Just a quick size question on a Lennox condensing unit. Model number is: HS18-461-4P.
Is this a 4 ton unit?
3 1/2 ton
A 4 would be 511
A 3 would be 411
If you try to fail, and succeed.
Which have you done ?
Thanks... I forgot what they use as a code in there numbers.
Round down. 46 rounds down to 42,000 or 3.5 ton. Works on all the other sizes too.
