Understanding the secrets of professional central heat pump maintenance
Annual central heat pump maintenance is a step that’s often underestimated, yet it’s crucial for ensuring performance, longevity, and energy savings. At AirGreen, we understand that proper maintenance goes far beyond simply cleaning the filters. Our certified technicians inspect every component, assess the smallest warning signs, and optimize the system so it operates at full capacity — all year long. Whether you’re in Montréal, Laval, Longueuil, on the North Shore or the South Shore, professional maintenance can make all the difference between long-lasting comfort and unexpected costs.
Why should you maintain your central heat pump every year?
A central heat pump, whether it's from Fujitsu, Bosch, Lennox, Trane or Goodman, is a sophisticated system that combines heating and cooling. When neglected, dust, humidity, and mechanical vibrations can seriously affect its performance. The result? Higher electricity bills, frequent breakdowns, or worse, a system that fails prematurely.
Annual professional maintenance prevents these issues while maintaining optimal energy efficiency. Our clients often notice up to a 25% performance boost and a significant reduction in noise after our visit.
What AirGreen technicians inspect (and what you might be missing)
In-depth inspection of indoor components
-
Evaporator coil check: When dirty, this component can lose up to 15% of efficiency. We clean it carefully using specific biodegradable products.
-
Fan motor analysis: A poorly lubricated or unbalanced motor increases energy consumption and reduces airflow distribution.
-
Temperature probe inspection: If misaligned, it disrupts the heating/cooling cycles. We recalibrate it if necessary.
-
Condensate drain check: If clogged, it can cause internal water leaks and invisible mold. Our teams always clear and disinfect this section.
Outdoor inspection of the compressor and outdoor unit
-
Refrigerant pressure check (R-32, R-410A, R-454B depending on the brand): An imbalance reduces heating capacity in winter and cooling capacity in summer.
-
Condenser coil cleaning: Dirt and debris interfere with heat exchange. We use a low-pressure jet and a specialized brush.
-
Compressor test: This is the heart of the central heat pump. A high inrush current may indicate an imminent failure.
-
Casing stabilization: Excessive vibrations reduce the lifespan of electronic components. We tighten the anchors and adjust fastenings.
Real examples of maintenance performed by AirGreen
Maintenance project in Blainville – North Shore
A client had a Bosch BOVA 36,000 BTU central heat pump installed in a recently built home. Although the system appeared to work correctly, our technicians found early signs of condenser coil fouling, reducing cooling capacity. Thanks to targeted cleaning and a refrigerant top-up with R-454B, we restored efficiency to 100%, with an immediate 17% drop in energy consumption according to the client’s meter.
Service call in Longueuil – South Shore
In a single-family home equipped with a Goodman R-32 central heat pump, the client complained of cold drafts during winter. Our team identified a poorly sealed damper in the main duct — invisible to the untrained eye. In addition to fixing this issue, we readjusted the pressure of the refrigeration circuit. Thermal comfort was instantly restored.
What’s at risk if you skip annual maintenance?
-
Unexpected breakdowns in the middle of winter or during heatwaves
-
Voided warranty (most manufacturers require proof of yearly maintenance)
-
Consistently high energy consumption
-
Mold buildup in the ductwork
-
Decline in indoor air quality, especially for sensitive individuals
What you can do between professional visits
-
Clean filters every 30 days
-
Watch for unusual noises
-
Keep the outdoor unit clear of leaves or snow
-
Take note of any performance changes to mention to your technician
How often should you perform maintenance?
We recommend a full HVAC maintenance once per year, ideally in the fall or spring. This routine allows us to detect potential problems before they become critical.
