Best HVAC and Plumbing Contractors in Chalmette, LA (2026)
Verified local service companies for St. Bernard Parish homeowners
GulfServicePros Editorial
Chalmette and the rest of St. Bernard Parish have a specific home services reality that sets them apart from the rest of the greater New Orleans area. The housing stock here rebuilt after Katrina with a combination of FEMA-constructed homes, elevated new construction, and restored pre-storm houses — all sitting in a parish with its own permitting office, its own inspection requirements, and its own contractor licensing environment. When something breaks, you want a contractor who knows this parish.
Here are the verified contractors currently serving Chalmette across HVAC, plumbing, and electrical — with real ratings and what each one does best.
HVAC contractors in Chalmette
Siener Air
4.7 stars · 40 reviews · 3924 Despaux Dr, Chalmette
Siener Air is Chalmette's most-reviewed HVAC contractor and covers the full range: installation, AC repair, and heating repair. For a St. Bernard Parish homeowner, having one contractor who handles both heating and cooling is more practical than the split-service model common in some larger markets. Siener's 4.7 rating across 40 reviews reflects consistent quality in the local market.
Coker Air & Heat LLC
5.0 stars · 28 reviews · 1000 E Josephine St, Chalmette
A perfect 5.0 rating across 28 reviews. Coker Air handles HVAC installation and heating repair — particularly useful in St. Bernard Parish where post-Katrina rebuild homes are now reaching the age where original HVAC systems need replacement. Josephine St. address puts them right in Chalmette's core service area.
Allied Air Conditioning & Heat, LLC
5.0 stars · 1 review · 8124 W Judge Perez Dr, Chalmette
Newer to the local review ecosystem but a perfect rating and a W. Judge Perez address that covers the full Chalmette corridor. HVAC installation specialists. Worth contacting for installation projects, especially if the other contractors above have extended lead times during peak season.
A&A Mechanical, LLC
5.0 stars · 1 review · 3106 Paris Rd, Chalmette
Covers both HVAC and plumbing — the combination that's useful when a renovation or new installation touches both systems. Paris Rd address in central Chalmette. For projects that involve both disciplines, having one contractor manage both avoids the coordination problem between separate HVAC and plumbing companies.

What home services cost in Chalmette
Chalmette pricing tracks closely with the wider New Orleans metro, typically running 5–10% below Orleans Parish rates for equivalent work.
HVAC installation: $5,500–$12,500 for a full system replacement on a standard St. Bernard Parish home. Post-Katrina elevated homes with accessible ductwork tend toward the lower end of that range.
AC repair: $185–$425 for standard electrical component failures. $400–$1,200 for refrigerant leak work.
Plumbing repair: $185–$450 for standard fixture and drain work. Pipe repair behind walls or under slabs runs $800–$3,500+.
Electrical repair/installation: $200–$600 for standard residential electrical work. Panel upgrades run $1,800–$3,500.
What makes St. Bernard Parish homes different
The most important fact about Chalmette's housing stock: approximately 98% of St. Bernard Parish homes flooded during Hurricane Katrina in 2005. The rebuild that followed produced three distinct home types that have different service implications.
Elevated new construction (2006–2015). The majority of rebuilt homes were elevated on piers or stems to meet the revised advisory base flood elevations. These homes often have mechanical equipment — HVAC air handlers, water heaters, electrical panels — installed in elevated utility closets or attic spaces rather than at ground level. Access is different from standard slab construction, and contractors unfamiliar with the configuration can take longer or quote more than necessary.
FEMA cottages and trailers converted to permanent homes. Some residents converted temporary FEMA housing to more permanent structures. These have non-standard configurations and often require contractors with experience in the specific construction type.
Restored pre-storm homes. Some older Chalmette homes were structurally intact enough to restore rather than rebuild. These have the older-home characteristics — aging wiring, original plumbing, pre-2000 HVAC systems — common to pre-Katrina construction, now approaching 20 years of additional age since the storm.
St. Bernard Parish also has its own building department at 8201 W Judge Perez Drive with its own permit and inspection process separate from Jefferson Parish or Orleans Parish. Any contractor working in Chalmette who pulls permits from the wrong parish or doesn't know the local inspection process is a flag.
How to choose a contractor in Chalmette
Verify Louisiana state licensing for the specific trade: mechanical license for HVAC, master plumber's license for plumbing, electrical license for electrical work. All verifiable at lslbc.louisiana.gov.
Confirm St. Bernard Parish permit knowledge. Any significant system work — HVAC replacement, panel upgrade, water heater replacement — requires a permit through St. Bernard Parish, not Orleans or Jefferson. A contractor who doesn't know this immediately is a concern.
Ask specifically about post-Katrina rebuild experience. Elevated homes, non-standard utility configurations, and the specific construction types common in St. Bernard Parish are not universal knowledge. A contractor who has worked extensively in Chalmette and Arabi knows things a New Orleans-focused contractor may not.
