Callback prevention starts with what you do on every single maintenance visit — and right now, drain lines are the number one issue driving callbacks for HVAC tech in the field.
Don't just clean the drain. Look at the entire drain layout. Can you improve it? Can you enhance the water flow while you're already there? Every tech needs to ask that question on every call — whether it's a maintenance, a coil repair, or a service visit.
The other thing every technician knows but sometimes skips? Detailed notes and readings. Document everything — flow switches, pressures, temperatures, MeasureQuick screenshots, photos of the amp draw on the compressor. If you checked it, notate it. Tell the story of the system.
Here's why that matters: a tech recently did two maintenance visits before two compressors failed. The complaint came in hard. But because his write-up was thorough — pressures, temperatures, MeasureQuick data, photos — there was visual proof the system was running correctly at the time of the visit. That documentation backed him up completely with the property manager.
Tips like that don't just protect the customer relationship — they protect you. Good, honest techs deserve to be backed up, and when the notes and photos are there, that backup is easy.
