How Much Does a New HVAC System Cost in Dothan, AL? (2026 Guide)

Updated September 28, 2026 | Long Heating, Air, and Plumbing, Dothan, AL

Direct Answer

A new HVAC system in Dothan, AL costs about $7,000 to $16,000 installed in 2026. Central AC alone runs $5,000 to $10,000, a heat pump $7,000 to $14,000, and an AC plus gas furnace pair $8,000 to $16,000. System size, SEER2 tier, and ductwork condition decide where a specific home lands.

TL;DR

• Dothan installed range: $7,000 to $16,000 for most homes in 2026
• Heat pumps are the most common fit for the Wiregrass climate; AC plus furnace if you have gas
• Alabama’s legal minimum is 14.3 SEER2 for split AC and heat pumps, not 15.2 as some guides claim
• The federal 25C tax credit expired December 31, 2025; no 2026 install qualifies
• Alabama Power pays $1,000 for a gas-to-heat-pump switch at 18 SEER2 plus, on Alabama Power meters only
• Ductwork and equipment tier move the price more than brand does

One liner: Get the load calculation and the duct scope in writing, and the price will make sense.

Key Numbers

The Quick Answer for Dothan Homeowners

In short: Most Dothan homeowners pay between $7,000 and $16,000 for a new HVAC system installed in 2026, with a heat pump or AC plus furnace replacement in a typical 1,800 to 2,400 sq ft home landing near $10,000 to $13,000. Ductwork, efficiency tier, and system size move it from there.

A new HVAC system in Dothan, AL costs about $7,000 to $16,000 installed in 2026. Central AC alone runs less, a full heat pump or AC plus gas furnace replacement runs more, and homes that need new ductwork sit at the top of the range. The 2025 refrigerant switch added a modest premium that is now built into every quote. [1][3]

That range sits a little above what a quick national search returns. Nationally, homeowners spent anywhere from $5,000 to $28,000 for a full replacement this year, with a basic AC and furnace job in a 2,000 sq ft home landing between $7,000 and $20,000. [1] Recent project data puts the midpoint for a 2,000 to 2,500 sq ft home near $13,430 before add-ons. [2]

Dothan pushes toward the upper half of that spread for three reasons. The cooling season runs close to six months, so equipment works harder and a bargain unit that is slightly undersized fails sooner. Humidity means the system has to pull moisture out of the air, not only cool it, which favors properly sized equipment over cheap capacity. And most homes across the Wiregrass, from Enterprise and Headland to Ozark, Daleville, Ashford, and Abbeville, run their ducts through unconditioned attics that hit well over 120 degrees in July. Leaky attic ducts can turn a fair equipment price into a disappointing system, which is why a good quote for HVAC installation in Dothan addresses the ducts, not only the box outside.

One more thing to check before comparing numbers: an installed price should cover the equipment, labor, refrigerant charge, permit, and haul-away of the old unit. If a quote leaves any of those out, add them back before you compare it to the table below.

New HVAC System Cost by Type in Dothan, AL

In short: Central AC alone runs about $5,000 to $10,000 installed in Dothan, a heat pump $7,000 to $14,000, and an AC plus gas furnace pair $8,000 to $16,000. Ductless systems price per zone, and packaged units sit between AC-only and a full split system.

The table below gives installed ranges for the Dothan market in 2026. Each figure covers equipment, labor, refrigerant, permit, and disposal of the old unit. Ductwork replacement is not included and is covered in the next section.

