Hi,
I have a TRANE XE1000 split unit HVAC system at home. It has air handler/evaporator in the attic and compressor/heat pump on concrete slab outside. This system is 20 years old now this year.
I am already looking into cost-effective solutions for when the system fails. Maybe it still has years of life left, or maybe not. My single level house is in Arizona desert and is 1251 square feet. It has no basement. There is no room to install equipment inside the house. If possible, I'd like to not work out of the attic anymore at all. Incredibly hot in summer, and cramped quarters up there. Ridiculous location for HVAC equipment. Are these options that might save me money:
1. Have myself install the units in attic and outside slab and pay technician to hook up connections.
2. Install mini-split units myself. How many would be needed?
3. Eliminate the attic altogether and place split units side by side together on slab, or backyard and route ducting into attic. Existing slab is on one side of house. So would this cause uneven distribution of heating and cooling in house?
4. Would three powerful window units cool my 1251 square ft. house sufficiently? Would these units be too noisy?
5. Can I replace one unit at a time..............or does the old equipment jeopardize the brand new unit?
My neighborhood does not have a HOA.
Planning ahead for home HVAC replacement when the time comes
