Top 7 HVAC companies in Jefferson, Louisiana

How to choose an HVAC contractor in Jefferson, Louisiana

Jefferson Parish sits in a cooling-dominant climate where latent loads dominate equipment sizing. Public listings supply the only available signals: star ratings, review counts, category descriptions and published availability. A Bayesian adjustment pulls every raw score toward the national mean of 4.764; companies with fewer than roughly twenty reviews therefore move closer to that mean. The resulting order favors firms that combine higher raw scores with website presence or 24/7 listing status. No data set here records completed jobs or complaint histories. Readers must still verify current LSLBC standing at arlspublic.lslbc.gov and confirm local permit rules with the jurisdiction where the work will occur.

The shortlist

Trane Supply

Trane Supply operates from 5400 Pepsi St # H, Harahan, LA 70123 and lists the phone number (504) 434-3833. Its single review produced a raw 5.0 that the model adjusted downward by 0.228 points to 4.772 because the sample size remains small. The listing shows a public website and no 24/7 claim. These signals place it first despite limited volume. The data cannot reveal whether the firm actually performs residential installations or only supplies equipment.

Mid-South Equipment Sales & Services

Mid-South Equipment Sales & Services sits at 5751 River Rd, Harahan, LA 70123 and can be reached at (504) 835-0422. Two reviews at 4.5 moved upward 0.248 points to an adjusted 4.748 once the model applied the national mean. The entry carries a general-contractor category and a website. Its position rests on those two modest reviews plus the website tie-breaker. Nothing in the record shows whether the firm maintains its own installation crews or subcontracts the work.

HVAC Pro

HVAC Pro lists 2261 N Causeway Blvd, Metairie, LA 70001 and the number (800) 471-1071. With zero reviews the raw score sits at 0, yet 24/7 availability lifts the adjusted rating to 4.764. The general-contractor category supplies the remaining ranking weight. The entry therefore occupies third place solely on availability. The figures give no information about actual service capacity or response times once a call is placed.

Baltodano Air Conditioning

Baltodano Air Conditioning operates from 1738 Broadway St, New Orleans, LA 70118 and answers at (504) 914-5506. One review at 5.0 receives an adjusted score of 4.772 after downward movement of 0.228 points. No website or 24/7 flag appears. Its rank follows directly from the single high rating and the absence of further tie-breakers. The record cannot indicate how frequently the firm handles residential change-outs versus commercial work.

Bert Leaveau Services, Inc.

Bert Leaveau Services, Inc. is located at 250 Jeannette St, Jefferson, LA 70121 and lists (504) 835-5149. A lone five-star review produces the same 4.772 adjusted score after the model pulls the raw 5.0 toward 4.764. The general-contractor category and lack of extra signals determine its fifth-place standing. Review volume this low leaves open questions about consistency across multiple jobs.

Coastal Air Balance Inc

Coastal Air Balance Inc appears at 4604 Jefferson Hwy, Jefferson, LA 70121 and can be called at (504) 834-4537. One review at 5.0 again yields an adjusted 4.772. No website or round-the-clock listing is noted. The position rests on that single rating and the general-contractor designation. The data set supplies no evidence of duct-testing credentials that the name might suggest.

Allen's 24-7 HVAC Service

Allen's 24-7 HVAC Service works from 128 8th St, Bridge City, LA 70094 and answers (504) 570-4878. Two reviews at 4.5 receive an adjusted 4.748 after an upward shift of 0.248 points. Published 24/7 availability supplies the decisive tie-breaker that keeps it in the shortlist. The general-contractor tag offers no further distinction. Low review depth still leaves performance variability unknown.

Cost

Modeled typical full-system installation cost stands at $8450, bounded by $7600 and $9300. The 2025 invoiced average reaches $16196, with the upper quartile at $25376. Labor is stated at $90 per hour and permit fees range from $100 to $350. The two cost sources therefore diverge sharply, the invoiced average roughly twice the modeled typical price. Readers comparing bids should request itemized labor, equipment and permit line items rather than rely on either aggregate figure. Both sources carry the explicit caveat that they reflect different data collection methods.

Licensing and permits

Mechanical work above $10000 in labor and materials requires a Louisiana State Licensing Board for Contractors license. The LSLBC issues Mechanical Contractor classifications that cover commercial classes A, B and C under La. R.S. 37:2150; the same license also authorizes residential HVAC. Minimum insurance is set at $100000 general liability plus proof of workers' compensation for residential applicants, although no specific workers' compensation coverage amount is mandated. Permits remain a local matter. Jefferson Parish and the City of New Orleans each run separate systems; the latter uses onestopapp.nola.gov in addition to the state license. Statewide licensure therefore governs contractor eligibility, yet the actual permit for any given job must be obtained from the jurisdiction where the equipment will be installed.

Incentives

Louisiana Home Energy Rebates remain conditionally approved with no launch date announced. Planned heat-pump incentives reach $8000. No state tax credit exists. Local utility programs through Entergy Energy Smart and Cleco offer $200-$1000 rebates, but only when work is performed by a participating contractor in the utility network. Federal 25C and 25D credits expired at the end of 2025, leaving no residential HVAC tax credit for 2026. The 48E commercial ITC survives under strict timing rules. These rules together narrow the installer pool: any homeowner seeking a rebate must first confirm the firm participates in the relevant utility program and holds the required LSLBC classification.

Climate

Jefferson Parish falls in IECC zone 2A with 1600 heating degree days and 2900 cooling degree days. Design temperatures run 34 °F in winter and 93 °F in summer. The load profile is strongly cooling-dominant, and the humidity regime is extreme. Equipment must therefore manage high latent loads; simple sensible-capacity sizing frequently leaves houses cold yet clammy. Duct sealing and proper refrigerant charge become primary failure points. Central air-conditioning saturation is near universal, and natural gas or electricity supplies the limited heating demand. Peak service season runs through the summer months.
