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From insulation gaps and aging windows to outdated ductwork and airflow limitations, your home has its own personality.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.
