The vast majority of ductless heat pump breakdowns are not sudden — they build gradually from issues that could have been caught and corrected months earlier. Dirty coils reduce heat transfer efficiency by up to 30%. Low refrigerant caused by a slow leak stresses the compressor over time before it finally fails. A partially blocked condensate drain creates conditions for mould growth and water damage. Worn electrical contacts cause intermittent faults that eventually become permanent ones.

A trained technician can identify every one of these developing issues during a routine annual visit — and address them before they become emergency repair calls. The cost of a maintenance visit is a fraction of what most repairs cost, and it's a small fraction of what a premature compressor or control board replacement costs.

Beyond preventing breakdowns, regular maintenance also preserves the efficiency your system was designed to deliver. A heat pump that hasn't been serviced in several years may be consuming 20 to 30% more electricity than it should to maintain the same comfort levels — a cost you're paying every month without realizing it.

Our annual maintenance visits are thorough, systematic, and performed by certified technicians who know ductless systems inside and out. Every visit covers:

Indoor Unit Service

• Filter inspection and cleaning: We remove, inspect, and clean all washable filters. Clogged filters are the single most common cause of reduced airflow, icing, and system inefficiency.
• Evaporator coil inspection and cleaning: The indoor coil collects dust, allergens, and biofilm over time. We inspect the coil surface and clean it as needed to restore full heat transfer efficiency.
• Condensate drain inspection and flush: We inspect the drain pan and condensate line for blockages, mould, or damage, and flush the line to ensure proper drainage. A blocked drain is one of the leading causes of water damage from ductless systems.
• Blower wheel and fan inspection: We inspect the indoor blower wheel for dust accumulation and wear, and check that the fan operates smoothly and quietly.
• Air vane and louver check: We confirm that the directional vanes and auto-sweep louvers are functioning correctly for proper air distribution throughout the room.
• Electrical connection inspection: We check all electrical connections, terminal blocks, and wiring within the indoor unit for signs of corrosion, looseness, or heat damage.
• Control board and sensor test: We test the indoor unit's control board and temperature sensors to confirm accurate readings and proper communication with the outdoor unit.

Outdoor Unit Service

• Condenser coil inspection and cleaning: The outdoor coil is exposed to dirt, pollen, cottonwood, and debris year-round. We inspect and clean the coil fins to restore proper airflow and heat exchange capacity.
• Outdoor fan motor and blade inspection: We check the fan motor for bearing wear, unusual noise, and correct operating speed, and inspect fan blades for damage or imbalance.
• Compressor inspection: We listen for unusual operating sounds, check amperage draw, and assess overall compressor health — the most important and most expensive component in the system.
• Refrigerant level check: We check system operating pressures to confirm that refrigerant charge is within manufacturer specifications. Low refrigerant indicates a leak that needs to be located and repaired.
• Electrical component inspection: We inspect capacitors, contactors, fuses, and all electrical connections within the outdoor unit for wear, corrosion, or signs of impending failure.
• Defrost system test: We verify that the automatic defrost cycle is functioning correctly — essential for reliable heating performance during Ontario winters.
• Unit mounting and clearance check: We confirm the outdoor unit is securely mounted, level, and has adequate clearance on all sides for proper airflow.

Full System Performance Test

• Heating and cooling mode operation test: We run the system through both heating and cooling cycles and confirm it reaches set temperatures within expected timeframes.
• Temperature differential measurement: We measure the temperature difference between the air entering and leaving the indoor unit to confirm the system is delivering its rated capacity.
• Remote control and smart thermostat verification: We confirm all control functions — including scheduling, mode switching, fan speed, and smart home integration — are operating correctly.
• Overall system efficiency assessment: Based on the full inspection, we provide a written summary of the system's condition, any issues found, recommended actions, and the expected performance outlook.

Extended System Lifespan

A well-maintained ductless heat pump lasts 15 to 20 years or more. Systems that go without regular service often fail in 8 to 12 years — sometimes sooner when a preventable issue causes cascading damage to major components. The investment in annual maintenance routinely extends system life by years, deferring the cost of replacement well into the future.

Lower Energy Bills Year-Round

Dirty coils, low refrigerant, and restricted airflow all force your system to work harder to deliver the same comfort — consuming more electricity in the process. Regular maintenance keeps your system operating at or near its rated efficiency, which translates directly into lower hydro bills every month. For many Ontario homeowners, the energy savings from a properly maintained system pay for the maintenance plan on their own.

Priority Emergency Service

Maintenance plan members receive priority scheduling for emergency service calls. If your system breaks down during a January cold snap — when demand for HVAC technicians is at its highest — you go to the front of the line. In a province where winter temperatures can reach -20°C or colder, that priority matters.

