Everything replaced but still hot air

[steve4578]

hi everyone,
so i bought a 1996 explorer from my cousin and its in the best condition for its mileage .. the problem im having is the ac is hot.. before i got it, the condenser, compressor and another ac component were replaced.. but it still blows hot air.. it will blow cold air if its recharged but a week will go by and it will be warm again.. i don't want to bring it to a mechanic because it would too much, so i came here.. if anyone knows what could be the problem or how to fix it, it would be greatly appreciated.
thanks
steve

If it constantly needs freon there is a leak somewhere. There are several ways to determine leaks, from halogen leak detectors to adding dye to the system. The leak could be anywhere.
