Brand New 2 weeks old 4 ton Trane compressor leaks a lot of water onto pad


If the unit is running in cold weather than there is ice building up on the coils located outside. This is normal in that the unit is running in heat pump mode heating inside and cooling outside, After the unit detects the ice build up it briefly reverses the cycle heating the outside coils melting(defrosting) the ice which you observe as water on the pad.

The video gives you an example of the defrost cycle!

I have a RUUD Heat Pump Model UPPB-024JAZ the outdoor pump stopped working last week. The reset button fixed the issue but whhy does it keep going off.


To start with, the tech charged you for an hours worth of service and only pushed the button. GET YOUR HOURS WORTH!
•The outdoor coil needs to be cleaned. Turn off power at the breaker and t-stat, clean the coil with water hose
•The outdoor fan motor may be slowing down or stopping due to motor bearings dry or weak run capacitor. Any noise/squealing from motor?
•Too much freon in the system.
•A restriction in the freon system.
•A improperly installed/mismatched system
•A (kynk) in the liquid line(3/8 copper)
•A stopped up or clogged filter dryer
•A dirty indoor coil that has an expansion valve(txv) will run too cold and the valve can close near "seated"
All of these, and more, can cause a HIGH PRESSURE SWITCH to open. When yours open, you have the red button to push which resets it(the switch). I have also found that the plenum(duct box that connects to your indoor unit at the discharge air) is supposed to be tapered to the air opening size of the blower outlet but that's hard to explain. If the plenum size is the same size of your indoor unit, width and depth in the upright position, the your plenum is not "tappered"(goes from one larger size to smaller size where connected to the I.d. unit). In that scenario, the high pressure switch opens during heat operation, not cool. I know, confusing. Try cleaning your o.d. coil first. And try to get an hour of work(or close) for an hour paid. And WORK SAFE!

BUZZING NOISE FROM MY HEAT PUMP


Take a look at this YouTube page that explains with good videos what are some of the common problems with heat pump noise. The one that seems dominant is the defrost cycle a heat pump goes thru when it melts ice off the evaporative coils. In defrost cycle, The compressor runs but the cooling fan does not, so you will hear a loud buzzing sound and the unit sounds like it is stalled...because only the compressor is running to generate heat to melt coil ice.

Goodman package- no heat below 30 degrees outside


I believe the unit you are describing is a heat pump. Heat pump are great when the temperature isn't below 30 With low ambient temps. outside it is much more efficient and comfortable to run aux. electric heat from the heat pump.

2 weeks ago one of my units stopped working properly. It got warm during the night even though I heard the unit running. I shut it off and called for repair service. They changed the thermostat and it...


sounds like the coils inside the air handler/furnace are freezing up. likely cause is the freon charge is incorrect (probably undercharged). it may have been correct when the tech did the work but some may have leaked out. it is slightly possible too that the system is overcharged. you should have the system pressure verified, and then have it checked for leaks.

My haier a/c window unit is spitting water through the vent


check the filter located behind the front panel it usually snaps out also make sure the drain holes on the out side bottom of unit are not stopped up and that the unit is leaned back slightly for drainage freezing is a sign of low air flow or low on freon the coil actually gets colder when freon starts to leak out hope this helps with your problem

Fan motor comes on, however, when a/c is turned on, breaker pops


If the unit is working fine in heat mode and in fan only mode, you have a short in the wiring going to the ouside unit. If it were a fan relay, then everytime the fan came on the breaker would trip. But either way, there is a low voltage short taking place in the unit. If the compressor was bad, the indoor unit would run fine and would only blow the breakers to the ouside unit. I had a unit last summer that did the same exact thing. After I replaced the control wiring to the outside unit, everything worked like a charm. Good luck!

New 14 seer split ruud heat pump makes very loud knocking noise


Well you may want to have a tech come out and check the freon level, but mostly when going into defrost, some units make alot of noise, the freon is reversed in the unit by way of the reversing valve, it makes a whooshing sound like freon is draining off, as far as the knocking noise, could be as I said in the beginning, might be low on freon, but it could be that, this particular unit does this, I have had units make some really strange noises in the past but functioned perfectly, hope this helped, please let us know, thanks again,
