Shreveport Weather and HVAC Load
Shreveport logs 2,067 heating degree days and 2,676 cooling degree days in a normal year, based on the closest NOAA weather station. Neither season dominates in Shreveport. That balance is a big reason heat pumps and dual-fuel systems sell well in Louisiana. On average, Shreveport gets 30 freezing nights and 98 days above 90°F per year. For a 2,000 sq ft house, this climate points to a heating load somewhere near 40,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

| Nights at or below 32°F | 30 |

Shreveport Housing Stock
The median Shreveport home dates to 1973, according to the Census ACS. That makes the typical house about 53 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. Shreveport has roughly 41,000 owner-occupied homes, or 53.8% of households. Homes here have a median value of $178,100 and households a median income of $48,465. Those two numbers drive the labor adjustment in our estimate.
Caddo Parish had 22 hail days and 54 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 3 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. Caddo Parish also had 15 tornado days in that period.

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). Plan on a mechanical permit for most replacements in Shreveport; the contractor normally pulls it. Before you sign, ask each bidder for their 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 every bidder quote the same efficiency ratings, or the prices won't compare.
- Replacing both pieces at once usually costs less than two separate jobs a few years apart.
- Ask for a duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.
