The haboob is in your condenser.
A summer dust storm packs the fins of the outside unit with fine dust. The AC keeps running, but it has to work harder every day after.
Kestrel Air / After a dust storm
Why it matters
The outside unit gets rid of the heat your AC pulls out of the house, by blowing air across a coil of thin aluminum fins. Coat those fins in dust and the heat can’t get out. Pressures climb, the compressor runs hotter, and the bill goes up.
How to check yours
- Turn the system off at the thermostat and the disconnect by the unit.
- Look through the side grille at the fins. If they’re matted grey or brown, they’re clogged.
- Gently rinse from the inside out if you can reach, or from the outside with a garden hose on a gentle setting. Never a pressure washer: it folds the fins flat.
If the coil is packed with mud or cottonwood fluff, or you’re on a rooftop unit, that’s a $149 deep clean, and it’s included for Kestrel Club members every September.
Coil looks brown? We’ll rinse it.
