Need a trailer that stays comfortable in extreme heat—or protects temperature-sensitive gear while you haul? An enclosed trailer with an AC unit turns a standard cargo trailer into a climate-controlled space for work, storage, and travel days when the sun is brutal.
At Make My Trailer, we build A/C-ready enclosed trailers the right way: A/C + electrical + insulation planned together so you get real cooling performance (not a “bolt-on” upgrade that struggles).

An air-conditioned enclosed trailer is still an enclosed cargo trailer at its core—secure, weather-protected, and lockable—but it’s configured so the A/C can actually do its job. Real-world performance comes down to three things:
A/C size (BTU output)
Proper electrical package (wiring + breakers + safe power delivery)
Insulation (so you’re not fighting constant heat gain)
When those pieces are matched correctly, you get a trailer that’s dramatically more usable—whether you’re working inside or protecting cargo from heat.
Most enclosed trailer A/C builds come down to two common choices:
13,500 BTU rooftop A/C – a popular, strong option for many small-to-mid enclosed trailer builds
15,000 BTU rooftop A/C – ideal when you want extra cooling headroom, have a larger trailer, or expect heavy sun exposure
Many buyers also choose a heat strip option for basic warmth in cooler weather. (Heat strips can “take the chill off,” but they’re not the same as a dedicated heater.) These common A/C package configurations match what buyers see across the market today.
A trailer A/C upgrade needs the correct electrical foundation. Air conditioner packages commonly require an electric package to support the A/C load safely and reliably.
If you plan to run lights, chargers, tools, or extra outlets, your electrical setup should be designed around real usage—not “just enough to run.”
If you want A/C that feels like it’s working, insulation matters. Insulation is widely recommended alongside trailer A/C packages for a reason: it helps the trailer cool faster and stay stable once it’s cooled.
Benefits of insulating walls and ceiling:
Faster cool-down
Less temperature swing
Better comfort inside
Reduced cycling and strain on the A/C
In plain terms: insulation makes your A/C upgrade worth it.
Many rooftop A/C systems use a standard-style roof opening (often referenced as 14-1/4″ x 14-1/4″)
But the most important part isn’t just the opening—it’s ensuring the roof area is properly supported and the install is planned correctly.
If you’re ordering an enclosed trailer with an AC unit, roof prep should be part of the build plan—not an afterthought.
Cooling performance depends on airflow. Your interior height, layout, and what you load inside can either help airflow—or block it.
A few simple planning rules that make a big difference:
Avoid placing tall cabinets directly where cold air needs to circulate
Leave room for airflow paths (especially in compact builds)
If you’ll work inside, consider extra interior height for comfort and usability
A/C is a major comfort upgrade—but it works even better when paired with the right build choices:
Ramp door vs barn doors (depending on whether you roll equipment in/out)
Side door placement for easy entry when the rear is blocked
Ventilation options (for moisture control and air exchange)
Interior lighting upgrades for safe loading or evening work
If you tell us your use case, we’ll guide the configuration so the trailer feels purposeful—not generic.
A/C-equipped enclosed trailers are popular because they support both comfort and protection in harsh temperatures. Common uses include:
Mobile workshop / contractor setup (tools, materials, job prep)
Race trailer / motorcycle hauling (better comfort while loading and at events)
Event support trailer (secure gear storage between stops)
Mobile inventory or deliveries (reducing heat exposure for sensitive items)
Service pros who want a cleaner, controlled environment inside the trailer
If you’ve ever opened a trailer in peak summer heat, you already know why A/C becomes a must-have.
Rooftop A/C setups are typically designed for standard AC power, and install considerations often include 115VAC power requirements.
Two common ways buyers plan power:
Shore power: plug in where power is available
Generator: for off-grid use when you need A/C away from hookups
If you’re using a generator, it’s important to plan for startup draw and realistic continuous operation.
These issues cause most buyer regret:
Skipping insulation and expecting A/C to “fix” the heat
Undersized power plans (weak generator, unsafe wiring, poor extension cords)
Parking in direct sun all day with no heat-management strategy
Layouts that block airflow and trap hot zones
A good A/C trailer build prevents these problems at the design stage.
When you order factory-direct, you get a trailer built around your use case—not a compromise. The difference is in the planning:
A/C choice matched to trailer size and expected conditions
Electrical package designed for safe, reliable operation
Insulation options to deliver real cooling performance
Practical layout guidance for airflow and daily usability
You’ll end up with a trailer that performs the way you expect—on day one.
To quote accurately, we only need a few details:
Trailer size (length + width)
Interior height (standard or extra height)
Door style (ramp or barn) + side door preference
A/C preference (13,500 BTU or 15,000 BTU; heat strip optional)
Electrical package needs (basic or expanded use)
Insulation (recommended)
Power plan (shore power, generator, or both)
Call, message, or request a quote and we’ll guide you to the right A/C + electrical + insulation combination based on how you’ll actually use the trailer.
It depends on trailer size, insulation, sun exposure, and how cool you want the interior to feel. 13,500 BTU fits many common builds, while 15,000 BTU is chosen for extra cooling headroom, larger interiors, or harsher conditions.
Yes. A/C packages commonly require an electric package so the unit runs safely and reliably with correct wiring and protection.
Not always required, but strongly recommended if you want the A/C upgrade to perform well. Insulation reduces heat gain and helps the trailer cool faster and stay stable once cooled.
In many builds, yes. Heat strip options are commonly offered with rooftop A/C packages and can help take the chill off in cooler months.
Both can work. Shore power is common when hookups are available, and a generator can work for off-grid use. The best setup depends on how you’ll use the trailer and what else you’ll run inside.
Many rooftop units use a standard-style opening commonly referenced as 14-1/4″ x 14-1/4″.
A/C installs require correct roof planning and support. If you’re ordering an A/C-ready trailer, roof prep should be addressed as part of the build plan—not left to guesswork later.Can I retrofit A/C later, or should I order it installed from the factory?
Retrofitting is possible in many cases, but ordering it installed from the start is often simpler because roof prep, electrical, and insulation can be designed together upfront.
