As you explore your options, it’s helpful to understand how pricing works. The total cost of a furnace depends on the fuel type, size, and efficiency rating—each playing a role in your system’s performance and long-term savings. While a lower upfront price might seem appealing, investing in energy-efficient equipment with dependable features and strong warranties often pays off over time.
At Done, we guide you through these choices with clear, upfront recommendations, helping you balance cost, efficiency, and comfort for the best overall value.
The expense of installing a furnace extends beyond the purchase price of the unit. Factors such as your home’s design, existing systems, and the complexity of installation all contribute to the overall cost. We provide transparent evaluations to ensure precise estimates.
Larger homes often require greater heating capacity due to their square footage and multiple levels. Homes with poor insulation or drafty windows may need more robust systems, while inefficient ductwork might call for design modifications to enhance performance.
| Home Size / Capacity | Recommended Furnace Size (BTU) | Notes |
|---|---|---|
| Small to mid-sized homes | 40,000–80,000 BTU | Suitable for most single-story or compact homes. |
| Larger homes | 90,000–120,000 BTU | Needed for bigger homes or those with high ceilings. |
| Multi-level / open layouts | Varies | May require advanced airflow features for even heating. |
Fuel type and local costs impact expenses:
Gas is economical in areas where it’s available, with modern gas furnaces providing dependable service. Electric systems are easy to install and suitable for milder climates, though costs vary with electricity rates. Oil is an option where gas is unavailable, but it necessitates proper tank maintenance.
| Furnace Type | Typical Installation Notes | Estimated Cost Range |
|---|---|---|
| Gas Furnace | Most common in Denver. Pricing varies based on efficiency (80–99% AFUE), venting requirements, and existing gas line condition. High-efficiency models may need new PVC flues or condensate drains. | $8,000–$14,000 |
| Electric Furnace | Easier to install if the home’s electrical panel can support it. Best for smaller homes or where gas lines aren’t available, though higher electricity rates can increase long-term costs. | $7,000–$12,000 |
| Oil Furnace | Less common in the Denver area. Requires an oil tank, venting, and regular maintenance. Installations are typically more complex and costly. | $9,000–$15,000+ |
High-efficiency models demand specialized venting and flues, while electrical upgrades might require new circuits or panel improvements. Limited installation spaces can lead to additional labor, and obtaining necessary permits and inspections is crucial for safety compliance.
| Efficiency Level (AFUE) | Description | Upfront Cost Impact |
|---|---|---|
| 80–85% (Standard Efficiency) | Converts 80–85% of fuel into heat. | Lower |
| 90–99% (High Efficiency) | Converts up to 99% of fuel into heat. | Higher |

A furnace is the main heating unit in many homes, responsible for generating warm air and circulating it throughout your living space. Most Colorado homeowners rely on natural gas furnaces, which heat air inside a combustion chamber and push it through ductwork using a blower motor.

The cost of a new furnace can vary based on the type of system you choose, its efficiency rating, the size of your home, and whether additional work is needed during installation. Many standard natural gas furnace installations range from a few thousand dollars to more, depending on features and performance.
