I'm getting 4 hr dry times normally and I had a customer send pics that his carpet buckled in all 3 rooms.. no furniture moved around after cleaning.. and carpets were dry 100% in less than 6 hrs. It rained its ass off all day where we were. I've never had carpet buckle before in 33,000 jobs. I'm using much more powerful equipment. What causes this other than excessive humidity levels in the home.. I know overwetting can obviously be a factor.. but w a 6 hr dry time.. that cant be the issue.. any ideas how to explain this so customer doesnt complain
