Buyer’s Guide: What to Consider
Choosing the right gas furnace involves more than just picking a brand. You need to consider efficiency, size, installation constraints, and long-term costs. Here are five key factors to guide your decision.
- AFUE Rating: AFUE (Annual Fuel Utilization Efficiency) measures how much gas becomes heat. Higher AFUE (96%) means lower energy bills but often requires PVC venting and more complex installation. Lower AFUE (80%) is cheaper upfront but costs more to run. Choose based on your climate and budget.
- BTU Output: BTU (British Thermal Units) indicates heating capacity. A 60,000 BTU furnace suits small homes, while 100,000 BTU handles large spaces. Oversizing wastes energy and causes short cycling; undersizing leaves you cold. Use a load calculation to match your home's needs.
- Blower Motor Type: Multi-speed ECM motors adjust airflow for better efficiency and quieter operation, reducing energy use. Single-speed motors are simpler and cheaper but less efficient. For optimal comfort and lower utility bills, prioritize ECM motors, especially in variable-speed models.
- Installation Configuration: Furnaces come in upflow, downflow, or horizontal orientations. Upflow units draw air from the bottom and expel from the top, ideal for basements. Downflow suits crawl spaces, and horizontal fits attics. Verify your space's configuration before purchasing to avoid costly returns.
- Warranty and Compliance: Look for 10-year parts warranties, often requiring registration within 60 days. Check local Low NOx regulations, especially in California and Colorado, where some models aren't compliant. Also, consider fuel type—natural gas or propane—and ensure your supply matches the furnace.
Conclusion
Selecting the best gas furnace for your home comes down to balancing efficiency, capacity, and installation needs. High-AFUE models like the Goodman 96% units save on energy bills, while budget-friendly ACiQ 80% options offer dependable heat at a lower upfront cost. Always factor in your home’s size, ductwork, and local regulations.
For most homeowners, a 96% AFUE furnace with a multi-speed ECM motor provides the best long-term value. If you need a complete system, the Oxbox by Trane combo delivers year-round comfort. Whichever you choose, professional installation is key to maximizing performance and warranty coverage.
