I'd make sure the A/C you choose has a fan only option. I've had tenants look at this to save on power.
I agree with the smaller one in the living area and one in the master. I actually got one for the master with 2 head units. One in the master and one in the bedroom next to it but only one outdoor unit. Cost an extra $450. It was also great for resale.
If you've had a quote more than 2yrs ago, you'd be surprised with the current pricing.
Also if you're in Qld, the peak period for rentals is Jan. If you do an open on the hot day or week, guess who will win.
Cheers.
Extra $450 for another head unit in the bedroom.?
Must of been some no name brand and even then the installation on the second head unit would have been at least $450 extra. So more than likely going on even capacity to multi head to single head systems you would have been at least a grand more if using quality gear and indoor units were within 3 mtrs of the outdoor unit.
It's actually cheaper in the domestic world to install separate units if the installation works are apart and you use only first rate gear like Fujitsu/ Mitsubishi elec or Panasonics with fan only options as well , yes units are 100 to 200 dearer than 2 years ago due to the carbon pricing of the refrigerant gas they contain but the wholesalers are very competitive over last 12 months so prices have remained stable and installation costs have been same for last 3 odd years so prices have remained same give or take a buck over last 3 odd years.
If you were going multi head system to cover whole house you might as well put full ducted system in for slightly dearer cost but better resale value.
Multi has it place in commercial and in the llimited times it suits domestic your best to go with 1 or 2 splits on a rental with maybe some fans, and in a higher end property full ducted if it can be installed and I stress, use quality efficient gear for performance, future parts availability , and future resale positives.
Multi is good for some townhouses and units with body corp requirements.
There are numerous systems and options out there to suit all properties/ budjets, just make sure your installer holds a full RAC license and not just a " restricted splits install only license " which alot of guys are getting so you can get him back for future repairs/ service work etc legally and also knowing the installer is full trade qualified and not some weekend warrior out to make a quick buck. I have seen some seriously stuffed up jobs in my travels out there and fixed many up or ripped them out and started again.
Rewind 6 years ago and you were paying close to 50 to 80 percent more for AC with less efficient machines,
It's a no brainer now in good rental properties as they are tax deductable, adds value to house, and keeps good tenants happy as well as keeping me in a job
