Shocking Testimonials: Why These Homeowners Regret Their Initial HVAC Indoor Unit Choice in Longueuil

When a Poor Indoor HVAC Unit Choice in Longueuil Leads to Serious Consequences

At AirGreen, we regularly meet clients who, after choosing a ceiling cassette, floor console, ducted, or ceiling-floor indoor unit from another provider, end up disappointed or frustrated by the results. Uneven comfort, poor energy performance, excessive noise, or poor architectural integration—the testimonials we’ve gathered in Longueuil remind us how crucial it is to have professional guidance from the start.

Today, we’re sharing several real-life cases from Longueuil—actual experiences where homeowners regretted their initial decision. More importantly, we explain how we fixed the situation thanks to our expertise in custom HVAC installation.

Case 1: A Ceiling Cassette That Didn’t Fit a Condo in Vieux-Longueuil

A couple who had recently moved into a renovated condo in Vieux-Longueuil had chosen a 4-way ceiling cassette unit from a competing brand, thinking it would offer both performance and discretion. However, the configuration of the drop ceilings didn’t allow for optimal airflow. The result:

  • Cold spots in the bedrooms

  • Overheating in the living room

  • Rising electricity bills

When these homeowners reached out to us, our team conducted a full thermodynamic analysis and proposed replacing it with a GREE FLEXI R32 ducted unit (24,000 BTU) paired with a multi-outlet air distribution system. In less than two days, the system was replaced, fully integrated into the drop ceiling, with balanced ventilation throughout every room. Comfort improved dramatically, and the homeowners immediately saw a drop in energy usage.

Case 2: A Noisy Ceiling-Floor Unit in a Saint-Hubert Shop

In a small shop located on Cousineau Boulevard in Saint-Hubert, the owner had installed a 36,000 BTU ceiling-floor unit to cool the retail space. While the system met the power needs, the noise from the indoor unit affected the customer experience. The installation had been done without considering the room’s acoustics or occupancy hours.

Our solution was to install two FUJITSU KZAH R32 dual-fan wall consoles (18,000 BTU each) placed at opposite ends of the space, offering:

  • Optimized quiet operation (20 dB)

  • More even air distribution

  • Eligibility for a $2,148 LogisVert Hydro-Québec grant

Since then, customers stay longer in the store, and the owner enjoys a comfortably climate-controlled commercial space.

Case 3: An Oversized Console in a Heritage Home in Fatima

A family living in a century-old house in Longueuil had installed an oversized floor console (30,000 BTU) thinking that higher capacity would guarantee comfort. Unfortunately, the unit triggered very short cycles, resulting in:

  • Premature wear of the compressor

  • Discomfort due to abrupt temperature changes

  • Poor humidity control

AirGreen’s technicians recommended a HAXXAIR DC-Inverter 15,000 BTU wall-mounted heat pump, better suited to the actual room volumes and the unique insulation features of the home. A discreet installation with custom-painted PVC trunking helped preserve the historical charm of the property. The result? A more comfortable home, reduced maintenance costs, and increased real estate value.

What These Testimonials Reveal: The Importance of a Tailored Diagnosis

These cases are not isolated. Too often, decisions are based on sales brochures or one-size-fits-all advice. But every building in Longueuil—whether residential, commercial, or heritage—has its own architectural constraints, insulation levels, air volumes, and usage profiles.

At AirGreen, our approach is based on a comprehensive on-site technical analysis, including:

  • Assessment of heat loss

  • Airflow simulations

  • Compatibility check with existing structures

  • Guidance to maximize available financial grants (up to $5,000 depending on model and installation type)

The Most Common Mistakes to Avoid

Here are some mistakes we frequently encounter during our interventions in Longueuil:

  1. Choosing an oversized unit: This increases installation costs and reduces energy efficiency.

  2. Ignoring indoor unit noise levels: Especially important in workspaces or bedrooms.

  3. Installing a unit without airflow studies: Leading to uneven temperature distribution.

  4. Overlooking ceiling height: A floor unit may block furniture, while a poorly placed cassette may create unpleasant drafts.

  5. Missing out on grant eligibility criteria: Some models or setups aren’t eligible for financial assistance.
