When installing an HVAC system in your home, it's crucial to follow expert advice. This particular client, based in Laval, decided to ignore our recommendations on the installation of his central heat pump. Eight months later, he contacted us to redo much of the work, leading to additional costs and a loss of comfort at home. Here’s what happened.
The Choice of System and Initial Installation: An Imbalance from the Start
The client, who had recently renovated his home, chose to install a Fujitsu KZAH R-32 central heat pump with 24,000 BTU capacity. His goal was to improve thermal comfort while reducing energy consumption.
-
Model: Fujitsu KZAH R-32
-
Capacity: 24,000 BTU
-
Energy Efficiency: SEER of 19, HSPF of 10.5
-
Location: Laval
-
Grant Eligibility: LogisVert eligibility for a $1,800 grant
Our technicians provided a detailed installation plan: a specific location for the outdoor unit, ductwork placement indoors, and connection to a compatible smart thermostat. However, the client insisted on installing the system himself, only following part of our advice.
The first point of friction occurred when he chose the wrong spot for the outdoor unit. He placed it too close to the garage entrance without considering the airflow space needed.
Installation Errors: Performance Loss from the First Few Months
After a few months, several problems appeared:
-
Uneven temperature: some rooms were too cold, others too warm. The poor airflow caused by the poorly chosen location of the outdoor unit was the main issue.
-
Excessive noise: the outdoor unit was making constant noise, disturbing the residents, mainly due to insufficient space around the unit.
-
High energy consumption: despite the expected savings, the electricity bill was much higher than anticipated, mainly due to inefficient duct installation.
After 8 months of use, the client reached out to AirGreen to assess the situation. During the inspection, we quickly identified that the outdoor unit was poorly installed, and the ducts inside had not been properly insulated.
Re-adjusting the Installation: Returning to Basics with AirGreen
Once the inspection was complete, we took charge of the full system re-adjustment. Here are the steps we followed:
-
Relocated the outdoor unit: we moved it to the back of the house, away from the elements, with enough space for proper airflow.
-
Repaired the ducts: we insulated the ducts that had not been correctly installed, using appropriate materials to minimize energy loss.
-
Recalibrated the thermostat: we adjusted the thermostat to ensure optimal temperature regulation and efficient energy use.
After these adjustments, the client immediately noticed an improvement in comfort and a significant reduction in energy consumption, just as initially expected.
Mistakes to Avoid When Installing a Central Heat Pump
Our experience with this client highlighted several common mistakes homeowners make when installing HVAC systems themselves, including:
-
Improper placement of the outdoor unit: it is crucial to choose a clear, open space, away from heat sources or obstructions that can block the airflow.
-
Undersized ducts: ducts must be correctly sized and insulated to avoid energy losses and ensure even temperature distribution.
-
Excessive noise: the outdoor unit must be placed on a stable base and sufficiently distanced from sensitive areas.
-
Non-compliant installation: every HVAC system must adhere to electrical safety standards and air quality regulations. A non-compliant installation can compromise both safety and system performance.
At AirGreen, we are committed to providing a professional, efficient installation for every client to ensure not only system performance but also long-term comfort.
What You Need to Know Before Installing a Central Heat Pump in Your Home
If you’re thinking of installing a central heat pump, here are some key points to consider to avoid similar mistakes:
-
Call on experts: professional installation guarantees compliance with standards and system efficiency. Don’t take unnecessary risks.
-
Choose the right model for your home: select a model with the appropriate BTU capacity, and make sure it’s eligible for government grants like LogisVert or Rénoclimat.
-
Prepare your space: both the outdoor unit placement and the ducts should be planned from the start to ensure optimal airflow.
-
Ensure regular maintenance: to prolong your system’s lifespan, annual maintenance is essential. This includes cleaning filters, checking refrigerant levels, and testing performance.
