This past week we started having trouble with our heating unit. The problem was we were out of town and did not realize that it had broken down. When we got home, the house was super cold and it was then we realized that while we were gone, the pilot light had went out.
The unit could have caught on fire and burned the house down while we were gone. Had we had the new Lennox iComfort® S30 to make us aware of the issue, we could have had it fixed immediately.
