"Absolute Disaster"

1.0 rating
Very Unsatisfied

Our York YP9C furnace was installed in October 2013. It broke down 3 times in the first 6 weeks! Since then, it has broken down at least 2 times each and every winter. So many parts have been replaced on this thing, many due to moisture issues, that I’ve lost count. Circuit boards, flame sensors, gas valves, you name it. The total cost of repairs has now exceeded the cost of the furnace, including installation! If not for the 10-year warranty and the extended service plan I buy from my local dealer every year, I’d be broke. I hate this furnace, I do not trust it, and it needs to go before next winter. Our York central ac unit is fantastic, never a problem. Do not buy a York YP9C!!!!!

"Good Unit – Few Issues"

4.0 rating
Somewhat Satisfied

Purchased a new “Scratch and Dent” unit 8 years ago which had been damaged during shipment to the supplier. After straightening out the cabinet, worked without repair. Very quiet and had few issues except for the condensate pan (clear plastic) which had leaked for some time. I later learned this is a common issue amount owners. The replacement part is made of black plastic which should be more durable and reliable. I was able to purchase the part on the internet and complete the repair myself in less than two hours.

"Poor Quality! Not Recommended!"

1.0 rating
Very Unsatisfied

Poor Quality! Not Recommended! I bought York Model No. Yp9c080 98% efficiency furnace in July 2014. The heater failed twice. The first failure occurred in 2016! It was no heat. Changed a sensor after spent around cad$300.00. In Nov 2018, the furnace malfunction again, no heat at all! I am very disappointed by the furnace quality.

"Lemon Furnace, Awful Service"

1.0 rating
Very Unsatisfied

I wouldn’t recommend this furnace to my enemy, or the York brand to anyone. The Flame Sensor needs to be cleaned which shuts down the heat, the door interlock switch needs replacing yearly which shuts down the heat. My Affinity furnace has had an error code since I moved into the house. When a warranty issue comes up, the service company tried to tell me that my warranty wasn’t transferable and that I would have to cover the $1400 for the main board and replacement thermistor. When York was informed that their warranty contractor was trying to charge me $1400, they did nothing. Only Mastergroup was honest with me. The only thing you should consider when purchasing a York furnace is how much extended warranty, and labor included you can purchase. Once my warranty is done and this thing fails again, I will never purchase a York product or have a York product in any of my houses again.

"Don’t Buy this Furnace"

1.0 rating
Very Unsatisfied

Furnace installed in Dec. 2013. Replaced wiring and circuit board in year 4 due to condensate damage. Went to start furnace for 2018 heating season, would not start. Replaced GAs switch and wiring (due to moisture again), worked for a couple of days, and now it’s not working again. Although parts are under warranty, shipping and labor are not. Would not recommend another York product based on this experience.

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.
