The Summer Heat Is Real—Let’s Cool You Down

It’s that time of year again—the sun blazes, the humidity climbs, and your old window unit just isn’t cutting it anymore. You’re not alone. Thousands of homeowners and renters are searching for reliable, efficient ways to keep their living spaces cool without sacrificing style, space, or sanity. If you’ve been eyeing a through the wall air conditioner, now might be the perfect time to act. Why? Because we’re in the middle of the best through the wall air conditioner sale season.

Unlike portable or window units, through-the-wall ACs offer a more permanent, sleek, and powerful cooling solution. They’re built into your wall, so they don’t block your view or take up floor space. And right now, with summer in full swing and back-to-school shopping in the rearview, retailers are slashing prices to clear inventory. Whether you’re replacing an old unit, upgrading your HVAC setup, or installing one for the first time, this is your moment to save big.

What Is a Through the Wall Air Conditioner? (And Why You Should Care)

Let’s start with the basics. A through the wall air conditioner is a self-contained cooling unit installed directly into an exterior wall. Unlike window units that sit on the sill and block your view, these units are recessed into the wall, with the indoor side flush against the wall and the outdoor side venting heat outside. They’re permanent fixtures—think of them like mini split systems without the ductwork.

How It Works

The unit pulls warm air from your room, cools it using a refrigerant cycle, and expels hot air outside through the back. Most models come with a built-in sleeve (a metal frame that sits in the wall) to support the unit and seal it from drafts. The indoor panel includes controls, a fan, and often a remote for easy operation.

For example, the Frigidaire FHTC123WA1 uses a 12,000 BTU compressor to cool rooms up to 550 sq. ft. It’s installed into a standard 24-inch wall opening and vents directly outside—no window needed. That means you can keep your windows free for plants, blinds, or even a cat who loves sunbathing.

Benefits Over Other AC Types

• Space-saving: No floor clutter or window blockage.
• Better insulation: Once sealed properly, they prevent drafts and air leaks.
• Higher efficiency: Many models have higher SEER ratings than portable units.
• Aesthetic appeal: Sleek, low-profile design blends into walls.
• Long-term investment: Durable and often lasts 10+ years with maintenance.

One homeowner in Phoenix told me: “I hated my window unit. It rattled, blocked my view, and made the room feel smaller. After installing a through-the-wall unit, my bedroom feels open, quiet, and cool.” That’s the kind of transformation we’re talking about.

Who Should Consider This Type of AC?

Through-the-wall air conditioners are ideal for:

• Rooms with limited window space (like basements or interior bedrooms)
• Homes with historic preservation rules that limit window modifications
• People who want a permanent, professional-looking cooling solution
• Those upgrading from portable or outdated window units

Just remember: installation requires cutting a hole in the wall and possibly hiring an electrician if you need a dedicated circuit. But if you’re handy with tools, some models come with DIY-friendly kits.

Why Now Is the Best Time for a Through the Wall Air Conditioner Sale

Timing is everything—especially when it comes to home cooling. The best through the wall air conditioner sale deals usually happen in two key windows: late spring (May–June) and late summer (August–September). Here’s why now—late summer—is a golden opportunity.

Retailers Clear Out Summer Inventory

Big-box stores like Home Depot, Lowe’s, and Best Buy stock up in spring for the summer rush. By August, they’re eager to clear space for fall appliances (think heaters, humidifiers, and smart thermostats). That means deep discounts—often 20% to 30% off—on remaining AC units.

For example, in 2023, Lowe’s ran a “Last Chance Summer Savings” event in August, offering the LG LW1216HR (12,000 BTU, heat & cool) for $449—down from $599. That’s a $150 savings just for waiting a few months.

Manufacturer Rebates & Seasonal Promotions

Brands like Frigidaire, GE, and Haier often partner with energy companies or retailers to offer rebates. In 2024, Frigidaire is running a “Cool & Save” promo: buy any qualifying through-the-wall AC between August 1 and September 30, and get a $75 mail-in rebate. Combine that with a sale price, and you could save $200+.

Pro tip: Check EnergyStar.gov for federal and state rebates. Some states (like California and New York) offer additional incentives for high-efficiency models.

