St. Catharines, ON Heating & Cooling

Work Performed: Inspected possible noise source from boiler venting on the outside of the house. Used a ladder to check the vent and inspect the noise. Identified that the noise was not from the property but from the neighbor's attic exhaust fan, which was making a squealing noise when the wind blows. Spoke with the client regarding their gas installation and fireplace system. Advised on maintenance for the fireplace, furnace, and air conditioning, which the client declined as they are selling the house. Results: The noise is confirmed to be coming from the neighbor’s property, not the client’s boiler or venting. No issues or noises detected from the furnace or boiler. Additional Notes: Maintenance for the fireplace and HVAC systems was discussed but not pursued at this time.

Navien boiler maintenance and inspection. Boiler is working well at this time. Found corrosion at top of boiler at bleeder snd air vent adapter. Air vent adapter should be swapped out due to corrosion on it. Found no other problems or concerns during visit

Installed hot water tank

3 March 2025 - Replaced faulty gas valve, performed full set up on valve. Performed full maintenance on furnace after completing repair. Furnace maintenance was needed as some components were quite dirty prior to cleaning. After completion of work, furnace is operating well. System is running efficiently with no other issues or causes for concern at this time

Findings: * On arrival, found the gas valve not opening during the ignition sequence. * Verified proper 24V signal being sent to the gas valve, confirming the gas valve is failing intermittently. * Was able to temporarily get the gas valve to operate, restoring heat to the home, but replacement of the gas valve is required to ensure reliable operation. Recommendations: * Gas valve replacement required as soon as possible. * Recommend performing a full furnace maintenance at the time of repair to inspect safeties, combustion, and overall system performance. Estimate will be provided for gas valve replacement and furnace maintenance.

Reason for Call: No heat – Goodman High-Efficiency Furnace Findings: On arrival, furnace showing pressure switch stuck open error code. Tested both pressure and found they are operating normally. Traced issue back to the circuit board — appears to have the sequence of operations confused and is not sending proper voltage to components. While troubleshooting, tapped on the board and confirmed there is a short in the circuit board — the board began smoking and a small arc was visible, confirming the board is faulty and unsafe to operate. Furnace has not had recent maintenance — unable to perform safety or efficiency checks as the furnace is not operational. Recommendations: Replacement of circuit board is required to restore heat to the property. Once repaired, a full furnace maintenance and inspection is absolutely necessary to verify the safe and efficient operation of the furnace. Tenants have no heat at this time — estimate will be provided in the morning.

Daikin furnace maintenance and inspection. Furnace is in good condition and working well at this time. Performed full maintenance, found no problems or concerns. Highly recommend calling in the spring when the weather starts to warm up for an AC maintenance as its been a while since it was done last.

Responded to no-heat call and found a high-efficiency Nordyne furnace (installed approx. 2014). Furnace displaying a pressure switch error code. Tested all pressure switches using a manometer and voltage meter—verified all switches and safeties are closing properly. Checked venting—confirmed it is clear. Draft inducer motor operating correctly. Found a loose wire on the last pressure switch in the series, preventing voltage from returning to the circuit board. Re-secured the wire. Performed full furnace maintenance, including: Cleaning and inspecting components Checking all switches and electrical connections Clearing drain lines Measuring temperature rise Performing combustion analysis to ensure safe and efficient operation. Furnace was operating normally, but client later reported it shut off again with the same pressure switch error code. Possible intermittent failure of the pressure switches. Tested pressures with a manometer, and readings were within range, but the issue may still

Performed full maintenance on Carrier high-efficiency furnace. Checked all electrical components, burners, inducer motor, venting, and safety controls. Verified gas pressure and adjusted to 1.7" WC on low fire and 3.7" WC on high fire per manufacturer specs. Measured temperature rise: 40°F on low fire, 50°F on high fire. Performed combustion analysis and verified safeties. Noticed humidifier using excess water; lowered water pressure. Inspected humidifier pad—found it severely decayed and likely to leak. Turned off humidifier. Client advised to replace humidifier pad (not stocked on truck). We can order and install or leave humidifier off. Air intake positioned over gas valve with no drainage—may cause condensation to drip on gas valve, leading to failure. Recommend relocating intake to side of furnace. Observed storage boxes around furnace and water heater; advised keeping boxes at least a couple of feet away from the water heater for safety. Noticed a plastic jug placed on top of the

Completed full system inspection and maintenance. Verified proper operation of thermostat, burners, inducer motor, and safety controls. Checked electrical connections, airflow, and venting. Measured temperature rise at 50°F. Performed combustion analysis and verified safeties. Checked and cleaned ignition assembly No issues found; System is operating within normal parameters.
