Came out here for a furnace tuneup on arrival tested static static was failing customer is well aware has gotten filters to improve static checked everything else out for the customer clean flame sensor took amperage on the inducer and the blower motor. Both were good took a look at the heat exchanger. Make sure there was no visible cracks holes or a huge amount of rust. Heat exchanger look perfectly fine only concern as of today. Besides static pressure is the blower being dirty, but customer is well aware of that. Thank you for choosing LBA services.
