Why we won't just recharge it
A sealed system does not consume refrigerant. If it is low, it escaped somewhere — a hose, an O-ring, the condenser, or the compressor shaft seal. Topping it up without fixing that gets you a few weeks of cold air and a repeat bill, and it vents refrigerant into the atmosphere. We would rather find the leak.
R-134a or R-1234yf?
Vehicles built from roughly 2015 onward increasingly use R-1234yf, which costs several times more than the older R-134a and needs different equipment. This is the single biggest variable in an A/C bill, and it is set by what your car came with — we will tell you which you have before quoting.
It's cold at speed but warm at idle
That usually points at airflow across the condenser rather than the refrigerant charge — often a failed cooling fan or a condenser packed with road debris. It is a genuinely different repair from a leak, and usually cheaper.
