Installing a window air conditioner yourself saves hundreds on labor—you only pay for the materials. Use NailIt to estimate the exact cost of the AC unit, mounting hardware, sealants, and accessories you'll need to cool your space.
Estimated DIY materials cost for total materials for one window AC installation — you supply the labor. Prices vary by region and brand.
This is beginner-friendly — a confident DIYer can usually handle it and keep the labor savings. The pro figure is a rough rule of thumb (labor on jobs like this often runs 1–2.5× the materials) — always get real quotes. It is not a NailIt estimate.
NailIt estimates materials only, so here is the honest version of the labour question rather than a number we cannot stand behind. Installed, this job commonly lands somewhere around $560–$1,925 — that is the materials range above with labour applied at the rough 1–2.5× multiplier trades typically work to on jobs like this. It is a sanity check for reading a quote, not a NailIt estimate and not a substitute for a real one.
What actually moves that number: your region and local labour rates, access and prep work, whether a permit and inspection are involved, disposal of the old material, and how much the crew has to work around your schedule. For this project the DIY route is realistic for most homeowners, and the labour saving is the whole point. Always collect three written quotes from licensed, insured contractors and compare what each one includes — how we handle pricing.

No. NailIt is DIY-only and shows materials cost only. You do the installation work yourself, so labor is not included.
Choose BTU based on room size: 5,000 BTU for ~150 sq ft, 8,000 for ~350 sq ft, 12,000 for ~550 sq ft. Larger units cost more but cool faster.
Most window ACs plug into a standard outlet—no wiring required. However, if your outlet is far away or underpowered, consult an electrician (cost not included in NailIt estimate).
