York Affinity YP9C Furnace Reviews

"Best Furnace we ever bought!"

5.0 rating
Very Satisfied

We had to replace an outdated ge furnace that was about 34 years old. The team at Harmony Heating in Rockway, New Jersey were outstanding in recommending a replacement furnace that had a high energy efficiency. We are extremely satisfied with the York Furnace.

"Unreliable and not satisifed"

1.0 rating
Very Unsatisfied

Purchased 6 years ago and was not told of registration for 10-year warranty. Yearly maintenance service calls each costing $100.00. Needed a new motor (covered on 5-year warranty) and new gas valve which was out of warranty and cost $800. Contacted York and received no co-operation or consideration. Will never purchase York products again!

"Goodwill warranty not"

1.0 rating
Very Unsatisfied

Although it was my fault for not registering my warranty within 90 days to be eligible for the 10 year warranty, this unit has been plagued with problems. Recent major failure (main board) and no goodwill warranty considerations! Furnace was 4 months and 5 years past installation date but still within the 5 years of ownership. Would have thought they might stand behind their product and consumers with some kind of goodwill warranty but not a chance! In fact, they took a matter of minutes to reply too bad for you! Personally, I will never buy any product from York or Johnson Controls ever again.

"Piece of Junk"

1.0 rating
Very Unsatisfied

Moved into this house with existing (top of the line) York furnace less than 2 years ago. Have had a half dozen service calls already for heat problems. Could have bought a brand new furnace with what we’ve already paid out in service calls. Bottom line…Want a major headache? Buy a York furnace.

"Great furnace"

5.0 rating
Very Satisfied

Great furnace – quiet, heats my home quickly. I have an older home so the furnace had its fair share of workouts during the colder days during winter but maintained a nice temperature. I would buy this brand again in the future.

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.

Affinity YP9C Warranty

Product registration is required within 90 days for maximum warranty coverage. The warranty for the York Affinity YP9C furnace is comprised of the following:

  • Complete Assurance Warranty Pledge, stating that if the heat exchange fails within 10 years of installation, the company provides optional furnace replacement in lieu of heat exchanger replacement
  • Limited lifetime heat exchanger warranty
  • 10-year limited parts warranty

If not registered within 90 days, the parts warranty reverts from 10 to 5 years and the heat exchanger warranty reverts to a 20-year limited warranty. Labor and shipping costs are not covered by the warranty.
