Last night our mitsi heat pump starting making louder than normal noises.   Going up close it was almost like its 'pulsing' or 'surging', it sounds like it is blowing harder for say 2 secs then softer for 2 secs, then harder for 2 secs and so on.

 

We've never heard this before.  Did the old turn off and on again, no change.

 

Anyone know what this could be?  I've turned it off for now in case it is serious, and will get someone in that's the thing to do.  But perhaps there's a known solution out there.

 

Thanks

Can you call the installer? If you didn't have it installed sometimes it's written on the outdoor unit. You could also try calling the manufacturer.

The filters were cleaned about 4 months ago, we get them done annually by the installer.  But I will check.

 

Its the internal unit, and was on cooling.

 

It is definitely more noisy than we have heard it before.

There is no need to get outside help and pay them a whole pile of $$$ to do a simple filter clean - unless you are so old you can not get up on a chair to open the heat pump and get the filters out.  Filter cleaning is designed to be done by the user and is very easy.  Your heat pump manual tells you how to do it.  If you have lost the manual, it can be downloaded from the Internet, usually directly from the manufacturer's site.  Dodgy heat pump installers often tell you that they need an "annual service", but there is no truth in that and your heat pump manual would tell you if that was needed.  And what the "service" would entail.  "Annual services" are just a scam.

noise is highly subjective and difficult to diagnose over the net.

 

could simply be gas in the pipes noise, or the fan speed. some brands/models will bounce the fan speed up and down depending on conditions and settings. eg one of mine does it when on quiet mode. it runs the fan at slow speed then increases fan speed when it starts cooling. you can hear it short cycle at times.

 

sometimes you can get fan speed change due to change in air temp due to drafts or heat soak. fan stops/slows, temp goes up so fan starts which sucks in cool air and drops the temps so fan stops/slows.
