I am a BIG fan of Blind and Sons. A few years ago we had a furnace outage and as a customer of Blind they actually had a service technician come to our house in the middle of the night and loan us about half a dozen space heaters that kept the house at least at a temperature that the family or the pipes would not freeze at.
I WAS VERY IMPRESSED!!!!! To me this was going WAY above and beyond the call of duty. To add to this, they did not even insist on us committing to buy a new furnace from them as a condition of loaning the space heaters.
We did eventually buy a furnace from them and have been happy with it for the last 5 years.
Last May (2012) we also bought a new Air Conditioning unit from them and have been happy with it too!