Discounts on Parts and Repairs

If a repair is needed, maintenance plan members receive preferred pricing on parts and labour. We're already familiar with your system from our annual visits, which also means faster diagnosis and fewer return trips.

Warranty Protection

Most ductless heat pump manufacturers require evidence of regular professional maintenance to honour extended warranty claims. Our maintenance visits are documented and can be provided as proof of service if a warranty claim ever needs to be filed. Skipping annual maintenance doesn't just risk your equipment — it can also risk your coverage.

Peace of Mind

There's a straightforward peace of mind that comes from knowing a certified technician has inspected your system before every heating season and every cooling season. You're not left wondering whether that occasional noise or slight drop in performance is something to worry about. You know, because a professional has looked at it.

Professional annual servicing is essential, but there are a few simple things you can do yourself between visits to keep your system in top shape:

• Clean indoor filters monthly during peak seasons: Most ductless systems have washable filters that slide out without tools. Rinsing them under warm water and allowing them to dry fully before reinserting takes about five minutes and makes a meaningful difference in airflow and air quality.
• Keep the area around the outdoor unit clear: Remove leaves, grass clippings, cottonwood, and snow from around the outdoor unit. Maintain at least 18 to 24 inches of clearance on all sides. In winter, check periodically that heavy snowfall hasn't buried the unit.
• Don't block indoor air vanes: Make sure furniture, curtains, shelving, or other objects aren't positioned directly in front of the indoor unit. Blocked airflow causes the system to work harder and can lead to icing.
• Listen for changes: You know what your system sounds like when it's running normally. New noises — rattling, squealing, hissing, or repetitive clicking — are worth noting and reporting at your next service visit or sooner if they seem serious.
• Keep a record of error codes: If your system displays an error code or unusual indicator light pattern, note what it shows before resetting the unit. This information helps our technicians diagnose intermittent issues that may not be present at the time of the service visit.

For most Ontario homes, an annual professional maintenance visit is the standard recommendation and the minimum we advise. Many HVAC manufacturers specify annual servicing as a condition of their warranty coverage.

For systems running in particularly demanding conditions, more frequent servicing may be beneficial:

• Twice-yearly servicing: Recommended for systems in homes with pets (pet hair accelerates filter and coil clogging), homes in areas with high pollen or cottonwood seasons, or systems serving commercial or high-occupancy spaces.
• Pre-season servicing: Some homeowners prefer to schedule a visit just before the heating season begins in autumn and again before the cooling season starts in spring, ensuring the system is in peak condition for each period of heavy use.

How much does a maintenance plan cost?

Maintenance plan pricing depends on the number of systems in your home and the level of coverage selected. Contact us for a quote — we'll walk you through the options and help you choose the plan that makes the most sense for your equipment and budget.

Can I just book a one-time tune-up instead of a plan?

Yes. We offer one-time annual tune-up visits for homeowners who prefer to book year by year. A maintenance plan simply provides added value through priority service, parts discounts, and the convenience of scheduled reminders — but a single visit is always an option.

Does my manufacturer warranty require professional maintenance?

Most major ductless heat pump manufacturers — including Lennox, Daikin, Bosch, GREE, and American Standard — specify annual professional servicing as a condition of their extended warranty coverage. Failure to maintain service records can result in a warranty claim being denied. Our visits are documented and we can provide service records on request.

When is the best time of year to schedule a maintenance visit?

Late summer or early autumn — before the heating season begins — is the most popular time, as it ensures your system is ready for winter's heaviest workload. Spring is also a common choice to prepare for the cooling season. The most important thing is that it gets done consistently every year, regardless of timing.

What if my system needs a repair during the maintenance visit?

If our technician identifies a repair need during a maintenance visit, we'll explain the issue, provide upfront pricing, and proceed with your approval. Maintenance plan members receive preferred pricing on parts and labour. We carry a comprehensive inventory of common parts for all major brands and can often complete straightforward repairs on the same visit.

I just had my system installed. Do I need a maintenance plan right away?

New systems are covered by manufacturer warranties and typically don't require significant maintenance in their first year. That said, enrolling in a maintenance plan from the start establishes a consistent service record, ensures your first annual visit happens on schedule, and sets up your warranty documentation correctly. Many customers who purchase through Constant Home Comfort enrol in a plan at the time of installation.

Don't wait for a breakdown to remind you that your heat pump needs attention. A Constant Home Comfort maintenance plan gives you professional annual servicing, priority emergency response, discounted repairs, and the confidence that your system is in expert hands — all for a fraction of the cost of a single emergency repair call.
