Top 7 HVAC companies in Orleans, Louisiana

Public listing data from August 2026 supplies the raw material for this ranking of HVAC contractors active in Orleans Parish. A Bayesian adjustment pulls every star rating toward the national mean of 4.764 so that small samples do not dominate. Additional points go only for a public website, an HVAC-specific listing category, or published 24/7 availability. The result is a shortlist, not an endorsement of workmanship.

Cost of HVAC work in Orleans

Modeled typical full-system installation sits at $8,450, bounded by $7,600 and $9,300. The 2025 invoiced average reached $16,196 while the upper quartile hit $25,376. Labor is published at $90 per hour. Permit fees range from $100 to $350. Both sources appear in the data; the invoiced average is roughly twice the modeled typical price. No totals or differences are calculated here because the figures come from separate collection methods. Homeowners should request itemized quotes that separate equipment, labor and permit costs.

The shortlist

Companies are ranked by a Bayesian-adjusted rating: a company's star rating is pulled toward the national mean until it has enough reviews to stand on its own, so a 5.0 from four customers does not outrank a 4.9 from two hundred. Small tie-breakers apply for a public website, for being listed as an HVAC specialist rather than a general contractor, and for published 24/7 availability. This is a shortlist built from public listing data, not a review of work performed.

Charlie's Heating & Air Conditioning

Seven reviews produce a raw 5.0 that the model adjusts downward to 4.809. The firm lists its address as 734 Iberville St, New Orleans, LA 70130 and can be reached at (504) 504-7662. Its general-contractor category and lack of 24/7 notation suggest daytime residential work only. The 0.045-point drop from raw score reflects the modest review count pulling the rating toward 4.764. Website presence supplied the tie-breaker that placed it first. These numbers say nothing about response speed during peak summer humidity.

Global Air - Refrigeration, Heating, & Cooling

Nine reviews at a raw 5.0 adjust to 4.818. The address is 2721 Burdette St, New Orleans, LA 70125; the phone is (504) 401-3445. The Services category plus published 24/7 availability supplied the tie-breaker that moved it above the next two 5.0 firms. The 0.054-point lift above the national mean occurs because the review count remains small. Nothing in the listing reveals whether the firm carries the Mechanical Contractor classification required for larger jobs.

New Orleans Heating & Air Conditioning

Seven reviews at 5.0 adjust to 4.809. Location is given as 3321 LA-46, New Orleans, LA 70117; calls go to (504) 420-1288. General-contractor status without 24/7 hours places it behind the prior firm despite identical raw scores. The 0.045-point decline from 5.0 follows directly from the Bayesian pull. The listing supplies no indication of dehumidification experience demanded by the local latent load.

Reyes Maintenance Services LLC

Six reviews at 5.0 adjust to 4.803. The address reads 438 Opelousas Ave, New Orleans, LA 70114 and the contact number is (504) 360-7080. General-contractor category without 24/7 availability explains the fourth-place slot. The 0.039-point drop from raw rating is smaller than for the firms above because the sample is even smaller. The data cannot show whether the firm routinely sizes for extreme humidity.

Air Conditioning New Orleans

One review at 5.0 adjusts to 4.772. The address is 2510 Eton St, New Orleans, LA 70131; the phone is (504) 565-2808. General-contractor status and no 24/7 hours place it fifth. The 0.008-point drop below the national mean occurs because a single review receives the strongest pull. The listing offers no evidence of prior work in the 2A climate zone.

New Orleans Air Conditioning & Heating

Thirteen reviews at 4.4 adjust upward to 4.654. Address is 924 S Dorgenois St, New Orleans, LA 70119; phone is (504) 358-2157. Published 24/7 availability supplied the tie-breaker that lifted it above the final firm. The 0.11-point rise toward 4.764 reflects the larger sample size. The numbers cannot reveal whether the lower raw score stems from humidity complaints.

New Orleans Heating & Air Conditioning

Twelve reviews at 4.3 adjust to 4.631. The address is 726 Adams St, New Orleans, LA 70118 and the phone is (504) 504-7857. General-contractor status without 24/7 hours fixes the last position. The 0.133-point rise from raw rating follows the Bayesian adjustment applied to a modest sample. The data supply no detail on moisture-management practices.

Licensing and permits in Orleans

The Louisiana State Licensing Board for Contractors issues mechanical licenses at the state level. A Commercial Mechanical license covers both commercial and residential HVAC work once the project value exceeds $10,000 in labor and materials. Below that threshold, residential registration applies. Minimum general liability coverage is set at $100,000; proof of workers' compensation is required for residential and home-improvement applicants, though no specific coverage amount is mandated for the latter. Permits themselves are issued locally. The City of New Orleans maintains its own mechanical licensing system through onestopapp.nola.gov in addition to the state requirement. Homeowners can verify any contractor at the public lookup maintained by the board.

Climate demands on HVAC systems

Orleans Parish lies in IECC zone 2A with a moist regime. Heating degree days total 1,600 while cooling degree days reach 2,900, confirming a strongly cooling-dominant load profile. Winter design temperature is 34 °F and summer design temperature is 93 °F. Extreme humidity makes dehumidification the controlling factor in equipment selection and duct design. Central air conditioning saturation is near universal, yet moisture management and duct sealing remain the primary failure points according to the engineering note. Heat pumps are rated excellent for the climate. Peak service demand occurs in summer. Oversizing for sensible capacity alone will leave houses cold yet clammy.

Incentives available in 2026

The Louisiana Home Energy Rebates program remains conditionally approved with no launch date. Planned heat-pump rebates reach $8,000. No state tax credit exists. Utility programs through Entergy Energy Smart and Cleco offer $200 to $1,000 per qualifying installation, but only participating contractors may submit claims. Federal 25C and 25D credits expired at the end of 2025; no residential HVAC tax credit applies in 2026. The 48E investment tax credit survives only for commercial or third-party-owned systems. These rules mean homeowners should first identify contractors already inside the Energy Smart network if they intend to pursue rebates.

How to choose an installer

Verify the LSLBC license class matches the job size. Confirm the firm participates in the relevant utility rebate program. Ask how the contractor accounts for latent load when sizing equipment. Request references from recent installations performed in the same humidity regime. Compare itemized quotes that separate equipment, labor and local permit fees. Check the public license lookup before signing any agreement.
