How Much Does a New Furnace Cost? Best Price Guide for Las Vegas Homeowners

A new gas furnace usually costs about $3,500 to $8,000 installed for a typical home, with high efficiency models and complex installs costing more. The price depends on the furnace size, its efficiency rating, single stage or variable speed operation, venting changes, where it sits in the house and permit costs. These are general market ranges, not a quote.

In Las Vegas, furnaces run only a few months a year, so they often outlast the AC. Many owners only face this decision when a heat exchanger cracks or the furnace is well past 15 years. That makes it worth comparing a new furnace with a heat pump before you buy.

What Changes the Price of a New Furnace?

These factors move most quotes.

Size

Furnaces are sized in BTU per hour. Las Vegas heating loads are small compared with cooling loads. An oversized furnace short cycles and wears faster. See what is BTU.

Efficiency

AFUE measures how much fuel turns into heat. An 80 percent AFUE furnace sends about 20 percent of the fuel energy out the flue. A 95 percent model wastes far less. The U.S. Department of Energy explains furnace efficiency ratings.

Is high efficiency worth it in Las Vegas?

Because heating seasons are short here, the payback on a high efficiency furnace is slower than in cold climates. Many valley homeowners choose a standard efficiency furnace or a heat pump instead.

Venting and location

High efficiency furnaces need PVC venting and a condensate drain. Attic furnaces and tight closets add labor.

Gas line and permits

Gas line updates, a new shutoff and permit fees can add to the total.

Should You Buy a Furnace or a Heat Pump?

In Las Vegas, a heat pump is often the stronger option if your AC is also old. One heat pump can replace both the AC and the furnace. Our comparison in heat pump vs AC walks through the choice.

When a new furnace makes sense

• Your AC is newer and healthy
• You want gas heat
• The furnace failed and the AC has years left

When Is Furnace Replacement Necessary?

A cracked heat exchanger is the clearest case. It can let combustion gases into the air you breathe. A technician should shut the gas off and show you the damage.

Other signs

• Age past about 15 years. ENERGY STAR suggests considering replacement for furnaces older than 15 years.
• Repairs every winter
• Yellow or flickering burner flames
• Rising gas bills without a change in use
• Carbon monoxide alarms

How Do You Stay Safe With a Gas Furnace?

Carbon monoxide is the main risk. Install CO alarms near sleeping areas and on each level. The U.S. Consumer Product Safety Commission recommends yearly inspection of fuel burning appliances.

How Do You Compare Furnace Quotes?

2. Venting changes and condensate drain
3. Gas line work and shutoff
4. Permit and inspection
5. Thermostat compatibility
6. Labor and parts warranty

A Typical Las Vegas Case: The Furnace That Only Needed an Igniter

An owner expected to replace a 12 year old furnace that would not light. The hot surface igniter was cracked. The heat exchanger and venting checked out fine.

A new igniter and a flame sensor cleaning had the furnace running the same day. Replacement can wait until there is a real reason, like a cracked heat exchanger.
