Carrier Infinity 98 Furnace Reviews

"Very Happy"

5.0 rating
Very Satisfied

As I am a hvac Tech, I installed this furnace and heat pump on my own. From experience I would say that 90% of issues with any brand furnace is caused by poor installation and set up. With that said, that is why I installed the system my self. In my opinion, this is the best furnace on the market. It is efficient, easy to install and more importantly, very easy to service and maintain. The furnace has been installed for 3 seasons now and has been flawless. It is firing on propane with no issues. Installation is simple and set up also very easy. Have the Infinity touch control, highly recommend that this control be used with the Infinity series as it does give superior operation as compared to a standard thermostat and makes set up and commissioning so much easier and complete. If you have any furnace installed, make sure you have a responsible dealer install it as stated above, the install and set up quality will make or break your confidence in any furnace.

"STAY AWAY from CARRIER Furnace, especially from COZY COMFORT Plus"

1.0 rating
Very Unsatisfied

If you want to receive a defective Carrier furnace and accept that they have the right to refuse to replace a defective Carrier furnace even it is a new furnace that stopped running only one hour after installation, then go and buy a Carrier. Besides, read the back of your agreement carefully. Please please do not spend big money to get more headache like I experienced with their dealer and even with Carrier’s head office in Canada and in the USA.
