The Bottom Line
Lennox’s XC21 is a premium air conditioner in many ways, including available features and technological compatibilities, high-quality design and build, high-efficiency rating, and two-stage compressor. But if you're looking for a budget-friendly cooling system upgrade, the XC21 also comes with a premium price tag so it might not be an ideal option if you're looking for an economy air conditioner without any additional bells and whistles.
In Depth Review
Lennox XC21 Product Specifications:
SEER: Up to 21
ENERGY STAR® certified: Yes
Decibel rating: As low as 74
SunSource compatibility: Heating and cooling costs account for a large portion of your energy bills, so if you pair your air conditioner and furnace with a solar array, you could potentially save hundreds or thousands of dollars every year on energy costs. The XC21 is compatible with the SunSource Home Energy System so you can power your cooling system with the power of the sun.
Quiet operation: The decibel rating of the XC21 is as low as 74, and this is because it has many sound-dampening features. The most important is the SilentComfort noise-reducing technology, which is only available with premium Lennox air conditioners. SilentComfort technology includes a specially designed fan blade, thick insulation, and engineered vibration resistance to reduce noise levels.
Humiditrol compatibility: Humiditrol is a whole-home dehumidification system that you can pair with the XC21. When paired with this system, the XC21 offers superior climate control capabilities, doesn’t have to work as hard to keep your home at the right temperature on humid days, and will reduce your energy costs while keeping your family more comfortable.
The XC21 comes with Lennox’s best standard warranty, and this includes a 10-year limited warranty for covered components and a 10-year limited warranty for the compressor.
Comparable Models by Lennox
Model Comparison by Price: Lennox XC21 versus Lennox XC13
When compared with a mid-range model in the Lennox line like the XC13, the XC21 is substantially more expensive (by at least $1,000). However, the XC13 doesn’t have nearly as many perks as the XC21, including that it only has a single-stage compressor, a SEER rating of 15.5, and it’s not compatible with the same technologies as the XC21.
Model Comparison by Features: Lennox XC21 versus Lennox EL16XC1
The EL16XC1 is a mid-range Elite model, so like the XC13, it can’t compete with the XC21 in terms of features and compatibilities. For example, it has a single-stage instead of a two-stage compressor, has a SEER rating of 17 compared to 21, only has a five-year components warranty, and it doesn’t have the same SilentComfort technology features as the XC21.
Model Comparison by Tier: Lennox XC21 versus Lennox SL18XC1
The XC21 is the second best air conditioner that Lennox offers, so there aren't many models that can compete with it. The XC21 still comes out on top when compared to the premier series SL18XC1, because the SL18XC1 only has a single-stage compressor, isn't as efficient, and can't be paired with the Humiditrol system. In fact, the only model that offers more benefits and features than the XC21 is the XC25, which is Lennox’s top-of-the-line cooling system.
