Ive learned a lot about Mini Splits. But I still would appreciate some expert advice please. Ive narrowed my choice down. But I don't know which is better: single zone or dual zone.
A few specs for my house: I'm in Arizona, elevation 6,500 ft. Low temp -3 F High Temp +/- 100 F. The house was built in 1934 and is 683 sq ft. (It's tiny). There is no duct work or system of any kind for cooling. Heat is propane space heater from the 70's. I'm looking to put 2 wall mounted units in Rooms the size of: bathroom/ office 11 x 9 & LivRm/ kitchen 24 x 14.
Does it make more sense to go with a multi-zone unit (single outside compressor) or two separate units (one for each room)? Which one is cheaper to run long-term?
One last question: Where could I find an estimated cost increase to my electric bill post install? Just to give me an idea what to expect when the bill arrives..Thanx for the help
