For this job, the customer furnace was not coming on due to the pressure switch. So I blow into the hose line and I sucked into the pressure switch. After I did that the furnace immediately came on. So I recommended to the customer having a tuneup done on her furnace and talk to her about our Gold Plan Membership. And she wanted our plan. I created an estimate and they gave me the OK to have the office. Call them and schedule an appointment. As of right now, the customer has heat. I did not find any other issues with the system
