New Orleans Housing Stock
The median New Orleans home dates to 1959, according to the Census ACS. That makes the typical house about 67 years old. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. Owners live in 50.5% of occupied homes, roughly 78,000 households. The median home value is $296,400, and median household income is $55,339. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Orleans Parish show 2 hail days and 17 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1 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. Orleans Parish also had 3 tornado days in that period.
Symptoms Worth a Service Call
- The blower won't stop running
- A yellow or flickering flame instead of a steady blue one
- The burners light, then shut off a few seconds later
- The thermostat calls for heat and nothing happens
- Banging, squealing or rattling from the furnace
What Moves the Price
- Which part failed: a flame sensor costs far less than a control board or blower motor
- The furnace's age and brand, which affect parts availability
- The diagnostic or service call fee
- Whether the part is still under the manufacturer warranty
- Night, weekend or holiday rates

Louisiana Licensing and Efficiency Rules
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). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Louisiana the company should carry a state license or registration. Ask for both.
Before You Hire
- Have the model and serial number from the furnace label handy. Parts get ordered faster.
- Check the filter, the thermostat batteries and the breaker first. Those three cause a surprising number of no-heat calls.
- Ask whether the diagnostic fee comes off the repair bill.
