Want to clean evaporator coils on Goodman A/C. It's a roof unit. the Heater, A/C evaporator and condesenor, both fans, are all in this unit. No way to get to the A/C evaporator to clean the coils. How do I clean them?

Look at the air handler (indoor coil cabinet)

have the central unit blower/fan cleaned as they block up from dust and other particles so that they eventually look like logs and do not move air like they should. Have the unit gas pressure tested for correct amount of gas

unit.

dead if the compressor is running and theres no cooling or frost on the evaporator you have leaked out all your freon only way to fix is call a pro about 600$ to fix

Hello, usually it is not a easy task. You must cut into the plenum where the evaporator coil is located and then cover the hole back up with sheet metal. Also, be very carfull when you cut into the plenum so you dont puncture the evaporator coil.

check fan motor of heater if woking if not check capacitor if deform it means cap. defective replace new one the same rating. clean air filter maybe it clog with dust.

have you cleaned the evaporator and outside condenser coils lately,try this first, then check unit pressures with a manifold gauge, also if compressor doesnt run but outside fan runs,it could be your compressor start capacitor,normally its a dual stage cap marked F for FAN and HERM for compressor and will have two "MFD" ratings and be either rated @ 370 or 440 volts A.C.

It could be a bad thermostat.When the unit isnt working does the tubing frostup? If you have heavy frost in the evaporator this could mean a leak or a dirty coil. Also make sure the filter is clean.

check to see if your evaporator coil needs cleaning
