Fatal mistake: why choosing an oversized wall-mounted air conditioner can ruin your comfort in Longueuil

Power isn’t always synonymous with comfort: Beware of oversized wall-mounted air conditioners in Longueuil

At AirGreen, we have often encountered homeowners in Longueuil convinced that a very powerful wall-mounted air conditioner would provide them with optimal comfort. However, this misconception can lead to a costly and uncomfortable mistake. Through our real-world experience, including a recent intervention involving a 24,000 BTU Fujitsu Halcyon wall-mounted air conditioner in a Longueuil condo, we have seen firsthand how choosing the wrong power size can negatively affect your daily life. Here’s why and how to avoid this common mistake.

The unexpected consequences of an oversized wall-mounted air conditioner in Longueuil

Opting for an oversized wall-mounted air conditioner leads to several unwanted effects that go far beyond simple temporary discomfort:

  • Frequent short cycles: An oversized air conditioner cools the air quickly but shuts off just as fast, creating continuous short cycles. This instability causes bothersome temperature fluctuations in the room.

  • Excessive humidity: A unit that’s too large never runs long enough to properly dehumidify the air. As a result, the air remains humid and uncomfortable, especially during Longueuil’s humid summers.

  • Premature wear on the equipment: The frequent start-stop cycles prematurely wear out internal components, increasing maintenance costs and reducing the air conditioner's lifespan.

A real-world case: an oversized Fujitsu Halcyon wall-mounted air conditioner in Longueuil

We were recently called to resolve a major issue in a condo located in the Saint-Hubert area of Longueuil. The homeowner had installed a 24,000 BTU Fujitsu Halcyon wall-mounted air conditioner in a space that required only 12,000 BTU. Within the first few weeks of use, the following problems emerged:

  • Constant temperature fluctuations, making the home uncomfortable;

  • Persistently high humidity, despite the rapid cooling;

  • Unusually high electricity bills due to excessive energy consumption caused by the frequent stops and starts of the unit.

Precise diagnosis and solutions provided by AirGreen

Our technical team quickly identified the root of the problem: the cooling capacity was twice as high as what the space required. The solution recommended by AirGreen was clear and effective:

  • Replacing the existing unit with a 12,000 BTU Fujitsu Halcyon wall-mounted air conditioner, properly sized for this living space;

  • Professional installation by our certified technicians, ensuring optimal and durable operation;

  • Immediate result: stable comfort, significant reduction in humidity, and a notable drop in monthly energy costs.
