Saihisday 12V Car Truck Under Dash, A/C Air Conditioning Evaporator Assembly, Under-Dash A/C Heat + Cool Unit, 3 Speed 6 Ports for Car Truck

Works good. I’m using it with a small SD5H09 compressor & a relatively small condenser & it will make you shiver in the cab of my 1970 c10 pickup

I've bought 2 of these for large dump trucks and these units are AWESOME. I understand that they don't have a blend door from hot to cold so for some people this may be a hindrance. However, I was buying reddit a/c units and those have climbed far out of the range of reality in price. Note that I don't use the heat side of this. I just buy it for the a/c purpose. So I don't even have heater hoses hooked up. But I decided to try one of these to see how well they work and I couldn't believe the performance once it was hooked up. ICE COLD!!!. I'll never buy another reddot. The reddots are up to like $800 now and this unit performs just as well for $100. I worked in 90 degree weather yesterday and I have to keep turning this thing down at times because I kept getting cold with it. If I had a complaint, it would be that I have to mount the knob controls somewhere in my truck and that they're not made actually in the unit. Or that the vents aren't directional and adjustable for directing the air flow. But for $100, it's really not possible to have a complaint. Now for the people who may want to hook up the heater hoses and have the full function of the hot and cold, you would have to put a shutoff valve in line with your heater hoses so that when you run your a/c it isn't trying to produce internal heat and effect the a/c performance. Not a big deal though. You already have to run heater core hoses to it. Just put a ball shutoff valve in line with them. Again 100 plus rating with me and I've been running these for a year. I will be buying many more to install in all of my old classic vehicles for a/c. One last note, I see someone else reviewed that the compressor isn't built in and they didn't like that. It's an aftermarket ADD on A/C and heat unit. You still will have to install a compressor, condenser, and a dryer bottle on your vehicle, new lines and charge with oil and freon. That's how these are built.

Works too good... My 5.9 cummins stays cold when this thing is running but it does keep the cab warm... Least for me on a long drive it's almost uncomfortably warm lol didn't hook up the a/c as the a/c in the truck works fine... The heater core in the truck is out, replaced it once and it took me 2 days because you got to hit the entire interior of the cab to do it... This works well for the $$

Not having a way to separate hot air from cold air that’s the only thing I dislike other than that unit is of good quality the switches are going to be hard to mount given that they have no mounting brackets

Outa the box. Fan squeal loud. Grinding. Junk. Sad
