Our 12 year old 3 ton Lennox 10AC series Air conditioner compressor is
broken. Our HVAC guy and Armstrong dealer, thinks we should install
an Armstrong 213LE unit, 13 Seer, that uses freon, and replace the
evaporator coil for the 13 Seer efficiency. We're thinking to replace
it with a unit that uses the new R410A aka Puron.
1. Does anyone know anything about Armstrong Air conditioners,
especially the newer ones that use R410A?
2. Are the R410A type units any more complicated regarding
3. Since we are in the midwest where we only use the air conditioner
about 2.5 months a year, should we buy the minimum 13 Seer or go up
any higher in efficiency?
4.. We were just told that in addition to the evaporator coil, we
are now going to have to replace the copper pipe leading from the
furnace to the air conditioner because it previously had freon in it.
Is this really necessary, and if we don't do it, will it cancel out
We have overnight guests coming and its really hot upstairs. Please
