At 8%, this gap is small enough that it's usually swallowed by normal quote-to-quote variation for furnace replacement — focus on the contractor, not the city.
Furnace replacement by type: Aurora vs Boulder
We localize each furnace replacement type separately for both metros, applying the same labor, climate and permit adjustments each time, so you're comparing like for like.
| Type | Aurora | Boulder |
|---|---|---|
| Gas furnace | $4,550–$8,350 | $4,200–$7,700 |
| High-efficiency gas furnace | $4,100–$8,350 | $3,800–$7,700 |

Furnace replacement by home size: Aurora vs Boulder
Furnace cost scales with the heating capacity (BTU) your home needs — roughly 40–45 BTU per square foot in a mixed climate. Larger homes need a bigger unit and more ductwork.
| Size | Aurora | Boulder |
|---|---|---|
| 1,000 sq ft (≈45,000 BTU) | $3,500–$6,350 | $3,250–$5,850 |

| 2,000 sq ft (≈90,000 BTU) | $4,700–$8,450 | $4,350–$7,800 |
| 2,500 sq ft (≈110,000 BTU) | $5,400–$9,650 | $5,000–$8,850 |
| 3,000 sq ft (≈130,000 BTU) | $6,100–$10,800 | $5,650–$9,950 |
| 3,500+ sq ft (≈150,000 BTU) | $6,800–$12,000 | $6,250–$11,050 |

What hvac pros earn in each metro
Labor is about 60% of a furnace replacement bill, so local wages drive most of the gap. These are real metro hourly wages for skilled installers (BLS OEWS), not estimates.

Cheapest time for furnace replacement in either city
Why spring and fall are cheaper: contractors have open calendar space and compete harder for the work. Why summer and deep winter are expensive: a broken system in extreme weather isn't optional, so you lose your negotiating leverage.
How much should you really budget for HVAC in 2026?
An HVAC budget isn't one number — it's a set of trade-offs between sizing accuracy, efficiency tier and brand. Our editors walk through how each one moves the price.
The efficiency-first case
In a hot-summer or cold-winter region, a higher SEER2/AFUE unit — or a heat pump — earns its premium back in lower bills, and utility and state rebates can still cut into the sticker (the federal 25C/25D credits ended Dec 2025). Run the payback math before defaulting to the cheapest box.
The budget-first case
Size the system to your home with a Manual J calculation and buy the standard efficiency tier (80% AFUE / 14.3 SEER2). In a mild climate the cheaper unit pays off because you rarely run it hard — paying for premium efficiency you won't use is the most common way to overspend.
The longevity case
The single biggest cost driver isn't the brand — it's correct sizing and install quality. A properly sized, well-commissioned mid-tier system with annual maintenance outlasts an oversized premium unit that short-cycles. Spend on the install, not the badge.
The costly errors in an HVAC job are a bad load calculation and a sloppy install — not the logo you chose. Size it with a real Manual J, let your climate set the efficiency tier, and claim whatever rebates you still qualify for.
