AC repair
A Memphis July finds every weakness a cooling system has, and it finds them all in the same week. When one quits, the useful question is not whether someone can come — it is what they will measure when they do, because ten minutes with gauges separates a forty-dollar afternoon from a four-figure one.
What a real service call covers
The electrical suspects first, because heat kills them first: the run capacitor measured against its rating, the contactor checked for pitting, the compressor’s draw read under load. Then the loop itself — refrigerant charge measured rather than assumed, with a temperature split across the coil to confirm what the gauges claim. Then the two things this city adds: the outdoor coil, inspected for the pollen and cottonwood that mat it every spring, and the condensate drain, which in Memphis humidity shuts down more systems than compressors do.
Where your equipment lives changes the visit. On a slab house the air handler is in the attic, so the drain pan, its float switch and the secondary pan all belong on the checklist — that is the difference between a no-cool afternoon and a ceiling repair. On a crawl-space house the ductwork underneath is worth a look at the same time, because damp air down there does slow damage to insulation and metal that nobody sees from inside.
Repair or replace, without the pressure
Ordinary wear is ordinary: capacitors, contactors, fan motors and drain switches are consumables on a machine that runs a long Memphis season. A compressor or coil failure is a different category — a large repair on a system whose every other component carries the same hours, facing another hundred-day summer the moment it is fixed. And on older equipment, the refrigerant itself can change the arithmetic before anyone touches the leak.
What protects you either way is a written finding: what failed, what was measured, what each path costs. A visit that ends with a number and no findings is a quote, not a diagnosis — and in a heat wave, when every shop’s phone is ringing, that written finding is also the only thing that makes a second opinion possible.
Quick answers
- Why did the AC quit during the hottest week?
- Because heat is load, and load finds the weak part. A tired capacitor, a matted coil or a charge drifting low all survive May and fail together in the first real heat wave — it is the most predictable failure date on the Memphis calendar.
- There is water on my ceiling and the AC stopped — related?
- Almost certainly. On slab-built houses the air handler sits in the attic and drains condensate through a small line; when it clogs, the pan backs up. A float switch stops the system before the ceiling pays for it — worth confirming you have one.