A rougher rule is $3 to $6 per square foot installed, which puts a 2,000 sq ft Dothan home at $6,000 to $12,000 before ductwork. Use it as a sanity check, not a quote. [16]

Nationally, a new central AC installed runs about $4,500 to $9,500, with a 3 ton system near $4,800 to $8,000. [4] Heat pump installs commonly fall between $6,000 and $12,000, and ductless runs $3,000 to $6,000 per zone. [5] Furnace installs range from $3,800 to $12,000 depending on fuel and efficiency. [17] Dothan ranges sit a step above those because of the labor and duct issues described in the first section, and because labor alone is usually 30 to 50 percent of the total. [5]

Why the heat pump row matters here. Dothan winters are mild, so a heat pump handles heating without the strip-heat penalty northern homes pay. One piece of equipment does both jobs, which is why heat pump installation in Dothan is the most common replacement across the Wiregrass. A gas furnace still makes sense if you have gas service and want the fastest heat on a cold January morning.

The packaged-unit trap. Plenty of 1980s and 1990s slab homes in Headland, Daleville, and south Dothan have a packaged unit sitting on a pad beside the house. Replacing it like-for-like is simple. Converting to a split system means adding an air handler indoors and new refrigerant lines, and that conversion can add $2,000 to $4,000 to the job. Ask which one your quote assumes.

Size steps the price. Each ton of capacity adds roughly $700 to $1,200 to the installed cost on the same product line. A 2 ton unit for a small home and a 5 ton unit for a large one can be several thousand dollars apart on identical efficiency. Size comes from a Manual J load calculation, not square footage alone, and the next section explains why that matters more in Dothan than in most places.

What Moves the Price Up or Down

In short: Six things explain most of the gap between two quotes for the same Dothan home: system size, SEER2 tier, refrigerant, ductwork and electrical, equipment tier, and the labor and permit side of the job. Ductwork and equipment tier swing the number the most.

Size and tonnage

Capacity is priced per ton, and the right tonnage comes from a Manual J load calculation that accounts for your windows, insulation, orientation, and duct location. Bigger is not safer here. In Dothan’s humidity, an oversized unit cools the air fast, shuts off before it pulls moisture out, and leaves the house cold and clammy. A 5 ton unit on a 1,600 sq ft home is a common mistake, and it costs more up front and more every month. Ask for the load calculation, not a square-footage guess.

SEER2 efficiency tier

Every step up in SEER2 costs money at install and returns some of it on the power bill. Moving from a baseline system to SEER2 16 to 17 typically adds $1,000 to $2,500, and premium SEER2 18-plus variable-speed systems can add $3,000 or more. [4] With a six-month cooling season, the middle tier usually pays back in Dothan. The top tier is a comfort purchase as much as an efficiency one. The next section covers what Alabama actually requires as a minimum, which is lower than some guides claim.

Refrigerant

Since January 1, 2025, manufacturers can no longer build new residential equipment on R-410A. New systems ship with R-454B or R-32, at equipment prices roughly 8 to 10 percent higher than the outgoing generation. [3] That premium is already inside every 2026 quote, so you will not see it as a line item. The 2025 shortage that pushed cylinder prices up is over, so a contractor who still cites it as a reason for a big markup is working from old news. [3]

Ductwork and electrical

This is the line item that surprises people. Ducts are a separate system from the equipment, and a new $12,000 heat pump attached to leaky, undersized attic ducts will never perform as rated. A full duct system replacement runs around $4,300 in 2026, and homes that need new ducts can see the total rise by $3,000 or more. [6][1] Picture two identical Dothan ranch homes with the same 3 ton heat pump. One has sealed, insulated ducts. The other loses a quarter of its air into a 130 degree attic. The second homeowner paid the same for equipment and gets a system that runs longer, costs more to operate, and wears out sooner. A duct inspection before the quote tells you which house you own.

Electrical work is the other hidden line. A heat pump replacing a gas furnace may need a new 240 volt circuit, and an older panel that is already full may need an upgrade, commonly $500 to $2,500 depending on capacity. [1] Ask the estimator to check the panel during the visit.

Brand and equipment tier

Within one brand, a single-stage, two-stage, and variable-speed model of the same tonnage can be thousands apart. Variable-speed compressors run longer at low speed, which pulls more humidity out of the air, the feature Dothan homes benefit from most. Brand matters less than the tier and the installer. A mid-tier unit installed well outperforms a premium unit installed poorly.

