Start with the license
Every HVAC contractor working in Alabama should hold an active license from the Alabama Board of Heating, Air Conditioning and Refrigeration Contractors (HACR). Active licensees are required to carry a $20,000 performance bond, which gives you some financial protection if a job goes badly.
Ask for the contractor's HACR license number directly and don't be shy about it; a legitimate contractor will provide it without hesitation. You can also check license status through the HACR board's site.
If you're inside Madison city limits, the contractor also needs a City of Madison business license and must list their HACR license number on the mechanical permit application.
Get multiple written bids
Get at least two or three bids for any full system replacement, and make sure each one is based on an actual load calculation for your home rather than just quoting the same tonnage as your old system.
A detailed bid should specify the equipment brand and model, SEER2 rating, warranty terms (both parts and labor), permit responsibility, and whether ductwork modifications are included.
Be wary of a bid that's dramatically lower than the others; it may mean lower-grade equipment, no permit filed, or corners cut on installation quality that could show up later as comfort or efficiency problems.
Confirm permits and rebate eligibility upfront
Ask directly whether the contractor will pull the required mechanical permit for your address, whether that's through the City of Madison or the applicable county office, and confirm this is included in the quoted price.
If you're hoping to claim a TVA EnergyRight rebate, ask whether the contractor is enrolled in the Quality Contractor Network, since only enrolled contractors' installs qualify for those rebates.
A contractor who tries to talk you out of pulling a permit is a red flag; skipping it can cause problems with your homeowner's insurance or when you eventually sell the house.
Red flags to watch for in a fast-growing market
Madison's rapid growth has attracted both established local companies and newer or out-of-town crews chasing subdivision volume. Be cautious of door-to-door sales pressure, demands for full payment upfront, or contractors who can't provide local references.
Check for a physical business address and how long the company has operated in the Huntsville metro; a contractor with a track record in the area is generally a safer bet than one that just started soliciting new subdivisions.
Verify insurance (general liability and workers' comp) in addition to the HACR license, since license status alone doesn't guarantee proper coverage for accidents or property damage during the job.
Comparing quotes on price alone isn't enough
Two bids for the 'same' 3-ton heat pump can vary by thousands of dollars depending on equipment tier, ductwork work included, and warranty length, so compare the full scope, not just the bottom-line number.
See our AC repair cost guide and HVAC replacement cost guide for typical price ranges in this metro so you can spot a bid that's out of line.

Common questions
What license should an HVAC contractor in Madison, AL have?
They should hold an active HVAC contractor license from the Alabama Board of Heating, Air Conditioning and Refrigeration Contractors, plus a City of Madison business license if working inside city limits.
How many quotes should I get for an HVAC replacement?
Most homeowners should get at least two or three written bids, comparing equipment specs, warranty terms, and whether permits are included, not just the total price.
Should I be worried about door-to-door HVAC sales in Madison?
Be cautious. Madison's growth has attracted a mix of established and newer companies; verify licensing and local references before signing anything from a door-to-door pitch.
Does the contractor need to pull a permit for my replacement?
Yes, in almost all cases a mechanical permit is required for a full system replacement, and your contractor should include pulling it as part of the job.
How do I check if a contractor is in TVA's Quality Contractor Network?
Ask the contractor directly, or use the 'find a contractor' search tool on the EnergyRight website, which lists Quality Contractor Network members.
What's a red flag when getting HVAC bids in Madison?
A bid dramatically lower than others, pressure to pay in full upfront, no mention of permits, or an inability to provide a HACR license number are all red flags worth pausing over.
