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.

If you’re a:

• Commercial property owner

• Property manager

• Facility manager

• Operations director

• Industrial building supervisor

This episode will help you understand how to prepare your commercial heating system before winter becomes a problem.

No sales tactics.

No fluff.

Just real HVAC knowledge from technicians who see what actually fails in extreme cold.

🎧 Listen now and make sure your building is ready before the next cold snap hits.

Episode 7 – Why Your Home Feels Cold Even Though Your Furnace Is Running

Your furnace is on.
It’s running.
But your home still feels cold.

So what’s actually going on?

In this episode, Chris and Todd from Air Design Services break down one of the most common winter comfort complaints homeowners experience — a house that never quite feels warm, even though the heat is technically working.

We explain the real reasons this happens, including:

• Poor airflow and duct design issues
• Heat loss from insulation and air leaks
• Oversized or undersized furnace problems
• Cold air return restrictions
• Basement temperature imbalance
• Thermostat placement mistakes
• Humidity and how it affects comfort

Most homeowners assume “the furnace must be failing.” But in many cases, the furnace isn’t the real problem at all.

Drawing from real service calls across Southwestern Ontario, we share practical examples of what we see inside homes every winter — and what actually fixes the issue versus what wastes money.

If certain rooms feel colder than others…
If your furnace runs constantly but the house never feels comfortable…
Or if you’re wondering whether it’s time for repair, modification, or replacement…

This episode gives you the clarity to understand what’s really happening before you make an expensive decision.

Listen now and learn why “heat running” doesn’t always mean “home comfortable.”

When your furnace stops working in the middle of winter, it doesn’t feel like a decision. It feels like an emergency.

But most winter breakdowns don’t start in winter.

In this episode of the Air Design Services Podcast, Chris and Todd break down the real conversation homeowners need to have before the coldest nights arrive: repair vs. replacement during winter.

We’re not talking theory. We’re talking real numbers.

• What a typical furnace repair actually costs

• When a heat exchanger issue changes the equation

• How age and efficiency impact long-term operating costs

• Why emergency installations feel stressful — and planned winter replacements don’t

• The hidden cost of waiting too long

Winter doesn’t usually create heating problems — it exposes them. A system that was already working harder than it should have been simply runs out of margin when temperatures drop.

We also walk through a real deep-winter failure case study and explain how timing affects cost, availability, and options.

If you’re a homeowner in Southwestern Ontario trying to decide whether to repair your furnace or replace it before it fails, this episode gives you clarity — not sales pressure.

The goal isn’t to push replacement.

The goal is to give you control before winter makes the decision for you.

🎧 Listen now to understand the numbers behind furnace repair vs. furnace replacement — and how to avoid being forced into a last-minute emergency.
