It sounds like thermostat which tell unit to turnoff
and set the temp. you can test them with hair dyer buy putting it on heat see what dose then cool. The display should show the temp. if so then it should shut off or turn on is. If not could be a bad thermostat. Or is the thermostat in a hot spot in the house is should be near the return. Hope this helps. Yes I do for living Paul

you will need a thermometer, you can use a meat therm.take a temp reading of the air going into the return and then coming out of the supply at the unit, it should be at least 15 to 20 degrees cooler in the supply, if not it may be low on refrigerant also check filter and return duct make sure your not pulling air from attic

It sounds like you are low on charge. I think you have a thermostatic expansion valve and you need to check the subcooling, you should have 12 to 15 degrees at 95. At 95 degrees your head should be about 280# for a 12 or 13 SEER unit or higher depending on the effeciency. At 78 to 80 degrees indoor depending on the humidity, that is normal. The valve will open to try to fully feed your indoor coil and it sounds like your head pressure is to low to force enough refrigerant thru the coil.

Day / Night HVAC is running cool air BUT the furnace is running 2


Strange. Does the thermostat control both the air conditioning units and the furnace. If not make sure the furnace thermostat is turned down to below 65 degrees.

What tempratues should be set on a honywell 4 cycle thermost during the summer months


As a general rule set your t.sat 20 degrees below outside temp. Leave at this setting 30-45 minutes. Move down until comfortable no lower than 10 degrees below outside for 30-45 minutes. Unit should cycle normally. If it runs continuously then raise the t.stat 3 or 4 degrees up. The national average is 75-78. I usually keep mine set at 80 during the day here in Georgia and 74-78 at night...

Cooling Problems


Your filter is clogged. Not the one at the bottom of the unit.The one above the unit. It is like a raditor coils, kind of a bear to get to. We have cats and dogs the filter gets most of the hair but not all.Usualy about 6 bolts to take out.The proublem will be at the bottom of the top filter.
