Tips to Improve Promo Code Success Rates at Lennox

Finding a promo code for Lennox is easy, but getting it to work can be a challenge. Here are our top tips to help make sure your code works at checkout.

  1. Copy your code exactly as it appears. Most promo codes are case sensitive, and we’ve all made typos before. Don’t risk entering in your code manually.
  2. Read all the details of your code. Often a promo code will have some kind of restriction. This can include a minimum spend amount, exclusions on certain items, or membership requirements. Make sure the code you select applies to your order to avoid being disappointed at checkout.
  3. Try featured codes at the top of this page first. The higher up on the page a code appears on BrokeScholar, the more likely it is to work. We use a ranking model based on coupon source, time decay, and user feedback to push the best codes to the top.
  4. Avoid one-time use codes. If you find a code that looks like a random string of letters and numbers, it is likely a one-time use code. Don’t be surprised if the code has already been redeemed and fails at checkout. Codes that include common coupon keywords like “SAVE”, “SALE”, and “WELCOME” are more likely to work.
  5. Shop during the Holidays. Brands like Lennox typically offer the most promo codes during the holiday season. If you can wait, shop during Black Friday or Cyber Monday for the best deals.
  6. Speak to customer service. Having issues with your code? Many online retailers like Lennox have 24/7 live support. Don’t be afraid to ask for help– sometimes customer service will even give you a new, working coupon code for your efforts.
