You know that moment when you’re parked in the Arizona sun in July, the rooftop AC is screaming like a jet engine, and the thermostat reads 88 degrees no matter what you do? Yeah. I lived that for two summers with the stock Dometic that came on my trailer. It blew cold air — technically. But it was loud enough to drown out conversation, cycled on and off like a haunted refrigerator, and drank battery power like it was free.
I finally got sick of it and swapped in the TURBRO Inverter 13.5K BTU unit with the heat pump. That was eight months and a full cross-country trip ago. Here’s the unfiltered truth about whether this thing is worth your $989.
First Impressions: This Thing Is Heavy, But So Is Everything
Let’s get the boring stuff out of the way. The box shows up and it’s big. Like, “did I accidentally order a mini fridge” big. The unit itself weighs around 85 pounds, which is about average for a rooftop AC. You’re gonna want a second person to help you muscle it onto the roof, especially if you’re working from a ladder. I’ve installed three rooftop units over the years, and this one wasn’t worse than any of them. The gasket seals well, the mounting bolts line up with standard 14 x 14-inch roof openings, and the included hardware is decent.
One thing I noticed immediately: the black shroud looks sharp. Not the cheap plastic gray you see on most RVs. It’s got a low-profile design that doesn’t make your rig look like a delivery truck. The LED atmosphere light on the underside is a nice touch too — it casts a soft blue glow inside the RV when you’re running it at night. It’s not gonna win any design awards, but it’s way better than the creepy white glow you get from most units.
The real test came when I fired it up. First thing you’ll notice: it’s quiet. Like, genuinely quiet. The compressor hums at a low pitch that fades into the background after about ten minutes. I measured it with a phone app — around 52 dB inside the RV, which is roughly the sound of a normal conversation. The old Dometic was hitting 68 dB on a good day. That’s not a small difference. That’s the difference between being able to hear your partner’s Netflix show and having to pause it every time the compressor kicked on.

Here’s the thing nobody tells you about standard RV air conditioners: they’re binary. The compressor is either running at 100% or it’s off. That means the temperature swings up and down, the unit short-cycles, and you’re constantly aware of the thing existing.
The TURBRO uses an inverter compressor, which is basically a variable-speed motor. Instead of slamming on and off, it ramps up when you need cooling and eases back when you’re close to the set temperature. The result is a steady, even temperature that doesn’t fluctuate more than a degree or two. I’m a light sleeper and I stopped waking up in the middle of the night because the unit was cycling. That alone is worth the upgrade.
But here’s the real benefit: power draw. A standard rooftop AC pulls around 13-15 amps when the compressor kicks in. That’s brutal on a 30-amp hookup, and it’s even worse if you’re running off a battery and inverter setup. The TURBRO’s inverter compressor starts soft — I measured it pulling around 8 amps on startup, settling to 5-6 amps during normal running. That means you can actually run it off a decent solar setup without tripping breakers. I run it off a 2000-watt inverter and a 200Ah lithium bank, and it’ll run for hours without killing the batteries. You’re not gonna do boondocking for days on end, but you can get through a night comfortably.
Heat Pump Mode: The Feature You Didn’t Know You Needed
I’ll be honest — I bought this for the cooling. The heat pump was a bonus I figured I’d never use. Then October rolled around and the nights started getting cold, and I realized I was running my propane furnace every single morning just to take the chill off the RV.
That furnace eats propane like a teenager eats pizza. A 20-pound tank lasts maybe three days if you’re running the furnace every morning and night. The TURBRO’s heat pump flips the refrigerant cycle and pulls heat from the outside air. It’s not a replacement for a furnace in freezing temperatures — the rated operating range goes down to about 30 degrees Fahrenheit — but for those cool mornings where it’s 40 degrees outside and you just want the place to be 68, it’s perfect.
And here’s the kicker: it’s basically free to run compared to propane. The heat pump only draws a few extra amps compared to cooling mode, and it’s not burning anything. I went from refilling my propane tank every week to making a 20-pound tank last a month. That’s a real, measurable savings. If you camp in the shoulder seasons, this feature alone pays for the difference between this unit and a cheaper cooling-only model.
I did notice the heat pump takes a while to really warm things up — you’re looking at 15-20 minutes to feel a solid temperature change in a 30-foot trailer. It’s not instant like a furnace. But once it gets there, it holds the temperature steady, again thanks to the inverter compressor. Just set it before you crawl into bed and you’ll wake up warm.
WiFi and Remote Control: The Good, The Bad, The Honestly Fine
I’m naturally suspicious of smart features on RV gear. They’re usually a gimmick that works for the first week and then forgets your phone’s Bluetooth pairing. The TURBRO’s WiFi app is… actually usable. You download the app, connect to the unit’s WiFi network, and then configure it to join your RV’s router or your hotspot. Setup took me about five minutes, which is better than most smart home devices I’ve dealt with.
The app lets you change temperature, switch between cooling and heating, set a timer, and adjust the fan speed. It’s not gonna win any awards for design, but it works reliably. I’ve used it from the driver’s seat while pulling into a campsite — I can start cooling the RV down while I’m still parking. That’s genuinely useful in August.
The remote control is standard fare. It does the basics, and the LED display on the ceiling unit shows the current temperature and mode. One thing I’ll note: the remote is a little cheap-feeling. The buttons are mushy and the range is mediocre — you have to point it directly at the unit. Not a dealbreaker, but don’t expect premium build quality.
The LED atmosphere light is controlled from the app or remote too. It’s got a few color options and brightness levels. I set mine to a dim blue at night and it’s become a nice ambient light for reading. It’s not a reason to buy the unit, but it’s a thoughtful touch.
