Awful Product - Don't Buy York

This furnace is the Affinity 9.c series and is less than 10 years old and for the last three years it has had one issue after another. I do yearly cleaning every year, but there is always an issue. Condensate collects in the box, the blower failed, the pressure switch or rollout sensor fails. And now they think the mother board is failing. Never again. I am replacing it with a Rheem!

This brand is a joke! Have had nothing but issues with it since purchased it in 2010. Will never own another one. Thinking about getting rid of it all together and the service man who installed it was a joke also!

The worst

I have had nothing but problems since I bought this brand new $4,500 furnace. I wouldn't touch York again. My installer even quit carrying York any more. I'm on a first name basis with all the repairmen now. It's New Year's Eve. I'm hoping garbage heap of a furnace makes it until the repair shop's open in 36 hours.

Avoid York at all costs!

Least reliable furnace ever! I'm replacing it after 10 years because the latest failure would cost $1,500 to repair (blower motor and inverter). Previously I've had to replace the main circuit board (many hundreds of dollars) and the water pump/actuator (another $100 or so). Consumer's Reports is right, do not buy a york furnace!

Class Action Suit - York Product

You will notice when you read the reviews that the 5 stars are from people who recently purchased a unit. Yes, the furnace works great in the beginning. When you get into year 7, the problems begin. I bought a York furnace 9 years ago and have had multiple expensive issues since that time. The latest repair was $3,000. On Thursday, I am looking at other companies to completely replace it. Too bad that I am still paying on it and will be for another 5 years. I am also part of the class action suit against York.

Learn From Our Misfortune

We bought a new York Affinity furnace and AC for a new house, and it broke almost immediately. We have owned it 8 years now, and have had over 6 service calls on it for faulty parts and breakdowns. The company covered some of the faulty parts, but not the cost of service which has totaled over $1900. so far, and we just had another fuel switch breakdown this weekend and needed another service call. We finally bought a service contract with the Rochester, NY heating business to cover all of these service calls - and of course we have to pay for the service contract. Also, we just received a letter about a Class Action suit against York because of all the faulty furnace and AC units. Do not buy a York furnace or air conditioner!

So sad. Why don't they just sell us an upgrade package to replace the faulty parts?

It worked great for two years. The burner and mother board were replaced under warranty in the third year. I have had seven HVAC people come from three different companies. Some multiple times. All I want is heat. Why don't you sell a patch or repair upgrade? I am not rich. I cannot afford a new system. It gets cold in the winter. Don't you care? Why not become "The furnace people with a warm heart"?

No heat furnace

Furnace was installed new in June of 2013 and has broken down twice. Annual maintenance was done 3 months ago but the first time it's turned on it doesn't work. I will never buy a York product again.

Solid furnace that lowered my monthly heating bill

I had to buy a new furnace at the beginning of this last winter season as my old one had given up the ghost. I researched for what felt like weeks (was really only days though) before I finally settled on a brand new York Affinity furnace. As soon as it was installed I knew I had made the right choice! After all my old furnace had put me through in its lifetime, my York is like a dream come true. Within the first month my gas bill had dropped almost a hundred bucks! I chose this model because it fit into my already existing gas pipes, I didn't have to do any modifications to get it installed. It had also won "most efficient" of Energy Star in 2014. It also has a 10 year warranty on it. Can't really argue with that and because it's new, I can call York to fix it if anything goes wrong with it. I haven't had this heater for very long so if there are any negatives, I have yet to come across them. So far, I absolutely love it. Just ask my friends, they are likely tired of hearing about it. Unless something terrible happens that York refuses to do something about, I would not hesitate to buy another of these units in the future.

Be prepared to pay more

Unit installed in 2011 in southern California (i.e., it doesn't get heavy use). I had the system maintained annually by professionals. Year 4 the system failed to kick on. 3 (three!) different parts had failed simultaneously. While the parts were covered under the warranty, labor to replace the parts cost 25% of the original unit price! Gasp! I called York several times to see if they'd do anything to offset such a high cost as this points to poor quality and potential for future problem, but they repeatedly declined. Buyer beware!

