Goodman with 2 thermostats, freezes in summer, no heat in winter

you need a 24 volt tstat, recommend a 2 heat 2 cool for maximum efficiency. not totally familiar with goodman products but it looks like this unit is communicating compatible but that's an extra dollar sign! Best Wishes.

If your going to pay that much just have them put in a new unit. It is not that much more and you can get free financing. All the repairman can do is guess and keep putting in new parts till it works. Had a new unit put in and it still didn't work found out it was a bad thermostat. But at lest we don't have the repair bills or high electric bill anymore so it paid for its self in saved money.

frist check that the thermostat and the mood is in right positions then check that thermostat give signal to Htr.if Htr is right ohms

is the gas turned on to the frunace? Is the switch on gas valve turned to on?

You say 2 to 3 years... I'm assuming the unit is older than that. Especially being r22. What about the first 10 years??? Normally you will get 400 to 500 sqft per ton of cooling, but, that depends on heat load calculations. If the unit wasn't big enough you would have had this issue 10 years ago, not when the system kept running low on refrigerant. At first guess I would say a 2 ton unit is not big enough but if it worked fine for 10 years...wuth all that in mind, if it were me, (a seasoned professional) I would spend 1800 to fix my 15 year old r22 unit before I spent $4000 on a new r410a piece of junk. Best Wishes!!

is the thermostat set for heat and you have power going to the unit correct

If you have a AC unit with electric or gas its doing what its supposed to do, let the pressures in the system equilize before starting again, If you have a heat pump its doing it there as well you just have not noticed. Anti cycling is a good thing, 4 to 5 minutes is normal.

look in your local yellow pages under air conditioner distributors for a local goodman distributor. A local company installed it but they all buy from a area distributor. call them with the previouse owners name and they may be nice and give you the name of the guy who installed your unit it is under warranty. be persistant good luck

Hello Does the thermostat have a display?Check emergency wall switch and curcit breaker all on.Fan on should at least run if power.

I would insist that Sears either have a Senior tech come out and fix it or return it to the state it was prior to them touching. Then call some one else. Have them involve the Goodman rep in your area.
