My in-laws received two quotes for central a/c heating units for two separate products. How do I know which one is better? The first product is York Affinity furnace 3 ton a.c/ honeywell humidifier. The second one is Lennox E Line Model XC-13-036 with a honeywell TB-7

Thanks
Marc

They are both good units.

What makes the most difference is how well it is installed.

Call customers that have used there service before to see if they are satisfied.

Check with the BBB.
