If you’ve been putting off a furnace replacement, now is the time to act. Beginning January 1, 2026, new state regulations will require homeowners across Colorado to purchase Ultra-Low NOx or higher-efficiency Energy Star furnaces. These models are significantly more expensive than today’s standard options. By replacing your furnace before the end of 2025, you can save thousands of dollars and secure reliable heating for years to come.
What’s Changing in Colorado Furnace Regulations
In 2023, Colorado passed House Bill 23-1161, which limits emissions from residential gas furnaces statewide. Starting in 2026, no new standard gas furnaces can be sold, distributed, or installed unless they meet the following requirements:
- Ultra-Low NOx emissions: less than 14 nanograms of NOx per Joule.
- Energy Star certification: models must meet the latest efficiency standards.
That means the traditional 80% and 92% AFUE furnaces many Colorado Springs homeowners have relied on will soon no longer be available.
What This Means for Your Wallet
- Affordable options now – Standard furnaces are still available but only until late 2025.
- Higher costs later – Ultra-Low NOx furnaces use specialized burners, new technology,
and costly materials, making them thousands more expensive than standard models. - Limited supply – Once current inventory sells out, there will be no going back.
If you’ve been considering a Colorado furnace replacement, acting before year-end is the best way to save money.
Current Furnace Options in Colorado
- Standard NOx furnaces (80% and 92% AFUE): Available only through 2025.
