HVAC repair or replace?

[Jonathan G.]

 We had one of our rental properties HVAC go out this weekend. Basically a fan motor froze up but the heat exchanger is also bad. An inspection of the other unit showed the same heat exchanger issue. Basically to get both heat exchangers replaced ( Labor cost only as the heat exchangers are still under the 20 year  manufacture warranty )and the broken unit up and running would be just under $2000 ($1887 to be exact) Both units are 16 years old. A reputable heating and air company has a special now to replace both units entirely including all heating and air components for just under $7500 (7352.57) we are holding onto the properties long term.
