Most home scans take about 60 minutes for a typical 2,000-3,000 sq ft home. Larger homes can take a bit longer.
Life happens, so if you need to pause partway through, no problem. Your scan saves automatically. Just open the app when you're ready to pick up where you left off.
Tips for a faster scan:
Walk through your home once before starting to plan your route.
Have your thermal camera connected and charged before you begin (see How do I use my thermal camera?).
Make sure there is at least a 10°F temperature difference between inside and outside (see When is the best time to scan?).
