Had my furnace stop working on a Friday night, they were very prompt coming out Saturday- spent a few Hours working on it but were unable to get it working that day. The technician replaced one faulty part but didn't have immediate access to the 2nd part that had failed. He was very empathetic and apologetic, left a few space heaters over night, and made sure I was first on his list for the next morning when he could come back with the correct part.
Given that it was a weekend, and he had to make 2 trips out they were very reasonable with the billing.
I have used Pronto for my annual maintenance for the past few years, and this is the prime example of excellent customer service that has solidified my loyalty.
