Tip & How-To about Heating & Cooling

Airconitioners tips


  • Check all hose connections for leaks. Repair leaks
  • Make sure the condensate tube is draining freely.
  • Change or clean the furnace filter once a month. This is especially important during the summer when dust and allergens circulate.
  • Clean the outside compressor by spraying it with a hose.
  • Keep plantings at least one foot away for adequate airflow around the entire unit.
  • Vacuum registers and air vents regularly.
  • Have your ductwork professionally cleaned every few years.
  • Keep furniture and drapes away from registers.
  • During the winter, keep the compressor covered and remove window air conditioners.

Ultra SX90 High Eff furnace leaking water from motor. Air filters clear. Water line to the white PVC and to floor drain was not plugged. Looked at the coils and the pan is dry. Air filters clean.


Check drain from bottom of condensing furnace, check that drain hoses are routed correctly. Hoses have to be rerouted if converted to horizontal flow.

I have a Goodman system and I have water leaking from the the small box next to my furnace. I have what looks like 3 lines running from unit to this box. One is a small copper one, another is a line wrapped in insulation and the other is a clear plastic hose. I look at the clear plastic hose that runs to it from the ac unit and it looks clogged with dirt all through it. Not sure if thats the problem. Also a side note, my air gets cool but not cold. any suggestions


the clear plastic hose is the condensate drain .. indeed they clog frequently .. lthat will allow water to overflow the pan that is desined to capture condensed water from the evaporator.. the plastic hose and the pipe it is attached to need to be cleaned out periodically ... allowing water to overflow can damage other things so its important to get the drain cleared .. however that drain has little to do with cooling efficiency .. your lack of cooling performance could be another problem ... sometimes the evaporator coil gets clogged (large finned unit behind where the overflow hose is attached inside furnace) .. that has to be cleaned once in a while but is tricky to do ... how often depends on how good the furnace air filter is and how often its changed ... as the evaporator becomes clogged with dust the cooling efficiency goes down .. same with the outdoor unit ... you have to wash out leaves and such periodically from the condenser coils .... if every thing is clean but the cooling efficiency is still low then have the unit checked for refrigerrant pressure .. it could be low .. of course make sure the furnace filter is not clogged ... also for cooling make sure all of the registers are open ... closing some can reduce overall efficiency ... make sure the outdoor unit fan is working properly ..

Water leaking out the bottom of my Furnace


One of the drain tubes (overflow) is plugged. Unhook each one and clear them of any debris.

GMPN goodman furnace: Water leaks from the base.


Check the drain tubes inside the furnace. There may be a loose connection or a split tube.
The unit could also leak from the gasket between the secondary heat exchanger and the vent fan housing. The secondary heat exchanger ould also be leaking or cracked.
Hope this helps.
