Preformed a 20 point inspection on two split systems, both were operational and functional when powered on. Went through electrical connections on both systems and checked safety limits. Both systems electrical connection were good and within range nothing was over amping or drawing to many amps. All safety limits functioned properly and were operational. Static pressure on both systems were high, recommendations were made to the customer to address static pressure and ducting. Condensate drains on both systems were clear and draining. Combustion gases were venting properly on both systems and were no leaks in the flue vents. Over all both systems were in good condition, other than air flow and ducting which we addressed with the customer.
