How Much Does It Cost to Replace an AC System in Dallas?

Last updated: May 22, 2026

By the HVAC Pricing Guide Team

AC replacement in Dallas costs $4,800 to $13,000 installed in 2026, with most 2,000 square foot homes landing between $7,200 and $10,500 for a complete 3-ton to 3.5-ton system. Dallas pricing sits near the national average, with peak demand from June through September adding 8 to 15% to lead times and contractor pricing. The 2025 refrigerant transition from R-410A to R-454B and the SEER2 efficiency standard have pushed Dallas equipment quotes up roughly $800 to $1,500 compared to 2023 baselines, before installation labor.

What a Dallas AC Replacement Costs in 2026

The price you pay for AC replacement in Dallas depends on five variables that contractors price independently: system tonnage, SEER2 efficiency tier, refrigerant type, the brand and warranty package, and the labor required to integrate the new equipment with your existing ductwork, electrical service, and refrigerant lineset. A 2,000 square foot single-story Dallas home running on a single-zone central system typically needs a 3-ton to 3.5-ton condenser paired with a matched evaporator coil and either an air handler or a gas furnace blower. Quoted prices for that configuration cluster between $6,200 and $11,500 installed in 2026.

The Dallas market sits inside the U.S. Department of Energy's Southern climate region, which carries different SEER2 minimum efficiency standards than the North. Since January 2023, new split-system air conditioners installed in Texas must meet at least 14.3 SEER2 for units under 45,000 BTU per hour, with 15.2 SEER2 required at 45,000 BTU and above. The previous SEER 14 floor that ran through 2022 is no longer a current option. Any Dallas contractor quoting "SEER 14" equipment in 2026 is either citing the old metric incorrectly or trying to sell legacy stock that no longer ships from the manufacturer.

For a deeper national pricing baseline, see our AC installation cost guide, which breaks down labor, equipment, and ancillary cost ranges across regions. For Dallas-specific pricing across the entire HVAC scope including repair and tune-ups, our Dallas HVAC cost guide covers the full market. If you already know you need a 3-ton system, the 3-ton HVAC replacement cost guide isolates that size class with national averages.

The AC Replacement Options Dallas Contractors Quote

When a Dallas contractor builds your replacement quote, they are choosing equipment from a tiered catalog and labor scope from a tiered installation playbook. Understanding the layers makes the spread between three competing quotes much easier to read.

Equipment efficiency tiers, by what Dallas installers actually carry:

• Baseline (14.3-15.2 SEER2): single-stage condenser, single-speed blower. Brands include Goodman GSXN, Rheem Classic, Lennox ML series, Carrier Comfort. Installed for a 3-ton system: $5,800 to $7,800. The right choice for a rental, a flip, or a homeowner who plans to sell within 5 years.
• Mid-tier (15.5-17 SEER2): two-stage condenser, variable-speed indoor blower. Brands include Trane XL16i, Carrier Performance, Lennox EL series, Rheem Prestige. Installed for a 3-ton system: $7,500 to $9,800. The Dallas mainstream; balances efficiency, comfort, and price for a homeowner staying 7 to 12 years.
• High-efficiency (17+ SEER2, variable-capacity): inverter-driven variable-capacity compressor, fully variable indoor blower. Brands include Trane XV20i, Carrier Infinity 26, Lennox SL series, Daikin Fit. Installed for a 3-ton system: $10,000 to $12,800. The right call for Dallas humidity if you spend more than 200 hours a year in the home and dehumidification matters.

The high-efficiency tier ramps capacity up and down rather than cycling on and off, which is the mechanism behind the comfort difference. In Dallas, where dewpoints climb into the low 70s for most of July and August, variable-capacity equipment can run longer at lower output and pull more moisture from the air than a single-stage system that satisfies the thermostat and shuts off.

