2024 Furnace Installation Cost Breakdown in Aurora
Pricing for furnace installation in the Denver-Aurora-Lakewood metro area varies based on the fuel source, efficiency rating, and the complexity of the vent configuration. In 2024, the average cost for a professional installation typically ranges from $4,500 to $9,500.
| Furnace Type | Average Efficiency (AFUE) | Estimated Installed Cost (2024) |
|---|---|---|
| Standard Gas Furnace | 80% – 82% | $4,200 – $6,000 |
| High-Efficiency Gas Furnace | 95% – 98% | $6,500 – $9,800 |
| Electric Furnace | 100% (High Op-Cost) | $3,500 – $5,500 |
| Dual Fuel (Hybrid) System | Varies | $9,000 – $14,000 |
It is important to note that Aurora’s elevation—roughly 5,400 feet—requires specific adjustments to the furnace’s gas pressure and orifice size to ensure safe, complete combustion. Ignoring these high-altitude calibrations can lead to premature heat exchanger failure.
Why Efficiency Matters: 80% vs. 96% AFUE
The Annual Fuel Utilization Efficiency (AFUE) rating tells you how much of the energy in the fuel becomes heat for your home versus how much escapes through the flue. In Colorado’s climate, upgrading to a high-efficiency model often pays for itself through lower monthly utility costs.
| Feature | 80% AFUE (Standard) | 96% AFUE (High-Efficiency) |
|---|---|---|
| Venting Requirements | Metal chimney/B-vent | PVC pipe through side wall |
| Combustion | Open (uses indoor air) | Sealed (uses outdoor air) |
| Operational Noise | Moderate | Very Low (Multi-speed fans) |
| Estimated Monthly Savings | Baseline | 15% – 20% Reduction |
The Importance of a Manual J Load Calculation
One of the biggest mistakes contractors make is “rule of thumb” sizing based on square footage alone. A professional installation must include a Manual J Load Calculation. This technical assessment considers:
- The orientation of your home relative to the Colorado sun.
- The quality and R-value of your insulation.
- The number and type of windows (crucial for homes in older parts of Aurora).
- Local climate data provided by The Department of Energy.
An oversized furnace will “short cycle,” leading to excessive wear and tear, while an undersized unit will never keep you warm during a February blizzard.

Aurora Local Rebates and Financing Options
Aurora residents have access to several programs that can significantly offset the upfront cost of a new system. By choosing high-efficiency equipment, you may qualify for:
- Xcel Energy Rebates: Cash-back incentives ranging from $200 to $1,000+ for high-efficiency furnaces and heat pump installations. You can view current offers on the Xcel Energy Rebate Page.
- Federal Tax Credits (25C): Under the Inflation Reduction Act, homeowners can claim 30% of the project cost (up to $600 for furnaces) as a tax credit.
- Manufacturer Incentives: Brands like Lennox and Carrier frequently offer seasonal rebates for Aurora homeowners.
We also offer flexible HVAC financing to help you manage the cost of an unexpected emergency furnace replacement.

Frequently Asked Questions
How long does a furnace installation take?
Most installations in Aurora homes are completed within 4 to 8 hours. If we are performing a dual-fuel conversion, it may take slightly longer.
Should I replace my AC at the same time?
If your AC is more than 10 years old, it is often more cost-effective to replace both units simultaneously. This allows for a matched system that operates at peak efficiency. Learn more in our Repair vs. Replace AC Guide.
Do you offer emergency services?
Yes. If your furnace fails in the middle of a sub-zero night, we offer no-heat emergency service to get your home back to a safe temperature immediately.
