Intermittent HVAC faults love hiding between service visits. A data logger captures the full story over time—temperature, humidity and cycling—so you can prove when the problem happens, choose the right follow-up test, and show clear “before and after” results without over-claiming.
Thermal imaging can save hours on HVAC fault-finding—if you don’t get tricked by shiny metal, sun load, wind, or wet surfaces. This guide shows what a thermal camera really measures, the most useful HVAC use cases, the common false-reading traps, and a repeatable “scan, confirm, decide” workflow for split systems and commercial gear—plus how to report results without over-claiming.
Static pressure is the quiet number behind noisy ducts, weak rooms, and coil icing. This guide shows how to use a manometer to find restrictions fast—where to test, how to read the patterns, and how to prove the fix with airflow checks.
A clamp meter is one of the quickest ways to work out why an HVAC system won’t start, keeps tripping, or runs hot. In this guide, we’ll walk through the most useful checks—amps, inrush, voltage drop, capacitors and fan motors—plus the simple habits that stop wrong calls and repeat visits.
