I had a new 5 ton York heat pump installed for my house in 2005. It's had its fan motor replaced twice- once because the bearings failed and once because the motor failed. A pressure switch failed, and the main circuit board failed. The warranty covered the repairs for the first year or 2. The local service people say that the York unit is usually pretty reliable, but it's the brand they carry. They've been out 8 times to fix it. The circuit board problem took a couple of trips. I think the unit is a piece of junk and plan to replace it with a differentd brand the next time it fails.

I had york model yzh03611b heat pump installed in sept. of 2008 the first time it got cold out it would freeze up and quit working. Two years latter and over 20 service calls later and electric bills over 500 dollars it still freeze's up.York is horrible to deal with no one will answer the phone when they do you get the usual corp. run around. WHAT A NIGHTMARE.

York air handler condensor bad after only 2 years! I found out this is a common problem with this air handler unit, manufacturing defect, it developed a hole in the bend of the coils. York will not respond to e-mails but they did honor the 3 year warranty for parts only, but it still cost me $625.00 for labor. I will NOT buy anothewr from them. It is true about being very hard to find info on their units. I live west of Atlanta, GA in case someone wants to pick this apart.

This unit worked well for airconditioning. However I had a 12 year old Lennox which had not given me a moments trouble. My furance failed and I needed heat. I switched to heat at yhe end of Oct 2009 as it ws mild until then. I have had nothing but trouble and have been running on aux heat. I could have installed electric for MUCH less but I wanted to use less electricity.
It maybe poorly installed.

Quiet and super efficient, a high quality product. I bought the York because of the lifetime compressor warranty and all warranties transfer to a new owner should I sell my house. It uses a scroll compressor and 410 refrigerant. I have my set point to switch to my York modulating gas furnace at temps lower than 25 degrees.
I thought your review of the York modulating furnace mean spirited and rather ignorant. York has achieved the highest AFUE rating at 98%. Same methodology used to test other brands. It appears that you don't believe that the testing was accurate and fair. You resort to attacking York and it's executive's ethics and morals. Shame!!!

Editors Note - This subject has been discussed extensively among my peers and I am still skeptical about Yorks claim but I will not say it is not impossible to get that rating whether it is from AHRI or another testing agency and even if they used an acceptable test or not. The fact is the test for gas furnaces was in question by the National Institute of Standards and even among people in ASHRAE who actually set the standards for testing. The 98% claim was made before the accepted testing for modulating furnaces was put into place. Despite your comments I stand behind my comments about what I wrote and the consensus among my discussions with everyone is nearly unanimous. I work as a test engineer myself and so many of my peers are engineers in the HVAC and electrical industry. Gas has additives in it along with trash and moisture so the purity of the gas (what the people pay for) is not 100% gas. If I spend a dollar for gas but only get 97% pure gas then I can only expect to a maximum 97% efficiency. I loose 3% because of the trash and other stuff. Now measure the heat loss up up the flue and that decreases the efficiency even more. The math does not add up but giving York the benefit of the doubt I am doing some research about this matter and my opinion is yet to be determined concerning this matter. I have removed the caution alert from the review of the gas furnace. I would also like to say before being critical in the future for anyone give a technical reason why you think this is incorrect. This is a technical subject and I have clearly explained myself so I expect if someone was going to be critical about my review that they would disprove me using technical logic rather than hyperbole.

Equipment is good, installation and set up is critical to reduce interior noise levels. Copious technical literature on York website but unclear to a lay person on hot heat pump and 2 stage operation. to York will not talk to user directly on problems.
