Why Lennox?

August 4, 2020

We love Lennox! (We’re not talking about Annie Lennox, although she is great too). Why should you consider Lennox HVAC products above any others?

While you may be tempted to want the lowest-price HVAC system, you already know this doesn’t translate to long-term value. Lennox systems are built to last and to deliver consistent high performance., but we don’t expect you to take our word for it! Instead, we’re prepared to give you an in-depth explanation of WHY Lennox air conditioners and Lennox gas furnaces are the best!

Lennox Air Conditioners

First off, we want to quickly explain that air conditioner efficiency is measured on what’s called a SEER scale (Seasonal Energy Efficiency Ratio). Basically, this is the calculation of how much cooling output you get, divided by how much electric energy you put in, in order to determine how energy efficient an air conditioner is. The calculation is done in terms of British thermal units and watts, but you don’t need to know that right now!

You just need to know that, the higher the SEER number is, the more efficient the system is. The lowest possible rating is about 7 SEER and the highest possible (technically, but very difficult to actually achieve) is about 25 SEER. Although... the Dave Lennox Signature XC25 Air Conditioner has a SEER rating of 26!

So now that we’ve got that bit of understanding out of the way, how does knowing this help you feel the peace of mind that Lennox ACs are the best?

Well, not only is there the fact we just mentioned that common SEER ratings are 13 to 18, while there’s a Lennox model that goes up to 26…

What's more, other Lennox air conditioners that are part of the Elite and Signature Series have many awesome features, in addition to the high SEER rating, that can save you hundreds of dollars per year. They also have variable speed motors whose efficient precision saves you money. They are the quietest on the market, too. This is because of vertical air discharge instead of horizontal, so that the operating noise is as low as possible.

Lennox Gas Furnaces

On the other hand, the energy efficiency of a furnace is measured by AFUE rating (Annual Fuel Utilization Efficiency). The rating is meant to represent the average efficiency of the furnace over the entire heating season. Similar to the SEER rating, the AFUE rating is energy output divided by energy input. For example, an “80 AFUE” furnace is 80% efficient, and a “90 AFUE” furnace is 90% efficient. The furnaces in the Signature Collection have up to 98 AFUE, the highest in the business. (Unfortunately, there is no perfectly efficient furnace!)

Also, high-end Lennox furnaces use General Electric’s variable speed inducer technology, which basically means that the mixture of air and gas fuel calibrates itself constantly in order for the fuel to combust more efficiently. These furnaces also use a secondary heat exchanger, to really ensure that the gases in the combustion chamber are used, not wasted!

Innovations and Awards

Overall, Lennox is always innovating to provide maximum comfort and efficiency. In fact, the top Lennox air conditioners and furnaces have been getting the “Most Efficient” award from Energy Star for many years.
