York Affinity Furnace Overview

York’s Affinity line consists of two gas furnaces: the Affinity YPLC, offering 80% AFUE, and the 98% AFUE Affinity YP9C. Winner of the Consumers Digest “Best Buy” award, the 98% AFUE YP9C is Energy Star rated and has a multi-position configuration.

"Affinity series"

Very Unsatisfied

Had this unit installed in April 2008. After reading all these reviews, there seems to be more problems with units from that year. We have had problems with the relay to the thermostat. Had it replaced, had problems with the blower motor, replaced, now it is not working again !!! Hvac repair says it is either the blower motor again or the circuit board, however because they work as a continual entity, both need to be replaced and they are going to trouble shoot it and see if it is just one or the other or both. This unit together with the a/c and all duct work was close to 12g. It has been 4 days and parts are ordered, however Supplier had none available and none could find the circuit board and are waiting part . I was told they went to the manufacturer to have one sent. Bad news to me…none available? Why? Is it a part that is has so frequently needing replacement that there is none available. Why wouldn’t anyone have these parts?? The unit is less than 5 years old. and I shouldn’t have to pay labor all the time. What happened to companies standing by their products??. Is this York so crappily made that they keep having problems? And for the money that was paid for it, there shouldn’t be such problems … at 90 / hr for tech labor… it is all a ripoff. After this bill I will have paid an extra 1300.00 for all the repairs to it !! what a load of Junk is that? I promise this – never again a york.

I have had Bryant, Lennox, Rheem furnaces in the past in different houses and everyone of these brands had to have service repair work done at some point. I have now owned a York yp9c modulating gas furnace for about 2 years and had a drain pan replaced under warranty that took 15 minutes for the service guy to replace which was free. Look at every brand and you will find issues if you want to but this York modulating furnace is just awesome. Evenly heats the home and I never know that is is running. Most of the problems that I see with all the new technology furnaces that are out there now is install error. Lots of clueless hacks out there installing. Buying a labor warranty for any of the new furnaces or a/c out there is wise. If the dealer doesn’t offer any just run! There is a good reason why they won’t offer a labor plan.

York owned by Johnson Controls. Heater broke after 2.5 heating seasons. York Will not admit the heater is a lemon and do the right thing – fix it. Central Air conditioner broke after 2 winters. Paid $6100 for both in July2009. Was hoping they would last at least 3 years. Bunch of corporate crooks.

"Best furnace out there"

I have installed over 1 million dollars of york equipment each year for the last 3 years. To this date I have only 2 warranty claims and they were on start up! To all you out there having problems with your york equipment 90% of warranty claims are install related!!!!!


"Great furnace"

5.0 rating
Very Satisfied

I put this furnace in my rental property, based on the high efficiency and promise that the modulating technology would help heat the house (in two units) evenly. It has done that brilliantly. The cold spots upstairs have been massively reduced, the first winter bill has been far less than last year, and it is also by far the quietest furnace I have ever seen. One of these is going in my primary residence next year.

Generally, the Affinity series is regarded as a high quality product across the web. Hvac-for-beginners.com gives the product line its highest rating for efficiency, comfort, and solid warranty. Gasfuranceguide.com also notes the product’s attractive design, quiet operation, and efficiency.

A consumer thread on hvac-talk.com carries more mixed reviews of the product. A handful of people express frustration with their Affinity furnaces. Multiple malfunctions, including odd noises and loud vibrations were among the complaints. Poor customer service with York service contractors also added to the list of issues.

Others on the thread report no problems with Affinity line and site poor contractors as the potential source of system issues.