Back-to-School & Labor Day Sales

August and September bring two major shopping holidays: back-to-school and Labor Day. Retailers use these events to attract budget-conscious shoppers. In 2023, Home Depot’s Labor Day sale included:

• 25% off select through-the-wall ACs
• Free delivery on orders over $350
• Extended return windows (up to 90 days)

Even online retailers like Amazon and Wayfair join in. In fact, Amazon’s “End of Summer Cooling Sale” in August 2023 featured the Keystone KSTAT12-2C at $379 (normally $499) with Prime delivery.

Don’t Wait Until Next Year

Here’s a reality check: if you wait until next summer, prices will rise again. Demand spikes in May and June, and supply chain issues can cause shortages. By buying now, you lock in lower prices, avoid rush fees, and get your unit installed before the next heatwave hits.

How to Choose the Right Through the Wall AC (Without Regret)

Buying an AC isn’t just about price. You need the right size, features, and installation plan. Here’s how to avoid buyer’s remorse.

Step 1: Measure Your Room

BTUs (British Thermal Units) tell you how much cooling power you need. As a rule of thumb:

• 150–250 sq. ft. → 6,000–8,000 BTUs
• 250–400 sq. ft. → 9,000–10,000 BTUs
• 400–550 sq. ft. → 12,000–14,000 BTUs
• 550+ sq. ft. → 15,000+ BTUs

For example, a 300 sq. ft. bedroom needs about 9,000–10,000 BTUs. Over-sizing (e.g., 14,000 BTUs) can cause short cycling, which wastes energy and reduces humidity control.

Step 2: Check Wall Compatibility

Most through-the-wall ACs fit a 24” x 18” opening, but always check the specs. Your wall must be:

• At least 8 inches thick (to accommodate the sleeve)
• Free of pipes, wires, or structural supports
• Exterior-facing (to vent heat outside)

Use a stud finder to map your wall. If you’re unsure, consult a contractor.

Step 3: Prioritize Energy Efficiency

Look for the EnergyGuide label. It shows estimated annual energy cost. A 12,000 BTU unit with a SEER of 10.5 might cost $85/year to run, while a SEER 9 model could cost $100+. Over 10 years, that’s $150 in savings.

Also, check for the Energy Star certification. These models are 15% more efficient than standard units.

Step 4: Consider Noise Level

Measured in decibels (dB), noise ranges from 50 dB (quiet library) to 65 dB (normal conversation). For bedrooms, aim for 58 dB or lower. Check user reviews for real-world noise reports.

Step 5: Think Long-Term

• Warranty: Look for at least 1-year parts and labor, 5-year compressor.
• Installation: DIY kits save money, but pros ensure proper sealing and electrical safety.
• Maintenance: Easy-access filters and washable components save time.

Installation Tips & Cost-Saving Hacks

Installing a through-the-wall AC isn’t rocket science, but it does require care. Here’s how to do it right—and save money in the process.

DIY vs. Professional Installation

If you’re handy, a DIY install can save $200–$400. Most units come with a wall sleeve and mounting kit. You’ll need:

• Circular saw or reciprocating saw
• Level
• Drill
• Caulk gun
• Helper (units weigh 60–80 lbs)

Steps:

1. Mark the hole using the sleeve template.
2. Cut the wall from the outside (safer and cleaner).
3. Install the sleeve, seal with caulk.
4. Slide in the unit, secure with screws.
5. Connect to a dedicated 115V or 230V outlet (check manual).
6. Seal gaps with foam or weatherstripping.

Pro tip: Install in the morning or evening to avoid heat stress. And always wear safety goggles.

When to Hire a Pro

If your wall has brick, stucco, or metal siding, or if you need a new electrical circuit, hire a licensed contractor. Expect to pay $300–$600, but it’s worth it for safety and code compliance.

Cost-Saving Hacks

• Buy during a sale: As we’ve discussed, late summer is prime time.
• Bundle with accessories: Some retailers offer free thermostats or remote controls with purchase.
• Use a credit card with rewards: Many offer cash back on home improvement purchases.
• Check for free delivery: Home Depot and Lowe’s often waive fees for large appliances.
• Negotiate: Some stores will match a lower online price if you ask.
