Default A/C in the Scion tC Gen1..

Is there any inexpensive way to help push colder air from the car? I get its a 4 banger but i was curious. I did some Googling with no real answers. People keep saying try
replacing the A/C unit but with the same unit which isn't going to do much IMO. I did have the stealership check it while under warranty and they claim its normal.


Just curious thanks.

no, but you can easily help the car stay cooler so the a/c has an easier job keeping the car cool. get a good quality tint job to help keep sunlight out, and close the shades for the sun roof and you'll cut the solar energy heating up the inside of the car, thus allowing the a/c to keep you cooler. also, put it on recirculate.

I haven't gone the tint route yet but i do use a windshield visor to block the majority of the sun.

Yeah tint makes a big difference. Mine meters 13% and I have no complaints about my a/c other than it being a power leech.

limo tint the rears and light tint in the front, use sunshade to block sun from the windshield often it is the only best solution! to say about the ac on the tC I would rather drive my civic lx then driving the tC.

Interesting article I found that some might find helpful.


The home mechanic, looking at a can or two of R12 or R134a, may think that government concern over refrigerant is overblown. However, CFCs like R12 have been found high in the atmosphere, where they destroy ozone (since CFCs have been regulated, the ever-widening holes in the ozone layer have been healing themselves). Likewise, a/c refrigerants have proven highly effective at trapping heat, increasing the possibility of man-made global warming; R134a is said to be 1,400 times as effective at trapping heat as carbon dioxide; a few leaks from a few cars would probably not have any serious impact, but there are an estimated (by the auto industry) 400 million mobile air conditioners out there.

Europe is planning to phase out R134a due to its relationship to global warming. Carbon dioxide is the current E.U. leader; it’s the least powerful greenhouse-gas, but it must work under very high pressure, and is less effective than engineered refrigerants. While new cars will use carbon dioxide, R134a will probably still be produced for older cars, avoiding the currently extravagant prices for R12.

One replacement under study, R152a, has heat-retaining power just 10% that of R134a, but is still a good refrigerant (unlike carbon dioxide). Another new refrigerant being developed by Dupont and Honeywell would be a “drop-in” substitute for R134a, but would trap less than 10% of the heat as carbon dioxide when in the atmosphere. No timeframe for availability is available yet.

There have been two major types of air conditioning refrigerant in North America: R12, "the old kind," and R134a-based, "the new kind." (R22 was used briefly as well in the early days.) Today’s air conditioners seem less reliable than the R-12 units of old, and repairs are very expensive as key parts are buried deeply in the car. Still, R12 had a clearly demonstrated link to holes in the ozone layer, with clearly dire effects for the future. R134a was adopted, and many say it was adopted because DuPont had a patent on it; Australia uses a cheaper and more efficient refrigerant system.

IMO you might be due for a refill, if not try looking for a better refrigerant http://www.jcwhitney.com/arctic-free.../p2011347.jcwx
