I've had both Bryant (heat pump_, York (heat pump) and Carrier (AC
only) over the years without any serious problems. The only unit I
really had problems with (don't remember the make), was an ammonia
cycle AC that just had too many moving parts. They are basically a
refrigerator. If you can lubricate the fan bearing, all the better, but
the last two I've had are sealed units. I have lost refrigerat on one,
but it was a problem with sloppy installation. If they do have to open
it up, and recharge it, make sure that they install a silca gel
moisture trap, or you freeze up the expansion valve.
Both my sons are in the HVAC business...and over the years I have
learned to listen to them when they "talk" Heating and air
conditioning"... According to them there really is not much
difference in any of the major brands NOT a single one is more
reliable then any other... proper sizing, and proper installation
is much more important then the brand...
Just what I hear....and believe.. since they tell their mother the
