Inverter AC Units and Electricity Bill

[jason_79]

For those who own one of these inverter units, please share your experiences and electricity bills

[shaneelal]

I'm considering this also, getting 12000BTU normal Coldwave for $3200 and 12000BTU Panasonic inverter for $7000. It's hard to justify spending that extra unless electricity prices are set to rise soon.

you will only save long term as electricity rates locally are much cheaper than in the US and the cost of the unit is much higher than a regular unit so it may be possible that by the time you realise savings on the bill it may be time to replace the unit based on its usage

[ado15mk3]

my panasonic inverter that i bought in 2010 for 7000 still going strong. so quiet you wouldnt even notice. my elec bill was reduced by 100-150 per bill [saved approx 1200-1800 thus far].
as sr said its a long term investment. but with this unit i am sure i would make it up since that thing running like a toyota. i wouldnt put my head on a block but i sure it making more than 5yrs easy. only thing is that i delinquent with servicing. i only service 1/yr. was recommended to do 1/3mnths.

Advantages are not just with the reduced power consumption, but as the other posters said it's much more quiet. You don't get that compressor 'kick' and light dimming effects of traditional non inverter units.

Plus the operating nature of these units allows for a much longer life span with less maintenance.

Just like a Toyota

Where you bought your a/c ? Isn't your warranty void by not adhering to maintenance schedule?

You saved about $1500 in a 2 year period.. that's not so bad.

I in the market right now, but I need an 18,000btu and I fraid to ask the cost of an inverter that size.

Westinghouse dealer doesn't have any in stock and not so familiar with them. The York dealer didn't know much about them either. Same for Innovair and Lennox..

I didn't speak to Daiken and Panasonic yet.

Service intervals are normally recommended by the environment the equipment operates in

any good contractor should recommend the service period based on that as well as other factors.

and yet still you eh speak to me or even speedy

[TeamH2O]

Anyone know about the Royal Sovereign Portable A/C Units, 11,000 BTU.....I have one, and every billing cycle(2months) the bill is like 697$....In an apartment so not gonna install window or split unit. The bill is 106$ higher T&TEC said even when the apartment was vacant so we waiting on an electrician.

But im just asking if these portable units pull more current than normal window/split units? Its 110 power plug in to normal wall sockets

cant remember the name of the co. but they just after gulf city on the right (in gulf view) if you heading point side.
who does worry bout warranty when you have a toyota?

i have a 12000btu. when i checked daiken, i would have had to sell my car to get a 12000btu unit but reviewers does quote 20 yr life span an ting. guess toyota aint all that after all

[pugboy]

switch to a tankless water heater also,
we save about $100-$150 per bill compared to before with a 40gal water heater

[ado15mk3]

have one of those too. how do you use yours? mine barely gets a workout. i set it to 35 and therefore dont need to mix. do you mix? never had a heater before so cant comment on energy costs. was cold water in my ars yes.

[xtech]

Think that's expensive!

A fully DC aircon 12,000BTU unit is $1,500USD

[DVSTT]

What temp you guys set the units at? How big an impact on cost does the temperature setting have?

[SR]

cooler the temp the more the unit will have to cycle depending on the room and if there are leaks as well as number of windows and if the room gets direct sunlight

[TESTED performance]

I was hoping to find more info on inverter AC units on trinituner than what currently exists. Guess it's time to wake up ah ched.
my 2 cents is that I thought the MAIN reason for installing an inverter unit is because of how they function. I have a number of temperature measuring devices and I can assure you that regardless of what temperature you set a regular split unit to it will NEVER EVER cool the room to the set temperature because it's simply incapable of doing that by design. Inverter units can ACTUALLY hit a selected room temperature target because from what i've read they vary the amount of cooling via fan and compressor speed without ever allowing the room to heat back up as normal split units do during the compressor "off cycle".
Can anyone confirm this who actually owns one? Better yet someone who has an innovair inverter since that's the type i'm considering installing!

[bluefete]

Temps 21/22. But bill averages $500.00 - $550.00 (about $300.00 prior to the a/c install). 2units @10,000 and 13,000 btu's inverters.