Permits, labor, and access

Labor is 30 to 50 percent of the total. [5] A Houston County or City of Dothan mechanical permit commonly runs $250 to $400 and should appear on the quote. [7] Skilled technicians remain in short supply across the industry, and emergency installs in July carry a premium for that reason, which is one more argument for scheduling in spring or fall. [1] Access adds hours: an air handler in a tight attic or crawlspace takes longer than one in a hallway closet, and a crane for a rooftop packaged unit adds its own fee. Professional HVAC installation should itemize these rather than fold them into a round number.

Alabama’s Efficiency Rules and What They Mean for Your Quote

In short: Alabama sits in the Department of Energy’s Southeast region, where the minimum for a new split-system air conditioner under 45,000 BTU is 14.3 SEER2, and split heat pumps must meet 14.3 SEER2 and 7.5 HSPF2. Some cost guides claim 15.2 SEER2 is the floor. It is not, and the difference is a price tier on your quote.

The federal efficiency rules changed on January 1, 2023, and they are set by region. The Department of Energy puts Alabama in the Southeast region along with Florida, Georgia, Mississippi, and the rest of the Gulf and southern Atlantic states. [8] Here is what a new installation in Dothan has to meet.

Source: U.S. Department of Energy, 2023 residential central AC and heat pump standards. [8]

Where the online guides go wrong. One widely shared 2026 guide states that in the Southeast a contractor “cannot legally sell and install a 14.3 SEER2 split AC system” and that the minimum is 15.2 SEER2. [9] That is incorrect. The DOE’s own standards document lists 14.3 SEER2 for the Southeast on systems under 45,000 BTU/hr, and 15.2 SEER2 appears in the rules only as a threshold in the Southwest region’s EER2 test, which does not apply to Alabama. [8] The same guide lists 8.1 HSPF2 for heat pumps; the federal figure is 7.5. [8]

Why this matters for your money. The step from a minimum-efficiency system to the 16 to 17 SEER2 tier adds $1,000 to $2,500 to an installed price. [4] A homeowner who is told that tier is legally required pays for it without choosing it. That is not the same as saying the minimum is the right buy. For a home that runs the air conditioner from April into October, the middle tier usually earns its premium back on the power bill, and variable-speed heat pump options handle Dothan humidity better than any baseline unit. The point is to choose the tier on purpose, with the real floor in view, rather than have it chosen for you.

How to use this. If a quote lists 14.3 SEER2 or 13.8 SEER2 equipment, it is legal in Alabama. If a contractor says a higher rating is mandatory, ask which rule they are citing. A good installer will explain the trade-off in dollars and comfort instead of leaning on a requirement that does not exist here.

Tax Credits and Rebates: What Changed in 2026

In short: The federal 25C tax credit expired on December 31, 2025, so no system installed in 2026 qualifies. Alabama Power still pays $1,000 for a gas furnace to heat pump switch at 18 SEER2 or higher, but only on its own meters. Confirm your utility before you count on any rebate.

The federal credit is gone. For three years the Section 25C Energy Efficient Home Improvement Credit returned 30 percent of the cost of a qualifying heat pump, up to $2,000, plus up to $600 for a central AC and $500 for a furnace. Congress ended it in the One Big Beautiful Bill Act, signed July 4, 2025, for any equipment placed in service after December 31, 2025. [10] “Placed in service” means installed and running. Signing a contract, paying a deposit, or getting financing approved in 2025 does not count if the system started up in January. [11] If your install finished in 2025, you can still claim it on your 2025 return using Form 5695. [11]

A Dothan homeowner who signed in mid-December 2025 and had the crew out the second week of January 2026 lost that $2,000. It was not the contractor’s fault, but it was a $2,000 surprise, and it is why the credit should not appear anywhere on a 2026 quote. If a proposal still subtracts a “federal tax credit” from the bottom line, ask for a corrected version.

