For this job, I performed maintenance on the furnace. After checking everything, I found the collector box on the Goodman furnace was leaking I recommended the customer putting a new seal on it and they gave me the approval to get that fixed. After putting a new seal, I did not find any other issue with the system. The customer had asked if I could look at their humidifier because they didn’t think it was working. So I proceeded to check the humidifier and I found everything OK except the water had been turned off. And I also bumped the humidifier up. Told the customer if this doesn’t work, we would need to come back. Overall rating of this system is OK
