I have a 1989 Chevy 1500 with no AC from factory how much would it be to add AC?

If your going to do the work and your planning on buying the parts at the bone yard then expect to spend around $1000.00 when its all said and done. Having it done by a shop? $2500 - $3500.

Agree with boholmark,keep the poor man ac it is eqiupped with, 55 window,s down.

The parts are surprisingly cheap...compressor $150, condenser $80 evap $80 but there is much much more to it than that...expansion valves, lines, mounting brackets, getting the condenser to fit in if front of radiator. getting the evap under the dash, cutting holes here and there, finding a way to get a BELT on compressor, controls, that's a lot of money to spend on a 1989. All the logistics give me a headache just thinking of that job. Anything is possible but it will cost more than the present value of the truck. I have no reason to doubt BohoMark's numbers...he is very knowledgeable, but seems low to me. Many hours of labor. This is just a typical generic system, click on it

Good morning gentlemen...we used to call it 255 A/C 2 windows down 55mph

Here is an idea....http://www.alibaba.com/showroom/portable-air-conditioner-for-cars.html

Im considering a roof air unit for my '89 G10, It had a Roof option from the factory so i know it can handle the weight plus ill use extra suppor bows.... My question is what size is appropriate..? my Van is already well insolated

Hey guys dont spend $1000 or $2000 on putting whole a/c unit just go on ebay and but you a under dash air conditioning universal unit its cheap and much easier to install