Nightmare of a furnace

This is my first time actually writing a product review but I felt compelled to warn other consumers. Purchased my York furnace in the summer of 2009. Problems started the first winter and have continued every heating season since. This morning just had the gas valve replaced. Sensors have been replaced every winter along with various "jiggling" of pipes and hoses. Yes, York offers 10 years of parts warranty but every service call costs me money. Three neighbors, including myself, installed these furnaces at the same time. Each one has been serviced multiple times, with various problems from sensors to master boards and now the gas valve. Do yourself a favor and run away from York furnaces.

York furnace and A/C

I had my 98% high efficiency furnace installed along with a new 14.5 SEER air conditioner on October 1, 2014. So far it is only one heating and cooling season old. It has performed as expected without any problems at all. I am amazed at how efficient both units are and how quiet they are. The only time I hear them is when it's really cold or hot and the fan has to ramp up to satisfy my heating or cooling needs. I did some research with regards to finding a good installer and I'm sure that has made a big difference in performance. I also got a ten year warranty which will cover most parts of my equipment. Time will be the big factor as to how reliable this equipment is. For now, I'm a happy camper.

Never again, a total waste of money

We have had a complete new system installed in our home in 2010, 2 zoned furnaces. The upstairs unit has problems every cooling season, the downstairs one every winter. So, since the upstairs one is a different York model, I'll write about that one separately. From season one, the downstairs furnace has been failing each heating season once or twice, as the pressure switches fail regularly. The installer company had to come out and replace these and then other electronic components each season, but the failures continue. Every time, it costs me about $200 - $250 in diagnostic fees. This is supposed to be the best furnace one can have? I don't think so. It is a lemon. At that time, York's warranty was only five years, now it's ten. So now that I'm out of warranty for parts, repairs will cost me 350 to 400 bucks each time at least, basically twice per heating season on average, judging by what has happened so far. I am going to throw this piece of junk out and will replace it with a totally new furnace from another manufacturer. It will save me tons of money in the future, but more importantly, it will save my nerves and give me reliable service, not headaches and a cold home for days while they schedule repair service! Stay away from York. Look at the pattern: for every happy customer, there are three unhappy ones! You have been warned!

York Affinity is junk

Bought 2 Affinity systems. The first one failed with 2 weeks, had to replace the control board. Then in the spring the AC failed, a bad TXV. The second unit keeps failing, the AC. Called York supplier in Philadelphia and he says they have a problem with compressors. The units are junk; think about getting replacements from another manufacturer. Very disappointed.

Blissful comfort

Had the York modulating furnace installed and couldn't be happier. It replaced a single stage 91 percent Armstrong which was working fine but we didn't like the temperature swings that come with a single stage. This York furnace does an amazing job at keeping a moderate temperature without cooking the house first then waiting for it to cool down before turning on again. We have installed it with the Honeywell Lyric thermostat and it works perfectly, as the modulating gas valve is controlled by the furnace. It simply needs a single stage thermostat to tell it the temperature that you want. It also works great with our steam humidifier, circulating the air as needed.

Very comfortable

I replaced an 80% efficient Trane with this Affinity 98% efficient furnace. I couldn't be happier. The modulating gas valve will modulate the heating up and down depending on the need in the house. It helps maintain a much more comfortable temperature in my home year round.

Ongoing issues

I moved into this house in October and it has a four-year-old Affinity 9C gas furnace, it's supposed to be the Cadillac of furnaces. I have had nothing but trouble with it. It keeps shutting itself down and I have to keep re-setting it so it will run. I have had service personnel here about a dozen times and they have done everything the York tech dept has suggested, including relocating venting, enhancing drainage, replacing the mother board, gas valve, wiring harnesses, etc. I'm still having the same problem. The error codes tell me it's a gas flow problem, but everything has been replaced! This is still ongoing. I am very frustrated and not impressed with the product so far. I hope they can find the problem and change my mind.

Heart-wrenching disaster.

I am having trouble writing this review, because I feel like the biggest loser. I didn't do my research and bought a product that has been very unreliable. I'm stressed and tired. During the furnace's heating cycle, the burner shuts off and the fan continues to run, blowing cold air. From day one, I've had to contact the technician who installed it. It's year five and the thing still has this intermittent issue. He wasn't able to figure it out, so out came the rep. He was also puzzled by the issue. I've got three young children and this furnace has added so much stress to my life. I don't know where to go from here. Tomorrow I'm going to call the rep. Again. I'm not a religious person, but please god help me!

