How to Choose an HVAC Contractor in Alabama

By Chad Wiswall, Owner & Lead HVAC Technician, Alabama HVAC License #92244

A new HVAC system is one of the biggest single purchases a homeowner ever makes outside of the house and the car. A repair or installation done wrong can cost you thousands in re-do work, premature failure, voided manufacturer warranty, comfort problems for years, and in the worst cases a real safety issue (gas line, electrical, refrigerant handling). And the contractor you pick has more impact on the outcome than the brand of equipment you choose. This guide tells you how to verify a contractor in Alabama before you sign anything. License lookup steps, insurance requirements, what BBB accreditation actually means, how to read reviews, the red flags to walk away from, and the green flags of a contractor you can trust. I have been running Chad's AC Direct in Central Alabama since 1993, and I have seen every version of this go right and wrong. This guide is part of our complete guide to HVAC in Central Alabama.

Alabama HVAC license verification

Alabama requires anyone performing HVAC work (heating, air conditioning, refrigeration) for hire to hold a current license issued by the Alabama Board of Heating, Air Conditioning, and Refrigeration Contractors (the HACR Board). The license is not a marketing claim. It is a state-issued credential that proves the contractor passed an exam, carries the required insurance, and meets the experience requirements set by Alabama law (Title 34, Chapter 31A of the Code of Alabama).

Hiring an unlicensed contractor is illegal in Alabama, and it exposes you to real risk:

No recourse if the work is defective
Often voids your homeowner insurance coverage if the work causes damage
Voids most equipment manufacturer warranties
No accountability if the contractor does not pay subcontractors or suppliers (mechanic's lien risk against your house)

How to verify any Alabama HVAC contractor's license, step by step:

Ask the contractor for their license number directly. A licensed contractor will give it to you without hesitation and it should appear on their truck, their business card, their website, and any written estimate.

Go to the Alabama HACR Board's online license lookup. The official URL is https://hacr.alabama.gov/ (Alabama Board of Heating, Air Conditioning, and Refrigeration Contractors). Look for the "License Search" or "Licensee Search" tool.

Enter the license number or the business name. The lookup will return the contractor's current license status, the class of license they hold (residential, commercial, refrigeration, or limited), the issue date, the expiration date, and any disciplinary actions on the record.

Verify the license is CURRENT (not expired) and ACTIVE (not suspended, revoked, or in disciplinary status).

Verify the license class matches the work you are hiring for. Residential HVAC work requires a residential license. Commercial work requires a commercial license. Some contractors hold both.

For reference: Chad's AC Direct holds Alabama HVAC Contractor License #92244, current and in good standing, residential class. You can verify it yourself using the steps above.

If a contractor will not give you a license number, or the number they give does not return a current active result on the HACR Board lookup, do not hire them. There is no acceptable explanation.

Why the license matters more than the marketing

Marketing tells you what a contractor wants you to believe. A license tells you what the state of Alabama has verified.

A licensed contractor has:

Passed the Alabama HACR Board exam, which covers refrigeration cycle theory, electrical fundamentals, gas code, ventilation code, ductwork sizing, building code basics, and Alabama-specific regulations
Documented at least 3 years of qualifying HVAC experience under another licensed contractor (the standard experience requirement, with some variations by license class)
Provided proof of general liability insurance to the state at minimum required levels
Provided proof of workers' compensation coverage if they have employees
Submitted to a background check
Paid the licensing fee and committed to ongoing continuing education

An unlicensed contractor has not done any of those things, and the state has no enforcement leverage against them if your job goes wrong.

The license alone does not guarantee good work (a licensed contractor can still do bad work, and you have the BBB and the license board as recourse if they do), but the absence of a license guarantees you are taking on much higher risk than you need to.

Insurance and bonding: what to ask for

Beyond the license, every HVAC contractor you hire should carry two specific insurance coverages. Ask for proof in writing before any work starts.

General liability insurance. This protects you, the homeowner, if the contractor or their crew damages your property during the job. Recommended minimum: $1 million per occurrence. Lower than that and a serious incident (a fire, a flood from a refrigerant line cut, a structural issue) could leave you holding the bag. Ask the contractor to have their insurance provider send a Certificate of Insurance (COI) directly to you, listing your property address as a certificate holder if possible.

Workers' compensation insurance. This protects you if a worker is injured on your property. In Alabama, contractors with 5 or more employees are legally required to carry workers' comp. Even contractors with fewer than 5 employees should carry it voluntarily, because if a worker is hurt on your property without coverage in place, you can be held liable as the property owner. Ask for proof.

Bonding. A surety bond is separate from insurance. It is a financial guarantee that protects you if the contractor takes your money and does not finish the job. Bonded contractors carry a surety bond (typically $10,000 to $50,000 in Alabama for HVAC work) and you can file a claim against the bond if the contractor breaches the contract. Not every Alabama HVAC contractor is bonded, but bonded is better than unbonded for large jobs.

If a contractor cannot produce current proof of general liability AND workers' compensation, do not hire them. No exceptions.

