What kind of bus do you have?

Some of us wierdos are installing home-style mini-splits and keeping our roof lines cleaner and lower. Plus they cost half of what a roof top unit costs. In my case, they only draw 9 amps max, compared to 15-20 for rooftop units. Just another option for you to consider.

Where are you buying mini-splits for half the cost of a roof top?  Are the prices in Mexico that lop sided because mini-splits here in the USA seem to cost around the same as a roof top.

Here in Mexico we paid 6,300 pesos for each mini-split. These also have the heating elements installed. Each rooftop unit would cost us 14,000 pesos down here. Exchange rate is about 13.5 pesos per dollar.

I used to have a travel trailer with ducted A/C.  The ducts were maybe three inches tall.  I suggest finding the installation manual for a rooftop A/C and it should list the required dimensions for the duct work.  Typically the duct work is sized in square inches of area.  There is a fair bit of leeway in how wide and tall the duct work can be as long as the square inches are right.

Mini-splits require no duct work.

I live in Houston and wondered where/who could I order a mini split from? Brand? more info?

Steve, how many BTU's are they each, for 9 amps (at 120 volts?) and is the 9 amps for both units (evaporator and condenser?)

     Here is a section from a "single-zone" mini-split product specification:

Type    Rotary/Scroll
RLA (Amp)    4.5
LRA (Amp)    26.0

     What do the RLA (Amp) and LRA (Amp) numbers mean?

Are you in Mexico? I am 100 miles North West of Mexico City. I bought them here in town. I would imagine buying them and shipping to the U. S. would cost an arm and a leg.

Here is the tag on the box. I exaggerated when I said "9 amps". They take 8.5 amps max. They are 12,000 btu each.
