Compressor Discharge vs Outdoor Air
Loading…
usual middleusual rangeuncommonraredots = individual readings, last 14 days
The temperature of the hot gas leaving the compressor, against how warm it is
outside. It climbs with outdoor temperature because the system has to reject heat into hotter air
— that is normal. The shaded band is what is usual for this unit at that outdoor
temperature, measured from its own history. Above the band means the compressor is working
harder than it should for the conditions; it does not by itself say why.
Compressor Suction vs Outdoor Air · corrected to a 70°F room
Loading…
usual middleusual rangeuncommonraredots = individual readings, last 14 days
The temperature of the cold gas returning to the compressor. It tracks outdoor
temperature more loosely than discharge does, because it also follows how much heat the building is
putting into the air — so expect a wider band. Outdoor temperature here is reconstructed from
the refrigerant circuit, since the outdoor probe on this unit sits in the sun and reads about 23°F
high.
usual middleusual rangeuncommonraredots = individual readings, last 14 days
Heat rejected into the airstream, against outdoor temperature. The shaded band is the
usual range at each temperature and the line is the middle of it, both measured from
this unit. The band falls as it gets hotter because a condenser can only shed so much
heat when the outside air is nearly as warm as the coil — that is physics, not a fault.
Only a reading below the band matters; above it means it is rejecting heat better than
usual for the conditions.
Expected supply is built from outdoor air: the unit's own refrigerant readings, checked each night against the outdoor probe. Room temperature is tracked separately. Crews sometimes cool the room with other units (doors open, extra fans), so a trend is only reported when the outdoor-air view and the room-temperature view agree. Measured drifting above expected = the unit losing capacity.
The refrigerant line leaving the indoor coil. If the coil runs too cold, moisture on it can ice over and block airflow. This shows how much margin there is and which way it is heading.

Caution line is provisional until a technician measures refrigerant superheat on site; until then this panel judges margin against 32°F only.
Cooling Δ vs Outdoor Air
Loading…
usual middleusual rangeuncommonraredots = individual readings, last 14 days
How much colder the air gets as it passes through the unit, against how warm it is
outside. The shaded band is what is normal for this unit at that outdoor temperature, measured
from its own history. It slopes downward because every air conditioner cools less as it gets hotter
outside — that is physics, not a fault. A reading inside the band is ordinary; only a reading
below it is worth attention.
Supply Air vs Outdoor Air · corrected to a 70°F room
Loading…
usual middleusual rangeuncommonraredots = individual readings, last 14 days
The air leaving the vents, adjusted to what it would be with the server room at 70°F,
so a cool room does not look like a fault. It rises with outdoor temperature for the same reason the
cooling Δ falls. Only above the band is a concern: the unit is not delivering air as cold as it
usually does for these conditions. Colder than usual is shown but not flagged.

Component Testing
Capacitors · measured µF from voltage & current
With the unit running, measure the AC voltage across the capacitor terminals, and clamp an ammeter on one capacitor lead to read its current. Enter the nameplate rating and your two readings, then calculate. Formula: µF = current ÷ (2π × frequency × voltage).
