From Reactive Repairs to Proactive System Management. Every major HVAC breakdown starts as a small performance change — a rise in static pressure, a drop in Delta‑T, or a compressor pulling just a few extra amps. AirSenz sensors detect those signals early, turning potential breakdowns into simple maintenance tasks.
1) Rising Static Pressure
A clogged filter or collapsed return duct increases static pressure. When it exceeds 0.7 inWC, airflow drops and the system strains.
- AirSenz detects: static pressure trends rising over 48 hours.
- Action: replace filters and check return ductwork before airflow loss becomes coil icing.
2) Falling Delta‑T
A healthy cooling system shows a 17–20 °F supply/return temperature difference.
- AirSenz detects: Delta‑T dropping below 15 °F.
- Action: inspect coil cleanliness, verify charge, and check fan speed or damper position.
3) Compressor Over‑Amperage
Compressor amperage slowly climbs as charge or airflow decreases.
- AirSenz detects: amps trending 10% above baseline.
- Action: clean outdoor coil, verify charge, and check contactor or capacitor condition.
4) High Head Pressure
High discharge pressure indicates coil blockage or overcharge.
- AirSenz detects: discharge > 400 psig (R‑410A).
- Action: clean coil, verify ambient temp vs. saturation pressure.
5) Low Suction Pressure
Low suction suggests restricted airflow or undercharge.
- AirSenz detects: suction < 100 psig (R‑410A).
- Action: inspect air filter, evaporator coil, and refrigerant levels.
Conclusion
When your system “feels fine,” sensors are already watching for early warning signs. With AirSenz, every degree, amp, and inch of static pressure tells a story—before you need an emergency call.
