Replacement Windows in Ann Arbor, Michigan
Ann Arbor is a Washtenaw County university city with mixed older neighborhoods and higher-value stock facing real Michigan winters — freeze-thaw, snow, and heating-dominated bills. About 64.3% of homes predate 1980 and the median year built is 1971. ENERGY STAR Northern / IECC 5A applies (same Michigan family as Detroit and Lansing): low U-factor is the money metric.
Short answer
In Ann Arbor, a standard replacement window (double-hung, casement or slider) typically costs $565–$3,215 installed. Bay and bow windows run $2,825–$9,035+, and a sliding patio door $1,695–$5,645. Frame material and the glass package decide where a project lands in that range.

What drives window decisions in Ann Arbor
- Michigan Northern / 5A: prioritize U-factor (ENERGY STAR Northern v7.0 family); do not copy Ohio North-Central brochure numbers.
- Mixed stock: older near-campus and downtown fabric plus mid-century and newer subdivisions — assess opening condition, not one stereotype.
- Freeze-thaw and snow stress old putty and sills; air sealing quality matters as much as glass package.
- DTE territory efficiency programs and Michigan IRA pathways when live; 25C expired.

Efficiency requirements for Ann Arbor's climate
Ann Arbor sits in the ENERGY STAR Northern zone (IECC zone 5A (cool, moist), Washtenaw County). Under the v7.0 specification, qualifying windows need a U-factor of 0.22 or lower with a solar heat gain coefficient (SHGC) of at least 0.17. Heating-dominated climate: the window must hold heat in (very low U-factor) while still letting some free solar warmth through in winter (minimum SHGC). Equivalent-performance tradeoffs allow U-factors of 0.23–0.26 when paired with progressively higher solar gain.
Not sure what these numbers mean? Read our plain-English guide to U-factor and SHGC.
What replacement windows cost here
Ann Arbor pricing often runs above Flint or Lansing averages because of labor demand and higher-spec product choices, but old openings still create bid spreads (full-frame vs insert, lead-safe work). Federal 25C is gone; utility efficiency programs are the realistic incentive path. Itemize every bid.

Rebates & incentives in Michigan
The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.
Michigan runs IRA Home Energy Rebate programs (administered through the state energy office); whole-home efficiency retrofits can include windows. Confirm current status and funding availability first.
- DTE Energy / Consumers Energy efficiency programs. Michigan's major utilities run Energy Waste Reduction programs offering audits and weatherization incentives; window measures typically qualify within a whole-home efficiency project. (DTE Energy, Consumers Energy program pages)
Michigan enforces the statewide Michigan Uniform Energy Code (IECC-based); Detroit permits and inspections run through BSEED (Buildings, Safety Engineering and Environmental Department).

Ann Arbor window replacement FAQ
›Do I need a permit to replace windows in Ann Arbor?
Usually yes for full replacement. City of Ann Arbor Building Department handles city permits; surrounding Washtenaw townships have their own building departments. Confirm the installer pulls the correct permit for your address.
›What efficiency numbers should Ann Arbor windows hit?
Ann Arbor is ENERGY STAR Northern and IECC 5A: U-factor 0.22 or lower under v7.0 (with equivalent-energy tradeoffs). Heating dominates; read the NFRC label on the exact unit.
›Are there rebates for windows in Ann Arbor?
Federal 25C expired December 31, 2025. Check DTE Energy Waste Reduction programs and Michigan IRA Home Energy Rebate status. Expect whole-home weatherization pathways more often than a large standalone window rebate.
›Restore original sash or replace?
Sound wood double-hungs can sometimes be restored and stormed — common on character homes near campus. When sashes are rotted or seals have failed systemically, modern insulated units are the durable path. Assess frame and sill condition first.
