Vermont HVAC Replacement Cost (2027): AC and Heat Pump Prices
Adjust your home size & electric cost in Vermont
Every price on this page is built around a 2,000 sq. ft. home, the common size in Vermont, cooled by a 3-ton system of about 36,000 BTU. Our pick for Vermont is 14 SEER. Expect $7,990 to $9,630 for the full install; the ten-year charts below show why it beats the other ratings.
Zone 1 weather gives Vermont cool summers, with highs averaging 79.5°F. Our model counts about 9.3 hours of daily run time across a 103-day season, so a 16 SEER unit uses about 2,443 kWh, roughly $830 of electricity a year.
We price one central AC or heat pump on working ductwork. Big houses often split the load across two systems, and ductless heads are a separate quote.
Vermont AC Replacement Cost, 14 to 20 SEER
Below: installed ranges for Vermont, the equipment share of each job, and the power each rating burns in an average season here.
| 3-ton system | Installed | Equipment | Power / season | Cooling / yr |
|---|---|---|---|---|
| 14 SEER | $7,990 – $9,630 | $5,030 | 2,751 kWh | $940 |
| 16 SEER | $10,150 – $12,230 | $6,310 | 2,443 kWh | $830 |
| 18 SEER | $15,450 – $18,630 | $9,480 | 2,203 kWh | $750 |
| 20 SEER | $21,430 – $25,830 | $13,040 | 2,012 kWh | $690 |
Entry-level 14 SEER equipment ($7,990 to $9,630 installed, $5,030 of it hardware) draws about 2,751 kWh a season here. A 16 SEER system ($10,150 to $12,230, $6,310 of hardware) needs about 2,443 kWh for the same cooling. A heat pump cools at the same SEER and heats as well – see the heat pump calculator.
Local Prices Across Vermont
Where you live inside Vermont moves the bid. Metro crews carry more overhead; small-town installers usually less. The same 16 SEER system, priced for the state's largest cities:

Vermont Electric Rates and Your AC's Running Cost
The rate is what turns SEER into dollars. Vermont pays $0.339 per kWh today, 56% above the U.S. figure of $0.217, and the state's rate has climbed roughly 2.07% a year. Project that forward and 2036 brings about $0.42/kWh.
Hover or tap any year to see what each rating costs to run that season. Rates rise 2.07% a year, the VT ten-year trend.
Starting point: this summer at VT's current rate. From there the rate grows 2.07% per year, compounded, and each season cost is rounded up to $10.
The lines spread apart as rates rise. Today 9 SEER costs $1,470 a season and 14 SEER $940; by 2036 those become $1,800 and $1,150.
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 3-ton system at Vermont electric rates ($0.339/kWh, rising 2.07% a year).
| Installed price of the new system | $8,690 |
| Electricity saved, first year | $540 |
| Saved over 10 summers (rates rising) | $5,850 |
| Payback | 14.2 years |
| Net after 10 summers | -$2,840 |
Not on savings alone: 9 to 14 SEER is $2,840 short after 10 summers in VT.
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.
Vermont: Replacing a 9 SEER Unit, Price vs Payback
| 9 SEER | 14 SEER | 16 SEER | 18 SEER | 20 SEER | |

Payback counts the 2.07% yearly rate rise; the green column is the best ten-year value.
Verdict for VT: 14 SEER. Higher ratings cut the bill, but not by enough to cover their cost here.
Comparing 14 and 18 SEER bids? The $8,120 gap needs about 31.4 years of savings in VT, so the upgrade is mostly about comfort.
Total Cost to Own Each SEER in Vermont
Buy Price vs 10-Year Running Cost: Total Cost of Ownership in VT
For each SEER rating: the installed price, 10 years of cooling electricity at Vermont rates (rising 2.07% a year), and the two added together. The shortest total bar is the cheapest system to own. Hover or tap a bar for the math.
Cheapest over 10 years in Vermont: 14 SEER at $18,940 all-in, made of $8,690 to install plus $10,260 to run.
Includes energy inflation: electricity = this season's cost at today's VT rate, then each of the next nine seasons raised by the historic 2.07%/yr rate increase. Install = the typical installed price on this page. Each figure is rounded up to the next $10 on its own, so the two parts can add up to $10 more than the total.
During peak months, a 14 SEER system in VT uses about 801 kWh, near $280 at today's rate. An older, less efficient unit costs more for the same comfort.
High-Efficiency Systems: 18 and 20+ SEER
Vermont bids for 18 SEER run $15,450 to $18,630. Most of the premium buys the compressor and controls, and the saving shows up as about 2,203 kWh a season instead of 2,443.
Shopping in the Burlington area? An 18 SEER install there runs about $15,470 to $18,650.
The 20 SEER range in Vermont is $21,430 to $25,830. Name brands add more on top: about $31,440 for a Lennox XP20, past $41,460 for an SL25XPV.
Tip: Armstrong Air belongs to the same parent company as Lennox and is often quoted lower for comparable equipment. Ask for both prices.
Compared on electricity alone, 20 SEER wins: 2,012 kWh a season, a 27% cut from 14 SEER and 53% from 9 SEER. At VT rates that saving does not cover the premium within ten years.
Built for Vermont Summers and Winters
Beyond size (an average-size unit for a Zone 1 home), Vermont's climate affects which equipment and options are worth paying for.
Climate zones run from 1 (cool) to 5 (hot); Vermont is in Zone 1.
Short summers. With a cooling season of about 103 days, high-SEER equipment saves less here than in hot states. Spend on the right size and a good installation first.
Four seasons. Buying an AC in Vermont is a good moment to price a heat pump as well. At equal SEER the cooling cost is the same; the difference is the winter bill.
Snow and ice. In winter, a cooling-only condenser needs nothing more than a top cover. A heat pump runs all winter, so it must stay raised and clear.
When to buy: almost any month works in Vermont. Just avoid the first hot week, when every homeowner calls at once.

Reading a SEER Rating
SEER is the cooling a unit delivers over a season divided by the electricity it uses. Higher SEER, same cooling, smaller bill.
The math also works in reverse. A 36,000 BTU system rated 14 SEER draws about 36,000 ÷ 14 = 2,571 W at the compressor. Add roughly 300 W for the indoor blower, and the whole system pulls about 2.87 kW while running.
Newer labels show SEER2, a stricter test that prints a slightly lower number for the same machine. Compare SEER to SEER, or SEER2 to SEER2.
Rough sizing by floor area and climate zone – VT is Zone 1:
| AC Size | ZONE 1 | ZONE 2 | ZONE 3 | ZONE 4 | 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. |
Treat these as ballpark sizes. Insulation, windows and shade change the answer, which is why installers run a Manual J.
