HVAC Replacement Cost in Texas: Installed Prices by SEER, 2027
Adjust your home size & electric cost in Texas
Most homes in Texas come in near 2,170 sq. ft. Size the cooling to that and you get about 48,000 BTU of capacity, which the trade sells as a 4-ton unit. Our pick for Texas is 16 SEER. Expect $9,610 to $11,580 for the full install; the ten-year charts below show why it beats the other ratings.
Zone 5 weather gives Texas hot summers, with highs averaging 96.1°F. Our model counts about 14.3 hours of daily run time across a 143-day season, so a 16 SEER unit uses about 6,748 kWh, roughly $1,340 of electricity a year.
Figures assume one ducted central system. Ductless mini-splits are priced on their own, and homes that need more than five tons usually get two smaller units.
What a New Central AC Costs in Texas
Here is what a 4-ton install costs in Texas at each efficiency level. Equipment is about 57% of a 14 SEER bid; labor, refrigerant lines, the pad and electrical work make up the rest.
| 4-ton system | Installed | Equipment | Power / season | Cooling / yr |
|---|---|---|---|---|
| 14 SEER | $7,690 – $9,270 | $4,800 | 7,625 kWh | $1,520 |
| 16 SEER | $9,610 – $11,580 | $5,940 | 6,748 kWh | $1,340 |
| 18 SEER | $14,680 – $17,690 | $8,970 | 6,067 kWh | $1,210 |
| 20 SEER | $20,140 – $24,280 | $12,220 | 5,521 kWh | $1,100 |
New central ACs in Texas must meet the federal Southeast/Southwest efficiency minimum, which 14 SEER equipment misses. In practice 16 SEER, at $9,610 to $11,580 with $5,940 of hardware, is the entry point; it uses about 6,748 kWh a season. If the furnace is old too, run the heat pump calculator before you decide.

Which SEER Pays Off in Texas?
The rate is what turns SEER into dollars. Texas pays $0.199 per kWh today, 9% below the U.S. figure of $0.217, and the state's rate has climbed roughly 2.47% a year. Project that forward and 2036 brings about $0.25/kWh.
Hover or tap any year to see what each rating costs to run that season. Rates rise 2.47% a year, the TX ten-year trend.
Starting point: this summer at TX's current rate. From there the rate grows 2.47% per year, compounded, and each season cost is rounded up to $10.
Over the next ten summers, keeping a 9 SEER unit costs about $26,540 in electricity; a 16 SEER system needs about $14,990 for the same cooling.
Upgrade Payback Finder: Your Old AC vs a New One
Pick the unit you have and the one you are considering. Figures are for a 4-ton system at Texas electric rates ($0.199/kWh, rising 2.47% a year).
| Installed price of the new system | $10,440 |
| Electricity saved, first year | $1,040 |
| Saved over 10 summers (rates rising) | $11,560 |
| Payback | 9.1 years |
| Net after 10 summers | +$1,120 |
Pays off: going from 9 to 16 SEER leaves you $1,120 ahead after 10 summers in TX.
These figures treat the whole install as the price of switching from a unit that still runs. Replacing a dead unit? Use the 14 SEER comparison table lower on the page.

