DDC for Lennox Equipment

Our controls team services, integrates, and optimizes Lennox commercial equipment, including rooftop units (RTUs), split and packaged systems, and dedicated outdoor air systems. We connect Lennox controllers to your BAS via open protocols and implement advanced sequences such as supply‑air reset, static pressure reset, demand ventilation, and economizer optimization. Where applicable, we interface with Lennox Prodigy controllers through BACnet for reliable point access, alarms, and trending.

Results include stabilized space temperatures, improved IAQ, reduced short‑cycling, and measurable energy savings validated by trends and reports.

Healthy Air + Energy Efficiency

Healthy buildings require both clean air and efficient control. We design ventilation to meet ASHRAE 62.1 targets, apply CO2‑based demand control ventilation where appropriate, verify economizer performance, and support higher‑efficiency filtration (e.g., MERV 13 when feasible). Our sequences minimize simultaneous heating/cooling, optimize fan speeds, and leverage outside air for free cooling to reduce peak demand and overall consumption.

FAQs

Can you upgrade controls without replacing my Lennox equipment?
Often, yes. We retrofit DDC to extend life, improve IAQ, and cut energy use while preparing your site for future upgrades.

Will this integrate with my existing BAS?
In most cases. We connect via BACnet or Modbus and provide tested point lists and graphics.

How much downtime should we expect?
We plan phased work and after‑hours cutovers when needed to keep your operations running.

What ROI is typical?
Projects commonly see 10–30% HVAC energy savings depending on baseline and sequences; we verify with trends.
