For this job, the customer furnace would not light. So I proceeded to check the pressure switch hose line by blowing into it and sucking on the pressure switches. After I did that the furnace needed it came on, so I proceeded to also checked the flame sensor and found the readings are low. After I cleaned it, the readings came back to normal. I also noticed the inducer was shown sign of age, and was running on high ramp. I checked the amperage coming off of it, and I was reading 3.6. So I recommend the customer getting the pressure switch replaced and also having that Goodman Ventor replace And getting a GP plan. After showing them the price, they sign and gave the OK to have both parts, replace and getting the go plan as well As of right now, the customer does have heat again I did not find any other issues with the system
