Replacing a furnace is usually a one-time project you plan around comfort, safety, and budget. The total price depends on the furnace type, efficiency level, and how much installation work your home needs.
Most homeowners want a realistic starting point before they request quotes. National cost ranges vary by fuel type and job complexity, but these estimates are commonly used for planning.
Use the table below for high-level planning, not as a quote.
| Furnace type | Common installation cost range |
|---|---|
| Electric furnace | About $2,000 to $7,000 |
| Gas furnace | About $3,800 to $10,000 |
| Oil furnace | About $6,750 to $10,000 |
These are planning ranges, not a quote. Your local labor rates, access to the equipment, and required upgrades can move the total up or down.
Two homes can get very different quotes for what looks like the same replacement. The difference usually comes from installation requirements.
Common cost drivers include:
A higher quote is often driven by labor time and required upgrades, not just the furnace price.
A clear quote helps you compare contractors and avoid surprise add-ons. You should be able to see what you are paying for and why.
A complete quote usually includes:
Before you sign, ask for the quote in writing and confirm what is included versus optional.
Efficiency is usually shown as AFUE, which stands for Annual Fuel Utilization Efficiency. It describes how much of the fuel’s energy becomes usable heat over a typical year.
Here is what matters for cost:
Efficiency can be worth it in the right climate and usage pattern, but it should be chosen with your installer based on your home and your local fuel costs.
Sometimes replacement is chosen because the existing furnace is near the end of its service life. Other times it is chosen because a major component failed and the repair cost is high.
Replacement often makes sense when:
A repair can still make sense when the furnace is newer, and the failure is limited to a replaceable part. A technician can help you compare repair costs against expected remaining life.
You can often lower the total cost by making better choices during the buying process, not by skipping safety or quality steps.
Practical ways to manage cost include:
If you plan to use a tax credit, confirm eligibility before you buy. Do not assume a furnace qualifies just because it is “high efficiency.”
A new furnace still needs basic maintenance. The goal is to keep airflow steady and reduce unnecessary strain on blower components.
In the first week after replacement:
Ongoing basics that support airflow:
If you want a simple way to stay consistent, Filterbuy sells HVAC filters in many standard sizes and custom sizes and offers Auto Delivery for scheduled replacements. Filterbuy also provides free shipping within the U.S. and filters are purely American-made.
Many homeowners see totals from a few thousand dollars to around ten thousand dollars, depending on fuel type, efficiency, and installation work. Gas and oil installations often cost more than electric.
The biggest drivers are furnace type, efficiency level, venting requirements, access to the unit, and whether your home needs electrical or gas line work.
Yes. If ducts need resizing, sealing, or repairs for proper airflow, that can add labor and materials. If your ducts are in good shape, you may not need changes.
Many areas require permits for furnace replacement, especially for gas equipment. Your contractor should confirm local requirements and include permit costs if needed.
Many standard replacements take about one day. Jobs that need major venting changes, electrical upgrades, or difficult access can take longer.
High efficiency models can reduce fuel use, but they can cost more upfront and may require different venting. The best choice depends on your climate, run time, and local energy prices.
Follow the system and filter guidance, but many households check monthly and replace on a regular schedule. If the filter loads quickly due to pets, dust, or heavy runtime, replace it sooner.