Real-World Cooling Performance: The Numbers That Matter
I ran this unit through a Phoenix summer where the daytime highs hit 112 degrees. My trailer is a 26-foot bunkhouse with a slide-out, so there’s a decent amount of space to condition. Here’s what I found: the TURBRO drops the interior temperature about 20 degrees from ambient in the first hour of running. So on a 105-degree day, I’m looking at 85 degrees inside after 60 minutes. That’s not bad for a non-ducted rooftop unit.
The trick is running it on the highest fan speed during the hottest part of the day, then switching to auto fan once the sun goes down. The unit has three fan speeds plus auto, and the auto setting does a good job of ramping the fan down when you’re close to the setpoint. It’s not as effective as a ducted system for evenly distributing air across a large RV, but for a single-zone setup, it holds up.
One thing I noticed: the intake filter is accessible from inside the RV. You pop the ceiling grille off, slide out the filter, and rinse it in the sink. That’s a huge upgrade from units where you have to climb on the roof to service the filter. And speaking of filters, I’ve been using the RV A/C Filters Replacement, 16 x 40 x 1/4 Inches RV Air Conditioner Replacement Filters as spares when I’m on long trips. They cut to size easily and keep the dust out of the coils.
The Noise Level: Numbers Don’t Lie See Today’s Deal on Amazon
I’m a stickler for quiet. I’ve slept under cheap rooftop units that sounded like a helicopter landing, and it ruins the whole camping experience. The TURBRO manufacturer claims 42 dB, which is marketing speak for “whisper quiet.” In reality, at full compressor speed and high fan, I measured around 50 dB from directly under the unit. At night, when the inverter ramps down to maintain temperature, it drops to around 35 dB. That’s genuinely library-quiet.
The biggest surprise is how the sound changes character. Standard units have that harsh, mechanical drone that pierces through walls. The TURBRO has a lower, softer hum that’s almost white noise. I’ve fallen asleep to it running many nights. My wife, who is the world’s lightest sleeper, hasn’t complained once. That’s the highest endorsement I can give.
What I Don’t Like: Being Fair
Nothing’s perfect, and this unit has a few quirks. First, the installation instructions are mediocre. They’re written in broken English and the diagrams are small and unclear. If you’ve installed an RV AC before, you’ll be fine. If you haven’t, find a YouTube video before you start. It’s not hard, but the instructions won’t help you much.
Second, the WiFi setup requires your phone to be on the same 2.4GHz network as the unit. Most modern phones default to 5GHz, so you have to switch networks in your phone settings before the app will find the unit. It’s a minor annoyance that took me a few tries to figure out.
Third, the unit is not a true low-profile design. It’s about 12 inches tall on the roof, which is a bit taller than some of the ultra-low-profile units from other brands. If you’re worried about clearance for your RV cover or parking in a garage, measure carefully before you buy.
And one more thing: the LED display on the ceiling unit is bright. Like, “lights up the whole bedroom” bright. I had to cover it with a piece of electrical tape at night because it was keeping me awake. There’s a dim setting in the app, but it’s still noticeable. Minor quibble, but it’s the kind of thing you only notice after you own the unit for a week.
Power Consumption: The Real Cost of Comfort
I plugged a Kill-A-Watt meter into my shore power setup to track actual usage. Here’s the honest breakdown: at full cooling on a hot day, the unit draws about 950 watts. That’s roughly 8 amps on a 120-volt circuit. When the inverter ramps down to maintain temperature, it drops to around 400-500 watts. Over a 24-hour period with the thermostat set to 72 degrees in 90-degree weather, I measured an average draw of about 550 watts per hour. That’s 13.2 kilowatt-hours per day.
At the average US electricity rate of 16 cents per kilowatt-hour, that’s about $2.11 per day to run it. Compare that to a standard rooftop unit that runs at 1500 watts continuously — about 36 kilowatt-hours per day, or $5.76. The TURBRO saves you roughly $3.50 per day on electricity. Over a 30-day camping season, that’s $105. Over a year of full-time living, it’s over $1,200. The unit pays for itself in less than a year if you’re a full-timer. That math is hard to argue with.
Is It Worth $989? Here’s My Honest Take
Look, you can buy a standard rooftop AC for $600. It’ll cool your RV, but it’ll be loud, inefficient, and you’ll hate it every time you turn it on. The TURBRO costs $989 and delivers three things the cheap units can’t: quiet operation, significant energy savings, and a heat pump that saves you money on propane.
If you camp in mild climates and don’t mind the noise, save your money and buy the cheap unit. But if you camp in the South or Southwest, if you’re a full-timer, or if you just value your sleep, the TURBRO is worth every penny. I’ve been running mine for eight months and it hasn’t skipped a beat. No leaks, no weird noises, no compressor failures. It just works.
If you pick one up through the links here, I might get a small cut — doesn’t cost you extra and it helps keep the lights on.
I’ll say this: I considered a mini split for my RV instead. I’ve reviewed the YITAHOME 18000 BTU Mini Split AC/Heating System and the Rellytech 11500 BTU Mini Split, and both are excellent if you can deal with mounting a unit on the side of your trailer and running a line set. But they’re more expensive, more complicated to install, and take up interior wall space. The TURBRO is a drop-in replacement that took me an afternoon to install. For most people, that’s the right call. See Today’s Deal on Amazon
The TURBRO Inverter 13.5K isn’t cheap. But it’s the difference between tolerating your RV’s climate control and actually enjoying it. I stopped dreading hot days. I stopped waking up in a sweat. I stopped refilling propane every week. That’s the review. That’s the story. That’s what you’re paying for.
