thank you,

and has the contractor discussed being able to find the coil?

Expert:  BillyHvac replied 10 months ago.

I need to know if a retro fit or if they are trying to find original...there is a big difference in price.

Expert:  BillyHvac replied 10 months ago.

do you not need help now?

Customer: replied 10 months ago.
Have not stared to locate coils as of yet. Need part number ?
Expert:  BillyHvac replied 10 months ago.

is this unit from mid 80's?

Maybe around 25 - 30 years old?

Customer: replied 10 months ago.
its 25 -30 years old.

Ok, you have a few options.

Replace the coil with a special order made to fit from Lennox. The original coil has been deemed obsolete for sometime now. Labor - $500, coil, $1,100+, r22 refrigerant $400 = Aprox $2,000

Order a generic coil that is coil to fit and modify. Labor, refrigerant, coil = $1,600

However I would strongly recommend not t invest that much money in a 30 yr old air hander. Especially when you buy a entire new air handler for the same amount of money SEE HERE

Air handler - $700, labor $1,000, refrigerant $400 = $2,100.

Now lets say I am low on a new unit and I add another 50% (1,000.00)

We are looking at $3,000.00......

So the question is...if you have a car that needs $2,100.00 of repair...or they offer you a brand new car for $3,000.00, which is the best deal?

After $2,100 in repairs you still have an old car...

My opinion is to not invest any money in a 30 yr old unit.
