Today heating checks and preventative maintenance was performed on three furnaces. The filters were replaced and the systems were operated and checked through a full heating cycle. The only deficiency discovered today is that the furnace on the mezzanine has a capacitor that tested below the manufacturer’s rating. Verbal approval was given today for it’s replacement. This will be replaced today under a service ticket. All three furnaces are functioning properly sans the above deficiency and there was no CO detected inside the occupied space. The maintenance checklists for today’s work has been completed and emailed. Thank you, Jon