York modulating furnace provides awesome comfort

We had a new York modulating furnace installed and our home is more comfortable than ever. The even temperatures and the quiet running cycles were very important to us. Not really knowing how comfortable and quiet it would be until it was installed, we are very satisfied.

York modulating furnace.

Replaced a 10-year-old Carrier 2 stage with ECM motor. This furnace is much quieter. The master bedroom is directly above the furnace and I hardly know when it's on. It's very efficient. I did not need a special modulating thermostat to run this furnace. All the other furnaces I checked needed one, at a very high additional cost. I could not be more pleased.

Expensive piece of junk

Furnace has been in service less than 2 years. This is already the second service call. This time it is going to cost us over $600.00 to fix this piece of junk. Switched from oil to natural gas to save money. Should have stayed with our old, reliable oil furnace. Do not buy this lemon!

After 75 years, worst furnace ever

In the six years that the furnace has been installed, I have had the contractors replace switches, mother board, gas valve, igniter, etc. Charges have reached over a thousand dollars. In my previous new home with a Trane furnace, I never had a service call. I am very disatisfied with this new York furnace/AC.

Utter nightmare for 7 years!

We replaced the 50-year-old furnace because parts became unavailable. Even though it broke infrequently (every 7 years or so), we couldn't risk it. So, the York. Reviews looked good. They sold us on the air cleaning unit. From installation on, it was a nightmare. Didn't work the first month. Didn't work after that. Techs came out every week, sometimes every day. Water was pouring out of pipes into the crawlspace. Mold developed in the crawlspace (had to get encapsulation and mold removal, $10,000). Back to the furnace itself - they moved water drainage to a bizarre system where tubes run up my wall, around the ceiling, into the washing tub! And still, that didn't work either. 1. Had the board replaced, and fought York to honor that warranty. Finally they did, but total labor costs to us the first year were in the thousands. 2. Had other parts, one after another, replaced. 3. The water drainage flooded itself and rusted out everything again and again. Water leaked out of the thing all over the floor. 4. It doesn't work better than it did. It's just that we pay and pay and pay, like idiots, only because we can't find another furnace that anyone really likes. All the furnaces look like the same thing could happen, from reading reviews. Now, we have to get a new one. Furnaces are only supposed to last a few years, right? Certainly not 10 years or 15 years. It can be fixed this time - but at a cost half that of a new furnace. Why don't we all just buy a new furnace every few months? Is that what they are aiming for?

Dual Fuel Gas Furnace-Heat Pump

Apparently York doesn't care who sells their equipment until you have tons of complaints about an installer. I was a victim of a terribly poor installer. The technicians installed my furnace and heat pump three times before it came close to a correct installation. It's my fault for taking low bid. Just remember that the next time you're in an elevator in a building. It was low bid! We started off at $6400. Now that I have had the system for almost three years I have out spent the original savings. Originally installed without a txv valve. Cost: $330 to find this out. At the start of the second cooling season No Cooling. Cost: $675 to repair a small copper bleed line left laying on a larger copper line inside the heat pump apparently at the manufacturing process. $325 1st visit to recharge it (couldn't find a leak), $350 on the 2nd visit (3 weeks later) to recharge and repair the leak(they wanted $500 until I complained that it should have been found the first time). Christmas eve 2013 it quit heating with outside temp at 15 degrees. $160 for the first visit to get it operational. Needed a condensation chamber on the front of the furnace that was leaking on the burners and some incorrect wiring as originally installed. $142 for the second visit to replace the cracked condensation chamber and the igniter. Parts under warranty but not the labor. That's a smidge over $1300 that I have spent on this junk so far if you're keeping track. If you still want to buy a York then I highly recommend a thorough and complete check of the hvac installer and put back a couple thousand to handle repairs that you're sure to need.. I will never purchase another York product. They didnít respond to any of my inquiries on their website either.

Tremendously dissatisfied!

We purchased a York Affinity modulating furnace, model yp9c MP,in 2009. We have had three frustrating winters with it. Have already replaced the mother board, inducer motor and parts for gas jets. Have also paid for numerous service calls. The installer never returned our phone calls the first winter so we've been using a different furnace repair company. We've tried to email York several times, but the email pops back to us saying the address failed. I would never buy a York furnace again. What a piece of junk.

