Do You Need a Permit to Replace Your AC in Baldwin County?

Short answer: yes — in almost every case in Baldwin County, replacing your AC requires a permit, and the new system has to pass an inspection before the job is truly finished. A licensed HVAC contractor should pull that permit in their own name, schedule the inspection, and hand you the signed-off paperwork at the end. If somebody offers to swap your system out "cash, no permit, save you money," that is a red flag, not a deal.

Why Baldwin County requires a permit at all

Baldwin County is one of the fastest-growing areas in the 6th-fastest-growing U.S. metro, and Spanish Fort sits right in the middle of that growth. The town has roughly 10,000-11,000 residents, household incomes about 35% above the national median, and a median home that was built around 1999. That last number is the one I think about every day: a huge chunk of the housing stock in Spanish Fort, Daphne, and the rest of the Eastern Shore is now 20-25 years old, which is exactly the window when the original AC system gives up.

When that many systems get replaced in that short a time, the county and the cities care a lot about making sure the new equipment is installed safely. That is what the permit is — a tracked record that a licensed contractor did the work, sized the equipment correctly, ran the electrical to code, and (if it is a gas unit) vented combustion properly. After Hurricane Sally tore through the area in September 2020, code enforcement around roof penetrations, condenser tie-downs, and electrical disconnects got even more attention, because the inspectors saw firsthand what bad installs look like after a storm.

What kind of jobs actually need a permit?

The line is simpler than most homeowners think. If you are doing a full system change-out — new condenser, new air handler or furnace, new line set, new disconnect — that is permitted work in Spanish Fort and across Baldwin County. If you are replacing just the outdoor condenser and matching it to the existing indoor coil, that is still usually permitted, because it is a mechanical replacement that affects the refrigerant circuit and the electrical disconnect.

Things that generally do NOT need a permit:

• Routine maintenance and tune-ups
• Capacitor, contactor, or fan motor replacements
• A standard service repair where no equipment is being changed out

Things that almost ALWAYS need a permit:

• Full AC or heat pump replacement
• Furnace replacement (especially gas)
• Adding a new system to a room addition
• Moving the condenser to a different location on the house
• Adding a mini-split where none existed

If you are not sure where your job falls, ask the contractor before they start. A real licensed company will tell you straight. You can also read more on our AC installation service page, which walks through what a proper change-out looks like start to finish, and our complete 2026 guide to replacing your AC on the Eastern Shore covers how the permit fits into the larger job.

Electric system vs gas system: two different inspections

This is the part most homeowners on the Eastern Shore do not realize. The inspection on a straight electric AC or heat pump is not the same as the inspection on a system with a gas furnace.

For a heat pump or straight-electric setup — which is what most homes around TimberCreek, Stonebridge, Churchill, Blakeley Forest, Blakeley Oaks, The Highlands, The Lakes, Shenandoah, and Spanish Fort Estates are running — the inspection usually covers two things: the mechanical install (pad, refrigerant lines, condensate, equipment matching) and the electrical (disconnect, whip, breaker size, wire gauge, bonding). Our mild winters down here, where it rarely drops below the high 20s, are exactly why heat pumps fit so well on this side of Mobile Bay.

For a gas furnace replacement — common in some of the older Spanish Village, Audubon, and Highway 181 corridor builds — you add a third layer: the gas piping and combustion venting inspection. The inspector is checking gas line sizing, sediment trap, shutoff location, and the flue/venting path. That last one matters because a furnace that does not vent properly can put carbon monoxide back into the house. If your old system was gas and you are staying with gas, expect a longer inspection. If you are switching from gas to a heat pump — which a lot of homeowners on the Eastern Shore are doing — you will need both the old gas line capped to code and the new electrical run sized for the heat pump.

Why a licensed contractor should pull the permit, not you

Yes, in Baldwin County a homeowner can technically pull some permits on their own house. I do not recommend it for a full AC change-out, for three reasons.

First, the permit ties responsibility to whoever pulls it. If a licensed HVAC contractor in Spanish Fort pulls the permit, the inspector is holding that contractor — and their state license (Air Solutions is AL #23194) — accountable for the install passing code. If you pull it yourself, you are the one on the hook, even though the contractor did the actual work.

Second, most major manufacturer warranties require a licensed installer and a permitted install. If your new system needs a warranty claim three years from now after a humid August (Spanish Fort hits about 79% humidity in peak summer), the manufacturer can and will ask for the permit number and installation records.

Third, insurance. After a big storm event like Sally — which knocked out power across the whole county and damaged a lot of equipment from the Causeway and Battleship Parkway all the way up Highway 225 toward Historic Blakeley State Park — homeowners filed AC claims. Carriers that wanted to push back asked for permits and inspection records. Unpermitted work is harder to defend.

What "no permit" actually costs you

I see this pitch a lot, especially from out-of-town installers who set up after a storm: "We can do it for less if we skip the permit." Here is what that really buys you:

• No third-party verification that the system is sized right for your house. A house in The Lakes or near Eastern Shore Centre is built different from a 1990s ranch near Malbis or US-31 — the load is not the same.
• No inspection of the electrical disconnect or breaker — the part most likely to fail in a Gulf Coast lightning storm.
• A problem at resale. Real estate attorneys around the Eastern Shore Centre and Spanish Fort High School area will absolutely flag missing permits during the title search.
• A void warranty when you need it most.

The few hundred dollars "saved" upfront is almost always wiped out the first time something goes wrong. The permit and inspection are a normal line item, not padding — we cover where they land in our breakdown of what AC replacement costs in Baldwin County in 2026.

How the process actually runs at our shop

When we replace a system in Spanish Fort — whether the house is near Stonebridge Elementary, off Hwy 181, in one of the D.R. Horton or Truland builds, or down toward the Causeway and the USS Alabama at Battleship Memorial Park — the order of operations is the same:

1. We size the new system for your specific house, not just match the old tonnage.
2. We pull the mechanical (and electrical, and gas if applicable) permits in our name.
3. We install the equipment, including any required updates to the disconnect, pad, or condensate routing.
4. We schedule the inspection with the authority having jurisdiction.
5. We hand you the signed-off permit card and warranty paperwork.

That is how it is supposed to work. Anything less and you are taking on risk that should be ours.
