sorry for such a dumb question but i cannot find out if we have a heat pump or AC.

I have attached the picture of the outdoor unit, and while i am searching on the internet i cannot find any details of this model. I have a ton of documents from the previous owner of the house and i am going through it and seems like the documents are of a different model (purchased this place 6 months ago)

any tips?

just a quick note: I replaced the original thermostat with a Sensi thermostat and out of caution selected that no heat pump during configuration. The original thermostat does not has emergency (or aux heat) option.

 

Was there a O terminal on the old stat?

 

That unit is a two speed condenser only. It's a 13 SEER unit using R22 refrigerant.
It's not a heat pump.

Pete I have not heard of any 13 SEER 2 speed units.
Two speed was 14.7 SEER in the 1990's and usually at least 16 SEER these days.

Are you sure it is 2 speed?

 

Quiet drive system - Features combination of swept-wing fan, composite base pan, isolated compressor compartment and two-stage compressor to reduce overall sound to a mere whisper.

I thought it was strange too unless the write up is incorrect.

It only has one contactor and it is a recip compressor. It seems like a single speed model. Do you think figure 6 accompanies figure 5?

 

thank you guys. i have a follow up but different issue. I will post it as a separate thread, but thanks to everyone here!
