My mom's 22 year old 4 Ton 10-seer Carrier A/C condenser is shot. Her
furnace is relatively new.

She wants to replace the old unt with a new Puron Carrier 4 ton
condenser.

One HVAC company is saying that they do not install new evaporator
coils
because it is unnecessary, and the efficiency will be around 12 or 13
if
the
old coils are used with a 15 seer unit. They say they have never had a
problem with leaving the old evaporator coils in.

Another HVAC company is saying that it is important to install new
coils
because the efficency won't be good, and also the unit will be under
more
stress with the old coils and will likely only last for 4 years.

Which of the two is correct?

Thanks,

J.


Beside the previous comments, a 22 year old coil is a leak waiting to
happen.


It's likely to outlast the new coil...
That said... you still have to install a new coil.


Bottoms up I guess float the oil out the top with the calgon **** spose take
your time...soak it...$$$=hours

still that old coil is gonna be all stiff an brittle and inadequately rated
as to test and working pressure while any of the new one will be dual
rated--(duh for lower pressure r22) as well as being listed for the higher
pressures you'll encounter w / 410
