Aloha,

Has anyone had one of these systems installed and if so, what was an aproximate cost and do you have any one you would be happy to refer?

I just recieved a rough quote for system and installation of $4,000. per bedroom and $7,000. per open spaces. At that estimate, a three bedroom home with open living, kitchen and dining would cost $19,000. for a split system on kauai. Could this in anyway be close to what the going rate is on island? Mainland would be $5,000 total for a 3 bedroom home. It very well may be a going rate estimate, yet... lol


Has anyone done their own install, forgoing the permit for appraisal value on the house to save what would be $17,000 in this example. Just the system with 3 room units runs $2,000 retail.

Mahalo

I recently had a Split Ductless AC System in my 3 bedroom guest house (2 levels) - The house is roughly 1,800 sq ft.

These are Oahu prices: (C.S Mechanical - happy to refer - I suspect they'd fly over from Oahu - install takes 1/2 day)

Downstairs (living room, kitchen, dining room): Fijitsu 30,000 BTU Model 30RLXB Parts and Labor: $4,100
Upstairs - each bedroom Fijitsu 12,000 BTU Model 12RL2 Parts and Labor $2,500 each bedroom

Total: $11,600 The units are highly energy efficient and qualified for a rebate from the state for $700.00 to bring the total cost down to $10,900

All units run 24 hours a day, 7 days a week and add roughly $120/month to the electric bill. Highly recommend those models - super quiet, use little electricity, chills the room fast

Wow,

That is significantly less and leaves room to fly them over if need be. If this works out to be my best bet, I will hit you up for their name.

Mahalo!!!!

Hi viper, these only add $120/mo to your electric bill?

That is awesome - we are looking at these (3/2, one level, 1600 sq ft) but were going to wait until we installed solar to keep the electric down. We might want to go ahead and do this sooner rather than later if they are that efficient.

I can only speak for my units, but the impact of the electric bill wasn't that much. It all depends on how energy-efficient your units are, window units are notoriously bad at electricity and can be five times worse than your electric bill than the split A/C units.

If you are good at math - you can calculate how much your electric bill will be if you know what the SEER number of the unit is

Just beware of poop on the split AC main unit PCB.

Unless your entire guest house is literally built and insulated like a chest freezer (which I suspect it is not), there is no way you are cooling 1,800 SF 24-7 for $120/mo. New splits are very efficient compared to window units but that is not a realistic number.

What are the ac unit's thermostats set at?

It is - what it is. $120 tends to be peak/summer - closer to $70 in winter.

The upstairs/bedroom units run on 110 volts - downstairs is 220 volts. The units generally run at 76 degrees - and while that may seem high, when it is set to 74 most people who come into the house find that too cold....

The 30,000 BTU unit alone, running 10 hours a day, 30 days a month, would use a minimum of 600 KW, which, at 30 cents per KWH, would cost 180.00 dollars a month. Besides, if this IS a rental unit, and you're not living with your tenants, how could you know the AC was running 24/7? Soooo, this one doesn't quite pass the smell test. That's OK though, there's a lot of that going around, (just watch the news.)

Ok. I do have some breaking news.

Running 24/7 means the units aren't turned off. They have a thermostat (you know, so it isn't running full blast all the time). In fact - they are so quiet it's hard to tell when they are pumping cold air or on standby.

Upstairs.
