| 1 | hi have a new heatpump , toshiba, had heatpumps before but this plastic seems
louder when heating up and once cooling down from turning off.. occassional crackle when running.. guess thats normal ?? it works fine daz1968 - 2021-04-23 08:40:00 |
| 2 | Never really noticed new ones being particularly loud, but they all creak a bit as you know, with heat expansion then cooling off contraction. Hope it settles after a few months use, but if not, i would ask for supplier to check it out, if is still seems abnormal.(installed hundreds, and serviced thousands over the years -since 1980, never had a call to check one for that issue, but there can always be a first one). A recent common issue(1-2 years ago) was out of balance fan wheels, causing vibration rattles and obvious shaking of indoor unit. Edited by gpg58 at 9:02 am, Fri 23 Apr gpg58 - 2021-04-23 08:54:00 |
| 3 | If still concerned after a week or 2's use, perhaps take a video trying to record noises, and upload to youtube so it can be listened to by warranty(and us).
Thinking further, It is possible its an install issue, as ones with crushed pipework can make loud noises, (but usually also have poor performance).
Seen plenty crush the pipes where they exit thru wall, as well as anywhere else they bend them, or feed them thru something. Edited by gpg58 at 9:52 am, Fri 23 Apr gpg58 - 2021-04-23 09:49:00 |
| 4 | mine where noisy for a fair while. but they eventually settle in.
i wonder if it also comes down to how tight the screws have been done up. i wonder if it would pay to run it at max temp for a while and also at minimum temp. that should create maximum movement and help wear those joints in. tweake - 2021-04-23 15:13:00 |
| 5 | Do they need some sort of rubber pad/washer between where they are fixed for noise reduction???: lakeview3 - 2021-04-23 16:32:00 |
| 6 | he has been back this arvo , we have worked out part of all the noise is when in swing mode, so dont use that anymore, if it keeps making a decent amount of noise while running for a while will mention again , its definately a noisy unit while warming up and cooling down though , hes invoiced me now to no mention of the toshiba warranty though but he did say 5 years , cant see anything in booklet either , if anything he has done his job right its more the unit daz1968 - 2021-04-23 17:04:00 |

| 9 | Toshiba warranty goes off the serial numbers of the units, so original invoice only needed if it sat around in someone's workshop for a long time, (as serial numbers relate to who it was sold to, and when only, not actual install date, yes 5 years) - this also means you do not have to use same install folk, for repairs if needed.
Had a couple of noise complaints, related to wind generated in some parts of the swing cycle(only on the big units, ras-18 and up), most just find where best airflow position is, and leave them set there. Personally i hate swing mode(any brand), due to the constant drafts as it swings past, annoying the heck out of me. But you can usually set the ranges they swing within, to limit it if you must use them. Edited by gpg58 at 6:17 pm, Fri 23 Apr gpg58 - 2021-04-23 18:06:00 |

Yes you can contact AHI Carrier - Toshiba warranty directly, if problem continues, and you have lost faith in the folk you are dealing with.
They will likely arrange for another company to visit, and give a second opinion, if it is thought necessary (i did this work for them locally - now retired).
BUT things will progress much quicker if you have a video or even just a sound recording to prove an issue exists.

| 12 | i would be inclined to give it some time.
its actually mentioned in the heat pumps manual on mine.
they do settle down after a while. tweake - 2021-04-24 10:25:00 |
| 13 | maybe I will wait a couple of weeks then , will pay installers invoice , I feel its not an installation issue, and he did come back , I will email him and ask about contact with tosiba to check it out and see if he has to or me.. by the sound from previous post as long as I have inv and serial code etc etc I can take it from here ? daz1968 - 2021-04-24 12:41:00 |

| 15 | Moved into a house - heat pump creaked quite badly when turning on and off.. Didn't think too much of it, as was new to owning a heat pump. One day, a knocking noise started, so called in a technician. Wow, the creaking WAS NOT normal! The knocking was fixed straight away with a spanner, but it took a couple of tries and parts to get the creaking sorted. Lucky for me, the heat pump had a 5 year warranty and it was only a few weeks from running out! Call your installer! hazelnut2 - 2021-04-25 07:56:00 |

Personally if i was called to it, i would be inspecting the pipework for damage first, have seen a fair few with crushed pipes causing noises and bangs etc.

Even had one once, that installer had left his internal poly bender in the 1/2" tube, which was rattling about and causing dismal performance. Generally Toshiba are among the quietest as a rule, and frankly at the same airflow in m/s, they are all fairly similar, within a db or so. Curious if this a back to back install, or indoor on an internal wall with pipework going into ceiling, or under floor? Edited by gpg58 at 7:35 pm, Sun 25 Apr gpg58 - 2021-04-25 19:20:00 |
| 20 | A few more pics for those interested, of some of the supposed warranty faults i went to.

https://trademe.tmcdn.co.nz/photoserver/full/1530527309.jpg
Ps - chassis had been twisted in the process, causing fan to be out of alignment, and vibrating like heck.
Also likely would void all warranty as not an approved way to install - (according to head of warranty at the time).
As for having joints inaccessible inside wall, or up in ceiling.... enough said. Edited by gpg58 at 8:21 pm, Sun 25 Apr gpg58 - 2021-04-25 20:10:00 |

530525447.jpg nice hole for hot air to escape out of and wet air to get into the wall.
do any of them seal up the hole around the pipes? Any competent installer seals all entry points, at either end(foam gun is simple).
That's another common issue for indoor units, drafts from unsealed hole, effecting room temperature sensor on some models. Along with mice getting in and chewing things, and sitting and shitting in back of unit, lovely to find(not) when servicing them(along with occasional dead ones).

Goodo, just a standard back to back install, so less chance of piping damage, except at pipe exit or unit connection.
Would love to hear sound myself.
Wondering if some reversing valves are still playing up. - curious what size/model unit. Faulty ones were mostly on older r410 gas units(usually at 3+ years old), but did have a brand new PKVG13 (r32 gas) one as well. Edited by gpg58 at 7:19 pm, Mon 26 Apr gpg58 - 2021-04-26 19:05:00 |

Just having a coffee with a rep, he is not aware of any current domestic units having a common fault, so hopefully replacing it should be the end of your issue. Edited by gpg58 at 2:32 pm, Tue 27 Apr gpg58 - 2021-04-27 14:27:00 |
