Start with licensing, not price
Any HVAC job over $10,000 in Louisiana legally requires a contractor holding the Mechanical classification through the State Licensing Board for Contractors, and smaller jobs may require home improvement registration instead. Ask for the license or registration number before scheduling an estimate, not after.
Verify the number directly with the LSLBC rather than trusting what's printed on a truck or invoice. A legitimate Shreveport contractor should have no problem with this request, and hesitation is a warning sign worth taking seriously.
Get multiple written quotes
Get at least three quotes for anything beyond a basic repair, and make sure each one specifies the exact equipment model and efficiency rating, not just a tonnage and a price. Quotes that are vague about the equipment are harder to compare and can hide a lower-quality unit behind a competitive price.
Ask each contractor to explain their load calculation for sizing the system rather than simply matching the old unit's tonnage. Correct sizing matters a lot in Shreveport's humid climate, since an oversized system cools quickly but doesn't run long enough to properly dehumidify the home.
Confirm permits and insurance
Ask directly whether the contractor will pull the required mechanical permit through the City of Shreveport's Permits and Inspections Division for the job, and get this commitment in writing as part of the contract rather than assuming it's included.
Also confirm the contractor carries general liability insurance and workers' compensation coverage, since Louisiana's licensing requirements include insurance minimums for residential contractors, and you don't want to be liable if a worker is injured on your property.
Watch for red flags
Be cautious of any contractor who pressures same-day replacement without giving you time to get a second opinion, especially during an emergency call in peak summer heat when it's easy to feel rushed into a decision.
Also be wary of quotes that seem unusually low compared to others, since this sometimes means lower-grade equipment, no permit, or hidden costs that surface later. A fair price reflects the actual scope of work, not just the lowest number on paper.
Questions to ask before signing
Ask what warranty covers both the equipment (typically manufacturer-backed) and the labor (contractor-backed), and get the terms in writing, since labor warranties vary widely between companies and matter more over the life of the system than the sticker price.
Ask how the company handles follow-up if something isn't right after installation, and check whether they're an approved provider for the SWEPCO HVAC incentive program if you're hoping to use that rebate toward the cost.
Common questions
How do I verify an HVAC contractor's license in Louisiana?
Contact the Louisiana State Licensing Board for Contractors directly or use their online verification tools to confirm the license number and classification match what the contractor provided.
How many quotes should I get for HVAC work in Shreveport?
Three is a reasonable standard for any job beyond a basic repair, giving you enough comparison to spot outliers in price or scope.
Should I be worried if a contractor doesn't mention permits?
Yes. Ask directly whether they'll pull the required mechanical permit for the job, and get the answer in writing before work begins.
What's a reasonable labor warranty on HVAC installation?
One to two years of labor coverage is common, though some contractors offer longer terms. Get the specific length and what it covers in writing.
Are online reviews reliable for choosing a contractor?
They're useful as one data point, but combine them with license verification and a written quote comparison rather than relying on reviews alone.
Can I ask a contractor to explain their load calculation?
Yes, and you should. A reputable contractor will walk you through how they sized the system for your home rather than just matching the old unit's tonnage.
