    Before putting your gauges on a system, CHECK your filter!

    After 26 years I almost made a rookie mistake this morning. Customer called and my new system was iced up. I asked the usual questions: registers all open? Filter clean? Etc... She answered yes to all. Hmmm, I went ahead and brought a new matching air handler as previously I mated a coil on top of the existing (old) air handler. I wanted to be prepared for a long day.

    Well, spent 40 minutes there. It was an ECM with a circuit board w/ dip switches. Two switch changes with my tstat screwdriver and I was out of there.

    So, yes, to new and old techs, check your airflow!!!

    P.S. would have really sucked if I would've started tearing out the existing .

    You guys notice the adjustable TXV? I was surprised to see that, it is a 5 ton Goodman, supposedly new...Does Goodman ship that way?

    AIRFLOW AIRFLOW AIRFLOW

    I've said this over and over again. You've got to know how much airflow you're moving before you even think about putting your gauges on a system.

    If Goodman has a t in the model, it has an internal non adjustable txvs by danfoss.

    If it doesn't, such as a CAPF and you purchase a tx5n4, or tx3n4 kit, the kit included a sporlans adjustable.

    Or atleast as of 5 years ago when I was a Goodman dealer
