When extreme cold hits Southwestern Ontario, commercial HVAC systems are pushed to their limits. In this episode of Air Design Answers, Chris and Todd from Air Design Services break down what real winter HVAC planning looks like for commercial buildings — and why most heating failures don’t start during a cold snap… they start months earlier.

If you own, manage, or operate a commercial building in London, Strathroy, or the surrounding area, this episode explains how small inefficiencies in airflow, combustion, and controls can turn into expensive shutdowns when temperatures drop.

We cover:

• Why airflow problems cause short cycling and premature equipment failure

• How dirty filters and restricted ductwork increase heat exchanger stress

• The importance of combustion analysis and proper gas pressure during extreme cold

• How control calibration and staging errors drive up energy costs

• Why rooftop units fail during cold snaps

• Redundancy planning and backup heat strategies

• Real-world case studies from warehouses, manufacturing plants, and office buildings

• The financial impact of emergency HVAC repairs in winter

• How to reduce downtime and protect operations

Commercial heating systems operate under heavy demand in winter. When outdoor temperatures fall below freezing, even minor HVAC performance issues can escalate quickly. Emergency furnace repairs, rooftop unit failures, gas pressure fluctuations, and airflow restrictions are common causes of mid-winter breakdowns in commercial properties.

Proper winter HVAC maintenance isn’t just about checking if the system turns on. It requires airflow verification, combustion tuning, heat exchanger inspection, control system review, and performance testing under load conditions.

In this episode, Chris and Todd share decades of experience working inside commercial buildings throughout London Ontario and Southwestern Ontario. They explain how proactive winter HVAC planning protects productivity, safety, equipment life, and operating budgets.
