The Hidden Trap of an Inadequate Central Air Conditioning System
In Montreal, Laval, Longueuil, and both the North Shore and South Shore, investing in a central air conditioning system is a major decision. However, according to our observations at AirGreen, nearly 60% of homeowners regret their choice after only five years. Why does such a high percentage of homeowners experience this costly regret? Often, the issue stems from a lack of precise information, poor equipment selection, or an inadequate HVAC installation. Here’s how to avoid these common mistakes based on real-life experiences from our fieldwork.
The Number One Mistake: Incorrect Sizing of the Central Unit
One of the most frequent regrets homeowners have is due to choosing an incorrectly sized central air conditioner. An oversized system will cycle on and off too frequently, increasing energy consumption and significantly reducing comfort. Conversely, an undersized unit will run constantly without achieving an optimal temperature, causing premature wear and significantly higher energy costs.
At AirGreen, we recently replaced an undersized central air conditioner for a home in Longueuil. The homeowner had originally chosen a 24,000 BTU unit when they actually needed at least 36,000 BTU to ensure optimal comfort. We proceeded with the installation of a new Goodman GSXC18 3-ton (36,000 BTU) unit, Energy Star-certified, and eligible for LogisVert subsidies. The result: a perfectly stable indoor temperature and an immediate 30% reduction in the annual energy bill.
HVAC Installation: A Crucial Detail Often Overlooked
Another major factor leading to regret is related to the initial installation. An incorrect HVAC installation can cut the efficiency of a new system in half, leading to significant additional costs in repairs and energy.
In Laval, we were recently called to a residence where the previous installation had been rushed. The air ducts were poorly sealed, causing significant air loss and rising energy costs. After restoring proper duct sealing and repositioning the ducts correctly, our technicians enabled the client to save about 25% annually on their energy expenses.
Central Air Conditioning: The Critical Importance of Energy Certifications
Neglecting energy certifications is another costly and common mistake. Many homeowners overlook the importance of certifications such as Energy Star or the qualifications required to benefit from Hydro-Québec's subsidy programs.
In a recent project in Montreal, a client had purchased a central air conditioning system without checking for these essential certifications. As a result, they were unable to benefit from the LogisVert program, which would have represented significant initial savings. We ultimately replaced their unit with a Bosch IDS Premium 4-ton heat pump, Energy Star-certified, and eligible for LogisVert, allowing the client to fully benefit from subsidies and maximum energy efficiency.
Neglected Maintenance: A Regret That Could Have Been Avoided
Homeowners often forget that even the best central systems require regular HVAC maintenance to maintain optimal efficiency. Neglecting this maintenance leads to costly breakdowns and dramatic performance declines.
On the South Shore, in Brossard, a condominium called us after noticing a significant drop in the performance of their central air conditioning system. Our team discovered clogged filters, a dusty heat exchanger, and ducts saturated with dirt. After a complete cleaning and thorough check-up, the condominium regained a fully functional system and saw their energy costs drop by 20% within the first month following our intervention.
