5 Misconceptions about Lennox®

Lennox is always looking for great new contractor partners


Lennox® is hard to do business with because they only work with very large contractors.


Lennox® is always looking for great new contractor partners of all sizes. We've been growing our distribution model the past few years to make it even easier to serve more customers. Lennox PartsPlus® stores are being added every year to better serve contractors who need distribution facilities nearby to be successful. More than a few years ago, our distribution model restricted our reach because of a need to prioritize limited resources. Today, our competitors will tell you, Lennox wants your business, and it's true.

Lennox offers encouragement and resources to contractors


Lennox® wants to tell contractors how to run their business. That's not for me.


We do not and will not tell you how to run your business, but we will enthusiastically offer encouragement, coaching and resources to help you win. Don't let any competitor tell you otherwise. Lennox® is committed to providing world class training and other resources to support our customers and your personal goals to become more successful and profitable. Check out our training website and find out for yourself.

Lennox products are easy to work with


Older Lennox® products are hard to work on because of exclusive repair parts and non-standard wiring.


That was once true - but not anymore. About 20 years ago, Lennox product development teams made a commitment to building only products that use standard industry wiring diagrams, more universal replacement parts, and industry standard sizing protocols. And what we've built since then is a product line that many believe is the most technician friendly product lineup in the industry. If you find one of those old units, take it as a great opportunity for a product replacement sale, and give Lennox a call to try us out, we're confident you'll be impressed.

Lennox is easy to work with because of our lennox parts plus stores around the country


Lennox® is difficult to do business with because they have a small distribution footprint.


Over the past 6 years, Lennox® has added more facilities and more square feet of inventory space than at any time in our history. We have been growing our distribution footprint and market-by-market product and supplies availability as fast as anyone in the HVAC marketplace. We now have nine large regional distribution centers and over 200+ contractor facing distribution facilities. We call them Lennox PartsPlus® stores. Stop by and check us out.

Lennox customer service is here to help you with any questions


When I need help, Lennox® support can be difficult to reach, it takes too long on hold. Lennox doesn't care about making it easy for me to connect.


It has never been easier to do business with and communicate with Lennox. It's true that Lennox customer service is designed to align our support resources to the service of our Dealers first. We prioritize our systems to respond quickest to our repeat and regular customers. But that's not the whole story.
