@Helen3 @Mary4068 - And they most certainly will. I had a case recently where one of the upstairs rooms was incredibly hot, more so than it ever should have been even with the air conditioning on in the summer heat. The guest alerted me to it and we had a duct work specialist come out who fixed the problem and then actually waited to see if the temperature in the room dropped.
There was some minor duct repair needed, but added bonus the guest had opened the window in 90 degree weather and never told anyone that. Had they not done that, there would really have been little difference in the room temperature.
Anyway, emergency repair work, checking on them to see if the room had cooled, standing by if it didn't...left a 4 star review. They didn't say anything negative in the public feedback, but in the private feedback (get this) they thought they were making a report directly to AirBNB and didn't realize the private feedback was going to me (they had never used AirBNB before apparently). The private feedback was full of complaints about how they had to go "back and forth" to get the air conditioning turned down (no mention of the repair work) and how I was a condescending host since I had originally asked them if the fan in the room was running and if the vent was blocked (common questions I ask if I hear the rooms are too hot).
So, no. If they are going to leave a bad review they will do it regardless of how nice you are or even what the truth of the situation may be.
