Heating and air conditioning repair in New Orleans
Our guide to heating and air conditioning repair covers how the job works. Below: the New Orleans numbers a HVAC contractor looks at, with sources.
What the housing in New Orleans tells a provider
The median home in New Orleans dates from 1960, so about half the housing is that old or older. By median year built, homes here are older than in 40 of the 56 other cities we cover. Older homes here often have ducts and venting that were sized for a different system.

Heating and cooling load in New Orleans
Cooling load in New Orleans comes to roughly 3,292 cooling degree days in a normal year (NOAA 1991-2020 normals). Measured at the New Orleans Lakefront Ap (LA) station. The cooling load here is higher than in 50 of the 56 other cities we cover. Cooling demand at that level is why the outdoor unit's size and condition matter here.

FEMA's National Risk Index lists Orleans Parish, LA as relatively high for cold wave risk. 19 of the 53 other cities we cover sit in counties with the same cold wave rating. A cold wave also stresses pipes and venting near the furnace, worth a look during a tune-up.
