Property Managers: Colorado’s Furnace Regulations Are Now In Effect. Pre-Regulation Inventory Is Still Available.

Strategic guidance for multi-unit property portfolios | Updated January 2026

The 60-Second Summary

Colorado House Bill 23-1161 is now in effect as of January 1, 2026. Furnace replacement costs have increased by up to 200%, but there’s still a window to act.

Distributors stocked up on pre-regulation equipment before the deadline. While that inventory lasts, you can still get standard equipment at pre-regulation pricing. For property managers overseeing multiple units, this is a significant opportunity, but it won’t last forever.

This isn’t about panic. It’s about math, and acting while you still have options.

What’s Changed

As of January 1, 2026, all newly manufactured furnaces must meet one of two requirements:

  1. Ultra Low NOx (ULN) certification – Emissions below 14 ng/joule
  2. Energy Star certification – 96%+ AFUE, currently listed on the Energy Star website

Equipment manufactured before December 31, 2025 remains compliant at pre-regulation pricing, while inventory lasts.

The Cost Reality

Equipment cost comparison (equipment only):

Equipment Type 2025 Equipment Cost 2026+ Equipment Cost Increase
Standard furnace $2,200-$3,500 Not available N/A
Energy Star furnace $3,000-$4,000 $4,200-$5,600 +40-60%
Ultra Low NOx furnace Not widely available $5,500-$8,000+ +100-200%

Total installed costs (with labor and materials):

Equipment Type Total Cost Today (2025) Total Cost After Jan 1 (2026+)
Standard furnace replacement $4,500-$6,500 Not available
Energy Star replacement $5,500-$7,500 $7,000-$9,500
Ultra Low NOx replacement Not widely available $8,500-$12,000+
The key insight: Standard equipment is no longer being manufactured. Your options are: (1) pre-regulation inventory while it lasts, (2) Energy Star, or (3) Ultra Low NOx. Options 2 and 3 are at significantly higher costs.

These aren’t projections – this is based on manufacturer pricing shared with Colorado contractors.

Why Property Managers Face Greater Exposure

Volume Multiplies Risk

A homeowner with one furnace faces one potential cost increase. You’re looking at:

  • Multiple buildings
  • Multiple units per building
  • Multiple systems approaching end-of-life simultaneously

If 15 furnaces across your portfolio need replacement after pre-regulation inventory runs out, the cost difference could exceed $75,000-$150,000.

Tenant Expectations Don’t Change

When a furnace fails, tenants don’t care about regulatory cost increases. They care about heat. Emergency replacements after pre-regulation inventory is gone will cost more, take longer, and create tenant complaints either way.

Budget Cycles Don’t Align with Deadlines

Many property management companies set budgets in Q4 for the following year. If 2026 budgets don’t account for the cost increase, you’ll either face:

  • Budget overruns on emergency replacements
  • Deferred maintenance that frustrates tenants
  • Unplanned capital expenditures

The Strategic Calculation

Here’s the decision framework we’re recommending to our property management partners:

Act Now While Inventory Lasts If:

  • Equipment is 15+ years old – You’re likely within 2-5 years of replacement anyway
  • Multiple repairs in last 3 years – Signs of declining reliability
  • Tenant comfort complaints – Inconsistent heating, temperature swings
  • Properties scheduled for sale – Buyers will factor in equipment age

Hold and Monitor If:

  • Equipment is under 10 years old – Still has significant life remaining
  • No major repairs or reliability issues – Running efficiently
  • Recent efficiency upgrades – May qualify for Energy Star path when replacement is needed

Evaluate Carefully If:

  • Equipment is 10-15 years old – Case-by-case assessment based on condition
  • Mixed portfolio – Some urgent, some not

Your Action Plan

Step 1: Portfolio Audit

Identify your exposure:

  1. Pull equipment age data for all properties
  2. Flag all furnaces 15+ years old
  3. Note any systems with repair history in the past 3 years
  4. Identify high-priority properties (occupied, difficult access, high tenant sensitivity)
Step 2: Financial Analysis

Run the numbers:

Pre-Regulation Inventory Cost Post-Inventory Cost Difference per Unit
$6,000 $12,000 $6,000
$8,000 $15,000 $7,000
$10,000 $18,000 $8,000

Multiply by your unit count. That’s your exposure.

Step 3: Decision and Scheduling

Prioritize by:

  1. Age (oldest first)
  2. Reliability history (most repairs first)
  3. Tenant impact (occupied units first)
  4. Access complexity (difficult installations first)
Step 4: Execute

The inventory window is closing. Every week that passes means:

  • Less pre-regulation inventory available
  • More competition for remaining equipment
  • Risk of missing the opportunity entirely

The Inventory Reality

Colorado contractors can no longer order standard furnaces from manufacturers. Distributors saw this coming and stocked up. Carrier West, for example, loaded up on approximately $3 million in pre-regulation inventory, but that’s for their entire statewide distribution network. This inventory is still available, but when it’s gone, it’s gone. There won’t be more.

What About Properties That Don’t Need Replacement Yet?

Not everything in your portfolio needs immediate attention. For systems that are running well:

Document Current Status

  • Equipment age and model
  • Efficiency ratings
  • Recent maintenance records

Budget for 2026+ Reality

  • Plan for higher replacement costs in future budgets
  • Consider the Energy Star path (moderate increase vs. ULN premium)
  • Monitor Energy Star certification requirements – equipment must be currently listed, not just meet efficiency standards

Communicate with Ownership

Property owners need to understand:

  • Current equipment status
  • Future cost implications
  • Your recommended timeline

Common Questions from Property Managers

“Can we stockpile pre-regulation equipment?”

Technically, yes. But:

  • Storage requirements matter (temperature, humidity)
  • Warranties may be affected
  • You’re tying up capital in inventory

For most portfolios, scheduled replacement while inventory is available is more practical than stockpiling.

“What about electric alternatives?”

Heat pumps aren’t affected by ULN regulations (no NOx emissions). If properties are good candidates for electrification, this regulation doesn’t change your timeline – but it might make the comparison more favorable.

“How do we explain this to property owners?”

Lead with the financial exposure:

“The ULN regulations are now in effect, but pre-regulation inventory is still available. Replacing [X number] of aging systems while this inventory lasts saves approximately $[Y] compared to waiting. Here’s our recommended priority list based on equipment age and condition.”

“Is this real or contractor sales tactics?”

This is law. HB23-1161 is public record. The cost increases are based on manufacturer pricing – we’re not the ones setting equipment prices.

The Bottom Line for Your Portfolio

Portfolio Scenario Act Now (Pre-Reg Inventory) After Inventory Gone
5 furnaces, 15+ years Replace now: ~$30,000-$35,000 Wait: ~$60,000-$75,000
10 furnaces, mixed ages Replace 6 now: ~$36,000-$42,000 Wait on all: ~$100,000-$120,000

The numbers speak for themselves.
