You do not have to replace a working furnace or water heater just because the calendar reached 2026. Colorado’s law sets standards for covered new products. It is not an order to remove equipment already operating in your home.
What changed on January 1, 2026?
Colorado House Bill 23-1161 created emissions standards for certain new water heaters and fan-type central furnaces manufactured, distributed, sold, offered for sale, leased or offered for lease in Colorado on and after January 1, 2026. The law also added standards for certain new electric storage water heaters.
For homeowners, the practical change appears when covered equipment needs replacement: the new product must meet the applicable Colorado standard. Manufacturers, distributors and contractors have adjusted their available equipment accordingly.
Is Colorado banning gas furnaces or water heaters?
No. The law does not ban gas heating. Compliant gas furnaces and water heaters remain options. It changes which new models may be offered in Colorado by setting emissions limits and compliance requirements for covered equipment.
Do I need to replace equipment that still works?
No. The 2026 product standards do not create a replacement deadline for a furnace or water heater already in your home. If existing equipment is operating safely and reliably, you can continue using it. Normal safety, repair and local code considerations still apply.
If your system has a problem, start with a diagnosis. A repair may be practical, or replacement may make more sense based on equipment condition, safety, reliability, parts availability and total cost.
What should I expect when replacement is needed?
A good replacement plan should begin with the home—not a one-size-fits-all equipment quote. The contractor should review the existing system, capacity, fuel and venting, electrical needs, drainage, ductwork or piping, installation space and permit requirements.
- Ask for the exact model numbers in the proposal.
- Confirm the equipment is approved for the planned Colorado installation.
- Compare the complete installed scope, not only the equipment price.
- Review warranty, controls, venting and any required supporting work.
- Avoid replacing a working system solely because of a misleading “deadline” claim.
Should I replace early to avoid a future problem?
Not automatically. An older system with repeated failures, safety concerns or a major expensive repair may justify planned replacement. A dependable system with manageable operating costs may be better served by maintenance and a realistic replacement budget.

Where can I verify the rule?
The Colorado General Assembly’s enacted-bill summary explains the covered product standards, the January 1, 2026 date and the scope of the heating and water-heating requirements.