BBB Accreditation and what it really means

The Better Business Bureau (BBB) is a private nonprofit, not a government agency. BBB accreditation means a business has paid the membership fee, met the BBB's published standards, and agreed to the BBB's dispute resolution process. It is not a regulatory credential and the BBB cannot revoke your right to do business.

That said, BBB accreditation tells you something real:

The business has been in operation long enough to be evaluated (usually 6+ months)
The business has agreed to address complaints filed through the BBB process
The business meets standards on advertising claims, transparency in business practices, and licensing
The business has had its public-facing claims reviewed for accuracy

The BBB rating (A+ down to F) is calculated from complaint history, complaint resolution rate, transparency, time in business, advertising practices, and government actions. An A+ rating typically means very few complaints relative to size, fast and satisfactory complaint resolution, transparent business practices, and a long history of operation.

BBB ratings are public. You can search any business at bbb.org and see their accreditation status, current rating, complaint history (including resolved and unresolved complaints), and customer reviews left through the BBB itself.

For reference: Chad's AC Direct is BBB Accredited with an A+ rating.

When you are checking a contractor's BBB profile, look beyond the letter grade. Scan the actual complaints. Look for patterns. One complaint over 10 years is statistical noise. Twelve complaints in 18 months all about the same issue (unfinished installs, refusal to honor warranty, billing disputes) is a pattern. The BBB profile tells you whether complaints were resolved and how.

Google reviews: how to read past the star rating

Star ratings are easy to game. The number of reviews, the recency of reviews, and the contractor's response pattern are much harder to fake.

Volume. A single 5-star review means almost nothing. A hundred reviews at 4.7 stars tells you the business has actual operating history and the rating is statistically meaningful. Look for contractors with at least 100 reviews if they have been in business more than 5 years, and ideally several hundred. A contractor that has been operating for 20 years but only has 30 Google reviews is a flag. Either they are not asking customers for reviews (which suggests an undeveloped customer experience process) or customers are not motivated to leave them.

For reference: Chad's AC Direct has 1,247 Google reviews at 4.9 stars (as of May 2026).

Recency. Reviews from 6 years ago tell you what the business used to be. Reviews from the last 6 to 12 months tell you what it is now. Many businesses change ownership, change management, or have crew turnover that affects quality. Look at the most recent 20 to 30 reviews specifically. Sort by newest first on the Google Maps profile.

Detail. Vague 5-star reviews ("Great service! Highly recommend!") are common and could be friends, family, or solicited reviews from happy customers who do not have much to say. Detailed reviews that mention specific employees by name, specific work that was done, specific issues that came up and how they were handled, and specific outcomes are much more credible. Look for the detail.

Response pattern. How a business responds to negative reviews tells you who they are. The right pattern is: every negative review gets a response, the response acknowledges the issue, the response offers a specific path to resolution, and the response is not defensive. A contractor who argues with reviewers, blames the customer, or ignores negative feedback is showing you who they are when things go wrong.

Red flag patterns in reviews.

Multiple reviews mentioning "tried to upsell me on a system I did not need"
Multiple reviews mentioning "quote changed once they were in the house"
Multiple reviews about no-show appointments or rescheduled jobs
Multiple reviews about poor communication after the install
Negative reviews that have no response from the business

7 red flags that signal you should walk away

Red flag 1: No license number on the truck, business card, website, or quote. Or the contractor refuses to provide it when asked. Walk away.

Red flag 2: Door-to-door cold sales. A contractor who shows up at your door without an appointment, especially one claiming to be "in the neighborhood" and offering a "free inspection" or "promotional rate," is almost never the right hire. Reputable contractors do not run door-to-door sales operations.

Red flag 3: Pressure to sign today. "This price is only good if you decide today" is a sales tactic, not an honest business practice. Real HVAC pricing does not move that fast. Any contractor pressuring you to sign on the spot is using urgency to bypass your judgment.

Red flag 4: No written estimate. Verbal quotes are not contracts. You need a written, itemized estimate that specifies the equipment (brand, model number, tonnage, efficiency rating), the work to be performed, the warranty terms, the payment schedule, and the start and completion dates.

Red flag 5: Cash-only or large upfront deposit demanded. A reputable contractor will accept multiple payment methods (check, card, financing through a real lender like Wells Fargo or Synchrony) and will typically ask for a reasonable deposit (10 to 30 percent of total) at scheduling, not full payment upfront.

Red flag 6: Quote is dramatically lower than competitors. If three contractors quote $11,500 to $14,000 for the same work and a fourth quotes $7,500, that fourth quote is hiding something. Common dodges: using off-brand or used equipment, skipping the permit, undersizing the system, eliminating warranty coverage, planning to add scope after the install starts.

Red flag 7: No physical address. A contractor with no physical office, just a phone number and a website, is a flag in 2026. Lead-gen networks and out-of-state aggregators dominate the top of Google for emergency HVAC searches in Alabama, and they sell your call to whoever is paying for the lead that hour. You think you are calling a local Montgomery HVAC company; you are actually calling a national call center that may dispatch a different contractor every time. Always verify the contractor has a real physical address in Alabama.

