Evapoative air conditioning

My air con unit is not filling with water when I switch on. Pump and motor working fine. I suspect valve used for dumping water is stuck open as i tried to manually fill it and water just drained. Is it the dump valve stuck open?

Re: Evapoative air conditioning

Sounds like the flaot switch is stuck in the up position. this will be like the drain pan is always full of water. You may need to take the unit apart and check the flaot in order to reapir this problem.

Air conditional water drip

That happened to us. It was a broken pump, pump was up in attic. attached to our inside air-con unit. We had it fitted on an inside wall of the house, and so a pump must be installed to take away the condensed water to the outside of the house. Hindsight being 20/20 I would never buy one that needed a pump to get the condensed water out of the house. We would have put it an outside wall where the water goes straight outside, no pump needed. Our First pump lasted just over 2 years so warranty was expired. Cost us over NZ$500 to have new pump installed. Never again. Only attach your unit to an outside wall, even it looks prettier on the wall where it would need a pump. Bottom line:- Don't touch a pump. Pump was cheap but labor cost for serviceman astronomical! Bet of luck.

Hi, my air conditioner works fine but if I leave it on to long it will start blowing out warm air. Then when I turn it off, it sounds like its still on. And I have to wait a whole day before it blows cool...

Sounds like the unit is icing up.

Window air conditioners are not usually of sufficient capacity to keep a room much below 74°F. If not allowed to cycle off occasionally during the day, the evaporator (cold radiator) will ice-over and prevent air from passing through it.

The way most are constructed, the water is designed to drain to the bottom near the compressor. The heat of the compressor and air provided by the condenser fan motor are intended to evaporator the condensate.

Try using a higher setting on the unit and see if that helps. It needs to be able to shut-down once in a while. If you have the option, set the fan switch to 'on' instead of 'auto'. This keeps the inside fan motor blowing all the time, with the compressor cycling as needed. The moving air will make the conditioned space more comfortable with a higher temperature setting.

Water dripping from air con use

If the unit is mounted on an outside wall check the condensate drain that comes out with the line-set to the outdoor unit. If the pipping goes up into the attic than you have a small condensate pump that may have failed. The float in the pump may have stuck in the down position not allowing the pump to come on.

I have just installed a Bionair Evaporative cooler. But when its turned on it will not fill with water. Unit has water connected but unit will not pump it in? Other than that its working fine, fan is...

check the float assembly. wiggle it up and down. is water dripping there? if so, you know water is getting that far, you need to unplug the plugged area.. Also check the water line and ensure no shut-off valves are turned off.

Do not know how to work/maintain swamp cooler

Make sure you have water to the unit, the water pump is on and the fan is working. No water=no cooling.

Amana HTM (heat transfer module) system

I would check the house thermostat(and its wiring to the indoor unit), and if it's OK then check the heat transfer fluid diverter valve inside the indoor unit (should be sending the hot fluid through the big radiator (air exchanger)) until the surface temperature of the radiator is approximately 130 degrees F, then the fan control operates and the fan starts to blow hot air through your ductwork. My HTM is 26 years old and I've had many opportunities to "hone" its operation...
