Did rain cause my new window air conditioner to make a spattering noise or was it normal operation of the unit?
I live in an apartment and had to ditch my portable air conditioner due to the vibration bothering my neighbors. Yesterday I bought and installed a new Frigidaire 6,500 BTU unit I got at Lowe's. It was working great until about 5:30am this morning when it started making a sputtering/spattering/popping noise every few seconds until I turned it off at 7am. It was not that loud but just enough to keep me awake.
After a little research it seems like the sound was from water bouncing off of the fan blades. I read that newer units use the fan to splash water onto the coils to increase efficiency (here)
. I am worried that the sound might be part of the normal operation as I know condensers drip water. If that is the case, I will have to get a different unit.
However, it was raining this morning (although I'm not sure if the rain started at the same time the sound started as I didn't notice the rain until I left the house at 8am for work) and I think maybe the rain was the source of the water hitting the fan.
My dilemma is that I can't afford to have another sleepless night. I am willing to go get a different model and install it tonight but I don't know if that will make a difference. Does anyone have any experience with this that can weigh in? Do newer window units make that sound all the time or is the rain the likely problem?
Thanks to anyone who can offer any insight!
