Lennox Furnace Review

How Efficient are Lennox Furnaces?

  • Up to 99% AFUE rating on top furnace models
  • Select furnace models are Energy Star-qualified
  • Award-winning furnaces for sustainable products

Lennox furnaces boast some of the best efficiency ratings among other manufacturers. Over 100 years ago, Lennox began selling coal-powered furnaces to the public but now provides environmentally-friendly furnaces with cleaner fuel alternatives like natural gas and electricity.

The Lennox Ultra-Low NOx Solution line of furnaces, in particular, offers 65% less nitrogen oxide (NOx) emissions than other low-emission furnaces from competing brands. In California, furnace installations that fail to meet the state’s NOx emissions are liable for a fine. Fortunately, Lennox’s furnaces meet these standards, so homeowners do not have to worry about pending fines.

All furnaces have energy guide labels to help homeowners compare Annual Fuel Utilization Efficiency (AFUE) ratings and energy savings. Lennox’s furnaces have AFUE ratings from 80% to 99%, offering homeowners hundreds of dollars in potential energy savings.

As a leading brand in energy-efficient furnaces, Lennox has award-winning products such as the Lennox SL297NV, recipient of the 2023 Green Builder Sustainable Product of the Year. Before investing in an energy-efficient furnace, homeowners should consider the upfront costs of furnaces from Lennox.

 

How Much Do Lennox Furnaces Cost?

  • Individual furnaces can cost between $4,200 to $15,000
  • Lennox prices are slightly higher than other brands

Lennox furnaces cost slightly more than other brands due to their high efficiency and added features. It’s important to consider that many different factors at play affect the final cost of a Lennox furnace, such as a home’s square footage, additional modifications, and furnace type.

To help appeal to all budgets, Lennox has furnaces with fewer features that are priced lower than their high-end models. The Lennox ML196E Gas Furnace is a single-stage furnace with basic features that offer energy-efficient heating without burning a huge hole in homeowners’ pockets.

Investing in a new Lennox furnace is a major decision, and homeowners should know what they’re getting in terms of features with their furnaces.

 

What Features Do Lennox Furnaces Have?

  • Compatible with Lennox’s iComfort S30 smart thermostat
  • SilentComfort technology for less noisy furnaces
  • Durable heat exchangers

Lennox’s innovative designs extend beyond energy efficiency. Their furnaces are built with durable stainless steel heat exchangers that help retain heat and come with blower motors designed with high-efficiency variable speed. The area where the blower motor is located is insulated to minimize loss of heat while maximizing efficiency.

All of Lennox’s furnaces are compatible with their iComfort S30 thermostat, which lets homeowners control their furnaces with single voice commands through Google Assistant or Amazon Alexa. Aside from its simple controls, the smart thermostat monitors changes to a home’s temperature to maximize a furnace’s heating efficiency. Even if a homeowner isn’t near their thermostat, they can control the settings through the iComfort app.

Most furnaces are known to be noisy. Thanks to their variable-speed technology, some of Lennox’s furnaces can be up to 50% less noisy than other brands. The SilentComfort technology includes a sound-absorbing surface on the burner chamber to ensure the furnaces are quiet.

All of these features may sound appealing, but are they protected under warranty?

 

What’s the Warranty on a Lennox Furnace?

  • Heat exchanger comes with 20-year to limited lifetime warranty
  • 5 to 10-year limited warranty on qualifying parts
  • 3-year labor warranty

Lennox stands behind their products through their warranties. The heat exchanger is one of the most crucial parts of a furnace, and Lennox offers a 20-year to limited lifetime warranty on their heat exchangers. Some brands offer a replacement warranty that isn’t available with Lennox, but their lifetime coverage gives homeowners peace of mind.

Besides the heat exchangers, Lennox’s furnaces contain other parts that help produce warm air. These parts have a 5 to 10-year limited warranty if they’re defective. Homeowners experiencing issues with their Lennox furnace can have an HVAC technician inspect it and submit warranty claims on their behalf.

To help offset the labor cost, Lennox offers a labor warranty for the first three years from the installation date. Homeowners can facilitate any future warranty claims by registering their furnace model number through Lennox’s website.
