If you own an older home in London, Strathroy, or anywhere across Southwestern Ontario, there’s a good chance your air conditioner isn’t doing what you think it is.

And the reason might surprise you…

It’s not too small.
It’s too big.

In this episode of Air Design Answers, Chris and Todd break down one of the most common, and costly, mistakes homeowners make when replacing their air conditioning system: improper sizing.

Because when it comes to cooling your home, bigger is not better.

-Why oversized air conditioners actually make your home less comfortable-The real reason your home feels cold… but still humid-How older homes create unique challenges that most contractors overlook-Why “just replacing what was there before” is usually the wrong move-The truth about square footage sizing (and why it fails so often)How poor sizing leads to higher energy bills, more breakdowns, and shorter system life-What a proper heat load calculation actually does and why it matters

Older homes aren’t built like modern ones and that changes everything.

From insulation gaps and aging windows to outdated ductwork and airflow limitations, your home has its own personality. And if your air conditioning system isn’t designed specifically for it, you’ll feel it every summer.

Uneven temperatures.
Sticky air.
Rooms that never cool down.

Sound familiar?

-Your AC turns on and off constantly-Some rooms are always hotter than others-The house feels humid even when it’s cool-You keep lowering the thermostat… but nothing feels right

These aren’t just annoyances, they’re signs your system may be sized incorrectly.

When summer hits, your rooftop HVAC system doesn’t get a warm-up—it gets pushed to its limit.

And every year, we see the same thing happen. Buildings that felt perfectly fine in the spring suddenly can’t keep up. Offices get too hot. Tenants start complaining. Systems run non-stop… and still fall behind.

In this episode, Chris and Todd break down why that happens—and more importantly, how to prevent it.

We walk through what’s actually going on inside your rooftop unit when temperatures rise, the small issues that quietly build up over time, and why they always seem to show up at the worst possible moment.

Todd shares real stories from the field, including a mid-summer breakdown that could have been completely avoided—and what it turned into once it wasn’t.

We also talk about what proper preparation really looks like. Not just “checking the system,” but making sure it’s actually ready to handle the demand that summer brings.

If you own or manage a commercial building, this episode will change the way you think about your HVAC system.

Because the truth is… rooftop units don’t usually fail randomly.

They fail because they weren’t ready.

And what you do before the heat arrives often determines how your building runs all summer long.

When should you replace your air conditioner—and can doing it in the spring actually save you money?

In this episode of Air Design Answers, Chris and Todd break down one of the most overlooked decisions homeowners and business owners face: timing your A/C replacement before the heat arrives.

Most people wait until their air conditioner fails in the middle of a heat wave. The house gets uncomfortable, stress levels rise, and suddenly you’re forced into a fast decision. But what many don’t realize is that this timing can lead to higher costs, limited options, and unnecessary pressure.

This episode explains why replacing your A/C in the spring can completely change that experience.

Chris and Todd walk through what really happens behind the scenes in the HVAC industry as temperatures rise—how demand spikes, schedules tighten, and why that affects everything from pricing to installation timelines. They also explain how waiting until summer often turns a manageable decision into an urgent situation.

You’ll learn:

• Why A/C systems tend to fail during the first real heat wave

• How spring gives you more control over replacement decisions

• What changes in the HVAC industry between spring and peak summer

• How timing impacts equipment availability and installation flexibility

• Why emergency replacements often cost more in ways homeowners don’t expect

• How to decide if your current system is a good candidate for early replacement

This episode isn’t about pushing replacement—it’s about understanding when timing works in your favor.

If your air conditioner is getting older, struggled last summer, or you’re wondering whether to repair or replace, this conversation will help you think through that decision in a practical, real-world way.

Because in HVAC, the biggest cost differences don’t always come from the equipment itself—they come from when and how the decision gets made.
