When you turn the heater on should the outside unit be running?
Yes if you have electric heat and it is a heat pump. A heat pump is essentially a AC unit that reverses itself to rejecting heat indoors or outdoors.

Turning on Christmas Lights . I turn mine on during Thanksgiving weekend . I live in the Chicago area, where a lot of people put up their lights in October, before it get…s bitterly cold. Some people turn the lights on as soon as they're up, but the majority of us wait until at least Nov. 15. Traditionalists wait until the day after Thanksgiving. And, even if they're still up after Jan. 7, don't turn them on!
Answer . The outdoor unit only runs in the AC mode(unless it is a heat pump). If you have the system off and the fan on, \nthe outdoor unit should not be on. You can run… the indoor fan only without harming the system.
What is wrong when thermostat is turned off and outside unit is still running for hours and the line on the unit is frozen?
This condition can badly damage your compressor outside by what isknown in the profession as liquid refrigerant slug back. I stronglyrecommend you cut the breaker off to the u…nit outside until thereason for this situation is found and fixed. As for the problems cause itself. There are a multitude ofconditions that could exist that would cause this. I will name afew but no way can I go into all I've seen in the field. . 1, And most Common cause is the contactor points are arc weldedshut and can't release to open the compressor and condensercircuit. If you do find your contactor points for outside unit arearc welded closed then look for what caused it to. Mostly you willjust find the coils outside are really stopped up or fan motor runsintermittently and shuts off by internal overload until cool enoughto cut itself back on for awhile which makes the compressor loadsever and amp draw extreme. Also rapid short cycling due to a low pressure or high pressureautomatic reset switch. Look for loose or inadequately sized wires that supply the unitsmain power as well. Just because a unit run load amps may beadequately handled by smaller feed wires doesn't mean that wire canadequately supply the very large amounts of currents to start up.This creates low voltage and surprise ! ( extreme contactor pointsarcing ) during the few seconds of motor start up initation. Also weak, or shorted run capacitors or also start capacitors ifyou happen to have it on your system. . 2 most common reason,,,, Shorted thermostate wires orimproperly installed thermostat. . 3 most common reason,,,, Outdoor condenser unit is wired wrongand is bypassing the thermostat control function to shut it off forone reason or another. Note: Be careful! (inductive loads) such as motors can knock youclean back to last year or worse so ( BE SURE THE MAIN POWER IS OFFCOMPLETELY) You may need a good electrician to give you a hand hereif you are even remotely baffled by what I've just told you.
Answer . the STARTER or capactor may be bad, i,d call a repair man
According to this web site: http://www.homeenergy.org/archive/hem.dis.anl.gov/eehem/95/950904.html shading your AC unit makes little difference, if any. Here's the deal, you …save money if the air an AC unit pulls in is cooler--the unit doesn't need to expend as much money cooling the air to the desired temperature. So here's the problem--shading the AC unit does not cool the air that it is drawing in. AC units draw in a very large amount of air and shading the AC unit shades only a very, very small portion of that air. So that very, very small portion of air is cooler than the air that is out in the sun, so you see very very small savings. But the vast majority of the air drawn into the unit was not in that shade but for a split second and does not benefit at all from the shade on the unit. So unless you have so much shade that a significant portion of the air drawn into your AC unit comes from that shaded area, then shading your AC unit will make only very little difference to the efficiency of the unit. \n. \nEven more, there is a danger in shading an AC unit that the shading material may block airflow to the AC unit. Blocking airflow to the unit reduces its efficiency. For this reason it is probably best to just not shade the unit at all--the potential problems associated with shading a unit (blocking airflow) are greater than the potential benefits of shading the unit.
The inside fan blows air through the ac coils to cool the air. Itshould be on a separate breaker or fuse circuit from the outsideunit. See if there is a fuse box on the side o…f the inside unit andcheck the breakers in the house main breaker box. Also standquietly beside the inside unit and listen for the fan motorrunning. If the motor is heard running then either the fan drivebelt has broken, or the ac coils are clogged preventing air fromflowing.
Should the outside fan of an HVAC unit turn on when the heat cycle is on or does it only operate when in the AC cycle?
the fan on the condesenig unit (out side part) of a hvac system will only run when you are in the cooling cycle, unless you have a heatpump , then it will run in the heating c…ycle also
Does it have the correct amount of refrigerant, are the compressor valves good, is the indoor coil plugged.
Call someone to repair the outdoor unit and the vents will blow cool air.
Only if the outside unit is a heat pump.
If your air conditioner is running outside by not blowing cold airinside through your vent, your indoor coil is frozen. You will needto turn everything off and allow the unit …to thaw out.
There are a few instances that will allow ( I am assuming when your saying inside unit you are referring to the the circulation fan for your building ) the inside unit to run.… Check the "mode" on your thermostat. Is selected to auto fan? this will allow the the fan to run continuously regardless if the air conditioning is cooling or not . If the thermostat is switched to the heating mode the furnace will be operating and the air conditioning unit will remain inoperative while the furnace mode is selected. Is the inside unit running and no cool air is being produced while the air conditioning mode is selected ? Contact your HVAC&R technician to trouble shoot the unit.

Running the AC compressor uses horsepower, and the truck does not have enough to overcome the loss.
compressor not running
Should you turn on your heater to protect the pipes or just the water flow when temp outside is 47 degrees?
When the temperature is 47 degrees, NOTHING is in danger of freezing !
An A/C unit is not required to run a furnace. You will want to make sure there are no gaps or missing equipment.
