"Nothing but trouble"

1.0 rating
Very Unsatisfied

This furnace falls into the “lemon” category. I’ve had just about every part replaced, and some twice in 10 years. The first year or two, it ran fine. But, every winter it breaks down on the first below-freezing night. It’s literally like clockwork that it breaks down. Now, the blower motor has gone out. This is the second time. Next week, I’m having a different furnace put in.


"Water from black tubing connector hub"

Had a more deluxe model installed with the variable motor but within a few days the bearings on the motor went out and unit vibrated and grinded horribly. Got a new simpler replacement unit reinstalled which has worked for the 6 years ( although house was vacant for four) until suddenly during cold snap this week which required regular heating, a steady water drip out of the black plastic box pipe in the lower panel of the 9.c in the right upper corner developed. Easily 2 gallons a day. Set up a tube to divert. I thought I had seen it all. Where could all this water be coming from in this propane furnace? Is that amount of water formed with propane combustion? Ch8- o2. Why hasn’t this been diverted with a hose? Did installer forget? Is there a valve that is stuck? These damn units have become too complex and unreliable. Would rather go back to wood stove.

I bought my furnace Affinity ypc 9c March 12, 2010 The board has been replaced twice during the first year. The furnace performed well until January 3, 2016 when the sensors were cleanup. Now my comment will match what other owners wrote when year 7 is rolling. January 1, 2017 Blower failure. 01/06/17 new pressure sensor, new thermositor June 22, 2017 new gas valve. 09/08/17 cleaned sensor drain water from several hoses. September 30, 2017 Drain water from several hoses realigned drainage pipes. November 26, 2017 Drain water from hoses, installed 2 new switch pressure air, it did not make any difference. Technician with his mouth blow air in old pressure air and reinstall them, referring me to another outfit. Two hours later the hot air is flowing again in my house.

Owned it now for almost six years. In that time it is used only about six months a year and I have replaced controls and Igniter and now faced with replacing the heat exchanger. The company that installed does not deal in York anymore because of all the warranty issues-does that tell you something! Save your money or put a little aside to go to small claims court and put York’s feet to the fire.

"Quiet, responsive."

Somewhat Satisfied

I’ve only had the unit for about a month, haven’t actually compared before/after bills, but it’s quiet, and it does warm my condo in a timely manner. I never notice it running, but I can feel the heat start right away. Because I chose a better furnace than my contractor suggested, the rebates should cover two winter’s heat, at least.

Other Affinity YP9C Reviews

Comments in online forums regarding the Affinity YP9C appear to be mostly positive. A consumer on hvac-talk.com trying to choose between two York furnaces was told that the YP9C is better because it is a modulation unit, but both are good furnaces. On the same site, a post from a homeowner asking for opinions between the Affinity YP9C and a comparable Lennox unit found replies favoring the YP9C.
