China makes 80% of all air conditioners in the world.  

I asked her if she had remembered to put the covers back on her window air conditioners.

I saw several window air conditioners in windows.

They could purchase window air conditioner units for around $100 each at Walmart, so that could be an option to stay cool.

It is working out pretty well all in all, since I am almost always on line even when I am on a 5 week bike trip across Europe, except on a long flight to Asia or Africa or on safari with no internet.No one will manage the way you want them to- just silly things like putting 2 little bottles of conditioner in the toiletry basket instead of one shampoo and one conditioner, or checking to see if some places in the yard were cleaned that might not be on the normal checklist but because of recent weather you think there might be a problem.

We keep portable heaters and portable AC units on hand for times when a furnace or air conditioner might stop working.

I have the furnace and air conditioner inspected every year by a local company.  

Against my advice, my friend is doing a "press to test" on withholding rent due to a broken air conditioner for the whole summer.

We are warning our guests of that, though.We have a mini-split inverter air conditioner/heater.  

Vacant houses are subject to getting the Air Conditioner Condenser ripped off.