System configuration choices that affect your quote:

• AC-only replacement vs full system swap: if your gas furnace is healthy and under 12 years old, you can replace the condenser and evaporator coil and keep the existing furnace blower. This saves $2,000 to $3,500 vs a full furnace and air handler change. The catch: AHRI requires the indoor coil to be a matched pair with the new condenser for the rated SEER2 to apply.
• Heat pump conversion: swapping a gas furnace and AC for a heat pump system adds $1,500 to $3,500 to a comparable AC-only replacement but removes the gas bill in winter. With Atmos Energy gas rates in Dallas running 95 cents to $1.25 per CCF in 2026, the payback math depends heavily on the electricity rate plan you pick. See our heat pump vs central AC comparison for the breakdown, and our heat pump replacement cost guide for installed pricing.
• Adding zoning or a smart thermostat: a single new ecobee or Honeywell T9 thermostat installed during the AC change adds $150 to $400. Adding a 2-zone or 3-zone damper system runs $2,500 to $5,500 and only makes sense in homes with persistent room-to-room temperature complaints.

How Dallas-Specific Factors Push Your Replacement Price

Pricing variance across three competing Dallas quotes on the same home rarely comes from contractor markup. It comes from how each contractor scopes the things the equipment touches: ductwork, electrical, refrigerant lines, and the slab or attic platform the new units sit on.

Ductwork condition. Older Dallas homes built before 1985, particularly in Lakewood, the M Streets, Bishop Arts, Oak Cliff, and University Park, often have undersized or leaky duct trunks. A new 16 SEER2 condenser cannot deliver rated efficiency through ducts that lose 25% of the airflow to attic leakage. Many Dallas replacements include $800 to $2,500 in duct sealing, mastic work, or partial replacement. A full attic duct replacement on a 2,000 square foot home runs $3,500 to $7,000 and is documented in our HVAC duct replacement cost guide.

Electrical service. Dallas homes built before 1970 sometimes still run on a 100-amp service panel that is at capacity. A new high-efficiency variable-capacity condenser pulls less locked-rotor amperage than a 1990s single-stage unit, so most upgrades do not require panel work. But if the existing disconnect, whip, or breaker is undersized or aluminum-wired, expect $250 to $850 in electrical scope. A panel upgrade, if needed, runs $1,800 to $3,800.

Refrigerant line set reuse vs replacement. The 2025 transition from R-410A to R-454B refrigerant means that line sets contaminated with R-410A residue can foul a new R-454B system if not properly flushed and pressure tested. Dallas contractors handle this three ways: reuse with nitrogen flush ($0 to $200), replace the line set in attic runs ($400 to $1,200), or convert to a R-32 system that does not have the cross-contamination issue ($0 incremental). Ask which approach your contractor is using and why.

Permit and inspection fees. The City of Dallas Building Inspection Division requires a mechanical permit for any AC replacement that involves the refrigerant circuit, which is essentially all replacements. Permit fees run $80 to $185 depending on system size and whether electrical work is included. Reputable contractors itemize the permit on your quote. Quotes that skip the permit line are either pricing the work for cash without filing, which voids your manufacturer warranty, or rolling the cost into labor.

Concrete pad, hurricane straps, and slab condition. Dallas does not require hurricane tie-downs, but the city does require a level pad at least 3 inches above grade with proper drainage away from the foundation. Replacing a cracked or sunken pad adds $150 to $400. Some North Dallas neighborhoods with expansive clay soil and shifting foundations need engineered pads; this is uncommon but adds $400 to $900 when required.

Sizing Your Dallas AC: What Fits a 2,000 Square Foot Home

The most common AC sizing question in Dallas is what tonnage a 2,000 square foot home needs. The short answer for the Dallas climate is a 3-ton to 3.5-ton system, but the right answer comes from an ACCA Manual J load calculation, not a rule of thumb. Any Dallas contractor who tells you "we always put a 3.5-ton in a 2,000 square foot house" without measuring is guessing.

The rule of thumb in Dallas is roughly 600 square feet per ton of cooling capacity, which puts a 2,000 square foot home at 3.33 tons. Contractors round to the nearest half-ton, so the choice is 3 ton or 3.5 ton. The deciding factors:

• Insulation level. A 2010+ Dallas build with R-38 attic insulation, double-pane windows, and tight envelope sealing typically rides on a 3-ton system. A 1965 Dallas home with R-19 attic, single-pane windows, and original duct envelope typically needs a 3.5-ton.
• Window orientation and shade. West-facing windows in Dallas absorb afternoon sun load that east-facing windows do not. A home with extensive west glazing and no shade trees needs more capacity than one with mature pecans or oaks on the south and west sides.
• Ceiling height. A 2,000 square foot home with 8-foot ceilings has 16,000 cubic feet of conditioned air. The same footprint with 10-foot vaulted ceilings has 22,000 cubic feet. The volume difference shifts sizing by half a ton.
• Occupancy and gain load. Internal heat gain from people, cooking, electronics, and lighting adds load that Manual J accounts for. A family of five with a home office and a gaming PC generates more sensible load than a retired couple.

