fitting air conditioning
Discussion
I can speak here with some experience on air-conditioning as that is part of my job as a coolng & refrigeration systems engineer for a large motor company. Firstly, aircon does not work with the roof off, or the windows down. Secondly aircon is not just cold air - it is conditioned air . Which means you should be able to have a/c and heat. I believe this is not the case with TVR as the switch is at the full-cool position. I almost bought a 1993 4.3 with a/c but it actually put me off from buying it. Note this was an early R12 (Freon) refrigerant system which would be difficult (expensive) to service now. Don't bother, and save some money!

I've also been in convertible cars where aircon gives a nice cool breeze even with the roof off - again it would be cooler with the roof on, but it's as good as you would expect....
Agreed it's not energy efficient, but it does work.

quote:Thanks. I appreciate the difference between climate control and cooling. The main reason for the ac is I have started suffering from hayfever and driving with the roof down is about the worse thing you can do but I am not going to let it spoil my fun! So I either have cooling, no tvr or kill myself driving due to watery eyes & constant sneezing.

As a fellow sufferer - just drug yourself up to the eyeballs and no more sneezing, watery eyes etc. Works for me.
A/C does cool the feet however on a really hot day stuck in traffic the water temp can get a bit high and then turning the A/C off helps (the car not your feet). Annoying really.

I can speak here with some authority on air-conditioning...Firstly, aircon does not work with the roof offR...
So, RichB - on what authority do you speak?
I see you also drive a Volvo........! 
Perhaps I started my note wrong then - but I would still claim to be correct. Note that I said air conditioning - of course you will still get refrigerated air.

No Craig, a fundamental mistake. Air conditioning is more than just cold air. Yes of course the air from the vents will be cooler when you are driving the a/c system but you won't have the correct envoironment.
Stroppy sod aren't you Roger? Yes I have a Volvo, and a Griff and an Alfa Romeo and the roof comes off 2 out of the 3 and I don't give a toss about the in's and out's of the technicalities. fact is I get a nice blast of cold air out of the vents in the Alfa with the roof down which in 99% of people's books would mean the air-con is working. Sorry mate but if you come on here "speaking with authority" and waving fingers then expect some flack in return when people disagree. Oh and don't worry about being by the Volvo I think you'd find the T5 more than adequate, even has separate temp controls for passenger & driver on the the air-con or should I say climate control of is that the ECC? oh I don't give a shit - it certainly goes well enough

Damn the Laws of Physics! Repeal the Conservation of Energy Law right now.

Ooooooooh! - do I have a bite here? Now don't take it so personally RichB. So, you have three cars which are worth some wedge - probably because you're a Rich B ? Guess who works on Volvo aircon? Now, wind your neck in and have a saucer of milk. Remember, some days you learn nothing
p.s. - I bet that's you in the swimming cap in the photo?
I think we all get the point without being tooooo pedantic. You don't get conditioned air with the windows open/roof down. JUst cold air.
But we like the taste of fumes/petrol we griff/chim owners would just like to get chilly feet. Is the TVR A/C any good? I have sat in a couple of griff with AC supposed fitted and it only gave a slightly warm air flow (comapared to the usually very warm on cool setting)
Could be they both needed regassing
I was surpised that a retro fit is only 2K, as this is the same price as a TVR factory OEM fit, I woulld appreciate anyone who has this say if the think it is worth doing.
Personally I would let tvr do the it, because if there are any problems it 'should' be easier to pin the blame down
