Kenner homeowners run their air conditioning harder and longer than almost anywhere else in the country. With summer temperatures routinely hitting 95°F and humidity pushing past 80%, your AC system isn't a seasonal appliance — it's essential infrastructure that runs nine to ten months a year. Choosing the right HVAC contractor in Kenner means finding someone who knows Jefferson Parish's housing stock, can pull permits through the parish, and will actually show up when your system quits on the hottest day of August.
We've compiled the top-rated HVAC companies currently serving Kenner, ranked by review volume and rating, with notes on what each one specializes in.
The best HVAC contractors in Kenner, LA
David LaVie's Air Conditioning, LLC
4.7 stars · 208 reviews · 2228 34th St, Kenner
One of the highest review volumes of any HVAC contractor in Kenner, which matters. A company that's been doing enough work to accumulate 200+ honest reviews has seen every type of system and every type of Kenner home. David LaVie's handles full HVAC installation and replacement — both standard ducted systems and ductwork retrofits common in older Jefferson Parish homes built before central air was standard.
Southland Air Conditioning & Heating Inc
4.6 stars · 193 reviews · 418 Veterans Blvd, Kenner
Another high-volume contractor with nearly two decades of reviews behind it. Southland covers the full service range — installation, AC repair, and air duct cleaning — which means you're not calling three different companies for three different problems. Their Veterans Blvd location puts them in the heart of Kenner's commercial corridor with fast response across the city.
Fin Mechanical Air Conditioning Service
5.0 stars · 105 reviews · 2929 Lausat St, Kenner
A perfect 5.0 rating across 105 reviews is a legitimate signal — not just a handful of friends reviewing a new business. Fin Mechanical specializes in AC repair and HVAC installation, and at that review volume and rating it's clear they're resolving problems correctly the first time. Recommended for both emergency repair calls and planned replacement projects.
Air Tight Construction, LLC
5.0 stars · 100 reviews · 3517 Causeway Blvd, Kenner
HVAC installation and replacement specialists. The name reflects their focus on building envelope work — proper equipment sizing, sealed ductwork, and installation that actually performs as specified rather than just technically completing the job. For Kenner homeowners replacing aging systems, the sizing and sealing work matters as much as the equipment itself.
Tegridy Air AC & Heating
4.9 stars · 67 reviews · 3517 Causeway Blvd, Kenner
Covers installation, AC repair, and air duct cleaning — a useful combination in Kenner where the ductwork in many older homes is both aging and leaking. Tegridy Air's 4.9 rating across 67 reviews puts it near the top of the local field on quality signals. A good option when you need both system work and duct inspection handled in one visit.
A & H Service Co. Inc.
4.8 stars · 58 reviews · 3517 Severn Ave, Kenner
Established Kenner HVAC contractor covering installation and AC repair. At 4.8 stars across 58 reviews, A&H has a consistent quality record in the local market. Good option for standard system replacement and repair work on Jefferson Parish residential properties.
Air Orleans AC, Heating and Air Quality
4.9 stars · 45 reviews · 3829 Loyola Dr, Kenner
One of the few Kenner HVAC contractors that explicitly covers air quality alongside HVAC installation, AC repair, and heating repair. For homeowners dealing with the combination of aging ductwork and Louisiana's persistent humidity and mold risk, having a contractor who handles both the mechanical and the air quality side in one appointment is genuinely useful.
La Grange AC & Heating
5.0 stars · 18 reviews · 3300 Loyola Dr, Kenner
Smaller review volume but a perfect rating. La Grange covers AC repair, heating repair, and HVAC installation. Worth considering especially if the larger contractors above are booked out — a 5.0 rating at 18 reviews suggests they're delivering quality work and the lower volume just means they're smaller, not worse.
What HVAC work costs in Kenner
HVAC pricing in Kenner generally tracks Jefferson Parish rates, which run slightly below New Orleans pricing for the same work.
AC repair: $185–$425 for standard electrical component repairs (capacitor, contactor). $400–$1,400 for refrigerant leak detection and recharge. $1,800–$3,500 for compressor replacement. Current local ranges and companies are on our AC repair in Kenner page.
