Lennox Versus York Air ConditionersLennox Versus York Air Conditioners - Here is a Lennox and York comparison for their premium model air conditioner as requested by a reader of the site. Just off the top of my head, both systems are good systems. I would say Lennox had a slight advantage but the first-hand experience in the field gives most HVAC technicians the opinion that Lennox is over-engineered.

Lennox Versus York Air Conditioners

Lennox Versus York Air Conditioners - That is not my own opinion as I have heard this among other technicians that have worked on Lennox products. Additionally, finding parts for the Lennox is difficult as some Lennox parts are proprietary (as many manufacturers have proprietary parts) but can only be purchased through a Lennox dealer which makes them more expensive.  Despite that reputation, Lennox does make a good air conditioner system that has quality workmanship and quality materials and parts in the air conditioners Lennox produces. York has an excellent reputation for quality products also.

York also has some air conditioner condensing units that are very aesthetic and pleasing to the eye so York units can be very stylish and pleasing. That is not to say the Lennox units are ugly as they are not. I once heard a former co-worker refer to the new style Lennox units as looking like a spaceship.  As far as quality and workmanship both Lennox and York are good systems.

Comparison Guide for York and Lennox Air Conditioner Models CZH Affinity and XC-21


Lennox Versus York Air Conditioners - There are some differences in the two brands between York Affinity and Lennox XC21 air conditioner systems but the premium air conditioner models compare well aside from the Lennox system being a little higher in efficiency. Engineering and design of the systems, as well as aesthetic looks, is excellent for both models so the differences lay in the price and the quality of contractor doing the installation.

The Lennox high rating for efficiency does decline as the tonnage of the system rises. With a 21 SEER rating for a two-ton Lennox XC21 and 16.5 SEER for a 5 ton Lennox XC21. Keep that in mind especially if you need the larger size unit. Lennox also advertises that this system can be hooked up the Lennox solar electrical systems. These systems are called SunSource® which uses solar panels to convert sunlight into electricity. It is somehow tied into your for air conditioning and heating electrical system. It’s designed to trim a little off the electric bill.

Solar Sense?

Lennox Versus York Air Conditioners - According to Lennox, their solar power system is a grid-tied system. Theoretically, if your solar power system can produce enough electricity then the electric company will send you a check. It will take a lot of solar electric panels to do this feat. For some people, this is impractical as they do not have space for it. However, upon a cursory review, it does seem like a good system. A system that will save you money in the future.

You probably cannot use these in Historical districts. These units are energy efficient and anything energy efficient is banned in historical districts.  Additionally, you must live in an area that has net metering. From what is understood, many people do live in net metering areas.


Lennox Versus York Air Conditioners - The York and the Lennox systems have some comparable features and have a reputation for quality in materials and workmanship. There are some negatives that go with both manufacturers – see above – but this goes with the territory.

As always we must always recommend to the customer that the most important part of purchasing any type of HVAC equipment is not the name on the HVAC equipment but the quality of job the contractor does when installing the HVAC equipment. We are going to qualify that statement as I see a unit from an unnamed Asian country that begins with a big C that was true junk. The installing contractor needs to install the equipment correctly. Otherwise, you will not realize the efficiency the equipment is rated at.
