When the AC quits in a Florida summer you want a straight answer today. We measure vent temperature, pressures, and airflow, then name the part that's at fault.
Warm air has three possible homes: refrigerant, electrical, or airflow. The whole job of this visit is finding out which one you're in before anybody spends money, because the work on those three paths has almost nothing in common.
We start with the measurement everything else hangs on: vent temperature against ambient. What counts as good in Central Florida in August isn't what counts as good in January, and a system running well below outside air is telling a different story than one barely beating it. Gauge readings then show how the refrigerant is behaving, whether the charge is short, and whether the pressure pattern points at a restriction instead of a loss.
Next is the electrical side. Does the compressor actually engage, and if it doesn't, is that a failure or a switch correctly refusing to let it run? On a lot of cars that single distinction is the entire diagnosis. A leak detection pass follows when the pressures call for one.
Airflow is the part people forget. Plenty of "the AC is broken" calls turn out to be a blend door stuck on the heat side, a blower that's lost speeds, or a cabin filter that hasn't moved much air in years. Cold refrigerant does nothing for you if it can't reach the vents.
You leave knowing which side of the system is at fault and which specific part, with inspection photos sent to your phone so you can see what we saw. And we get it, in this heat you want it fixed today. That's a good argument for measuring first, not for skipping it.
Our experts diagnose and resolve any issue.
Usually airflow across the condenser: a cooling fan that isn't coming on, or something packed against the condenser face. At speed the road does the fan's job for it.
Almost always a blend door or its actuator rather than refrigerant. Two temperatures at once means the cold is getting made and then misrouted on the way to you.
A blower losing speeds, a plugged cabin filter, or a leak in the case. Nothing wrong on the refrigerant side at all, which is exactly why airflow gets checked before anything expensive gets recommended.
Could be the compressor, could be a switch doing its job because pressure is out of range, could be a signal that never reaches it. Same symptom, three very different repairs, and the engagement check is what sorts them.
Moisture sitting in the evaporator case, usually a drain or airflow problem rather than a cooling problem. Different job from a cooling complaint, so it's worth diagnosing on its own terms.

Most AC diagnostics are a same-visit answer, since vent temperature, pressures, compressor engagement, and airflow all get checked in one sitting. The thing that takes longer is a leak small enough that it needs time to reveal itself. We'll tell you which of those you have before you head out.
Yes, and that's the easier version of this problem. A system that's partly working still gives readings we can interpret, and it usually has a smaller repair in front of it than one that's completely dead. Waiting until it quits entirely rarely makes the job cheaper.
If you can, yes. Drive it the way you normally would with the AC on so the system arrives in the state you're complaining about. A car that shows up cold and switched off takes longer to read, and a warm running system is closer to real conditions anyway.
Which side of the system is at fault, refrigerant, electrical, or airflow, then the specific part and the measurements behind that call, with photos of what we found. If more than one thing is wrong, you'll see them listed separately instead of lumped into one number.
Usually, because the answer often isn't the expensive part. Blend doors, blowers, fans, switches, and connections account for a fair share of warm-air complaints on older vehicles. You won't know which one you've got until somebody measures it.
