How Much Do Furnaces Cost?
When investing in a new furnace, it’s important to consider more than just the sticker price of the unit itself.
While the upfront equipment cost is a significant factor, the total investment for a properly functioning heating system includes installation, potential modifications to your ductwork, and additional accessories like thermostats or air purifiers.
On average, a new furnace installation in the U.S. typically ranges from $3,300 to $6,850. These figures are based on pricing data from top furnace providers, home improvement retailers like Lowe’s, and online HVAC suppliers such as HVAC Direct.
However, if you’re opting for a high-efficiency furnace—especially one with advanced features like variable-speed blowers, smart connectivity, or zoned heating—the total cost can climb significantly, sometimes exceeding $12,000.
These premium models offer long-term energy savings and greater comfort, but they do come with a higher initial price tag. Keep in mind that labor costs, local permitting, and system complexity can also impact your total investment.
Understanding the full scope of furnace installation costs helps homeowners make informed decisions and avoid unexpected expenses. Planning ahead ensures you choose a system that balances performance, efficiency, and value—providing warmth and peace of mind for years to come.

How Do You Choose the Best Furnace Companies?
Selecting the right company to install your new furnace is just as crucial as choosing the furnace itself.
1. Warranty Protection
Top-tier furnace companies offer robust warranty coverage that gives homeowners confidence in their purchase. Most leading brands provide a 10-year warranty on parts and a lifetime warranty on the heat exchanger, the core component of any furnace. Keep in mind, these warranties usually require annual maintenance to remain in effect.
2. Certification and Technician Training
Reliable furnace companies prioritize the training and certification of their technicians. Look for providers with North American Technician Excellence (NATE)-certified professionals—this certification is the industry’s benchmark.
3. Installation Accuracy and System Sizing
Reputable companies go beyond simply replacing your old unit. They conduct a Manual J load calculation to determine the right furnace size for your home, factoring in square footage, insulation, windows, and local climate.
4. Service and Maintenance Support
Installation is just the beginning of the relationship. The best companies offer maintenance plans that include routine inspections, priority emergency service, and discounted repairs. Look for providers with 24/7 support and clear, upfront communication about scheduling and costs.
5. Reputation and Local Experience
Although newer companies can provide solid service, long-standing businesses with at least 5–10 years of local experience tend to be more dependable. Check customer reviews across various platforms, and pay attention to how the company handles negative feedback.
6. Transparent Pricing and Financing
Trustworthy furnace companies provide detailed, written estimates that break down every cost. They’re willing to walk you through the quote and offer flexible financing options if needed. Be wary of providers who pressure you with limited-time offers or avoid giving clear pricing in writing.

1. Lennox
Lennox is recognized for its wide selection of furnaces, particularly those featuring variable-speed blower motors and noise-reducing technology.
The company’s origins trace back to 1895 in Marshalltown, Iowa, where founder Dave Lennox operated a small machine repair shop.
That same year, he acquired a patent for a new furnace design and established the Lennox Furnace Company, dedicating himself to refining the product.
His innovations laid the foundation for many of the advancements seen in modern heating and cooling systems.
With more than 100 years of industry experience, Lennox has built a reputation for producing reliable, high-performing furnaces.
The company continues to lead through innovation, focusing on enhanced energy efficiency, quiet operation, and advanced motor technology that allows for more precise and comfortable home heating.
2. Trane
Trane gas furnaces have a rich history, dating back to the late 1800s, and the company is widely regarded as one of the top names in the heating and cooling industry.
Founded in 1885 as a plumbing and pipe-fitting business, Trane didn’t begin manufacturing heating and cooling solutions until 1916.
A decade later, Reuben Trane, the son of founder James Trane, invented the convector radiator, a breakthrough that replaced the bulky cast-iron radiators of the time.
This innovation helped solidify the company’s reputation and contributed to its ongoing success. In 1984, Trane was acquired by American Standard.
Known for its commitment to innovation and reliability, Trane products are built for durability and efficiency, often featuring advanced technologies.
While Trane systems may come with a higher upfront cost, the investment pays off in the long term due to fewer repair and maintenance issues compared to many other brands.

In 1997, Goodman acquired Amana and retained only the HVAC portion of the business, selling the home appliance division to Maytag.
As a result, while Amana furnaces and air conditioners share the same brand name as Amana kitchen appliances, they are produced by different companies.
Amana has maintained a reputation for reliability and offers a comprehensive range of HVAC products, allowing consumers to source all their heating and cooling needs from one brand.
Amana furnaces are an affordable choice, providing a cost-effective alternative to higher-priced models like American Standard or Trane, making them a great option for those looking to upgrade their system on a budget.
