Re: [HVAC] Goodman 2 Stage HP Defrost

I bought 2 Goodman 4 ton heat pumps last year. IIRC the defrost cycle starts every half hour when heat is on and operating, but if there is no frost, it doesn't continue. I don't think 2 hours is a good idea if you are in an area that regularly gets cold.

I am set for 90 minutes now. I will see how it goes when I get back there, probably tomorrow.

My unit has not been in defrost in weeks now. Regardless of timer settings the coil temperature has not required it.

I think my unit tests for frosting every half hour, but only starts a defrost cycle if frosting has occurred.
