Memphis Weather and HVAC Load
NOAA's 1991-2020 climate normals put Memphis at 2,874 heating degree days and 2,313 cooling degree days per year. Neither season dominates in Memphis. That balance is a big reason heat pumps and dual-fuel systems sell well in Tennessee. Count on roughly 44 nights below 32°F and 72 afternoons past 90°F in a typical year. Snowfall averages about 3 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 45,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 2,874 |
|---|---|
| Cooling degree days / year | 2,313 |
| Nights at or below 32°F | 44 |
| Days above 90°F | 72 |
| Average low / high | 53.8°F / 73°F |
Memphis Housing Stock
The median Memphis home dates to 1970, according to the Census ACS. That makes the typical house about 56 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. Memphis has roughly 117,000 owner-occupied homes, or 46% of households. The median home value is $157,100, and median household income is $51,211. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 20 hail days and 47 days with damaging thunderstorm winds in Shelby County. The largest hail reported was 2 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage.
When Replacement Makes Sense
- The furnace is 15 to 20 years old or more
- A tech found a cracked heat exchanger, or the CO detector has gone off
- 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
What Moves the Price
- BTU size, which should come from a Manual J load calculation
- New PVC venting if you move to a condensing model
- Single-stage, two-stage or modulating gas valve
- Condition of the existing ductwork and any changes it needs
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Permit and inspection fees, which the local building department sets
We lowered the national figures about 16% for Memphis using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover
- Combustion and safety tests
- Removing and hauling away the old furnace
- The new furnace, filter rack and thermostat wiring
- The permit and the manufacturer warranty registration
- Gas line and vent connections
Tennessee Permits, Efficiency Rules and Rebates
Tennessee 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 Memphis. If a bidder suggests skipping it, move on. Also ask for a Tennessee 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
- 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.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.

Furnace Replacement Questions from Memphis Homeowners
How much is furnace replacement in Memphis?
Plan on $2,700 to $6,600, with most jobs near $4,800. 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 Memphis?
In spring or fall. Those are the slow months between heating and cooling season in Memphis.
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.
