"LX series diesel heating"

5.0 rating
Very Satisfied

Diesel’s Heating and Air is the best! We had the LX series installed July of 2015 and it’s like we have a new home.The salesman Tom Mendez was great, really knows what he is talking about. The installers Dave and Bryan were just as good. It was a pleaser to have them working in our home! Our house is now warm in the winter and cool in the summer!

"York disaster"

1.0 rating
Very Unsatisfied

After researching, I decided to go with a York LX packaged unit. I let the salesman convince me that poor reviews were from years ago and also saw on message boards that units were much improved. Our unit was installed 12/14/15. A warm front came through (mid seventies) so we turned the AC on – no success. The fan for the top of the unit (condenser fan?) was not working. After waiting for the part to become available, it was replaced. Since the warm front was gone, we needed heat. Turn it on, no go. Module on the blower fan no longer working. If you are keeping score, that is two major malfunctions in less than 20 days. The temps will be in the 20’s tonight and we’ll have no heat – for several days since those parts are hard to get for the brand new units on a weekend. Over $5,000 for a furnace that refuses to work for more than 4 straight days without a failure. We replaced a 30+ year old Rheem that worked flawlessly until the heat exchanger cracked. I guess I could look on the bright side and say that my last two units averaged over 15 years. 30 years and 10 months for the Rheem and a week and a half for the York. No way I would ever buy a York again and wish there was a way out of this nightmare.

"This unit seems like a great machine."

This unit seems like a great machine. I like the two stage. I wish the contractor would have explained the workings of the unit and informed me about the options of different profiles.

"LX Series furnace"

5.0 rating
Very Satisfied

Pleased with this unit. Model number YE31130E175B1605AP. Runs quietly and very efficiently. We had previously used wood for our main heating source and with this furnace our budget increased less than $25 a month. Much lower than we expected.

"November 2015"

5.0 rating
Very Satisfied

Replacement for a 15 year old Carrier Infinity furnace. So far we are very pleased. Technician told us our old 100,000 BTU furnace was too big for our house; replaced it with a new 80,000 BTU York LX Series TM9V furnace. The new furnace takes up a smaller footprint than the Carrier and is very quiet. Very happy so far with the performance of this new York furnace. The only concern: a name plate sticker appeared to have been removed from the front of the cabinet and was replaced with a York LX Series sticker. The manual referred to Johnson Controls but did not specifically state “York” furnace – generic brand?

Other LX Reviews

One user at GardenWeb.com describes the York LX furnaces as “nice”. The reviewer appreciates the compressor jacket which makes the unit quieter. Another comment from doityourself.com states that the York LX furnaces has the ECM feature which allows owners to get constant air circulation by running the fan on a low speed. This benefit is more noticeable in multi-level homes.