7 green flags of a contractor you can trust

Green flag 1: Current Alabama HVAC license, easily verifiable. They tell you the number, it is on every document, and the HACR Board lookup confirms current active status.

Green flag 2: Long operating history in the local area. Years matter. A contractor who has been operating in the same area for 10, 20, 30+ years has accumulated reputation. Bad operators do not survive that long in a connected community. For reference, Chad's AC Direct has been operating in Central Alabama since 1993, 33 years.

Green flag 3: Owner-operator or owner-involved. When the owner answers the phone, signs the quote, or shows up on the install, accountability is built in. National chains and acquired multi-location operators often have absent ownership, which changes the incentive structure.

Green flag 4: Family-owned and family-operated. Not a guarantee of quality, but a family business has reputational stakes that a corporate chain does not. The owner's name on the door usually means the owner cares.

Green flag 5: No commission sales. Many of the worst HVAC sales experiences come from commissioned salespeople who get a percentage of the system they sell you. The pressure to upsell is structural. Contractors that pay technicians on hourly or salary basis, not commission, have a fundamentally different sales conversation with you.

Green flag 6: Detailed written estimates and clear warranty terms. A real estimate specifies the equipment, the labor, the warranty, the payment terms, and the timeline. You can read it and understand exactly what you are paying for.

Green flag 7: Strong review profile across multiple platforms. Not just Google. Look at BBB, Facebook, and Angi/HomeAdvisor as well. Consistency across platforms is harder to fake than a single-platform reputation.

Sample questions to ask before hiring

Print this list and ask every contractor you interview:

What is your Alabama HVAC license number? (Verify on the HACR Board lookup before going further.)
Are you BBB accredited? What is your current rating?
How long have you been in business in this area?
Are you the owner, or who owns this company?
Are your technicians paid hourly or on commission?
Can you provide a current Certificate of Insurance for general liability and workers' compensation?
Will you give me a written, itemized estimate with equipment model numbers and warranty terms?
Do you pull the required permits for installation work?
How long is the labor warranty? What does it cover? What voids it?
What is the manufacturer warranty on the equipment? Are you a factory-authorized installer?
Who handles warranty claims if the equipment fails in year 6?
Do you do the Manual J load calculation as part of the quote?
Will the same crew that installs the system also be available for service calls after?
Can I see 3 references from customers in my neighborhood or zip code?
What is your policy if the work needs to be redone for any reason?

Any contractor who hesitates, dodges, or gets defensive on any of these questions is showing you who they are. The right contractor answers all of them clearly and welcomes the conversation.

Frequently asked questions

Q: How do I verify an Alabama HVAC license?

A: Go to the Alabama Board of Heating, Air Conditioning, and Refrigeration Contractors website at hacr.alabama.gov, find the License Search tool, enter the contractor's license number or business name, and verify the license is current and active. The lookup will also show any disciplinary actions on record.

Q: Is BBB accreditation required for HVAC contractors in Alabama?

A: No. BBB accreditation is voluntary and private. The required state credential is the Alabama HACR Board license. BBB accreditation is a useful additional signal of business practices and complaint resolution, but it is not the regulatory standard.

Q: How much should I pay as a deposit for HVAC installation?

A: Typical industry practice is 10 to 30 percent at scheduling, with the balance due on completion. Be cautious of contractors demanding 50 percent or more upfront, or full payment before work starts.

Q: Do I need to pull a permit for HVAC installation?

A: In most Alabama jurisdictions, yes. Permit requirements vary by city and county, but full system replacements typically require a mechanical permit. A licensed contractor will pull the permit. Unlicensed contractors often skip the permit, which exposes you to issues at home sale time and voids most warranties.

Q: Can a national HVAC chain be trusted?

A: Some can, some cannot. The key questions are the same regardless of chain or local: current Alabama license, current insurance, written warranty, reasonable reviews, no commission sales pressure, clear written estimate. National chains sometimes have stronger warranty backing but weaker individual technician accountability. Local owner-operators usually have the opposite tradeoff.

Q: What does "factory authorized dealer" mean?

A: A manufacturer (Trane, Carrier, Goodman, etc.) has reviewed the contractor and authorized them to sell and install that brand under the manufacturer's warranty terms. It usually means the contractor's technicians have received factory training on that brand's equipment and the contractor maintains a minimum installation volume.

Q: Do you serve Auburn, Dadeville, and Lake Martin?

A: Yes. Our Dadeville location at 360 Windflower Dr (334-478-1438) covers Auburn, Dadeville, Tallassee, Eclectic, Blue Ridge, and the Lake Martin area. Montgomery location at 2546 Bell Rd (334-264-6464) covers Montgomery, Pike Road, Prattville, Wetumpka, Millbrook, Coosada, Deatsville, Mathews, Elmore, Tuskegee, and Old Cloverdale.

Q: What questions should I never trust a contractor's answer on?

A: License number (always verify yourself on the HACR Board lookup, do not trust the contractor's claim alone). Insurance coverage (ask for a Certificate of Insurance sent directly from the insurance provider). Warranty terms (get them in writing, not verbally). Pricing (get the quote in writing on company letterhead, with itemization).
