What equipment can FixGrid AI diagnose?

Residential appliances (refrigerators, washers, dryers, ovens, dishwashers, microwaves) and HVAC equipment — residential systems, commercial rooftop units, chillers, VRF, heat pumps, and refrigeration.

Which BMS / IoT protocols are supported?

BACnet/IP, Modbus TCP, Niagara N4 and Metasys are supported out of the box, with brand-specific connectors for Carrier ComfortLink, Daikin DIII-Net, JCI Metasys, and Mitsubishi M-NET.

Is FixGrid AI better than MeasureQuick or Bluon?

FixGrid AI combines live BMS/IoT telemetry, predictive failure modelling, and brand-specific error code libraries in a single AI-driven workflow — going beyond manual probe-based tools.

How much does it cost?

Basic AI diagnostics are free. A $29.99 DIY Pass unlocks the full step-by-step repair guide for a single appliance. Intelligence Packs start at $49 and run up to $199 for industrial verticals.

How accurate is the diagnosis?

Free basic diagnosis returns ranked causes from a rules engine. With the DIY Pass we cross-reference your exact model + serial against the brand's service-bulletin library for a precise, model-specific answer.

What if my fridge isn't a major brand?

Any brand works — even off-brand or commercial units. The AI falls back to category-level intelligence so you always get a useful answer.

Do I need the serial number?

Brand and model is enough to start. Adding the serial unlocks date-of-manufacture, recall notices, and revision-specific service bulletins.

Can FixGrid help me decide repair vs replace?

Yes — every diagnosis includes a likely-cost range and a repair-vs-replace recommendation based on the unit's age.
