If you’ve invested in an air source heat pump, you’ve already made a smart move. It’s one of the most efficient, year-round systems available for heating and cooling in Ontario. But what a lot of homeowners don’t realize is that even the most advanced systems need routine attention.
When you skip annual maintenance, you’re not just taking a break from service calls — you’re taking a gamble with your comfort, efficiency, and long-term system reliability.
Let’s break down what really happens when a heat pump is left unchecked, and why a little preventive care goes a long way in a city like Waterloo.
The Hidden Cost of “It’s Probably Fine”
It’s easy to forget about your heat pump when it’s quietly doing its job. But inside that outdoor unit, the system is constantly moving refrigerant, managing airflow, and adjusting to temperature shifts.
Over time, even a small issue like dust buildup, a loose fan belt, or a low refrigerant level can start draining performance. You might not notice it at first — just slightly higher bills or a longer time to reach your desired temperature.
But those small inefficiencies compound. A clogged filter or blocked coil means the system works harder to move air, stressing components and driving up your hydro usage. What would’ve been a quick service visit can turn into a full repair or early system replacement.
Skipping maintenance doesn’t save money. It just delays the bill until it’s much bigger.
Waterloo’s Weather Doesn’t Go Easy on Heat Pumps
Air source heat pumps are designed to handle our changing Ontario climate — from humid summers to freezing winters — but they can’t do it alone. In Waterloo, wide temperature swings put your system through constant changeovers between heating and cooling. That back-and-forth adds wear that only regular maintenance can balance out.
When the outdoor coil freezes up in winter or the system struggles with humidity in July, you’ll feel it in the house. Without a clean filter and tuned components, the system loses its ability to efficiently extract or release heat. The result: uneven comfort, poor airflow, and that frustrating “why is it running so long?” feeling.
Routine maintenance keeps everything in sync, so your home stays comfortable no matter how unpredictable the weather gets.
Maintenance Protects the Efficiency You Paid For
The main reason people choose an air source heat pump is efficiency. It can deliver three or more units of heating energy for every unit of electricity consumed — a huge step up from traditional furnaces or electric baseboards.
But that performance depends on clean airflow, correct refrigerant pressure, and accurate sensors. Dirt on coils or dust in filters can throw off that balance, forcing the system to work harder and reducing efficiency by as much as 20–25%.
A yearly service call includes coil cleaning, refrigerant checks, and airflow testing to keep those numbers where they should be. The result? Consistent performance, quieter operation, and real energy savings that show up on your monthly utility bill.
Extending the Life of Your Heat Pump
A well-maintained air source heat pump can last 15 years or more. But neglect shortens that lifespan fast. Worn bearings, dirty coils, or unbalanced fans put extra strain on the compressor — the heart of the system — and that’s one part you don’t want to replace early.
Regular maintenance is like an oil change for your car. It’s not exciting, but it keeps everything running smoothly and prevents breakdowns at the worst possible time.
For homeowners around Waterloo, Kitchener, and Cambridge, this isn’t just about saving money — it’s about ensuring reliable comfort during our toughest weather swings.
Warranty and Protection You Don’t Want to Lose
Most manufacturers require regular maintenance to keep your warranty valid. If you skip it, and a part fails, you might be footing the full repair bill — even if the unit is technically under warranty.
Having your system serviced by a qualified technician from Waterloo Energy Products not only protects that warranty but also provides a full service record. That kind of documentation matters for resale value, insurance, and peace of mind.

How Often Should You Schedule Maintenance?
At minimum, your air source heat pump should be serviced once per year — ideally before the heating or cooling season begins.
If your system runs nearly year-round, consider a spring and fall check-up. This ensures both heating and cooling functions are working at peak efficiency and gives technicians a chance to clean, test, and calibrate before seasonal demand hits.
It’s a small time investment that can prevent major headaches later.
Signs Your Heat Pump Needs Service Now
Even if it’s not time for your annual visit, a few warning signs mean it’s time to call in a pro:
-
You hear new noises or vibration from the outdoor unit.
-
Your system runs longer but doesn’t heat or cool effectively.
-
The air feels less consistent or more humid than usual.
-
Your energy bills have jumped without explanation.
Any of these can indicate airflow issues, refrigerant problems, or sensor faults — all of which are best handled early.
