Metairie Weather and HVAC Load
NOAA's 1991-2020 climate normals put Metairie at 1,176 heating degree days and 3,205 cooling degree days per year. Cooling carries most of the load. Heating equipment gets light use, so a furnace here often outlasts the AC it's paired with. A normal year brings 5 nights at or below freezing and 85 days over 90°F.

Metairie Housing Stock
Half the homes in Metairie were built before 1972 (Census ACS median), so the typical house is about 54 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 61.8% of occupied homes, roughly 38,000 households. The median home value is $308,900, and median household income is $73,256. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Jefferson Parish show 6 hail days and 13 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.25 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Jefferson Parish also had 6 tornado days in that period. In Metairie, 21.3% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.
When Replacement Makes Sense
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- Gas or electric bills keep climbing even though usage hasn't changed
- A repair quote runs past a third of the cost of a new unit
- A tech found a cracked heat exchanger, or the CO detector has gone off
What Moves the Price
- BTU size, which should come from a Manual J load calculation
- Condition of the existing ductwork and any changes it needs
- New PVC venting if you move to a condensing model
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Single-stage, two-stage or modulating gas valve
- Permit and inspection fees, which the local building department sets
For Metairie we lowered the national figures about 9%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.

- The new furnace, filter rack and thermostat wiring
- The permit and the manufacturer warranty registration
- Combustion and safety tests
- Gas line and vent connections
Louisiana Permits, Efficiency Rules and Rebates
Louisiana is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Expect the contractor to pull a mechanical permit for a replacement job in Metairie. If a bidder suggests skipping it, move on. Also ask for a Louisiana license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
- Look up utility rebates on 95%+ AFUE units before you buy.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.

Furnace Replacement Questions from Metairie Homeowners
How much is furnace replacement in Metairie?
Plan on $2,900 to $7,100, with most jobs near $5,200. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule furnace replacement in Metairie?
Between late fall and early spring. With 85 days over 90°F, Metairie contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
How long does a furnace replacement take?
A straight swap is usually done in one day, somewhere between 4 and 10 hours. Moving to a condensing furnace with new PVC venting can add a few more.
Is a high-efficiency furnace worth it?
In cold climates, a 95%+ AFUE furnace usually earns back the price difference in lower gas bills. Where winters are mild, the payback can take a very long time.
