Maintaining your central heat pump: an investment in durability and performance
Central heat pump maintenance isn’t something to take lightly. At AirGreen, we’ve seen time and again that many breakdowns, performance drops, or spikes in energy use are directly linked to a lack of preventive maintenance. Yet, with a few simple actions and a clear understanding of what you can do yourself — and especially what should be left to a professional — you can extend your HVAC system’s lifespan, boost its efficiency, and avoid unexpected expenses.
Why should you regularly maintain your central heat pump?
A central heat pump, whether it’s from Goodman, Bosch, Fujitsu, Trane, Lennox, or Arcoaire, is a complex machine that constantly processes the air in your home. It deals with humidity, dust, temperature fluctuations, clogged filters, and sometimes even inadequate ventilation. All of this impacts its performance, energy efficiency, and ultimately, its lifespan.
Here are some benefits of proper maintenance:
-
Optimal performance: a clean unit runs at full capacity.
-
Energy savings: a well-maintained system consumes less energy.
-
Extended lifespan: a properly maintained heat pump can last 15 to 20 years.
-
Fewer unexpected repairs: early detection of technical issues.
What you can do yourself: simple but powerful actions
Clean or replace air filters
Air filters are your first line of defense against airborne particles. A dirty filter blocks airflow, forcing the system to work harder.
-
Recommended frequency: every 1 to 3 months.
-
AirGreen tip: in homes with pets or high foot traffic, check filters monthly.
Inspect vents and air registers
Make sure nothing is blocking the return grills or air supply vents. A couch in front of a vent can throw off airflow and create temperature imbalances.
Clean the outdoor grille (condenser unit)
Outdoor debris like leaves, snow, and dust can block the external unit.
-
Frequency: twice a year (spring and fall).
-
Caution: never use a high-pressure hose — it can damage the fins.
Check the thermostat
Make sure the thermostat is functioning properly and programmed according to your lifestyle. A bad setting can drive up your energy bill.
Watch for unusual noises
Whistling, clicking, or humming sounds are red flags. They could point to a fan issue, compressor problem, or belt wear.
When to call an AirGreen professional: know your limits
While many tasks are within reach for homeowners, some checks and repairs must be handled by trained HVAC professionals.
Full annual inspection
We recommend a professional preventive maintenance visit once a year, ideally in spring or fall, to:
-
Check refrigerant pressure (R-32, R-410A, R-454B, etc.)
-
Inspect electrical connections and electronic components
-
Evaluate motors, fans, and coils
-
Clean the evaporator and condenser coils
-
Ensure the system meets energy efficiency standards
Diagnosing performance loss
If your system isn’t heating or cooling like it used to, even though the thermostat is set correctly, it could be due to a refrigerant leak or a compressor nearing the end of its life. Time to call in the pros.
Persistent odors or mold
If there’s a strange smell when your central system kicks on, mold in the ductwork could be the cause. AirGreen offers full duct cleaning services, including antimicrobial treatment if needed.
Real examples of AirGreen service calls in Montréal and surrounding areas
Case #1 – Bosch IDS Premium R-454B central heat pump in Laval
A bungalow owner in Laval reached out after noticing a drop in performance from their Bosch central heat pump, just three years after installation. The system had never been serviced. After a full inspection, we found heavy buildup on the coils and low refrigerant pressure. With a proper cleaning and recharge, the system was back to full efficiency.
Case #2 – Preventive maintenance of a Goodman central system in Longueuil
Each year, a family in Longueuil entrusts us with the maintenance of their 48,000 BTU Goodman central heat pump. The result: zero breakdowns over 7 years, stable energy bills, and clean indoor air. This kind of annual maintenance prevents unwanted surprises.
Case #3 – Fujitsu KZAH R-32 unit in Montréal, Plateau-Mont-Royal
We recently installed a Fujitsu central heat pump in a Plateau triplex. Three months later, the client noticed some condensation forming in the ductwork. We stepped in quickly to add extra insulation around the supply duct and ensure proper ventilation. The issue was resolved in just half a day.
Practical tips to extend your system’s lifespan
-
Schedule preventive maintenance yearly, even if everything seems fine.
-
Keep your warranty documents and maintenance reports — they come in handy for resale or claims.
-
Install a smart thermostat to optimize energy usage.
-
Avoid DIY repairs or chemical cleaners — they often do more harm than good.
-
Work with a certified, HVAC-specialized company like AirGreen.