Excellent Product, But Installer is Key!

We built a new home with a York system and used it with only 2 service calls over 16 years. After selling that house and building a new 4750 sq.ft. custom home, we went with a York Affinity Dual Fuel (heat pump with propane furnace) System. We have been in this home for over 7 years and are very satisfied with our York system. We have never had any trouble with it and our York dealer/installer is top-notch. The same technician installed in both homes and is a career heating and cooling technician. He is in his early 60's and only services the systems he installs, no others. What's that tell you. I say this because, I think the experience, knowledge, and reputation of the installer is of utmost importance. This has proven true with my 2 York systems over the last 23+ years. I would purchase the same Affinity series heat pump and propane furnace again. We love the extra warmth of the propane when the heat pump switches over. Our temperatures range from 100+ in the summer to below zero in the winter and the system always handles everything very well. Only using between 250 and 300 gallons of propane per year which includes the kitchen use. The electric side of things tops out at about $300/month in summer ac months. Less other times of the year. Very good for a 4750 sq.ft. house with 2 full kitchens and two electric 50 gallon hot water heaters. I hope this information is helpful.

Affinity series

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.

Great furnace

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.

Best furnace I have ever owned in 50 years

I have never been more comfortable. This York furnace runs longer and slower eliminating any airflow noise, drafts and has greatly reduced my utility bills being 97% efficient. Apparently, the furnace matches its capacity to heat loss of the house. All I know is I have never been more comfortable and the unit has operated over 2 years without a flaw.

Never worked from day one

Bought this YP9C120D20MP11 heater in 2009 and had it serviced 7+ times for the same problem. The unit would blow out cold air for hours and never shut off. My dealer tried to fix this heater 7+ times with no success and he never got any help from York. When I called York direct all I got was a rude answer from there service manager Bill March. One time he laugh at me on the phone. I am very disappointed that they think this is a funny matter. My family will never but another York product again.

Good Equipment

Most of the complaints are caused by poor installation and not product quality. Excessive noise, having to remove screws to access a filter or being charged $400 for a furnace that is available with a 10 year parts warranty are all examples. Most contractors make their job as easy as possible so they don't offer extended warranties which in the case of York is a factory warranty. I suggest you ask questions about the contractors professionalism in effect insurance, training and technical experience. Stay away from the one man business. We are very happy with York products as we have been using Affinity for years and will put them against any other unit. If you want to pay for a name then maybe Trane is for you.

York 80% Efficiency Single Space Combination 2.5 Rooftop Heat/cool System

Within the 6 years we have owned this York d1np036n05606 unit it has been serviced 4 times. The parts always seemed to break down after the warranty expired so that meant we had to buy them again or pay a good price to have the unit repaired. When we purchased the York; we were told that all we needed to do every 3 months was to remove the filter. The so called easy way was not true it was just a lie. In order to replace the filter we must take a panel of the machine the furnace requiring us to remove multiple screws. Plus we found out there is another filter we must replace at the same time which is at another location and it also requires removing additional panels. We live in a cold freezing winter state and really do not want to be changing filters during that type of weather! We bought York unit because it was supposed to be a number one brand on the market and to me it should be listed at the bottom of the list. I would never buy a York furnace again!

Simply Awesome!

This is by far the best furnace that I have ever had. I use a Bear Media MERV 13 filter in the unit and I use a 1" filter on the return air. This unit heats my home perfectly and the air quality with the two filters I use is outstanding. I purchase the Bear Media MERV 13 filters from Amazon for $56 for a 2 filter pack, and I puchase the roll of 1" filter from Grainger for $120 (which will last me at least 3 years per roll). I cut my return filters from the roll and replace them once a month.

York is good by me.

I have a York Affinity two stage gas furnace and central air conditioner that was installed in 2006. To date, it has been totally problem free. I have both units serviced once a year. Most of the bad mouthing of York products seems to come from ignorant home owners who don't realize these new high efficiency furnaces need regular maintenance and no brand will be as reliable and maintenance free as models built 30 years ago. If you want high efficiency, you will pay for it, both in new cost of aquisition as well as maintenance and a shorter service life. Such is progress.