Oversizing is the single most common Dallas sizing error. A 4-ton unit on a 2,000 square foot home cools the air to setpoint fast, then shuts off before it has pulled enough humidity out. The result is a 72 degree clammy house in August. Undersizing is rarer; a 2.5-ton unit on a 2,000 square foot Dallas home simply cannot keep up on a 105 degree afternoon and runs continuously without reaching setpoint. Demand a written Manual J calculation as part of any Dallas replacement quote. Contractors who refuse to provide one are sizing by square footage alone.

The R-410A to R-454B Refrigerant Transition and Your 2026 Quote

The EPA's American Innovation and Manufacturing Act phased out R-410A refrigerant production for new equipment as of January 1, 2025. New residential AC systems manufactured after that date use either R-454B (Carrier, Trane, Lennox, Rheem) or R-32 (Daikin, Goodman, Mitsubishi). The transition has three effects on your Dallas 2026 replacement quote.

Equipment cost is up roughly $400 to $900 per system compared to the R-410A baseline because R-454B is a mildly flammable A2L refrigerant that requires updated leak detection, larger refrigerant lineset gauges in some configurations, and revised installation procedures. Manufacturers have priced in the engineering and tooling change.

Installation labor is up $150 to $400 because A2L refrigerants require additional steps: leak detection sensors in the air handler, restricted indoor refrigerant charge limits per ASHRAE 15, and updated brazing procedures. Dallas contractors with EPA 608 Universal certifications and updated A2L training carry the certifications proudly because the retraining cost has been real.

Repairing existing R-410A systems is getting more expensive in Dallas. Wholesale R-410A pricing in early 2026 ranges from $180 to $260 per pound for technicians, up from $40 to $80 per pound in 2022. A 3-ton R-410A condenser holds 7 to 10 pounds of refrigerant. A full recharge after a major leak now costs $1,400 to $2,600 in materials alone, which shifts the repair-vs-replace calculus toward replacement for older systems.

If you are quoted an R-410A "new" condenser in 2026, ask hard questions. Manufacturers can still sell R-410A new-in-box equipment from existing stock through 2025 and into 2026, but new installations using R-410A face shorter parts and refrigerant support windows. Most Dallas contractors stopped quoting R-410A new systems by Q2 2025.

Repair vs Replace: The $5,000 Rule and How Dallas Homeowners Decide

The single most-cited HVAC decision framework is the $5,000 rule. The formula: multiply the age of your current AC in years by the cost of the proposed repair. If the product is over $5,000, replace. If it is under $5,000, repair.

Example: a 12-year-old Dallas AC with a $600 compressor capacitor and contactor repair scores 12 x $600 = $7,200, which is over $5,000. Replace. Same repair on a 4-year-old unit scores 4 x $600 = $2,400, under $5,000. Repair.

The $5,000 rule is a rough heuristic that misses three Dallas-specific considerations:

• Refrigerant type. A 2018 R-410A system at year 8 with a leaking evaporator coil might score 8 x $1,400 = $11,200 under the $5,000 rule, suggesting replacement. But that 2018 system is still 7 to 10 years from end of life. If you repair, you keep R-410A coverage at current prices. The decision is closer than the formula suggests.
• Peak season repair availability. A Dallas AC failure in late July has a $2,500 effective premium even on small repairs: 5-day wait for parts, $300 emergency dispatch, and a hot house in 102 degree weather. The $5,000 rule does not capture this, but it changes real-world decisions.
• Tax credit availability. The federal Section 25C tax credit on heat pump systems expired December 31, 2025. Replacement decisions made in 2024 carried a different math than identical decisions made in 2026.

The 20% rule offers a second test that some Dallas homeowners use alongside the $5,000 rule: if a proposed repair exceeds 20% of a comparable new system's installed price, replace. A $2,200 evaporator coil repair on a system that would cost $9,500 to replace scores 23%, which clears the threshold. A $1,400 fan motor and capacitor repair scores 14%, which does not.

