We had AFC come to our house on June 1 to clean our furnace. The crew arrived on time, were polite and clean, and appeared to do a good job. Unfortunately, something they did inside our furnace disabled our electronic humidifier. I noticed the problem several days later when the humidity in the house had fallen significantly.
The lady who took my complaint at AFC was completely unsympathetic to my problem, stating that their "policy" was to put me at the first open slot for someone to come and see about the problem. The lady must have used the word "policy" at least 10 times in our brief conversation, as if I should change my expectations because--by gosh--there was a "policy" to follow.
Eventually (days later) someone came and repaired the issue which was a wire they had jiggled loose inside the furnace. The repair technician claimed it was a "dirty connection," but since our humidifier is less than 5 months old, this was ridiculous.
I am pleased with the furnace cleaning and satisfied that the company repaired the damage that was done. I am not impressed at all with the attitude of the people at headquarters in dealing with complaints. If you should have a problem, I wish you luck.
