Furnace King likely to have the most reliable service out there. I'm sure there are other good companies but our experience was with the company named above. They're sales rep is very knowledgeable and always available to answer calls. They have a call centre with an agent(s) ready to answer emergencies at any time. These folks are guaranteed to take care of you.
The only thing I can say that may keep people away is that they are not cheap.
Their price, however, matches the level of service. Top dollar for an A+ result.
If you you don't feel like rolling the dice, call Furnace King!