Dallas Neighborhood Patterns: What to Expect by Area

Dallas AC replacement quotes vary by neighborhood not because contractors charge different rates by ZIP code, but because the housing stock dictates what a complete replacement actually requires.

Lakewood, the M Streets, Bishop Arts, and Oak Cliff contain Dallas's oldest single-family stock, much of it built between 1920 and 1955. Original ductwork is often 8-inch round flex retrofitted into attic spaces with no plenum design. Electrical service is frequently 100-amp with original fuse panels. Replacement quotes here run $1,500 to $3,500 higher than comparable square footage in newer neighborhoods because of ductwork, electrical, and condenser placement work. Plan for $9,500 to $13,500 on a 3-ton replacement.

Preston Hollow, University Park, and Highland Park homes range from 1940s teardowns to 2010s rebuilds. Replacement scope depends entirely on the build year. A 1990 University Park home with original ductwork carries similar scope to Lakewood. A 2015 rebuild carries minimal scope beyond the equipment itself.

Far North Dallas, Plano, Frisco, McKinney, and Allen homes built 1995 through present have proper supply and return trunks, dedicated AC circuits, and matched-pair indoor coil platforms designed for clean replacement. Quotes here run $5,500 to $9,500 for a 3-ton replacement; the work is essentially equipment-in, equipment-out.

South Dallas, Pleasant Grove, and South Oak Cliff housing stock includes both 1950s ranch homes and newer infill construction. Quotes vary widely by parcel. Older homes here often have undersized service entrances and original electrical that requires updating during replacement.

East Dallas, Casa Linda, and Forest Hills mid-century homes share characteristics with Lakewood: tight attic spaces, original ductwork, and condenser pads installed close to the property line, which can trigger setback issues with newer larger condensers.

If you are getting quotes in any older Dallas neighborhood, ask specifically whether the quote includes new line set, new electrical disconnect, new condenser pad, and new thermostat. The Far North Dallas quote that excludes these items may be honestly priced for a clean swap. The Lakewood quote that excludes them is missing work that will surface as a change order.

Texas Electricity Rates, SEER2, and Your Dallas Payback Math

Texas operates a deregulated retail electricity market, which means Dallas homeowners choose their retail electric provider while Oncor handles the physical delivery infrastructure. The choice matters for AC replacement payback math because the kilowatt-hour rate you pay determines how fast a higher-efficiency unit recoups its premium.

Average Dallas residential electricity rates in 2026 run 14 to 17 cents per kWh on fixed-rate plans, with time-of-use plans pushing peak afternoon rates to 22 to 28 cents per kWh between 2 PM and 7 PM in summer. A 3-ton Dallas AC runs roughly 2,400 to 3,200 hours per cooling season. The kWh consumption difference between a 14.3 SEER2 baseline unit and a 17 SEER2 mid-tier unit on the same home is approximately 600 to 950 kWh per season, which translates to $90 to $160 per year in pure electricity savings on a flat-rate plan.

The premium for stepping from baseline to mid-tier is roughly $1,700 to $2,800 in Dallas. The simple payback on the efficiency premium alone is 11 to 18 years. The high-efficiency tier (17+ SEER2 variable-capacity) carries a $4,500 to $7,000 premium over baseline and produces $200 to $350 per year in flat-rate electricity savings, for a 15 to 25 year simple payback. The comfort and dehumidification benefits drive the high-efficiency purchase decision in Dallas, not the energy-cost payback.

Oncor occasionally runs efficiency rebate programs for ENERGY STAR-certified high-efficiency equipment. As of mid-2026, Oncor's Take A Load Off Texas program offers $300 to $800 for qualifying AC replacements meeting tiered SEER2 thresholds. Rebates change quarterly; verify current offers at oncor.com before signing your replacement contract. Federal Section 25C tax credits for AC equipment expired December 31, 2025; do not let a contractor quote you a 2026 system with a 25C credit they cannot actually deliver.

Does an AC Replacement Increase Your Dallas Home's Value?

An AC replacement returns roughly 30 to 50 cents on the dollar at sale in the Dallas market, with the recovery rate higher on homes selling above $500,000 and lower on entry-level homes. The recovery is highest when the replacement was recent (within 5 years), included a transferable manufacturer warranty, and used a brand the buyer's inspector recognizes.

