Heat Pump Maintenance and Tune-Up in Greater Vancouver
Heat pumps work hard year-round — heating in winter and cooling in summer. Regular professional maintenance keeps your heat pump running at peak efficiency, reduces energy costs, prevents breakdowns, and extends the life of your equipment. Our licensed technicians service all major heat pump brands throughout Greater Vancouver.
Heat Pump Maintenance Overview
Regular heat pump maintenance is essential because these systems run year-round — heating in winter and cooling in summer. Unlike a furnace that operates only during cold months, a heat pump accumulates twice the runtime hours. Annual professional service maintains efficiency, reduces energy costs, extends equipment life, and preserves manufacturer warranty coverage. Our licensed technicians service all heat pump brands including Mitsubishi, Fujitsu, Daikin, Tosot, LG, Gree, and Climate Master.
Outdoor Unit Inspection and Cleaning
The outdoor unit (condenser) is exposed to weather, debris, and environmental wear. We inspect the outdoor coil for dirt, leaves, cottonwood, and other debris that restricts airflow. The coil is cleaned with a mild cleaning solution and rinsed to restore heat transfer efficiency. The outdoor fan motor, fan blade, and grille are inspected. The unit is checked for level installation and proper clearance from walls and landscaping.
Indoor Unit and Air Handler Service
The indoor air handler or ductless indoor unit is inspected for proper airflow, cleanliness, and operation. The indoor coil is checked for dirt or frost buildup. The condensate drain pan and drain line are inspected for blockages, algae growth, and proper drainage. For ductless systems, the indoor unit filters are cleaned or replaced. The blower motor and blower wheel are checked for dirt accumulation.
Refrigerant Charge Verification
A heat pump with an incorrect refrigerant charge cannot heat or cool efficiently. We measure the refrigerant subcooling and superheat to determine if the charge is correct. An undercharged system (low refrigerant) indicates a leak that must be located and repaired. An overcharged system reduces efficiency and can damage the compressor. Refrigerant handling requires EPA certification and is performed by licensed technicians.
Reversing Valve and Defrost Cycle Test
The reversing valve switches the heat pump between heating and cooling modes. We test the valve for proper operation in both modes. The defrost cycle is tested to ensure the outdoor coil defrosts correctly in cold weather. A failed reversing valve or defrost control can leave the heat pump stuck in cooling mode or frozen in winter.
Compressor and Electrical Component Check
The compressor is tested for proper amp draw, voltage at the terminals, and capacitor condition (start and run capacitors). Loose electrical connections can cause voltage drop, overheating, and component failure. All wiring connections at the contactor, capacitor, and control board are inspected and tightened. The contactor is checked for pitting or wear.
Thermostat and Control Testing
The thermostat and control system are tested for proper communication with the heat pump. We verify heating and cooling setpoints, staging, auxiliary heat operation, and defrost control. For smart or communicating thermostats, we ensure the system is properly configured for your specific heat pump type and indoor unit.
Air Filter Service
The air filter is inspected and replaced if dirty. For ductless systems, the washable filters in each indoor unit are cleaned. A dirty filter is the most common cause of reduced performance and increased energy consumption. We verify the correct filter size and MERV rating for your system.
Ductwork Inspection (Ducted Systems)
For ducted heat pump systems, we inspect accessible ductwork for air leaks, disconnected joints, and proper insulation. Duct leakage can waste 20 to 30% of conditioned air. We check supply and return registers for proper airflow and recommend sealing and insulation improvements where needed.
Safety Controls and Carbon Monoxide Testing
For heat pumps with gas-fired auxiliary heat (dual-fuel systems), we test the gas furnace backup for proper combustion, venting, and carbon monoxide production. All safety limit switches and pressure switches are tested. For electric auxiliary heat, we check the heating elements and safety limits for proper operation.
System Performance Report
After completing the inspection and tune-up, we provide a detailed written report of our findings including refrigerant pressures, temperature rise/cooling drop, amp draws, component conditions, and any recommendations for repairs or efficiency improvements. You receive a clear picture of your heat pump's condition and operating efficiency.
Safety Reminder
If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
