Perspectives
- Large Spaces: Models With 150–200k BTU Ratings (Dyna-Glo, Mr. Heater MH200C) Provide Rapid Heating For Very Large Or Poorly Insulated Spaces But Require Robust Fuel Supply And Ventilation.
- Medium Workshops: 50k–80k BTU Units (ProTemp, Dura Heat, Mr. Heater 30–80K) Balance Runtime And Coverage For Typical Garages, Barns, And Shops.
- Run Time vs. Portability: Units Designed For Large Cylinders Offer Longer Continuous Run Times; models Using 20 lb Tanks Are Easier To Move But Need More Frequent Refueling.
- Safety Tradeoffs: Continuous pilot systems provide instant heat but may consume fuel; piezo ignitions avoid constant pilot consumption but need reliable ignition operation.
Installation Checklist
- Verify local codes and permit requirements for indoor propane heater use.
- Confirm ventilation and clearance specifications in the product manual.
- Use certified gas fittings and leak-test connections after installation.
- Place carbon monoxide or oxygen depletion detectors where required.
Maintenance And Troubleshooting
- Regularly inspect fuel lines, hoses, and connectors for wear or damage.
- Clean combustion ports, vents, and exterior housing to maintain airflow.
- Follow manufacturer guidance for winterization and storage.
