Question about Heating & Cooling
I have a 5 year old house 2000 sq ft, 3 AC ton unit. The past 4 summers AC has done a good job of cooling the house. This summer not so much. Had a recent freon charge and AC guy cleaned outside unit coils of debris. From hours of 12 PM - 8 PM AC runs the whole time and can not cool to below 80-82. At night AC works well again. Cold air is coming from vents but maybe seems like warm air is not exiting house right. Any ideas?
Your AC cooling efficiency is low when he ambient temperature is high and naturally it cools well when the outside temperature drops.
Please remove the filter on the grill and try to clean it under the tap water and after removing all the dust fix it back to the unit. This would increase the cooling efficiency of the unit.
Your AC is also five years old. Please avoid frequent opening of doors or windows.
Ensure that the exhaust fan and the blower of your unit are functioning normal.
The technician might not have done a proper job in fixing the area where the refrigerant would have leaked out. Please check the refrigerant pressure to ensure that no further refrigerant leak has taken place. Or even servicing your unit he would have punchered the tubes resulting in very slow leak of refrigerant resulting in no cooling or less cooling. It takes around a month to feel the pinch of it and the refrigerant. One fine morning after sometime the unit will run and it would start throwing hot air instead of cool breeze!
