Was expecting the original service tech to be the one that would return with the replacement part. He was also the tech that put the unit in 16 yrs ago. He was going to finish cleaning the furnace. Miguel only replaced the part. Also, was not real personable. Made the comment about my furnace being16 yrs old and warranty was only 10 yrs. And why would I want to keep putting money into repairs. Was not impressed with his comment. We have had maybe 2 or 3 service calls since the unit was installed. If and when the unit completely fails, I'll consider replacement at that time.
