Yes – many folding campers come with built-in cooling systems, or at least the option to add one. Some include rooftop setups from the factory, others rely on portable models that can be installed after purchase. Either way, if you’re planning to stay anywhere around southern Alberta during July, some kind of cooling is probably a good idea.

Summer highs here tend to hover around 24 to 28°C, but the sun can make it feel warmer inside a canvas-sided shelter. Without insulation or proper airflow, it doesn’t take long before sleeping becomes uncomfortable. And if you’re parked without shade? That tented interior can turn into a greenhouse by late afternoon. We’ve had calls from campers who lasted two nights before coming back into town asking about small-scale cooling setups.

There’s no one-size-fits-all answer. Some owners prefer portable freestanding units because they’re easier to move or store in winter. Others go for rooftop-mounted compressors that offer more power but need professional installation. Each setup has trade-offs – cost, power draw, weight. And, frankly, it depends how long you’re staying out, how much power you can access, and how sensitive you are to heat.

We usually suggest starting with a simple plug-in model if your camper doesn’t already include something. They’re affordable and low-risk. If it turns out you’re using it more than expected, that’s when it might make sense to upgrade to a permanent solution. But don’t assume you’ll get by without anything at all – especially if kids or pets are involved.

What Types of Air Conditioning Units Are Commonly Installed in Pop Up Trailers in Calgary

For smaller recreational setups, rooftop-mounted units are the most reliable option – but they’re not always the easiest to add after purchase. These systems are typically built into the hard roof of the shelter at the factory. They work well, especially if you’re connected to shore power, and they’re strong enough to handle heat spikes during mid-July. Brands like Dometic and Coleman are popular choices. Most of these run between 9,000 and 13,500 BTUs.

Portable Units

If the setup didn’t include anything from the beginning, many owners turn to compact stand-alone units. Some use vented models with a hose that runs out a zippered window flap. It’s not elegant, but it works. Others go with evaporative coolers, though those aren’t always reliable during humid weeks – and we do get some of those in July and August. These portables usually pull 800 to 1,200 watts, which is manageable for most small generators or campground hookups. One customer told us he ran his off a 2,000-watt inverter without issue, but wouldn’t recommend it for overnight use without battery backup.

Under-Bench or Window-Mounted Options

These are rare, but they do exist. A few owners have modified their setups to accommodate smaller window-style machines. Usually this means cutting or adapting part of the bench or wall frame. Not everyone’s comfortable doing that, and we don’t typically recommend it unless you’re already planning major changes. They’re heavier, louder, and draw more power. But if you need something stronger and don’t mind the extra work, it’s doable. We’ve helped with a couple of these installs – usually it’s someone staying in the mountains for weeks at a time who just wants something a bit more stable.

We usually recommend starting with something that doesn’t involve structural changes. Try it out. If you’re not getting the results you need, then it might be worth going further. But for many casual campers, a basic portable unit is more than enough.

How Calgary’s Summer Climate Affects the Need for AC in Pop Up Trailers

If you’re staying in a fold-out camper around July or August, some form of cooling system is pretty much a necessity – especially if you’re parked anywhere without natural shade. Midday highs often hit 26°C to 30°C. On paper, that doesn’t sound extreme, but inside a canvas-based setup, it feels a lot warmer. There’s very little insulation, and once direct sun hits the roof or side panels, the temperature inside can jump fast – easily 8 to 10 degrees hotter than outside.

Nights are cooler, yes. Some mornings drop below 12°C. But the real discomfort shows up late afternoon through early evening. That’s usually the time when the interior heat has peaked and airflow drops off. Cross-ventilation helps a bit, but it’s not enough during a still, bright day. I’ve had neighbours at Bow Valley pack up early just because their unit felt like a greenhouse by 4 p.m.

Humidity and Weather Shifts

What complicates things is how unpredictable the weather can be. A dry week might lull you into thinking you don’t need anything beyond a fan. But then a humid front moves in, or smoke from wildfires blocks out the breeze, and suddenly the inside air feels stagnant. Even if you’re up in Kananaskis or out by Ghost Lake – anywhere that usually gets wind – conditions can shift within hours. That’s when most people regret skipping a cooling setup.

Short Trips vs Longer Stays

If you’re out for just a weekend, you might get away with minimal gear. Crack the panels open at night, run a fan, maybe cool off with a wet cloth if needed. But anything longer than three days? That’s where discomfort builds. For extended stays – especially in July – a proper cooling unit is less about luxury and more about making the trip bearable. Less sweating, better sleep, fewer arguments by day three. It’s not just about heat; it’s how relentless it feels without relief.

Can You Retrofit a Pop Up Trailer in Calgary With an AC Unit and What Does It Cost

Yes, you can. It just depends how much you’re willing to modify and spend. The simplest upgrade involves using a portable unit. These don’t require any permanent changes and can usually be vented through a zippered flap or small side window. Most models cost between $300 and $600, depending on cooling capacity. You’ll also need to think about power – a 1,200-watt draw might seem fine until you try running it off a limited campsite hookup alongside a fridge or microwave.

For something built in – rooftop or wall-mounted – expect a more involved process. You’re looking at structural changes, plus electrical upgrades in many cases. Labour costs can easily run $500 to $1,000 depending on how clean you want the install to be. The units themselves range from $1,200 to $2,500. Some people go the DIY route, cutting into the roof or building a custom frame. It’s doable, but mistakes are expensive, especially if water leaks in later. We’ve seen a few rough installs where insulation was missed or duct tape became a permanent fix. Doesn’t end well.

Window and Bench-Mount Setups

These are less common but still an option. You can modify a lower side wall to fit a compact window-style unit. It requires cutting, bracing, and sealing – so not for beginners. The total project might fall in the $800–$1,500 range, depending on whether you handle it yourself or bring someone in. We’ve helped a couple customers with this, mostly those using their units for extended stays – places like Bragg Creek or Water Valley where they’re plugged in for weeks at a time and need something sturdier.

In general, if you’re only out a few weekends each summer, go with a standalone. But if it’s something you’ll be using heavily through July and August, and especially if you’re travelling with kids or pets, a permanent setup starts to make more sense – even with the upfront cost.