What still exists in 2026

Check the meter before the rebate. Most homes inside Dothan city limits buy power from Dothan Utilities, not Alabama Power. Rural Houston County and parts of the surrounding counties are served by Wiregrass Electric Cooperative. Alabama Power serves some of the region, but not all of it. The Switch and Save rebate only applies on an Alabama Power account, so the first question is which utility name is on your bill. The second is whether you are replacing a gas furnace, since a heat pump replacing an old heat pump does not qualify. If both answers line up, a qualifying heat pump at 18 SEER2 or higher gets the $1,000 back, and the higher tier is often the one Dothan homes benefit from anyway.

For most 2026 buyers, the practical levers are dealer promotions and financing, which the next sections cover.

Repair or Replace: A Dothan Rule of Thumb

In short: Replace when the system is 12 or more years old, the repair costs more than half of a new one, it runs on R-22, or the bills keep climbing while the comfort drops. Repair when the unit is under 10 years old and the fix is a single, inexpensive part.

Four signs that a repair is throwing money at a system that is on its way out:

1. Age. A central AC or heat pump in Dothan runs about six months a year, so 12 to 15 years here is a full life. Past that point, one repair tends to follow another.
2. Repair cost. If the estimate is more than half the price of a comparable new system, replacement usually wins on cost alone.
3. Refrigerant. Any system built before 2010 likely runs on R-22, which is no longer produced and is expensive to source. A leak on an R-22 unit is a replacement conversation, not a recharge.
4. Bills and comfort. Rising summer power bills, rooms that never cool evenly, or a unit that runs without stopping on a 95 degree afternoon point to lost capacity that a part swap will not fix.

A quick math check helps. Multiply the system’s age by the repair quote. If the result is above 5,000, lean toward replacement. A 2012 heat pump in Ozark with a $1,400 compressor quote gives 14 times 1,400, or 19,600. That is well past the line, and that $1,400 is a down payment on a system that will not fail again next July.

The 2026 refrigerant wrinkle. Two things changed this year. Service refrigerant for new systems now averages about $25 per pound for R-454B and $18 for R-32, while R-410A for older systems remains available but is on a declining supply schedule. [3] And under an EPA rule that took effect July 27, 2026, contractors may still install units built before 2025 that use R-410A until existing supplies run out. [13] That means you may be offered a discounted R-410A system as a like-for-like swap. It is legal and it can be a fair deal on price, but you are buying equipment on a refrigerant that gets scarcer every year. Ask what the service cost looks like five years out before you take the discount.

When repair is the right call. A system under 10 years old with a failed capacitor, contactor, or blower motor should be repaired. Those parts are cheap relative to the system, and a unit with a clean maintenance record has plenty of life left. If you are on the fence, a maintenance plan and one honest assessment of when to replace an air conditioner beats guessing in August.

How to Pay for It: Financing and Monthly Cost

In short: Most Dothan homeowners finance a new system rather than paying cash, and a $12,000 install works out to roughly $160 to $255 a month depending on the term. Long offers financing through GoodLeap, and a maintenance membership protects the system once it is in.

A five-figure quote reads differently once it becomes a monthly number. The table below is example math only, at an illustrative 9.99 percent APR, so you can see the shape of it. Actual rates and terms depend on your credit and the promotion running at the time.

Long’s HVAC financing options run through GoodLeap, with an application that takes a few minutes. Promotional terms change through the year, so ask what is available when you get your quote.

Three questions before you sign any financing. First, what is the APR after any promotional period ends? A “no interest for 18 months” offer that jumps to 26 percent can cost more than a plain 10 percent loan if you miss the payoff date. Second, is there a prepayment penalty? You want the freedom to pay it off early. Third, who holds the loan? Knowing whether the lender is GoodLeap, a bank, or the contractor tells you where to call if something goes wrong.

