What Are the 2026 Furnace Regulations?
Starting in 2026, new federal and state regulations require furnaces sold in certain regions to meet Ultra-Low NOx (nitrogen oxide) emission standards. These regulations are part of a broader push to reduce air pollution and improve air quality across the United States.
For Colorado homeowners, this means the furnaces available for installation are changing. The new standards require furnaces to produce significantly fewer nitrogen oxide emissions than current models.
How This Affects Furnace Replacement Costs
Ultra-Low NOx compliant furnaces use more advanced combustion technology, which typically means a higher upfront cost compared to standard furnaces. However, there are important offsets:
- Federal tax credits — High-efficiency furnaces (95%+ AFUE) may qualify for federal energy tax credits up to $600
- Utility rebates — Xcel Energy and other Colorado utilities offer rebates for high-efficiency furnace installations
- Lower operating costs — Higher efficiency means lower monthly gas bills, often saving $200-400 per year
- Financing options — On Time Heat & Air offers 0% APR financing to spread the cost over time
