Went for a maintenance call today for heat. Tested for static pressure system is over then rating by .1. All electrical components are passing for manufacture specifications. Did a combustion test is within range. Inspected heat exchanger no cracks/leaks were detected. Checked temp split and is passing for specifications. Did replace filter for customer. Cleaned flame sensor and pressure switch hose. Did noticed blower wheel has collected more dust, will recommend a cleaning. System is up and running before departure.