The bill offset is real. A 16 SEER unit replacing a 2010-era 10 SEER unit cuts cooling energy use by up to about 30 percent for the same comfort. [16] On a Dothan summer power bill, that savings covers a meaningful slice of the payment. As an illustration, a family that spreads an $11,500 heat pump over ten years often finds the monthly payment lands close to what they had been spending on repairs plus the drop in their power bill. That is not free, but it is a lot closer to break-even than the sticker price suggests.

Protect what you financed. Long’s Total Comfort Now membership is $129 to enroll and then $8.25 a month, which covers the tune-ups most manufacturers require to keep the parts warranty intact. [14] A ten-year warranty on a system you are still paying for is worth keeping valid.

Plan it, do not rush it. The most expensive way to buy a system is on a 98 degree afternoon in July with the house at 88 inside. Crews are booked, equipment is tight, and there is no time to compare. If your system is showing the replacement signs from the last section, get the quote in the fall or spring and schedule it on your terms.

What a Real Quote Should Show You

In short: A trustworthy HVAC quote lists the load calculation, the exact model numbers with an AHRI matched-system number, the real SEER2 rating, the refrigerant, the duct scope, the permit, and a warranty split between parts and labor. A round number on a business card is not a quote.

Get two or three written quotes and compare them line by line, not by the bottom number. Here is the eight-point check. If a proposal is missing more than two of these, ask for a revised one before you compare prices.

1. A Manual J load report, room by room, with your county’s design conditions. Not a square-footage guess.
2. Model numbers for every piece: outdoor unit, indoor coil or air handler, furnace if included, and thermostat.
3. An AHRI reference number proving the outdoor and indoor pieces were tested together. A mismatched coil can drop the real efficiency below the number on the brochure.
4. SEER2, EER2, and HSPF2 for that matched pair, not a rounded “16 SEER” from the old scale.
5. The refrigerant named: R-454B, R-32, or pre-2025 R-410A inventory, so you know what you are buying and what service will cost.
6. Duct scope in writing: sealed, modified, or replaced, with what that includes.
7. Permit, disposal, electrical, and condensate as line items, plus the pad or stand.
8. Warranty in three parts: manufacturer parts, contractor labor, and compressor, with who registers it and by when.

Here is how that plays out. Two quotes on the same Enterprise-area home can come in $2,000 apart, and the cheaper one is often missing the duct scope, the permit line, and the AHRI number. Once those are added back, it becomes the more expensive of the two. Price differences between quotes usually live in what one of them left out.

The load calculation deserves one more note. Industry sizing guidance calls for the selected equipment to land within about 15 percent of the calculated cooling load. [15] Bigger is not a safety margin. In a humid climate it is a comfort problem you pay for twice, once at install and again on the power bill.

A contractor who already works this way will hand you all eight items without being asked. That is what our installation process includes on every Dothan job, and it is the easiest way to tell a fair price from a cheap one.

Getting an Accurate Number for Your Home

In short: A new HVAC system in Dothan runs $7,000 to $16,000 installed in 2026, and three things decide where your home lands: the load calculation, the efficiency tier you choose, and the condition of your ducts. An online estimate gets you close. A load calculation at your home gets you exact.

Everything above narrows the range. Only a visit closes it. When a technician measures the house, checks the ducts, and runs the load calculation, the number stops being a range and becomes your quote, itemized the way the last section describes.

Have these ready for the estimate. The age of your current system (the data plate on the outdoor unit shows it), a recent summer power bill, the rooms that never cool evenly, and the name of your electric utility so any rebate question gets answered on the spot. If you have a repair quote in hand, bring that too. It changes the math.

Two ways to get your number.

• Get online pricing in a few minutes if you want a fast, honest ballpark before anyone comes out.
• Book an in-home estimate for the full load calculation and an itemized quote. Financing options can be worked into the same visit.

Frequently Asked Questions

How much does a new HVAC system cost in Dothan, AL?

