Chasing a refrigerant leak… but the system told us the real problem 👀

3 flashes on the board = sensor failure. Not a leak.

That’s a big difference—because now we’re not talking about replacing a coil, just swapping out a faulty sensor. Way smaller fix.

Still sucks it failed this early, but that’s exactly why warranties matter.

Moral of the story: read the codes before you start tearing things apart. 👇

This is why variable speed systems are a different game.

Throw it in frequency lock and it literally tells you everything—voltage, amps, all of it.
Right here we’ve got ~240V coming in and about 9.3 amps running. No guessing.

I’ve seen installs running low voltage like 228… and nobody catches it. That’s how you kill boards over time.

With systems like this, you don’t need gauges to get a quick picture—you just need to know how to read it.

Protect it with surge protection + voltage monitoring, because once that board goes… it’s not cheap.

Techs—are you trusting the data or still pulling tools every time? 👇

Most techs skip this… and it shows.

Variable speed systems won’t always run at full capacity—so if you’re not using frequency lock during startup, you’re basically guessing your readings.

Tonight it’s 83° and the system wants to run low… but how do you check pressures, amps, and performance like that? You don’t.

You’ve gotta force it to 100%. That’s called doing it right.

Real question is—how many installs never get properly commissioned? 👀👇

This one had me scratching my head 🤔

Wwhy is water shooting out the vent while it’s running and splashing back into the pan?

Techs in the comments—what’s causing this? 👇

Those service valves will tell you everything.

If they’re already leaking and you don’t catch it beforehand, once you connect and disconnect your hoses… now you’ve got no clue:
👉 Was it leaking before… or did I cause it?

Little bit of oil residue here — could be from past service, could be the start of a leak.

This is the stuff that separates guessing… from actually diagnosing.

Something’s not adding up here… 👀❄️

Suction line goes one way…
Liquid line goes another…
And the thermostat wire? Running with it too.

I’ve never seen a lineset split like this before. Normally, these run together for a reason — insulation, efficiency, and proper system performance.

When you see copper lines routed separately like this, it usually means one thing:
👉 Something was changed, patched, or rerouted along the way.

Now the question is… why? 🤔

Love it when homeowners happily pay you for the repair and send you home with cookies they’ve made.

Growing up in the Midwest, this was very the norm. Brings back memories.

They say it’s been “maintained”… but the system tells a different story 👀❄️

I’m looking at a 20-year-old unit with new parts thrown in — capacitors replaced, fan motor changed, lines reworked… clearly someone’s been here before.

But here’s the problem:
Maintenance isn’t just swapping parts or clearing a drain line.

No caps on the lines, signs of multiple repairs, and a system this old still struggling? That’s not maintenance — that’s patchwork.

At this age, every visit should answer one question:
👉 Are we fixing it… or just keeping it alive?

Let’s see what the pressures say.
