Colorado’s New Furnace & Water Heater Regulations
What Apple Aire Homeowners Need to Know
Colorado has introduced new low-emission standards for gas furnaces and water heaters, and many homeowners are wondering what this means for their home.
The most important thing to know is this:
If your current furnace or water heater is working safely, you do not need to replace it.
These new requirements only apply when new equipment is installed.

What Changed?
Beginning January 1, 2026, newly installed gas furnaces and gas water heaters in Colorado must meet updated low-NOx emission standards.
NOx, or nitrogen oxides, are emissions created when natural gas burns. Colorado’s updated standards are intended to help reduce emissions and improve air quality across the state.
This does not mean gas equipment is banned.
Homeowners can still install gas furnaces and gas water heaters. The equipment simply needs to meet the new Colorado standards.

How This Affects Replacement Costs
Because newer low-NOx systems use more advanced burner and combustion technology, equipment costs have increased across the industry.
For homeowners, this means furnace and water heater replacements may cost more than they did in previous years.
The good news is that many of these newer systems are also more efficient, which can help lower energy use and improve comfort over time.

Should You Replace Your System Now?
Not necessarily.
If your system is newer, safe, and running well, regular maintenance may be the best choice.
However, if your furnace or water heater is older, unreliable, or becoming expensive to repair, it may be smart to start planning before it fails.
Planning ahead gives you time to:
- · Compare equipment options
- · Review pricing before an emergency
- · Ask about available rebates
- · Choose the best system for your home
- · Avoid rushed decisions during extreme weather
