A/C proper usage

[oj88]

Been using Air Spencer for 4-5 years on my 6 y/o car. When I had the evaporator core cleaned last year, the shop said, after doing an ocular, that it wasn't necessary (but I had it cleaned and reloaded with refrigerant anyway as a preventive measure). It had none/zero of those gelatin-like gunk. It was just a little dusty, which was to be expected on my then 5 y/o car.

I think what really matters here is whether the car is equipped with a cabin air filter or not. If it did, the cabin filter would've been able to capture (by my own estimation) more than 95% of air particulates.

If you regularly clean your home A/C's filter, you'll realize how helpful the filter is in prolonging the service interval of doing a complete A/C general cleaning. If it weren't for the filter, you'll be taking apart and hosing down the A/C in the garage every month or so.
