Two men arrived on time, younger Technician very cordial, business like, older Technician (I think it was his Boss) was very quiet and unresponsive, a little grumpy but the younger fellow was excellent. They installed the furnace, explained what they would do and then they proceeded to do the work. They laid down a red carpet to protect the floor. The furnace was installed and tested. All of the important details were reviewed with me. Job completed in 2 1/2 hours, clean up, hand shake, with the young man, then they left. They left the area clean, the work looked to be well done. I was very satisfied.
