    Can anyone recommend 4 ton light commercial/residential compressor that uses copper?

    Can anyone recommend a good 4 ton light commercial/residential compressor that uses copper?
    I have heard that Microchannel are hard to repair and have a lot of issues.

    Thanks.

    Split unit? Easy to find units with copper tubing in their coils. Nortek brands and some Yorks will be the exception. Packaged units, gotta watch as more of them are microchannel. We did a 4 ton Carrier/ICP packaged unit with copper, Lennox tends to be microchannel.

    Tell us about the negative about mirco-channels.

    Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
    Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
    Use +Merv 10 air filter. -Don't forget the "Golden Rule"

    Do not know about Lennox package units...
    However the split system units (both indoor coils and outdoor units) are aluminum tubing.

    So far, they are working well... we will see...

    Split system.

    Can you recommend a good brand(or are they all the same?)

    I like copper over microchannel.

    Thanks.

    There is another option...
    Aluminum NON micro-channel coils...
    Lennox does this... conventional design, however aluminum round tubing rather than micro-channel design.

    Then there is the AlliedAir products...
    Lennox clones... good value for the $$$!

    Everyone has their own preference on what's good. I don't like builder models with no features. This summer we sold a lot of American Standard equipment, same as Trane. Even the standard line is relatively quiet and has high & low pressure switches protecting the compressor. Since our climate doesn't justify high SEER, this 13 SEER line is a good deal. But mid line of most brands would do you well. Again, watch York for MC and Nortek brands use it on all outdoor units, they were using them on heat pumps, not sure if they still do. They also use it on their A coils too.

    Last week, pulled and trashed a 2015 Nortek brand AC/coil... both MC... leaking like a sieve!