HVAC installation (full system replacement): $5,500–$13,000 for a standard 3–4 ton ducted system. Mini-split installations run $4,000–$7,500 per zone — relevant for older Kenner homes that lack sufficient ductwork for a traditional central system. Compare installers on the HVAC installation in Kenner page.
Annual tune-up: $90–$200. The most cost-effective HVAC service you can schedule in Kenner — a spring tune-up that catches a failing capacitor before July is worth ten times its cost in avoided emergency-rate service calls.
Why Kenner homes need specific HVAC attention
Kenner's housing stock is predominantly mid-century construction — ranch homes and brick slab houses built between the 1950s and 1980s when Jefferson Parish was expanding rapidly around the newly completed interstate. These homes have three specific HVAC characteristics that set them apart from newer construction.
First, ductwork in these homes runs through unconditioned attics that reach 140°F+ in summer. Attic ductwork in a 40-year-old Kenner home loses 20–35% of conditioned air through seam leakage before it reaches the living space. A new system installed on old leaky ductwork performs at old-system efficiency. Any installation quote that doesn't mention ductwork inspection is incomplete — and if the ducts haven't been serviced in years, see air duct cleaning in Kenner before you size new equipment.
Second, the proximity to Lake Pontchartrain and the Mississippi River means Kenner has higher ambient humidity than inland Louisiana communities. Systems that are oversized — a common shortcut in the industry — cool quickly but don't run long enough to dehumidify. The result is a home that feels clammy even when the thermostat reads 72°F. Proper Manual J load calculation and two-stage or variable-speed equipment matters here.
Third, Jefferson Parish requires HVAC permits for system replacement. A contractor who doesn't mention permits is either working unpermitted (a liability for you as the homeowner) or planning to pull them without telling you. Either way, ask upfront.
How to choose an HVAC contractor in Kenner
Three things to verify before signing any contract:
Louisiana state mechanical license. Verify at lslbc.louisiana.gov. HVAC installation and significant repair work requires a licensed mechanical contractor in Louisiana. A contractor without current LSLBC credentials is working illegally and the work won't pass inspection.
Jefferson Parish permit. Any system replacement or significant modification requires a permit. Ask whether permits are included in the quote — they should be.
Written quote with line items. Equipment brand and model number, labor cost, permit fees, and any ductwork work identified. Verbal quotes that turn into larger numbers at installation are a common complaint in the local HVAC market.

Common questions
- How much does HVAC installation cost in Kenner, LA?
- A full HVAC system replacement in Kenner runs $5,500–$13,000 for a standard 3–4 ton ducted system in 2026. Mini-split installations run $4,000–$7,500 per zone. Pricing varies by system size, efficiency rating, and whether ductwork work is needed.
- Do HVAC contractors in Kenner need to pull permits?
- Yes. Jefferson Parish requires permits for HVAC system replacement and significant modifications. A contractor who does not mention permits is either working unpermitted — a liability for the homeowner — or pulling them without explanation. Always confirm permits are included in the quote.
- How do I verify an HVAC contractor's license in Kenner?
- Verify Louisiana mechanical contractor licenses at lslbc.louisiana.gov. Enter the contractor name or license number to confirm current active status. All HVAC installation work in Louisiana requires a state-licensed mechanical contractor.
- Why is my AC running constantly in my Kenner home?
- The most common causes in Kenner homes are aging attic ductwork with significant air leakage (losing 20–35% of conditioned air before it reaches rooms), an oversized system that short-cycles and fails to dehumidify, or a refrigerant leak reducing system capacity. A diagnostic service call from a licensed local contractor will identify which applies.
- What is the best time of year to schedule HVAC service in Kenner?
- Spring (March–May) is the best time for both tune-ups and system replacement in Kenner. Contractors have full availability, standard pricing applies, and you can address any issues before the summer demand peak hits. By July, most local HVAC companies are running multi-day backlogs for non-emergency work.
