Thanks for that smartypants ^_^
Trane and American Standard are like the old Chevy and GMC. Look a bit
different but parts swap under the hood. They're expensive for the high
end models but high quality. The Trane and American Standard are like a
lot of units and sold only through authorized dealers. I've sold and
installed a lot of new Goodman, Armstrong and Ducane but repaired and
resold, rebuilt everything else. I did sell a new Samsung 4 ton 3ų unit
to a restaurant and it had an American made compressor and controls but
it worked very well and is still going after being relocated 3 times
when the business has moved. The systems me and my friend GB sold were
the systems sold as builders/contractors grade systems by the supply
houses. The different manufactures produce expensive high end, high
efficiency units that are as good as any but the less expensive units
will do the job and last a long time if they're correctly installed and
serviced properly on a regular basis. Unfortunately, the cheaper units
windup being thrown in by Billy Bob's AC Service and the things break
because of improper installation and Billy Bob is nowhere to be found.
This tends to cause customers to blame the equipment rather than the
moron who did the minimum amount of work just to make the system run. If
an installer takes the time to properly install the equipment, support
the line set and do a leak check with nitrogen then a triple
vacuum before charging the system with refrigerant, any AC/heat pump
will give years of service as long as the homeowner changes filters and
keep the equipment clean. I've done a lot of modifications to less
expensive systems to protect them from power surges and loss of
refrigerant charge and added high pressure safety switches like the
expensive units have as standard. The mods prevent a lot of system
failures and burned out compressors. ^_^
