I recently had a house in escrow and the the air conditioner condenser was blowing a fuse and we had to replace all the baseboards on the first floor.

I would tell them it is what it is and they are welcome to supplement the air conditioner with portable A/C or window units.

My checklist says, tenant wishes to use "fill in blank" left by previous tenant.BTW, nobody works on window air conditioners, when you can buy a new one at Best Buy for $99 

@Tom CamardaYou can get a portable air conditioner/heat pump that is rated for 400-500 square feet for $250:http://www.newegg.com/Product/Product.aspx?

We just acquired a property in suburban Portland OR where almost half the tenants had bought and installed window air conditioners (with various amounts of skill).

I am willing to offer water and most electricity at no extra charge, but I'd like to put something in the lease that requires payment towards oil and air conditioner usage over a certain point. 

No additional pieces outside and it isn't those air conditioners that go through a wall like in some motels.Below is a link to the entire piece: https://www.gemaire.com/first-co-18spxa8-hp-1-1-2-...These are used as central air HVAC units in condos, apartments, etc.

No the circuit breaker cannot handle two air conditioners and a blow dryer... 

I think electric is something you should always have paid by the tenant since it can be extremely high, especially if air conditioners are used. 

I am considering replacing a split system air conditioner/furnace in a 1000 sq. ft. 3/1 rental home with a new 2 ton AC unit and a 70k BTU gas furnace.
