What Is a Wall AC Unit?
A wall AC unit is a self-contained air conditioning system installed directly into an exterior wall. Unlike window units, these devices are permanently mounted, providing efficient cooling without obstructing windows. Common in apartments, offices, and homes without central air, wall AC units can cool individual rooms or small spaces.
Types of Wall AC Units
There are two primary types of wall AC units:
- Through-the-Wall AC Units: Designed specifically to fit into a wall sleeve, these units differ from window models by their sealed installation and usually have higher energy efficiency.
- Ductless Mini-Split Systems: These combine a wall-mounted interior unit with an exterior compressor. They offer both heating and cooling capabilities and are highly energy-efficient but cost more upfront.
Wall AC Unit Price Ranges in 2025
Entry-Level Models
Basic through-the-wall AC units usually cost $400 to $700. These models offer lower cooling capacities (8,000–10,000 BTUs), suitable for small rooms up to 400 square feet.
Mid-Range Models
Mid-range models fall between $700 and $1,200. These deliver higher BTUs (10,000–15,000), better energy ratings, and more features like remotes, timers, and multi-speed fans.
High-End Models
Premium wall AC units and ductless mini-splits typically cost $1,200 to $1,800 or more. They offer advanced controls, inverter technology, Wi-Fi connectivity, and superior efficiency, covering up to 700 square feet.
Mini-Split System Costs
Ductless mini-splits often range from $1,200 to $2,800 per zone (cooling area), excluding installation. Each additional zone increases the equipment and labor costs.
Key Features Impacting Wall AC Unit Cost
- BTU Rating: Higher BTU units cool larger spaces and cost more.
- Energy Efficiency (EER/SEER): Energy-efficient models have lower operating costs but higher initial prices.
- Smart Controls: Features like Wi-Fi control, timers, and thermostats add to the price.
- Brand: Well-known brands (e.g., Friedrich, LG, Frigidaire) generally come at a premium.
- Noise Level: Quieter units use advanced technology, impacting cost.
- Heating Capability: Some units offer heat pumps, which can increase your investment.
Installation Costs for Wall AC Units
Installation expenses are a significant part of the total wall AC unit cost. Typical costs are as follows:
- New Installation (No Existing Hole): $600–$1,200, with the higher end covering wall preparation, electrical work, and weatherproofing.
- Replacement Installation (Using Existing Sleeve): $400–$800, since less work is required.
Labor rates vary by region, job complexity, and whether electrical upgrades are needed. Adding a dedicated circuit can cost an additional $200–$600.

Factors That Influence Installation Price
- Wall Material: Cutting through brick or stone raises costs compared to wood or vinyl siding.
- Electrical Requirements: Upgrading wiring, adding outlets, or circuit breakers increases labor charges.
- Unit Size and Weight: Larger units require sturdier sleeves and more extensive support.
- Accessibility: Higher floors or limited exterior access can increase time and effort.
DIY Wall AC Unit Installation: Pros and Cons
Some homeowners consider DIY installation to save money on labor. While this can reduce expenses, it’s best suited for those with previous experience.
- Pros: Save on professional labor costs, schedule at your convenience.
- Cons: Risk of incorrect installation, warranty voiding, injury, and increased energy inefficiency. Specialized tools and electrical knowledge are often required.
Operating Costs and Energy Efficiency
The operating cost of a wall AC unit depends on efficiency ratings, usage patterns, and local electricity prices. In the U.S., the average annual running cost is $100 to $300, assuming 6–8 hours daily use during summer months.
How Efficiency Ratings Affect Savings
Modern wall AC units list either an Energy Efficiency Ratio (EER) or a Seasonal Energy Efficiency Ratio (SEER). Higher numbers mean better energy use, lowering monthly bills. ENERGY STAR-certified models can reduce energy costs by up to 30% compared to older units.
Wall AC Units vs. Window AC Units: Cost Comparison
| Feature | Wall AC Unit | Window AC Unit |
|---|---|---|
| Equipment Cost | $400 – $1,800 | $200 – $800 |
| Installation Cost | $400 – $1,200 | $50 – $150 |
| Energy Efficiency | Higher (especially mini-split) | Generally lower |
| Durability | Designed for permanent use | Removable, less durable |
| Home Value Impact | May add value | Limited impact |
