Blower Motor & Fan Repair
A blower that hums but doesn't spin, or one that's pulling excess amperage, gets tested under load, not just visually inspected. Techs handling blower motor & fan repair carry the specific parts and tools this job calls for, not a generic kit.
Circuit Board & Control Diagnostics
A blown board is sometimes a symptom of a bigger electrical issue we'll flag. Techs handling circuit board & control diagnostics carry the specific parts and tools this job calls for, not a generic kit.
Thermostat & Wiring Troubleshooting
Short cycling, systems that won't call for heat or cool, or a blank thermostat screen often trace back to a wiring fault rather than the unit itself. This is one of the most requested HVAC repair calls we get across Northfield, IL.
