Puzzling furnace quotes
I am working on replacing my 30-year-old furnace. I got a bit from contractor A....highly recommended by people I know, highly rated on Angie's list, etc. Quoted a Bryant 925t fully installed with humidifier at just shy of $6k. Second bid from local gas company, Carrier comfort at $3990 all-in or Ruud Achiever 90+ for $3295. Contractor B, despite being HUGE, no online reviews of any kind, anywhere. I'm puzzled by the staggering difference but also a little concerned about the lack of reviews on Contractor B. Is the Bryant that much more superior to Ruud or Carrier? I don't want to overpay, but I don't want a crappy install either. Any words of advice?
