"They made 3 service visits before recommending a new one. I was already peeved by the multiple service visits that we paid for but their price point was decent for the furnace installation. They were all nice enough and it was nice that they thought they could fix the furnace instead of us having to buy a new one, but over $300 later and it still didn't work.  I will only use them again to keep the warranty on the furnace.
