A Real-Life Experience in Longueuil That Highlights the Importance of Professional HVAC Installation
Installing a wall-mounted heat pump should bring both comfort and significant energy savings. However, even a small mistake can quickly turn this investment into a financial nightmare. At AirGreen, we witnessed firsthand such a misfortune experienced by a resident of Longueuil. Here is his story, and how our expert intervention quickly resolved this critical issue.
The Promise of an Efficient and Economical Wall-Mounted Heat Pump
When Mr. Girard (name changed for privacy), a Longueuil resident, had a wall-mounted heat pump installed three years ago, his primary objective was clear: significantly reduce his electricity bills while enhancing his home's thermal comfort. Convinced by the widely advertised advantages of wall-mounted heat pumps—energy efficiency, eligibility for grants, and ease of installation—he chose a local contractor to handle the installation.
The Unexpected Problem: Bills Tripled
Everything seemed normal during the first few weeks following his wall-mounted heat pump installation. However, as soon as winter arrived, Mr. Girard noticed a significant and troubling increase in his electricity bills. From a typical monthly bill of about $200, the amount suddenly rose to nearly $600 per month, an exorbitant cost for a standard-sized family home in Longueuil.
With the situation failing to improve over the months, Mr. Girard turned to our team of HVAC installation experts at AirGreen, renowned for our deep expertise in air conditioning and heating systems throughout Montreal, Laval, Longueuil, the North Shore, and the South Shore.
AirGreen’s Professional Intervention: Detailed Diagnosis and Rapid Solution
After a thorough diagnosis by our certified technicians, we quickly identified the root cause of the problem: a simple yet crucial mistake made during the initial installation.
During the original installation performed by a non-specialized contractor, technicians improperly calibrated the heat pump’s refrigerant charge. This error, seemingly minor to an untrained eye, directly caused the unit to continuously operate at maximum capacity, resulting in dramatically increased energy consumption.
Why Incorrect Refrigerant Charge Drastically Impacts Your Bills
A heat pump’s refrigerant charge is fundamental. Too little refrigerant, and the heat pump must constantly compensate, working tirelessly to achieve the set temperature. Too much refrigerant, and energy efficiency dramatically drops, unnecessarily increasing the unit’s start-stop cycles. In both scenarios, energy consumption skyrockets.
This is exactly what happened at Mr. Girard’s home in Longueuil. The wall-mounted heat pump, though modern and efficient, had become a financial drain simply due to this initial technical error.
AirGreen’s Correction: A Decisive Intervention
Our HVAC experts immediately corrected the refrigerant charge, strictly adhering to the manufacturer’s recommended technical specifications. For this particular installation in Longueuil, the unit was a Fujitsu ASUG18KLCA wall-mounted heat pump of 18,000 BTU, renowned for its exceptional efficiency (SEER 20.0 / HSPF 10.3) and eligible for Hydro-Québec’s LogisVert grant of up to $1,700.
The correction took only a few hours, including a rigorous system test. Immediately after our intervention, Mr. Girard noticed a dramatic improvement in the performance of his heat pump: quieter operation, less frequent cycling, and above all, significantly improved energy efficiency.
Returning to Normal: Savings and Comfort Restored
The result of our professional intervention was spectacular: from the very next month, Mr. Girard’s electricity bill returned to normal levels, immediately decreasing to about $175 per month during the winter. This intervention allowed him to finally enjoy the expected benefits of a modern wall-mounted heat pump, combining thermal comfort with substantial energy savings.
