FURNACE MAINTENANCE
 Always Observes Early Maintenance
 One of the factors that is likely to cause the spontaneous failure of your furnace is the
coldest nights. However, you are capable of preventing this using a proactive approach
whereby you carry out the maintenance of the furnace at least once in a year.
 A quick Visual Inspection
 Administering of the eye test is the best tip before working on your furnace. One thing you
need to check in this case is the venting pipe. Ensure that it is securely fastened and angled.
Also, check the fastening of the other tubes like the drainage tubes. This should be securely
fastened. This is also the time to check for the chances of gas leaking. A smell of a rotten egg
is an indication of this.
 Thermostat Wire Inspection
 After shutting off power and removing the doors of the furnace, sta rt the maintenance
process by giving the wires of your furnace a slight pull. This is the only way you will realize if
they are fitted tightly and properly.
