Heat Pump MAINTENANCE Reviews

What Happens If You Don’t Maintain Your Heat Pump?

Skipping routine maintenance may seem like a small saving, but it usually costs more in the long run—both in energy efficiency and repair costs. Without proper care:

  • Efficiency drops. Dust, debris, and restricted airflow force your heat pump system to run longer cycles to reach the same temperature, significantly increasing electricity use and driving up your monthly bills.
  • Wear accelerates. Dirty coils and strained components cause overheating, premature compressor failure, and more frequent repairs.
  • Comfort declines. Neglected systems can’t maintain even temperatures, leaving you with cold spots in winter or inadequate cooling in summer.
  • Safety can be compromised. Loose electrical connections, blocked condensate drains, or refrigerant leaks can lead to short circuits, water damage, or equipment failure.

Routine HVAC service prevents these problems and keeps your system operating the way the manufacturer designed it.

Things We Check In Your Heat Pump

Professional heat pump maintenance goes far beyond replacing an air filter. Our certified HVAC technicians use advanced diagnostic tools to inspect, clean, and test every part of your system.

Comprehensive Heat Pump Maintenance Checklist

Refrigerant System Diagnostics
We connect digital gauges to measure pressures, temperatures, and calculate superheat/subcooling. These readings confirm the correct refrigerant charge and detect potential leaks.
Coil Inspection & Cleaning
Indoor coils (evaporator) and outdoor coils (condenser) are checked for dust and debris that block heat transfer. When needed, coils are gently cleaned to restore efficiency.
Airflow & Filter Maintenance
Technicians inspect the return and supply for proper airflow, verify duct integrity, and clean or replace filters to prevent restrictions and ensure ideal air quality.
Electrical Connections
All electrical connections, contactors, relays, and wiring are tightened and tested for proper voltage, amperage, and signs of overheating or corrosion.
Blower Motor & Fan Components
Motors and bearings are inspected and lubricated (if applicable). We verify that the blower wheel and outdoor fan are balanced and spinning freely.
Defrost & Reversing-Valve Operation
We test that the heat pump’s cooling system switches smoothly between heating mode and cooling mode, and that the defrost cycle starts and ends correctly.
Thermostat & Control Logic
We confirm thermostat calibration and verify that system startup, shutdown, and backup-heat sequencing operate safely.
Condensate Drain & Pan
The drain line and trap are flushed to prevent blockages that can cause leaks, water damage, or ice buildup.
Refrigerant Line Insulation
Damaged insulation is repaired to maintain heat pump efficiency and prevent condensation.
Performance Testing
We record the temperature difference between the return and supply air (“temperature split”) and compare it to the manufacturer’s specifications to verify proper refrigerant charge, proper air flow, and that the system is working to the manufacturer’s specifications.
Visual Inspection
Using an inspection light, we look for corrosion, moisture intrusion, oil stains (possible leaks), loose panels, and vibration issues.

Hybrid or Dual-Fuel Systems

For homes that combine a heat pump with a furnace backup, we also inspect the combustion components:

  • Measure flue gases with a combustion analyzer to verify safety, and clean, efficient burning.
  • Check the gas pressure at the valve for the correct supply.
  • Clean burners and heat exchangers, removing rust and debris for safe ignition.
  • Inspect venting and flue pipes for blockages or corrosion.
  • Test the switchover controls that determine when the furnace engages during extreme cold.

By customizing maintenance for your specific equipment, we ensure both sides of a hybrid system work together efficiently and safely.

Check Out Our Maintenance Plans

Our maintenance plans take the guesswork out of heat pump maintenance. Members of the VIP Protection Plan receive:

  • Comprehensive annual tune-up with inspection, cleaning, and lubrication
  • Priority emergency service—often same-day response, frequently within hours
  • One waived service call fee per year on covered equipment
  • Discounted repairs on parts and labour
  • Extended 3-year warranty coverage on repairs

Considering the cost of a single after-hours repair, a maintenance plan quickly pays for itself — and keeps your system running smoothly all year long.

With annual inspections, we can also report concerns and make corrections before components or parts fail. With so many new pieces of equipment available today, we simply can’t stock ALL parts to keep every system operating all year long.

Frequently asked Questions

Do you offer heat pump repair services?

Yes, we do and if you’re part of our maintenance plan, you can expect same-day service, frequently within just a few hours. Non-members are scheduled as soon as possible, which may be the same day or in a few days.

Are there government rebates for cold climate heat pumps?

Yes, rebates and government incentives are often available! Contact us or check our HVAC promotions page for the latest information.

What are the benefits of regular heat pump maintenance?
  • Lower operating costs through improved efficiency
  • Fewer emergency breakdowns and extended system life
  • Better comfort with steady, consistent heating and cooling
  • Peace of mind knowing your equipment is inspected by professionals familiar with Eastern Ontario’s demanding climate
Can cold climate heat pumps cool my home in summer?

Yes, cold climate heat pumps are reversible and can heat and cool your home, making them a year-round comfort solution.

You may want to learn about the difference between geothermal vs. cold climate heat pumps if you’re looking for one that also heats during cold Ontario winters.

Do heat pumps need regular maintenance?

Heat pumps operate year-round for heating and cooling. Therefore, regular maintenance is essential, including regular filter changes and tune ups to maintain efficiency and extend the system’s lifespan.

How often should I maintain my heat pump?

Most heat pumps should be professionally serviced at least once a year, but systems used year-round for both heating and cooling perform best with two tune-ups per year:

We recommend scheduling your heat pump maintenance during our off-peak periods to take advantage of reduced rates and ensure faster service during true emergencies. As long as you’re maintaining your air filters regularly, your system will perform well whether it’s serviced in peak season or during quieter months. 

Many customers schedule cooling maintenance in mid-to-late summer and heating service in early-to-mid winter to avoid the spring and fall rush, while receiving the same comprehensive care at a better price.

Between visits, homeowners can help by:

Listening for unusual noises or changes in performance and calling for service early

Checking or replacing filters every 1–3 months

Keeping outdoor units clear of leaves, snow, and debris