A more practical framing in Dallas: an aged or failing AC is a price reduction at sale, not a value-add. A 16-year-old AC on a $650,000 Dallas listing typically draws a $7,000 to $10,000 inspection concession or causes the deal to fall through. A 3-year-old AC on the same listing draws no concession. The replacement is closer to insurance against a deal-breaker than an investment with returns.

If you are selling within 18 months, replace only if the existing system is failing or near failure. Buyers do not pay a premium for a brand-new high-efficiency variable-capacity system; they pay the difference between "AC needs replacement" and "AC is fine." If you are staying 5+ years, the home value question is the wrong frame; the comfort, reliability, and operating cost questions matter more.

How to Find a TDLR-Licensed AC Contractor in Dallas

Texas requires HVAC contractors to hold a Texas Department of Licensing and Regulation (TDLR) Air Conditioning and Refrigeration Contractor license. The license has three classes: Class A handles unlimited capacity, Class B handles units 25 tons or smaller, and apprentice and technician licenses cover field workers. For residential replacement, your contractor must hold a Class A or Class B license, and any technician on site must hold at minimum an apprentice card. Verify any Dallas contractor at tdlr.texas.gov using the License Search tool.

Beyond the state license, the credentials that matter in Dallas:

• EPA 608 Universal certification for any technician handling refrigerant. R-454B and R-32 require updated training; ask for proof.
• NATE certification (North American Technician Excellence). Not required, but a NATE-certified Dallas installer signals a higher quality bar.
• ACCA Manual J training for whoever sizes your system. This is the load-calculation methodology covered earlier; ask which staff member runs your Manual J and what software they use.
• Bonding. TDLR requires contractors to carry a $50,000 surety bond. Ask for the bond certificate number, not just a verbal claim of coverage.
• Manufacturer dealer status. Carrier Factory Authorized Dealer, Trane Comfort Specialist, Lennox Premier Dealer, and Rheem Pro Partner programs carry tighter installation standards and extended warranty access. The status matters more for warranty claims down the road than at purchase.

Pricing transparency questions to ask each Dallas contractor: Does the quote include a written Manual J load calculation? Does the quote itemize the city permit fee and AHRI matched-pair certificate? Does the quote specify R-454B or R-32 refrigerant? What is the labor warranty term, and is it backed by the contractor or by a third-party administrator? What happens if my evaporator coil fails in year 6 under the 10-year parts warranty; do I pay for the labor to swap it?

Red flags in Dallas: same-day pressure tactics, no written Manual J, refusal to itemize the permit, quotes that omit the AHRI matched-pair certificate number, and any contractor whose price drops $2,000 when you mention a competing quote. Honest pricing does not have $2,000 of buffer baked into the first number.

Dallas AC Replacement FAQ

What is the $5000 rule for HVAC?

The $5,000 rule says: multiply your AC system's age in years by the cost of the proposed repair. If the result is over $5,000, replace the system. If it is under $5,000, repair it. A 10-year-old Dallas AC with a $600 capacitor and contactor repair scores 10 x $600 = $6,000, which clears the threshold and suggests replacement. The rule is a useful starting point but does not account for refrigerant transition timing, peak-season repair premiums, or tax credit windows, all of which can swing the actual decision.

How much does an air conditioner cost for a 2000 sq ft home in Texas?

A complete AC replacement for a 2,000 square foot Texas home runs $6,200 to $11,500 installed in 2026 for a 3-ton to 3.5-ton system, with most quotes landing between $7,500 and $9,800 for mid-tier 15.5 to 17 SEER2 equipment. Dallas, Austin, Houston, and San Antonio all sit within $500 of each other on equivalent equipment and scope. The spread inside that range comes from SEER2 tier, brand, ductwork condition, and electrical scope.

How much does a new AC unit cost for 2000 sq ft?

A new AC unit (condenser plus matched evaporator coil) for a 2,000 square foot home costs $4,800 to $9,200 for equipment alone in 2026, with full installed pricing running $6,200 to $11,500 once labor, line set, electrical, permits, and thermostat are included. The condenser by itself accounts for roughly 35 to 45% of the installed price; labor and ancillary work account for the rest. Do not let a Dallas contractor quote you condenser-only pricing as if it were a complete replacement.

What is the 20 rule for HVAC?

