Question about Heating & Cooling
SOURCE: My goodman heat pump has
After system has been running 10-15 minutes, the discharge air temp should be 18-22 degrees colder than the air being sucked in. If the air is more than 22 degrees colder then the problem is with air flow. Check filters, blower speed, make sure all vents are open, is indoor coil clean. If the discharge temperature is less than 18 colder, then the problem is with the refrigerant portion of the system (low charge, improper flow control of freon into coil) the key is if you have an orfice or a TXV (Thermal Expansion Valve) to control the flow of refrigerant into the coil. TXV's are known to fail with intermittant problems, however, most 10 seer systems do not use a TXV, they use and orfice which could have debris in it affecting the flow of freon. Hope this helps. When you rate my solution, please keep in mind that I am a technician that normally diagnoses equipment by checking it out in person. I do the best that I can with the information that you provide me on Fix-Ya.

No, heat exchanger is most likely cracked. Time for a new furnace. I cannot see your reply due to some tech issue w/ the site, so it may be a day or so before I can reply again. Please leave feedback for me if appropriate. Thanks

SOURCE: outside unit will not come on
could be the slow blow fuses in the disconnect box. check them for conntinuity if you don`t get continuity replace the fuses. check for power @ the contactor. the contactor is where the wires from the diconnect box attach to the ac. check both sides make sure your getting 240v be careful not to touch the wires ofcourse. if your getting power change the capacitor. may need a hard start for the compressor as well.
