Furnace Maintenance and Tune-Up in Greater Vancouver
We provide professional furnace maintenance and tune-up service throughout Greater Vancouver. Our licensed technicians perform a thorough multi-point inspection and safety check on your furnace. Using calibrated diagnostic equipment, we test for carbon monoxide, measure combustion efficiency, inspect the heat exchanger, clean the burner assembly, check all safety controls, and ensure your furnace is operating at peak performance and safety. After completing the service, you receive a comprehensive written report of our findings and recommendations.
Gas Supply and Safety Check
We inspect the gas supply line from the shutoff valve to the burner for leaks using electronic gas detectors. Gas manifold pressure is measured and adjusted to manufacturer specifications. All gas connections are checked and tightened. We verify the gas valve operates correctly through a complete heating cycle.
Burner Assembly Inspection and Cleaning
The burner assembly is inspected for corrosion, misalignment, and debris. Burners are cleaned to ensure proper flame pattern and combustion. We check the burner orifice for clogs that could affect gas flow. The burner compartment is inspected for any signs of delayed ignition or flame rollout.
Ignition System Service
The ignitor is tested for proper glow and resistance (hot surface ignitor) or spark quality (spark ignition). The flame sensor is cleaned with fine steel wool and its microamp signal is measured against the manufacturer specification. A weak flame signal can cause intermittent operation and lockouts.
Heat Exchanger Inspection
The heat exchanger is visually inspected for cracks, rust, and corrosion using a video inspection camera. On condensing furnaces, we check the secondary heat exchanger for blockages or corrosion. A cracked heat exchanger is a serious safety concern that can allow carbon monoxide into your home. We perform combustion analysis to verify complete combustion.
Ventilation and Combustion Air Check
The vent pipe (or chimney) is inspected for blockages, rust, corrosion, and proper slope. Combustion air openings are verified as unobstructed. For high-efficiency furnaces, we inspect the PVC intake and exhaust pipes for separations, sagging, and weather damage. Outdoor terminations are checked for snow, ice, leaves, or debris.
Condensate System Service
Condensate drain lines and traps are inspected for blockages, cleaned, and flushed. The condensate pump is tested for proper operation and the float switch is verified. On high-efficiency furnaces, we check the collector box, hoses, and secondary heat exchanger drain for obstructions.
Blower Motor and Airflow Check
The blower motor is inspected for bearing noise, proper RPM, and electrical connection integrity. The blower wheel is checked for dirt buildup that can unbalance it and cause vibration or bearing wear. For variable-speed and ECM blowers, we verify proper speed signals and amp draw against specifications.
Air Filter Service
The air filter is inspected and replaced if dirty. We verify the correct filter size and type (MERV rating) for your furnace. A dirty filter is the most common cause of reduced airflow, overheating, and limit switch issues. We can set up a filter replacement schedule for your specific filter type.
Safety Controls Testing
All safety controls are tested including the high-temperature limit switch, flame rollout switch, and pressure switch. We verify the limit switch opens at the correct temperature and resets properly. The pressure switch is tested for proper vacuum pressure and switch closure. Each safety device is verified to shut down the furnace when required.
Thermostat and Control Testing
The thermostat is tested for accurate temperature reading and proper communication with the furnace. We verify the heat call, fan call, and staging signals (for two-stage or modulating furnaces). Control board error codes and history are reviewed. The furnace is cycled through a complete heating sequence from call for heat through warm-up, heating, and shutdown.
Electrical Connection Check
All electrical connections are inspected for tightness, signs of overheating, or corrosion. The furnace disconnect switch is tested. Voltage is measured at the furnace and compared to the nameplate rating. Wiring for any signs of damage, rodent activity, or wear is inspected and addressed.
Temperature Rise Verification
We measure the temperature rise across the furnace — the difference between the return air temperature and the supply air temperature. This must be within the range specified on the furnace nameplate. An incorrect temperature rise can indicate airflow problems, an oversized or undersized furnace, or a gas pressure issue.
Carbon Monoxide Testing
Carbon monoxide levels are measured in the flue gas and in the air surrounding the furnace. We test using a calibrated combustion analyzer. Zero CO in the flue gas is the ideal reading. Any detectable CO requires investigation. We also verify your home has working CO detectors on every floor.
System Performance Report
After completing the inspection and tune-up, we provide a detailed written report of our findings. This includes component condition, measurements taken, any issues identified, recommendations for repairs or future service, and photos where helpful. You will have a clear picture of your furnace condition and any action items.
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.
