Services

Lennox experts solve problems and preserve your business climate.

Full Protection HVAC Offering

This program locks in your HVAC service expenses at an agreed-upon rate, eliminating any potential cost escalations and substantially reducing paperwork. And since it covers repair and replacement of everything inside an HVAC unit, it also helps keep equipment performing optimally and lowers operational costs.

Preventive Maintenance

Performed up to four times per year, our 33-point maintenance check covers all major system components and provides a comprehensive rating for your equipment. This allows you to make repairs before major expenses occur, extending the life of your equipment and helping control costs.

Equipment Operation Check and Guided Setup

After each unit has been installed, we’ll perform a comprehensive 64-point check to ensure it’s working properly and take it through the basic and advanced guided setup processes. Any defective components will be repaired and a report for each unit will be provided to the installing contractor, general contractor and owner.

Commissioning

Lennox’ carefully designed commissioning process helps ensure your system is running efficiently and reliably from the start. Our technicians will verify and document key functions, including:

  • Correct equipment and options are installed and meet construction details
  • Lennox startup procedures are performed and sequences of operations are correct
  • Devices, including remote sensors, are correctly calibrated
  • System alarms are active, operation is correct and equipment safeties are functioning properly

Planned Replacement Program

At some point, it becomes more cost-effective to stop repairing older equipment and instead invest in new equipment that delivers higher efficiencies along with potential rebates and tax credits. Our team can help you proactively replace old and ageing equipment on your terms rather than waiting for an emergency situation.

Equipment Recycling

After installing your new unit, we’ll also haul away the old equipment safely and securely, decommission and recycle the used materials and provide the landfill avoidance reporting to meet your sustainability goals. Considering Lennox National Account customers replace, on average, 215 rooftop units per year, you could save up to 74.7 metric tons of CO2 annually just by using our recycling program.