Most Dothan homeowners pay $7,000 to $16,000 for a new HVAC system installed in 2026. Central AC alone runs $5,000 to $10,000, a heat pump $7,000 to $14,000, and an AC plus gas furnace pair $8,000 to $16,000. Ductwork, system size, and SEER2 tier decide where a specific home lands. [1]

How much does a new AC unit cost in Alabama?

A new central air conditioner installed runs about $5,000 to $10,000 in the Dothan area, keeping your existing furnace or air handler. Nationally the typical job lands near $6,500, and a 3 ton unit runs $4,800 to $8,000 before local labor and duct work. [4]

What does a heat pump replacement cost in Dothan?

A heat pump replacement in Dothan runs about $7,000 to $14,000 installed. Variable-speed models and electrical upgrades push it toward the top. Heat pumps are the most common fit for the Wiregrass climate because one unit handles both heating and cooling. [5]

How much does a 3 ton HVAC system cost installed?

A 3 ton central AC runs about $4,800 to $8,000 installed nationally and a step above that in Dothan. A 3 ton heat pump or AC plus furnace system lands closer to $8,000 to $12,000. Each added ton adds roughly $700 to $1,200 on the same product line. [4]

Is it cheaper to replace the AC and furnace together?

Usually yes. Replacing both in one visit shares the labor, permit, and disposal costs, and a matched system carries one warranty. Replacing them a few years apart often costs $1,500 to $3,000 more in total and can leave a mismatched coil that lowers efficiency. [5]

What SEER2 rating is required in Alabama?

Alabama is in the Department of Energy’s Southeast region. The minimum for a split-system air conditioner under 45,000 BTU is 14.3 SEER2, and split heat pumps must meet 14.3 SEER2 and 7.5 HSPF2. Some guides claim 15.2 SEER2 is the floor. It is not. [8]

Is there still a federal tax credit for a new HVAC system in 2026?

No. The Section 25C Energy Efficient Home Improvement Credit expired on December 31, 2025. Equipment placed in service in 2026 does not qualify, even if the contract was signed in 2025. Installs completed in 2025 can still be claimed on a 2025 return. [10]

Are there any HVAC rebates in Dothan?

Alabama Power pays $1,000 when a gas furnace is replaced with an 18 SEER2 or higher heat pump, on Alabama Power accounts only. Many Dothan homes are served by Dothan Utilities or Wiregrass Electric Cooperative instead, so check the name on your bill before counting on a rebate. [12]

Why did HVAC prices go up in 2025 and 2026?

Manufacturers stopped building R-410A systems on January 1, 2025, and new equipment on R-454B or R-32 costs roughly 8 to 10 percent more. Labor shortages and higher efficiency minimums added to it. The 2025 refrigerant shortage that spiked prices has since eased. [3]

Should I repair or replace a 12 year old heat pump?

Lean toward replacement. Twelve years is a full life in a six-month cooling climate, and multiplying the age by a repair quote usually lands above 5,000, the common threshold. Repair makes sense only if the fix is a single inexpensive part like a capacitor. [6]

What should be included in an HVAC quote?

A Manual J load calculation, model numbers for every piece, an AHRI matched-system number, the real SEER2 and HSPF2 ratings, the refrigerant type, the ductwork scope, permit and disposal line items, and a warranty split into parts, labor, and compressor. [15]

Does Long offer financing for a new HVAC system?

Yes. Long Heating, Air, and Plumbing offers financing through GoodLeap. A $12,000 system works out to roughly $160 to $255 a month depending on the term and rate. Ask what promotional terms are running when you get your quote. [14]

How much does an HVAC estimate cost?

Many contractors offer free in-home estimates. Some charge $50 to $200 and apply it to the job if you move forward. Ask before scheduling, and ask whether the visit includes a load calculation. [17]

What is the difference between SEER and SEER2?

SEER2 is the test standard used since 2023. It runs the equipment against higher duct pressure, so the same unit scores about 5 to 7 percent lower on SEER2 than on the old SEER scale. A 15 SEER unit is roughly 14.3 SEER2. Compare quotes on the same scale only. [16]
