In copper tubing. Smaller than a pinhead. Sitting in a coil that had been running in that house for eleven years, leaking refrigerant slowly enough that every summer the system lost a little more of its ability to cool, and nobody found it because nobody...

But a refrigerant charge is a measurement, not a diagnosis. If a system needs refrigerant every summer, it's leaking. And if it's leaking and...

She hadn't called her son. He'd called her — a Tuesday evening check-in, noticed she sounded off, asked about the heat. She'd said it was fine. He'd asked again. She'd said she was managing.

He wasn't effusive about it. Just mentioned it, the way you...

The tablet was propped against a pillow, the volume low, and she didn't look up when we came in.

Found the component that was misbehaving, replaced it or reset it, called the job done. The limit switch tripped again within a few weeks...

Sometimes the right one — systems can lose a small amount of refrigerant over many years and a charge gets them back where they need to be. But refrigerant doesn't evaporate. If a system is consistently low, something is leaking. Topping it off and leaving is...

Not a repair. Just the annual check — the one she books every year in late spring, before the heat arrives and she needs the system to actually work.

Things break. Equipment ages, parts wear, filters clog, capacitors drift.

Not connected to anything. Not failed — never connected.
