Real-World Testing: Putting DOMETIC Penguin II 13.5 Upper Unit to the Test

First Use Experience

My testing ground was my own 2018 travel trailer, parked at a campsite experiencing a typical mid-summer heatwave. I installed the upper unit myself, a process that, while requiring basic RV electrical and sealing knowledge, was fairly manageable. The unit immediately integrated with my existing ductwork, a crucial aspect for a ducted system.

During its initial run, it performed admirably in temperatures soaring into the high 90s Fahrenheit. It managed to bring the interior down to a comfortable 72 degrees Fahrenheit within a reasonable timeframe, a feat my old unit struggled with. The sound level was also noticeably lower than expected, a welcome surprise in the quiet campground setting.

The ease of use was exceptional; once powered on and connected to the thermostat (which was purchased separately, as noted), it simply worked. There was no complex setup or calibration needed beyond ensuring the thermostat settings were correct for heating or cooling.

One minor surprise was the slight draft I felt immediately around the edge of the unit when it was actively cooling, though this dissipated once the RV fully stabilized in temperature. It was more of an initial sensation than an ongoing issue.

Extended Use & Reliability

After several weeks of continuous use, including a week-long trip through variable mountain weather, the DOMETIC Penguin II 13.5 Upper Unit has proven its mettle. It’s been subjected to constant cycling between heating and cooling as ambient temperatures fluctuated, performing without a single hiccup. The unit has been exposed to moderate dust from campsite roads and the occasional light rain shower during setup, and it shows no signs of degradation.

Durability seems to be a strong suit. The exterior casing has resisted minor bumps from overhanging branches without any visible damage or performance compromise. There are no cracks, no stiffness in the fan housing, and importantly, no noticeable drop in cooling or heating efficiency.

Maintenance has been refreshingly simple. A quick dusting of the exterior and ensuring the air intake vents are clear of debris is all that’s required. For more in-depth cleaning, a simple panel removal allows access to the fan blades and coils, which are easily wiped down. I haven’t had to worry about any complex internal upkeep, which is a massive plus for an RV component.

Compared to previous RV AC units I’ve dealt with, this heat pump feels significantly more robust and less prone to the common issues of fluctuating performance or premature failure. It strikes a good balance between the brute force of some higher-end commercial units and the often underwhelming performance of budget RV appliances.
