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.

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

Diesel Heater Upgrade I just replaced my diesel heater with the Velit Gasoline Heater, it is definitely an upgrade. I no longer have to carry diesel and the fuel pump tick is not noticeable. I also tested the temperature control that shuts off the heater at 3 degrees past the set point and starts again at 3 degrees below the set point. I would recommend this heater for any RV that runs on gasoline.

Pleased with Velit 12v RV AC Velit 12v RV AC shipped fast and so far very pleased with it. Draw is around 30amp/hr. Turbo is around 40amp/hr. No fuss install into standard AC opening. Easily keeps my converted ambulance cool. Quiet enough to sleep with it 5 feet above the bed. Generic AC remote is a bit annoying with buttons that don't apply but since it is easily within reach I change settings directly on the unit.

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.
