I have WaterFurnace model ATV045D110CLT. It is 15 years old. The repairman says that it is $925 to replace a bad circulation pump and purge the loop. And then $425 to replace the second pump at the same time just as preventive maintenance. He also says to furnish and install a new condensate pump is $189. And to recover and recycle R-22 charge and weigh to factory specs is $599. Do these prices seem reasonable? And even if I do replace the one bad circulation pump do any of the rest seem reasonable? Thanks.
