Posted By Topic: air con condensate pump

Jan 13 2019 20:03

Friend of mine had a 10 year old Daiken heat pump, faulty, not working properly. serviceman came out, said at 10 years old a new unit was the best option. New unit installed but condensate pump was removed with old unit, friend quoted extra $500 to have new pump fitted. This was after new pump installed and old unit gone. Friend declined this quote and can only use pump as a heat unit. This all happened last winter, I only found out today. I am sure the condensate pump from the original unit could have been refitted to new unit.Friend is 80 years old and I feel he has been conned. If pump was no good a new one should have been included in quote. Thoughts from air con experts??

If it was needed for correct operation then it should have been included with the quote, or specifically excluded as an optional extra.

The pumps are only around $200. So $500 is a little on the high side. But there are some more expensive ones as well.

It wouldn't be ideal fitting a 10 year old pump to a new unit, and expect it to last another 10 years or so. I wouldn't do it.

As a temporary measure run the drain down to the floor and put a bottle there. Swap and empty as required. Not ideal but at least can use on cool.

He needs to this sorted as soon as he can!

Even on heating, you can get condensate in the indoor drain tray. On heating, on cooler nights, and colder climates, the outdoor unit will need to defrost the coil from time to time.

When this happens, the indoor fan will (or Should) shut down to prevent cold draughts, and the reversing valve in the outdoor unit will change over, and divert hot gas from the compressor into the outdoor coil to melt off any ice build up.

While this happens, the indoor coil can, and frequently does, frost over, which melts off when the valve changes over again at the completion of the outdoor defrost.

Depending on how long the defrost has taken, the frosting on the indoor coil can produce a reasonable amount of water, which has to go somewhere!

I would suggest that the installer is nothing more than a cowboy with little or no knowledge of refrigeration and how a heatpump works, which is usually the case when an electrician buys a set of guages and a vacuum pump, and should be taken to task about installing an appliance that isnt for for purpose.

There are provisions in the Consumer Guarantees Act to allow action to be taken on that.
