How a faulty thermos turns your home into an oven
A high-performance double-glazed unit is much more than just double glazing. Between the two panes is a argon gas which blocks heat transfer, as well as a Low-E film which reflects the sun's infrared rays.
When the seal fails, the argon gas escapes and is replaced by ordinary air, which conducts heat much more efficiently. The Low-E coating, however, loses its effectiveness. The result: your window becomes a veritable highway to the sun's heat.
⚠️ What few people realize:
A single south- or west-facing window with a faulty double-glazed unit can let in as much heat as a space heater left on constantly. Multiply that by four or five windows in the house, and you'll understand why your air conditioner never shuts off.
The calculation that will shock you
Let's take a concrete example for a typical house in the Montreal area with central air conditioning:
Current situation
Defective thermos
Air conditioner running 18-20 hours a day during periods of intense heat.
Summer bill: 250-350$ / month
After replacement
High-performance new thermoses
Air conditioner that runs 10-12 hours a day and reaches the temperature faster.
Summer bill: 170-230$ / month
Over a 4-month warm season, it's easily 300 to 500$ savings — just on the air conditioning side. And that doesn't even include the heating savings in winter, where the same efficient thermos keeps the heat inside.
You are also protecting your air conditioner
An air conditioner that runs 20 hours a day wears out much faster than one that runs for 10 hours. By replacing your thermostats, you reduce the load on your entire system.
Result: your air conditioner lasts longerIt requires less maintenance, and you avoid the premature replacement of equipment that costs thousands of dollars. It's an invisible but very real saving.
