Comfort Shield Labour Protection

Extra Peace of Mind for Your New Lennox System

When homeowners invest in a new furnace or heating system, they often assume the warranty covers everything. In reality, most manufacturer warranties cover parts only. Labour costs for diagnosing and repairing equipment are typically not included.

That is why LSM offers Comfort Shield Labour Protection on eligible Lennox installations.

Comfort Shield extends your protection by covering labour related to qualifying repairs, helping eliminate unexpected costs during the early years of ownership. 

What Comfort Shield Adds:

Eligible installations can receive 3 years of labour coverage, providing added confidence that your heating system is protected.

Benefits include:

  • Labour coverage for qualifying repairs
  • No deductibles for covered service work
  • Fully transferable if you sell your home
  • Protection from unexpected repair costs
  • Peace of mind backed by LSM’s trusted service team