All figures for a 4-ton system at TX rates, rising 2.47% a year; green marks the strongest ten-year result. Reference only: a 14 SEER central AC can no longer be newly installed in Texas, which sits in the federal southern efficiency region.
Verdict for TX: among the ratings you can legally install, 16 SEER is the cheapest to own over ten years ($25,430).
Total Cost to Own Each SEER in Texas
Buy Price vs 10-Year Running Cost: Total Cost of Ownership in TX
Install price plus ten seasons of electricity at Texas rates, growing 2.47% yearly, gives the real price of each system. Compare the total bars: the shortest one wins. Hover or tap for the breakdown.
After 10 years, 16 SEER is the cheapest system to own in Texas: $25,430 all-in ($10,440 installed + $14,990 of electricity).
Energy inflation is built in: season one is priced at today's TX rate, and each of the nine seasons after it costs 2.47% more than the one before, the historic yearly increase. The install figure is the typical installed price on this page. Parts and totals are each rounded up to $10, so the parts may sum $10 above the total. 14 SEER is left out: it is below the federal minimum for new central AC installs in Texas.
Expect about $290 a month for cooling in season: 1,416 kWh from a 3.3 kW system running some 14.3 hours a day, priced at $0.199.
Premium Efficiency in Texas: 18 SEER and Up
Expect $14,680 to $17,690 for an 18 SEER system in Texas. It cools the same house on about 6,067 kWh a season, against the 6,748 kWh a 16 SEER unit needs.
Around Houston, budget roughly $15,490 to $18,680 for 18 SEER – the metro premium applies at every rating.
For 20+ SEER, plan on $20,140 to $24,280 at TX prices. A Lennox XP20 can reach $29,550; the SL25XPV starts around $38,960.
Tip: sister brands can save real money. Armstrong Air is owned by Lennox's parent company and usually costs less for a similar unit.
Season-long, 20 SEER needs about 5,521 kWh. That is 28% under a 14 SEER system and 54% under a worn 9 SEER unit. At TX rates that saving does not cover the premium within ten years.
Climate Factors for Cooling in Texas
Zone 5 summers in Texas are hot; that alone calls for a larger-than-average unit. The weather also brings its own wear and tear.
Climate zones run from 1 (cool) to 5 (hot); Texas is in Zone 5.
Dry heat. Long, hot days mean long run hours, so efficiency pays back faster here than in most states. Ducts in a hot attic can lose much of the cooling; have them sealed and insulated when the system is replaced.
Moisture load. Sticky TX weather rewards equipment that runs longer at lower speed, because it pulls more water out of the air. Ask the installer how the system handles humidity, not just temperature.
Hail belt. Texas gets hail that bends condenser fins. A fin comb fixes light damage; heavy damage cuts efficiency and can justify an insurance claim.
Storm season. Outdoor units should be anchored to the pad, and many coastal codes require tie-downs. A whole-house surge protector guards the control board when power comes back.
Timing: a mid-summer breakdown leaves you no time to compare bids. If your system is aging, get quotes in the off-season.

SEER Explained in Plain Numbers
Think of SEER as miles per gallon for cooling: BTUs of heat removed per watt-hour of power, averaged over a season.
For the 48,000 BTU system this page prices, 16 SEER works out to 3,000 W of compressor draw (48,000 ÷ 16). The fan adds about 300 W, for roughly 3.3 kW in total.
Shopping tip: equipment rated under the newer rules carries a SEER2 number, which reads lower than old-style SEER for the same unit.
Rough sizing by floor area and climate zone – TX is Zone 5:

|---|---|---|---|---|---|
| 1.5 Ton | 700-1100 s.f. | 700-1050 s.f. | 500-1000 s.f. | 500-950 s.f. | 500-900 s.f. |
| 2 Ton | 1101-1400 s.f. | 1051-1350 s.f. | 1001-1300 s.f. | 951-1250 s.f. | 901-1200 s.f. |
| 2.5 Ton | 1401-1650 s.f. | 1351-1500 s.f. | 1301-1500 s.f. | 1251-1550 s.f. | 1201-1500 s.f. |
| 3 Ton | 1651-2100 s.f. | 1601-2000 s.f. | 1601-1900 s.f. | 1501-1850 s.f. | 1501-1800 s.f. |
| 3.5 Ton | 2101-2300 s.f. | 2001-2250 s.f. | 1901-2200 s.f. | 1851-2150 s.f. | 1801-2100 s.f. |
| 4 Ton | 2301-2700 s.f. | 2251-2700 s.f. | 2201-2500 s.f. | 2151-2500 s.f. | 2101-2400 s.f. |
| 5 Ton | 2701-3300 s.f. | 2751-3300 s.f. | 2601-3200 s.f. | 2501-3100 s.f. | 2401-3000 s.f. |
Ask for a written Manual J. Bigger is not better: an oversized system costs more and controls humidity worse.
