What a New HVAC System Costs in Ann Arbor, MI (2027)
Adjust your home size & electric cost in Ann Arbor, MI
Start with the house: 1,720 sq. ft. calls for about 33,000 BTU, a 3-ton unit. In Ann Arbor, the 14 SEER version of that system costs $7,690 to $9,270 installed and gives the lowest ten-year total of the ratings we price. Expect Ann Arbor bids to land roughly 1% above the Michigan average; the city has about 120,000 residents and the costs that come with that.
The price assumes your ducts can stay. When an installer finds crushed runs, too few returns or a dated disconnect, those repairs show up as added lines.
Four Ratings, Four Prices: Ann Arbor
From the cheapest 14 SEER bid ($7,690) to the priciest 20 SEER one ($22,210), Ann Arbor quotes for a 3-ton system span a wide band. Most buyers sit in the middle: 16 SEER at $9,710 to $11,700 or 18 SEER at $14,330 to $17,270.
Price by Rating: Ann Arbor and Statewide
| System (3 ton) | Ann Arbor | Michigan average | Materials |
|---|---|---|---|
| 14 SEER | $7,690 - $9,270 | $7,580 - $9,140 | $4,840 |
| 16 SEER | $9,710 - $11,700 | $9,570 - $11,540 | $6,050 |
| 18 SEER | $14,330 - $17,270 | $14,120 - $17,020 | $8,800 |
| 20 SEER | $18,430 - $22,210 | $18,160 - $21,890 | $11,240 |
Hardware for a 16 SEER system costs around $6,050. The gap between that and the installed Ann Arbor price is the labor and overhead of doing the job right.
The Ann Arbor Price Adjustment, Explained
Demand moves prices too. When local crews are booked solid, bids stay firm; where installers compete for work, there is room to negotiate. That premium adds roughly $160 to a typical 16 SEER job in Ann Arbor, compared with the statewide $9,570 to $11,540.
We apply these figures across Ann Arbor's 8 ZIP codes (Washtenaw County), downtown and edge alike. Equipment warranties often need registration within a set window. Ask the installer to register the unit and to put the labor warranty in writing.
What Ann Arbor Pays to Keep Cool
We price Ann Arbor running costs at the Michigan average of $0.276/kWh (about 27% above the national average of $0.217); if your bill shows a different rate, enter it in the form above. A 2.44% yearly rise in Michigan electric rates, the decade trend, is built into every ten-year number on this page.
Each line is one SEER rating; touch or hover a year to read its dollar figures. The climb is the 2.44% yearly increase MI rates showed over ten years.
The first point applies MI's current rate to this season; every point after it adds another year of the 2.44% average increase. Dollar figures are rounded up to the next $10.
Expect about $630 a year to cool with 16 SEER in Ann Arbor (2,263 kWh), against $1,110 with an old 9 SEER system.

Pick the unit you have and the one you are considering. Figures are for a 3-ton system at Michigan electric rates ($0.276/kWh, rising 2.44% a year).

| Electricity saved, first year | $410 |
| Saved over 10 summers (rates rising) | $4,490 |
| Payback | 17.0 years |
| Net after 10 summers | -$3,880 |
Not on savings alone: 9 to 14 SEER is $3,880 short after 10 summers in MI.
Replacing a working unit: the whole install counts as the cost. If the old one has failed, weigh each rating against a 14 SEER quote instead.

Buy Price vs 10-Year Running Cost: Total Cost of Ownership in MI
For each SEER rating: the installed price, 10 years of cooling electricity at Michigan rates (rising 2.44% 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.
Lowest 10-year total in Michigan: 14 SEER, $16,200 ($8,360 up front, $7,840 in electricity).
Includes energy inflation: electricity = this season's cost at today's MI rate, then each of the next nine seasons raised by the historic 2.44%/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.

What Ann Arbor Summers Ask of an Air Conditioner
Statewide numbers frame the Ann Arbor estimate: region 1 on our map, summer highs averaging about 82°F, and winter highs around 28°F. Cooling hours in Ann Arbor are few next to heating hours, so the furnace or heat pump deserves as much attention as the AC rating.
Climate zones run from 1 (cool) to 5 (hot); Michigan is in Zone 1.
In humid Ann Arbor weather, the AC is also a dehumidifier, and it only works as one when it runs long enough.
Detroit is the nearest guide city to Ann Arbor, roughly 35 miles to the east.
Replacing the AC and the furnace together in Ann Arbor matches the indoor coil to the blower, which is how the cooling side reaches its rated efficiency. Older units were often oversized, so a Ann Arbor installer who copies the old tonnage may repeat the mistake. Ask for a load calculation.
Ductwork and Space in a Ann Arbor Install
Natural gas furnaces on ductwork are the common setup in Michigan, which keeps a Ann Arbor AC swap fairly simple; older ducts may still need sealing. Most Ann Arbor jobs are detached houses with open yard space for the condenser, which keeps the install simple.
For one finished attic or an addition, a single-zone mini-split usually costs less than extending the ducts.
Timing, Permits and Paperwork in Ann Arbor
Replace an old system in spring or fall. Ann Arbor crews have open calendars then, and the house can go a day without heat or AC. A licensed Michigan contractor who pulls the permit gives you a record to point to if a problem shows up later.

Quick Answers
Figures below use Michigan averages; energy prices as of October 2026.
Does a heat pump heat for less than natural gas in Michigan?
No, natural gas still wins in Michigan: 82,913 BTUs per dollar against 37,129 for a heat pump at COP 3. The break-even power price is about 12.3¢ per kWh, and the Michigan average is 27.6¢. A more efficient heat pump narrows the gap.
Is electricity in Michigan expensive compared with other states?
Michigan pays 27.6¢ per kWh on average: 27% over the national figure of 21.7¢ and the 13th most expensive of 51. Cooling bills rise and fall with it.
Is a cold-climate heat pump needed in Michigan?
In most homes, yes. A statewide average winter low near 13°F is past the comfort zone of standard heat pumps; a cold-climate unit sized for the worst nights holds up.
What does a heat pump save over electric baseboard in Michigan?
Roughly two-thirds of the bill at COP 3. With the Michigan average at 27.6¢ per kWh, baseboard heat costs about $80.80 per million BTU and a heat pump about $26.93.
What is the best season to replace an AC or furnace in Michigan?
The shoulder seasons, spring and fall, ahead of need. Winter lows near 13°F statewide mean heating work should wrap up by early fall. The first heat wave and the first cold snap fill every installer's calendar; replacing on your own schedule leaves room to compare quotes.
Is it smart to replace the furnace and AC together?
When both are aging, generally yes: one visit, one labor charge, and a matched coil and condenser, which the efficiency rating assumes. If one is fairly new, price each job on its own.