The 20 rule has two common interpretations in HVAC. The temperature-differential 20 rule says a properly running AC should produce supply air 15 to 20 degrees cooler than return air at the air handler; a delta-T below 16 degrees suggests low refrigerant, dirty coil, or blower issues. The 20% replacement rule says a repair quote exceeding 20% of comparable new-system installed cost should trigger a replacement conversation. A $2,200 repair on a system that would cost $9,500 to replace scores 23%, which clears the threshold.

How long does AC replacement take in Dallas?

A standard Dallas AC replacement takes one full working day, roughly 6 to 9 hours from arrival to system startup. A full system swap with new furnace, evaporator coil, condenser, and thermostat runs 8 to 12 hours and may stretch into a second day. Ductwork modifications, electrical panel work, or attic platform changes add a day. Schedule replacement in March, April, October, or November when Dallas contractors have open calendars and can give the work proper attention.

Do I need a permit to replace my AC in Dallas?

Yes. The City of Dallas Building Inspection Division requires a mechanical permit for any AC replacement that involves the refrigerant circuit, which covers essentially all condenser and coil changes. The permit fee runs $80 to $185 and is pulled by the contractor, not by the homeowner. Reputable Dallas contractors itemize the permit on the written quote. A quote without a permit line means the contractor is either skipping the inspection (which voids your manufacturer warranty) or burying the fee in labor.

What brand of AC is best for Dallas heat?

Carrier, Trane, Lennox, and Rheem all manufacture equipment rated for the Dallas climate envelope. The variable-capacity flagship models (Carrier Infinity 26, Trane XV20i, Lennox SL series) handle Dallas humidity and extended runtime better than baseline single-stage units. Brand differences matter less than installation quality; a poorly installed Trane will underperform a well-installed Goodman. Pick the brand based on parts availability through a local distributor, dealer reputation, and warranty terms rather than marketing claims.

How long does a new AC last in Dallas?

A new AC in Dallas typically lasts 12 to 17 years for a single-stage system and 14 to 20 years for a variable-capacity inverter system, with annual professional maintenance. Dallas runtime hours are higher than the national average because the cooling season runs from late April through October, so Dallas systems accumulate equivalent wear faster than systems in milder climates. Annual maintenance, coil cleaning, and capacitor monitoring extend the realistic Dallas service life by 2 to 4 years.

Will my Dallas electric bill go down with a new AC?

Yes, but the savings depend on what you are replacing. Stepping from a 12-year-old 13 SEER system to a new 16 SEER2 unit typically cuts summer cooling electricity use by 18 to 28%, which translates to $40 to $90 per summer month on a typical Dallas home. Stepping from a 5-year-old 14 SEER to a new 16 SEER2 unit saves only 6 to 10%, which is harder to detect on a bill. Use the savings as a tiebreaker between mid-tier and high-efficiency, not as the primary purchase justification.

Should I replace my furnace at the same time as my AC in Dallas?

If your gas furnace is over 15 years old, has had a heat exchanger crack or repair, or is below 80% AFUE, replace it with the AC. Combined replacement saves $1,200 to $2,000 in labor versus two separate trips and aligns the equipment lifecycle so you face the next decision in 12 to 17 years instead of staggered. If the furnace is under 10 years old and operating normally, keep it and replace only the AC and coil. The cost-benefit flips around year 12.

What size AC do I need for a 1500 square foot Dallas home?

A 1,500 square foot Dallas home typically needs a 2.5-ton to 3-ton AC system, with the exact size determined by a Manual J load calculation. The Dallas rule of thumb of 600 square feet per ton puts a 1,500 square foot home at 2.5 tons, but homes with vaulted ceilings, west-facing glass, or poor insulation push toward 3 tons. Installed pricing runs $5,300 to $9,800 for a 2.5-ton system and $5,800 to $10,500 for a 3-ton system in 2026.

Is a heat pump a better choice than an AC in Dallas?

A heat pump makes sense in Dallas when you currently heat with electric resistance (baseboard or electric furnace), when your gas furnace is also due for replacement, or when you want to eliminate a separate gas bill. Modern variable-capacity heat pumps deliver excellent cooling in Dallas summers and adequate heating through Dallas winters, which rarely drop below 25 degrees. The installed premium over an equivalent AC plus gas furnace runs $1,500 to $3,500. The breakeven depends on your retail electricity plan; see our heat pump vs central AC comparison for the math.
