HVAC condenser cost

[Max Abend]

Not really a flipping question, but didn't know where else to post. FWIW, I bought this house from a flipper 😋

Long story short, despite paying $900 service for emergency AC service on Sunday, I arrived home from work last night to no AC. Assuming I need a new condenser, what is a reasonable price for a 2.5T or 3T unit installed in Nassau county NY (near JFK, so not that close to Manhattan, but not that far). I'm hoping to leverage the prior $900 to get a much better price on the labor portion, but I know we have one if the pricier servicers since they're one if the only ones that advertise regularly. They only sell Carrier and Daikin, which are fancier than the currently installed Goodman unit.

Is there any real savings to be had by purchasing the unit directly from an HVAC or plumbing supply house?
