Furnace broke down in the cold weather for my elderly mother who lives along and for whom English isn't her first language. Called Carrier and got a quote, except they wanted about $1,500 to replace a motor or $2,500 to replace the furnace, except the furnace was only 12 years old. Given the furnace's age, it seemed fishy and seemed like someone was trying to take advantage of the situation so ended up calling Cozy Comfort Plus who assessed the problem honestly, charged a lot less and fixed the problem within 30 minutes of showing up. Will definitely go back to Cozy Comfort Plus in future.
Added February 5:
3 weeks later, the furnace decided to stop working late at night and trigger the carbon monoxide alarm. The repair person from the initial Cozy Comfort Plus repair came, determined the furnace itself was a goner and ended up replacing the furnace with a new one, while only charging for labour due to the furnace's warranty -> all within a day, despite the weather being between -10 to -20C. While quite a hit to the wallet over the last month, really quite pleasantly surprised at all of this in the end. Hopefully a troublefree furnace for the next decade or two.
