Excellent Excellent SERVICE Excellent Excellent SERVICE! Any issue or question and they got right back to me....even a phone call too! AND The unit works GREAT! Easy installation with instructions provided. Perfect size/performance for my 144" Sprinter 2500! It's really "COOL" now! ;-)

The unit has no air filter The AC unit cools and operates well. The unit does not have an air filter. Running any AC unit without an air filter will eventually clog the evaporator coil with lint which will destroy the efficiency of the unit. The evaporator coil is wet from condensed air causing the lint to stick to the coil, reducing airflow and severely impacting the cooling. It is very hard and messy to clean an AC evaporator coil. The support technician advised me they are aware of this and working on a fix. Once filter issue is resolved the unit is worthy of the highest rating.

The air conditioner survived shipping… The air conditioner survived shipping ok, arrived undamaged. While the shipping box looks good the wood is very thin. The metal around the box and metal tabs you have to pry apart are micro thin and sharp as a razor. I only got a minor cut but I was cautious once I saw the danger. Unit is working OK. Velit employee Ben is very good at answering all my questions I email him.

Great Purchase - I recommend this product Most importantly: The heater is working great! Keeping us warm on cool nights. It pumps out significant heat. I live at an elevation >9000ft. So far, this unit is working great whether we’re heating the van at home or while traveling. Also important: Post purchase support was great. I broke the electrical connector that the unit ships with and they shipped me a replacement no questions. Highly recommend. Well worth it considering alternative gasoline units are 3-4 times the cost.

4kw heater Phenomenal little heater. Better than espar, webasto, etc. highly recommend. Operation is simple and easy. Dropping the gas tank is tricky, and removing the fuel pump apparatus is also a bit of work. But it’s worth knowing this thing won’t crap out mid-winter. Highly recommended. Was able to fit this under the passenger seat of a 2023 transit, and I was able to rotate the inverter so inverter also fits