Very Expensive Piece of Junk

York Affinity Furnace top of the line and everything is breaking on it from 5 Pressure Values so far seems every 4-6 months it goes, new Mother Board because its so high tech it can't figure out how to run properly and now a new blower motor. do not buy this furnace

Installed Correctly = works great!

York Affinity Furnace - 97.5% efficient! Awesome. It is so quiet and even. I talked to a friend who has been a lead technician in the industry for decades, and he recommended York. Said it was in the top brand category, and uses a heat exchanger that is much more durable over time than some other brands. I've had friends with bad contractor experiences, but my contractor was awesome. Find a good contractor who sizes the equipment right, and your York will probably work just as well! Good luck!

I have installed and repaired all brands. They all have issues. My new York yp9c100 is a 98%er. also installed complete a/c unit. Two years gone but not one problem. We sometimes blame the equipment, but in fact, some contractors have not a clue on proper installation practices. In addition, to troubleshoot a poor installation is hard. My advice, (30 years as a contractor-retired) is do not go with lowest price. You have to live with this system for many years. Ask other people about your so-called expert contractor. Not the ones he gives you. If no one in your area knows him, thereís a reason for that.

Would not recommend

Had 98% effic. Affinity furnace and A/C installed in Aug 2009. Within 2 weeks, had to come back and repair A/C unit not welded properly, leaked all freon out. Late October, had to return and repair furnace. No heat, would not turn on. Now, it would not turn on, had no heat to wake up to. Service tech came after 1pm in the afternoon, repaired the problem and then adjusted the modulator valve or something so that the whole burner would not go on when not needed. So to date, I have used more gas this year than I did last year with a 15 year old furnace. The tech also noticed another problem and has ordered parts.. not very happy after spending $9000.00 Would not recommend.

@ years old and problems contiue

I bought a high efficiency Affinity. In 1.5 years, we have replaced the inducer motor, pressure sensor, reconfigured vent pipes, replaced mother board and it still fails to work as needed. Have had service out numerous times for $1000 in cost. Will try to replace under lemon law.

Love it

Recently had a York yp9 variable speed modulating gas 98% eff furnace installed in my house I can barely hear the furnace running. I have read some of the complaints about others it could be the company that had installed it. These guys were very proffesional clean up after themselves. Someone wrote about the radiator thing that would be your coil which provides your ac in the summer warm air running accross does cause condensation and needs to be clean but I read its like that for all manufacturers. My neighbor is very envious of what I have and may want one of his own now.

York Affinity

Last month I had a York (now owned by Johnson Controls) Affinity variable speed furnace installed and it has been a great furnace thus far. The 95-97% efficiency is tremendous and it is far superior to the Rheem it replaced. The variable speed blower/modulating fan allows the heat to be distributed evenly and relatively quietly as the fan is not overworked. The furnace is very quiet, although in the morning when it first goes on after having the thermostat turned to 60 degrees in the night, it is audible, but only for a couple of minutes as the fan is on high. After the temperature set is reached, it is on cruise control, in effect, and is hardly audible as it continually maintains the desired level. The venting is interesting as the carbon monoxide is vented through pvc pipe which is under the house and then discharged through a hole in the wall, while the water is discharged via a small sump pump into the garage sink. The furnace is fine and the noise level is extremely low. The efficiency qualifies for tax credits and it is the best furnace we have owned.

Do Not Buy York Affinity

I purchased a York Affinity 2-stage furnace from an authorized York dealer in Skokie, il. The unit has never functioned properly. It shuts itself down before bringing my home to temperature. My dealer made more than a dozen trips to my home and never fixed the problems... although he always charged me for the privilege. In 2 years, I have been charged over $1000 in service fees, and my furnace still does not work. After writing a letter to the Better Business Bureau, I received a call from York's midwest sales manager. He agreed the furnace was a lemon and has agreed to replace it, although with a lesser model that doesn't even show up in York's full line furnace brochure. The dealer, however, says he will charge me another $1000 to install it. I am beyond being aggravated with these incompetent rip-off artists. I am contacting an attorney.

York Affinity

I purchased a York Affinity. It is reliable but extremely loud. I ended up having it permanently set to never go into the second stage because it would wake us up at night. Unless you have very large house, I wouldn't recommend it.