Not on continuously.

I find the bill is too high.

[TESTED performance]

could be just preference but I think a 21/22 deg celsius setting is unnecessary coldness if you're using an inverter. Again theoretically they should be able to hit an EXACT room temperature instead of bouncing around the mark like regular ones. I am 100% sure that if this is the case a simple increase in temperature setting by 1 degree would significantly impact your light bill. I find that an average comfortable room temperature is 24 degrees celsius for those who like it colder and around 25 degrees for those who want a cool room. AGAIN this all depends on if the inverters work the way I think they do.

my units are usually at around 24. I don't understand people who feel the room must be freezing at 16 or 19 otherwise the a/c eh wukkin. It's called an air CONDITIONER, not a chiller, and you are not meat or produce.

I'm so rusty I was looking for a like button to click after reading this lol. Either way I don't think that degrees celsius is the best scale for measuring temperature. If I can play devils advocate here I think it would be more objective to look at every 1 degree celsius as comprising of 10 degrees of noticeable change in temperature. So in other words even if your room temperature stays within the 24 degree celsius range but went from 24.1 to 24.6 degrees you would feel as if there was a VERY significant change in room temperature. It is for this reason that I believe home AC units should be able to control room temperature to within 0.5 of a degree celsius instead of working only in 1 degree increments. (yes I already know that I'm a nerd guys no need to point that out after reading this.)

Just a heads up... Depending on the size of the room that it's required to cool and the heat load (how hot the room gets during the day) as well as how well the room is sealed off... anyway it's possible that a 10,000 BTU inverter may struggle to cool down the area effectively enough to also be able to eventually operate at a lower compressor speed when the target temperature is reached.

The situation I assume that is existing is one where the inverter keeps running at or close to 100% compressor power consumption to cool the space which will send your light bill through the roof. Remember the compressor(the outside part) is what utilizes 90% of the power your ac is consuming not the evaporator(inside part).

The compressor in the inverter unit is designed to run continuously instead of switching off like typical standard ac units do. For this reason it may be a good idea to oversize your ac inverter unit by a couple thousand BTU of cooling capacity just to ensure that it will be able to cool the room down to the set target temperature much faster then efficiently function with the least power consumption upon reaching the set target room temperature.
That said, I don't think $500-550 is an excessively high light bill depending on the other appliances that are being run during the billing cycle.

[pugboy]

it probably set so at 16 because it undersized so the poor unit going all out just to get to
a regular cool temp of 22-24

[STORM1234]

it have lg, toshiba and pioneer units on ebay, after shipping to might cost you about 6000 for a 12k btu unit.

[redmanjp]

some A/C energy saving tips:

http://michaelbluejay.com/electricity/cooling.html

personally we use a fan in conjunction with our AC so we feel cool even with the AC on 25C- what i have to do now is get one of those door draft thingy or what u call it to block the wide gap under the door to prevent convection

we only use the AC occasionally (6-8 hrs per week) so not much increase in the bill

first bill increased from about $250 to $300 but AC was installed around the middle of the billing period so next bill would be higher

[TESTED performance]

did you have a regular ac installed or an inverter type? Just want some idea about the differences of using the inverter types. Please share any personal experience/opinions you have.

both units will hit selected temperature, in case of the regular unit its either fully on or fully off,if on it would pull down to your required setting because its at maximum all the time . In contrast , the inverter type ac system varies the speed of its motor according to its load so it starts off at maximum like the regular ac and then slows down as the temperature drops saving you energy so basically the regular unit will get there first along with the noisy start/stopping cycles that follows, to say that the regular unit is incapable by design to come down to a preset temperature is error

it's a regular split AC

Yes I've used wikipedia before and I get it... makes you feel as if you actually know stuff BUT... uh you clearly don't have an inverter ac unit installed nor do you understand how regular split units really work. I am ONLY interested in feedback from people who OWN INVERTERS. No one else needs to try to explain how they think it works to me. I already know how it works. I just want the opinion of someone who installed it and has hands on personal experience with them. thank youuuuuuuuuu!
