Review on 15K BTU Ducted RV Air Conditioner With Heat Pump For Heating & Cooling - Quiet AC Unit For Camper, Motorhome, Trailer by Joe Glass

Read the reviews and did research before getting this. Installed today by a qualified repair shop. I upgraded to a 15000 thinking it would be a tad more powerful than the 13.5. The air coming out "seems" colder, but not impressed with the air flow. Remains to be seen if it can cool down at the same speed as my previous unit which had a higher air flow.Now here is the big problem for the lower stars: it is VERY loud inside my RV. Sounds like a diesel truck is outside. Not sure if this is because more sealant or something needs to be added. But the noise is completely unacceptable. Outside, it is incredibly quiet. So something is wrong.If I can figure out why it's so loud and fix it, it will go to 4 stars.Update 10-12-22: unit has stopped working. Fan goes on, but no compressor. Now need to go to a local shop immediately and see if they can fix it. Crap! It's only been a couple of weeks.
