Went for a maintenance call today. Tested for static pressure, system is passing when in cool. All electrical components are passing for manufacture specifications. Temp split is passing for system. Refrigerant levels is within range. Did clean condenser unit. As well replaced filter. System is up and running before leaving. As well did a furnace tune up. Pressure switch hose is clean and flame sensor. No co in home did inspect heat exchanger noticed wear and tear. System is passing for temp split. All electrical components pass for heat.
