Ultra Low-NOx Requires Lower Emission Furnaces
Colorado homeowners, especially those in Colorado Springs and Boulder, may be hearing more about new Ultra Low-NOx furnace regulations taking effect January 1, 2026.
This Colorado law requires lower‑emission (Ultra Low‑NOx) furnaces for any new equipment manufactured after that date. While it does not require homeowners to replace working systems, it can impact future replacement options, pricing, and availability.
If your furnace is aging or struggling to keep up during Colorado winters, understanding these changes now can help you plan wisely and avoid rushed decisions later.
Thinking about furnace replacement, you’ve got options.
What Is Ultra Low-NOx and Why Does It Matter?
Nitrogen oxides (NOx) are pollutants that contribute to smog and reduced air quality along the Front Range. Reducing NOx emissions helps improve public health, particularly for residents with asthma or respiratory sensitivities.
Does This Law Mean You Have to Replace Your Furnace?
No. Existing furnaces can continue operating in Colorado Springs and Boulder homes. The law only applies to new equipment manufactured after January 1, 2026.
However, if your furnace is 10–15+ years old, requires frequent repairs, or struggles during cold snaps, it may be wise to plan ahead rather than wait for a winter emergency.
How This Law Could Impact Replacement Costs + Availability
As manufacturers transition to Ultra Low‑NOx‑compliant equipment, homeowners may see:
- Fewer equipment options
- Shifts in pricing
- Longer lead times during peak heating season
Replacing a furnace during an emergency often limits your options. Planning ahead gives you control over timing, comfort, and budget.
