I had the polar fox APU installed on my 2027 Freightliner for about two weeks now it definitely cools the truck down. I haven’t had a chance to use it in extreme heat, but I believe it’s Going to work just fine. The key trick to APU’s is cool your truck down first then start your apu! I had a great experience of getting it installed. Everybody is very knowledgeable of the unit no matter who I talk to. They had the answers to my questions. I also had it installed at the main place in Canton Ohio. It’s an all day Install thank you, Ryan and Sophia for making the process easy and say thanks to your installers. They were awesome.

We got Polar Fox electrical APU T-model installed on our truck this summer. We are happy with the system! First, the price is very affordable compared to other electric APU providers. Second, the installation was very clean and quick. We only stayed in hotel for one night! Third, I am happy with the lithium starting batteries that comes with the system which has 5 year manufacturing warranty. The A/C unit provides a good amount of cooling, and sometimes I have to turn it off at night, because it can be very cold! So far, we are happy with the decision to purchase the Polar Fox APU for our truck! No more idle at night! Yay! 😜

I have a Polar Fox Elitę 12V system installed this summer. When I am in Georgia, Arizona, mid 80 and low 90 and 100% humidity, I can get more than 10 hours run time, still have 20% of battery left! I love the batteries, I always leave my refrigerator running for 2.5 days, it only uses 20% the batteries. The system is running quiet, i get good sleep at night. The system has low maintenance, you only need to clean the ac filter once a year. While my friends WHO have the Diesel APU, they spend more than a thousand every time they visit the Dealer. All in all, I enjoy the system!

I just had the polar fox 10,000 BTU unit put on my truck! It works great ! The installation was very quick as well! Everyone there was very very helpful and nice ! If your even considering an apu this is by far the way to go ! We have 8 other diesel apu on our trucks not one works at all there nothing but problems! This unit says it will run 10 plus hrs on the battery I had 69% battery when I turned it on last night ran it all night kept it 66 degrees in my truck for 14hrs and when I turned it off I still had 29% battery after 14hrs of running! But everything about this unit are these people are great !!!

The team at Polar Fox installed a 24 volt apu system in my truck. I could'nt be happier with service and product. No more diesel apu for me! This unit is very quite. Air flow is amazing. As for run time, I haven't run the batteries dead on it yet

I had a Polar Fox electric A/C system installed on my truck, and I’m very happy with the result. The installation was done very professionally, clean, and well-organized. Everything was mounted neatly, the wiring and hoses were routed properly, and the overall layout looks very clean and thought out.

The system works great. It was about 32°C outside, and the truck stayed very comfortable inside. The biggest difference compared to a diesel APU is the quietness — no engine noise, no vibration, just comfortable cold air. It makes a huge difference when you are resting in the sleeper.

The team did an excellent job. You can tell they know what they are doing and care about the quality of their work. I really like how everything was installed and how the system performs. I would definitely recommend Polar Fox to other truck drivers looking for a clean and quiet electric A/C solution.

Thank you, Polar Fox, for the great work!
