Heat pump not keeping up to set temperature on thermostat but never drops below 63 degrees whens its 20 degrees outside.

It may be getting low on refrigerant due to a small leak. I'd have it serviced soon. When running at less than peak efficiency it will much more often switch on the heat strips and they are not cheap to operate.

I have a Goodman Electric furnace, Model AR 30-1 that is not putting out enough heat. Could it be that the heating coil is going out? Air from ducts is lukewarm at best.

There are more than one set of electric coils in these units. You can test each one with an amprobe to see which one has no flow. Than it is a matter of finding out why. Sequencers stagger the starting order of coils in electric furnaces, could have one of several other issues!

Heater doesn't come on?

The electronic ignition system in a gas furnace is a modern development that allows more reliable performance than standing pilot furnaces, provides energy savings and contributes to better furnace efficiency (AFUE). With a standing pilot, found most commonly on older low efficiency furnaces (55% to 65% AFUE is not uncommon), a small gas flame is always burning and is known in the lexicon of American home repair as a "pilot light". The problem with this type of "analog" ignition is that it wastes energy by constantly burning gas and can sometimes be unreliable. These issues have led to the development of electronic ignition systems for mid to high efficiency furnaces that exceed the U.S. government's established minimum AFUE rating of 78%. The electronic ignition occurs typically in one of two ways:
  • Intermittent Pilot, or
  • Hot Surface Ignition The intermittent pilot system uses an electronically controlled high voltage electrical spark to ignite the gas pilot and then subsequently the main burners, when the thermostat calls for heat.
    The hot surface ignition system uses an electronically controlled resistance heating element not unlike a light bulb filament (and shown in the photo above), to ignite the gas burner.
    It is important to understand some of the other components of a modern furnace that you will encounter depending on the type of high efficiency furnace you have. Why? Because they can also come into play in repairing an electronic ignition furnace when it won't run properly. Let's take a quick review of the types of furnace designs and components found in high efficiency furnaces using electronic ignition.

    I have a 25,000 BTU hanging furnace, will this heat a 900sq foot garage that has been insulated.

    Here in Vermont we design heating systems to perform at -10 to -20 degrees. Depending upon how tight the doors and windows are, it may if your temperatures don't drop below 20 degrees. It may take a while to heat up and I would not expect any temperature over 62 degrees inside the garage. Maybe a 50,000 Btu heater? Remember the output may be 20% less than the rated input of the heater.

    My goodman furnace will not stay on and heat my home to the desired temp

    If you turn Tstat up does it heat the house? If it still goes off you have a safety switch problem. Chances are high limit switch. You could have a bad switch or the cooling coil could be stopped up. That will cause the furnace to get to hot and shut down on high limit. The limit switch it is the middle of the furnace. You will ahve to get a service tech out to check it for you. Ask for free estimate. Furnaces are very dangerous if not properly maintained. Rus

    Goodman heats but defrosts turns on before desired temp.

    Yes. The defrost cycle of a heat pump is actually turning on your airconditioning to heat up the condenser to thaw it out. During this cycle your electric strip heaters "should" be adequate enough to compensate for the a/c being on. At about 30 - 34 degrees outdoor temp there is not enough heat in the air to to adequately heat your home with the heat pump only. Some technitions will use an outdoor thermostat to turn off the heat pump when it is under 34 degrees outside. If you are to cold when its under 34 degrees intall more electric strip heaters.. But if you do this your electric bill may go up significantly.
    Welcome to the wonderful world of electric heat pumps (lol).
    Good luck.

    Goodman a/c works, heater will work fine then fan will stop

    you have a circuit board acting up. Try keeping the fan in the "On" position. It will keep the blower on all the time but it may work. There is a built-in delay not allowing the unit to come on after you reset it with the thermostat, wait three minutes or so to see if it comes back on. I still suspect a bad circuit board.
