How Much Does a Gas Furnace Cost in 2024?

If the winter season reigns in your neighborhood, investing $3,750 to $9,800 in a robust gas furnace can make a difference in your home atmosphere. You can wave bye to power outages and overwhelming energy bills while keeping your home a cozy nest to live in. The average cost of a gas furnace for a 2,000-square-foot house is about $6,790. However, you can find much cheaper units and spend about $1,500 with installation included. Or you can go for a high-efficiency alternative backed by a warranty and shell out around $12,000. Once in place, severe winter storms won’t be that much of a concern.

Gas Furnace Replacement Cost Estimator

In some areas, natural gas is cheaper than electricity, meaning upgrading your home heating system with a gas furnace can be a cost-effective solution in the long run. Modern options can achieve an AFUE rating of 90% or higher, meaning they are highly effective in utilizing the energy they consume. Moreover, these units are known for their longevity and durability, often outlasting electric heaters. But how much does it cost to replace a gas furnace for your home? Below, we’ll navigate you through all price-shaping factors.

Gas Furnace Prices by Type

Whether a gas furnace installation will set you back $730 or $6,540 hinges much on the unit type. You can choose from three options available, each varying in initial cost and ongoing operational expenses. Top-notch, energy-efficient gas furnaces prices are higher upfront than standard models. However, with the spikes in utility bills, you can save a fortune in the long run. 

Single-Stage 

A single-stage gas furnace runs $730 to $3,300 per unit installed, making it a go-to choice for many homeowners. This type of furnace operates with straightforward functionality, featuring a single heat setting that works on a basic “on/off” principle. While this simplicity makes the single-stage furnace easy to use, it also means that the system is less efficient compared to more advanced models. As such, homeowners may struggle to maintain precise temperature control throughout their living space.

Two-Stage

A two-stage gas furnace price can land between $980 and $3,560. Improved energy efficiency and temperature control can compensate for the higher initial investment (compared to their single-stage counterparts). Dual-stage furnaces are designed to automatically adjust between high and low heat settings depending on the temperature demand. This feature helps maintain a more consistent and comfortable indoor environment and contributes to lower energy consumption. 

Modulating 

Modulating gas furnaces range from $1,300 to $6,540. This type represents a significant advancement in home heating technology, equipped with variable-speed blowers and a computer-controlled thermostat to manage heat distribution efficiently while minimizing fuel waste. Although these furnaces cost three to five times more than basic (one-stage) models, the investment can offset itself through substantial energy savings as time passes.

Natural Gas Furnace Cost by BTU

Gas furnaces are available in multiple sizes, aka capacity (40,000 to 150,000 BTUs), with costs spanning from $2,000 to $9,300 installed. Such a choice allows you to find an ideal option for your home size and heating requirements. The number of BTUs specified on the unit’s package informs you what space it can effectively warm up, given that each square foot of your home needs 30 to 60 BTUs. Hence, suppose you live in a mid-sized home of around 1,900 square feet. In this case, you should select a gas furnace model rated between 60,000 and 120,000 BTUs.

Mobile Home Gas Furnace Replacement Cost 

If you are on the lookout for a mobile home gas furnace, you should expect to fork out from $920 to $2,600. This price fluctuation largely depends on the brand and the level of energy efficiency each model offers. These mobile home-specific furnaces are evaluated based on their Annual Fuel Utilization Efficiency (AFUE) percentages, which can vary, generally from 80% to 95%. This means that the higher the efficiency, the more heat the furnace can generate from each gas unit, possibly reducing fuel costs. Downflow furnaces are predominantly used in mobile homes due to their structural compatibility, as the ductwork is installed beneath the floors, making downflow models a practical choice.

Gas Furnace Prices by Brand

The gas furnace’s capacity, efficiency level, and brand reputation determine the price range – $600 to $8,000 for a unit alone. Standard units manufactured by mid-market companies are more affordable upfront, but they can hardly boast advanced features or a 20-year warranty for main parts. Meanwhile, high-efficiency gas furnace pricing may seem unmanageable for homeowners with financial constraints. However, higher ratings often equate to lower operational costs over time. Thus, prioritizing long-term efficiency for greater savings can be a smart move to take.

**Royalton 88,000 BTU single-stage forced air natural gas furnace from $1,443, according to Home Depot

**American Standard 80,000 BTU 2-stage variable speed gas furnace from $4,848, according to MyHVACPrice

**Coleman 62,000 BTU mobile modular home gas furnace from $1,962, according to NorthAmericaHVAC

Gas Furnace Installation Cost

While installing a standard gas furnace incurs labor costs, ranging from $890 to $2,200, you can shell out $1,230 to $3,000 for a high-efficiency system. Hourly rates for a licensed HVAC contractor typically fall between $60 and $150, with an added cost of about $50 per hour for each assisting crew member. On average, they can install a basic gas furnace in 4 to 10 hours. However, the timeline can drag up to 15 hours for high-efficiency units due to their complex design and the need for additional vents.

Cost to Install a Gas Furnace by Additional Services

Installation (or replacement) of a gas furnace is often a multi-level process, requiring extra services to achieve the ideal result. Hence, when deciding how much money you need to set aside to complete the project, make room for the following add-ons.

Old Unit Removal 

Contractors can charge from $140 to $550 to remove and dispose of an old gas furnace. The fee is based on the unit’s dimensions, location within the house, and local regulations. Additional charges may be incurred if the gas furnace is situated in a difficult-to-access area. 

Permits 

If you are about to install a gas furnace for the first time, you will have to fork out from $380 to $1,500 for a professional inspection of the spot and getting a building permit. These mandatory inspections guarantee the safe operation of the soon-to-be-installed furnace. As the fee can fluctuate depending on the location and the selected inspector, you should take your time to locate the right one. 

Ductwork

Homeowners who don’t have ductwork in place have to budget from $460 to $2,100 to get one. On average, specialists charge $10 to $21 per linear foot. If you have worn-out ductwork, its replacement might be a smart move to make before a gas furnace installation. Leaks can result in a heat loss ranging from 10% to 30%. In general, you should have your ductwork inspected and cleaned at least once a year to maintain optimal performance and efficiency of your heating system. Cleaning services can set you back $280 to $500 but save you hundreds in the future.

Gas Furnace Conversion Costs

Homeowners often switch to gas furnaces due to their cost-efficiency and reliable heating capabilities. How much the conversion process will set you back depends on the type of existing furnace. For those with a propane furnace, the conversion to natural gas typically costs between $660 and $1,570, with the installation of natural gas lines included. 

If you now use an oil furnace, your outlay can be much higher—from $2,230 to $9,000—because of the project’s complexity. Technicians have to set up the natural gas infrastructure. Meanwhile, transitioning from an electric to a gas furnace usually costs between $1,830 and $5,350, involving furnace replacement and gas line installation.
