Arrived on site per customer request to perform an inspection on the furnace. The furnace is a Coleman electric furnace located in the laundry room. Gave unit a call for heat from the thermostat. The unit kicked right on. Tested amp draw on all three heat strips. All heating elements were reading approximately 20 A. The blower motor was pulling 3 A. Took a temperature reading from a supply register and got a reading of 130 degrees. The filter is a 20X20x1 located above the blower compartment. The customer had recently changed the filter, and it was in good condition, however the filter had been installed in the opposite direction of airflow. Informed the customer of this and rotated filter for correct airflow. Customer also requested estimates for replacement of the two lav faucets in the master bathroom. Will email estimates to customer. Thank you for choosing CPI Plumbing and Heating!
