🌬 Introduction
Jake thought buying his new 8,000 BTU through‑the‑wall AC was as simple as picking one online and plugging it in. The unit itself was $550—reasonable enough. But then came the wall sleeve, the installation tools, the sealant, and the unexpected weekend of labor.
By the time the job was done, Jake’s “$550 AC” had actually cost closer to $900.
This guide lays out everything Jake learned—so you’ll know the true costs of owning a 6,000–9,000 BTU wall AC, whether you’re going the DIY route or hiring a pro.

🧰 Step 2: Wall Sleeve Costs
🏠 What is a Wall Sleeve?
A wall sleeve is the frame that supports and houses the AC unit. It ensures stability, seals against the elements, and allows for easy replacement of the unit in the future.
Jake assumed the AC came with a sleeve—it didn’t.
💵 Typical Sleeve Prices

Standard Steel Sleeve (24"): $100–$200

Insulated Premium Sleeve: $150–$250

Universal Sleeves (fit multiple brands): $180–$300
Jake spent $200 on an insulated sleeve to cut down on noise and drafts.
📌 Home Depot recommends insulated sleeves for bedrooms or offices where noise and energy loss are a concern.
🔧 Step 3: DIY Installation Costs
Jake decided to install his AC himself—saving money but investing a full weekend.
🛠 Tools & Materials List
-
Reciprocating saw or circular saw: $50–$150
-
Drill + masonry bits: $40–$100
-
Level & tape measure: $20–$40
-
Insulation foam & weatherstripping: $20–$40

Exterior caulk: $10
-
Safety gear (gloves, goggles, dust mask): $20–$50
💰 Total DIY Extras
If you already own basic tools: $100–$150
If starting from scratch: $200–$300
Jake already had a drill and level, but had to buy a saw for $100.
📌 Family Handyman notes that proper tools are essential for cutting clean, safe openings in drywall and siding.
👷 Step 4: Hiring a Professional
Not everyone is comfortable cutting into an exterior wall. Jake priced out pro installation before deciding on DIY.
📊 Typical Professional Labor Costs
-
Standard Install (wood siding): $300–$600
-
Complex Install (brick, stone, or wiring work): $700–$1,200
Jake’s quote: $750 for his brick-wall office.
Pros usually include:
-
Wall sleeve installation
-
Proper sealing & insulation
-
Electrical safety check
-
Cleanup & warranty support
