I'm having our furnace replaced and have two bids. One is for Lennox G5036A and the other a Carrier 58PAV. Both units are 70K BTU. The Carrier prices out $300 more than the Lennox. I made sure the bids were apples for apples. The Lennox has better warranty than Carrier.
How many dealers in your area take care of Lennox or Carrier. When you need help and its cold outside how many options do you have? How many supply houses stock parts for your new furnace? Both furnaces are good pieces of equipment, I prefer to work on Carrier.
