For this job, the customer was having a problem with her house, not heating. So I proceeded to check the furnace and found the igniter fell to light. So I recommended to the customer having their igniter replaced and she gave me the OK to have that part done. After I had that part, replaced the furnace ignited and the burners lit up. I checked the operation of the furnace and found it working properly again. I did not find any other issues with the system Overall rating for the system is good. The customer has heat.
