It’s January 2026 or later, and you just found out your furnace or water heater needs to be replaced. The problem? Colorado’s new low-NOₓ law (House Bill 23-1161) is already in effect, and you’re not sure what your options are.
First things first: don’t panic. You’re not in trouble, you’re not being fined, and yes, you still have choices.
At Absolute Plumbing, Electrical, Heating & Air, we’ve been helping Denver-area homeowners navigate HVAC changes and emergencies for over a decade. Whether your system just gave out or you’re worried about navigating the new standards, we’ve got your back.
What the New Law Means (Now That It’s Here)
As of January 1, 2026, Colorado law prohibits the sale or lease of new gas-fired central furnaces and gas water heaters that don’t meet ultra-low NOₓ (nitrogen oxide) emission standards.
If your existing system is still working, you don’t need to replace it. But if you’re shopping for a new furnace or water heater, your options must meet the updated emissions guidelines.
The good news? There are compliant systems already on the market, including both gas and electric options, and we’re here to help you find the right fit for your home, budget, and comfort.
Step-by-Step: What to Do If You Need a Replacement Now
1. Confirm the System Has Truly Failed
Before jumping into a replacement, make sure it’s necessary. A full inspection from a licensed Absolute technician can:
- Diagnose the exact issue
- Check for safety hazards like carbon monoxide or leaks
- Let you know if repairs are possible (and cost-effective)
We offer same-day and emergency diagnostics across the Denver Metro area.
2. Define Your Priorities
Ask yourself:
- Do I need the fastest solution possible?
- Am I focused on long-term efficiency and savings?
- Is comfort or pricing more important right now?
Your answers will help us tailor a recommendation that fits your timeline and your household goals.
3. Choose Your Replacement Path
You have two main choices:
Compliant Gas Furnace or Water Heater
These systems meet Colorado’s NOₓ limits but still deliver the warmth and familiarity of natural gas. Ideal if you want minimal changes to your setup.
Electric & Heat Pump Alternatives
Heat pumps can handle both heating and cooling, and electric water heaters (especially heat pump models) are efficient and rebate-eligible. These may require minor infrastructure changes, but they offer long-term energy savings and cleaner performance.
4. Check for Installation Constraints
Before making a final decision, we’ll help you assess:
- Venting needs (gas models must vent safely to meet code)
- Electrical panel capacity (especially for heat pumps or electric upgrades)
- Space availability (some models may need additional clearance or airflow)
Absolute’s fully stocked trucks and expert technicians can often handle these adjustments same-day or within a short window.
5. Look Into Rebates & Financing Sooner, Not Later
Even post-deadline, there are incentives available that can help you offset costs:
Rebates
- Heat pumps and energy-efficient upgrades may qualify for utility rebates
- Colorado state programs may offer additional support based on system type and household income
Tax Credits
- The Inflation Reduction Act offers up to $2,000 in federal tax credits for qualifying installations.
Financing
- Absolute offers 0% APR for 60 months on select systems and flexible monthly plans for all qualified customers
The sooner we start the paperwork, the better positioned you’ll be to take advantage of available incentives.
Quick Myth-Busters: Clearing the Air
“I missed the deadline. Am I going to be fined?”
Nope! The law applies to the sale and installation of new systems. You won’t face penalties just for having an older system or needing a compliant replacement.
“I can’t get a gas furnace anymore.”
False. You can still buy a gas furnace, it just has to meet the new ultra-low NOₓ emissions standard.
“Can I buy a furnace online and have someone install it?”
Be cautious. Systems bought online may not meet Colorado codes, could void warranties, and may be more expensive to retrofit. It’s safer (and often cheaper) to work with a licensed, local team like Absolute.
