Question about Heating & Cooling
The outdoor coils getting some frost on them is normal. However the system should periodically (every 30-90 mins of run time) go into "defrost" mode. Essentially it reverts back to cooling and shuts off the outdoor fan. This heats the coil outside to melt the frost. You may see some steam at this time also. Again normal. If this is not happening or not happening often enough the coil will ice up. Inside the outdoor unit is the defrost board. There is usually a pin setting for either 30-45-60 or 90 minutes. Make sure you kill the power to the unit before sticking your hands in there. Check to see what setting your is on and lower it one peg. If it's been colder and/or more humid you may need to cycle sooner. Good luck I hope this works for you. Please don't forget to give me a Fixya rating.
