St. Catharines, ON Heating & Cooling

Supply and install replacement HVAC unit. Remove and dispose of old unit. Modify duct work on roof to adapt to new unit. Electrical and gas connections included. Crane included.

Work Performed: Completed furnace maintenance, fireplace maintenance, and HRV maintenance. Cleaned fireplace components including glass. HRV maintenance completed—unit is clean and operating well. Controlled by an HRV controller near the thermostat, running independently (not wired to the furnace fan). Furnace Inspection Details: Furnace is a 25-year-old high-efficiency unit with internal rust damage from a previous or possibly active leak. Leak appears to be coming from the collector box and draft inducer motor. Performed safety inspection, including combustion test, heat rise, and limit checks—unit is currently operating within spec, but condition is concerning. Rust and corrosion present inside the cabinet indicate deterioration. Concerns & Recommendations: Existing black plastic venting does not meet current 636 standards. Signs of previous leakage at vent joints also noted. While repairs could include: Replacing the collector box, Replacing the inducer motor, and Updating the 2

Work Performed: Responded to gas leak concern after gas meter was replaced. Gas line red-tagged due to potential leak. Performed preliminary leak detection using bubbles—no visible leak found, but electronic gas sniffer detected presence of gas. Located a union on 1” gas line in a tight space with very limited access for tools. Leak may be located in a finished ceiling area—drywall may need to be cut to complete proper inspection and repair. Next Steps Required: Cap boiler, water heater, and stove lines. Pressurize main gas line to 15 psi to properly locate the source of the leak. Potential drywall removal required to expose concealed sections of piping. Additional Notes: Additional work will most likely be needed to complete repairs at additional costs. Boiler is a natural draft unit and requires annual maintenance and combustion (CO) testing for safety and proper operation.

2 April 2025 Replaced leaking air bleeder on top of navien boiler. Cleaned up light corrosion on nearby parts. No leaks present at this time after completion of work. Boiler is working well.

Work Performed: Performed full maintenance on the furnace, including: ✅ Temperature rise check – Found it on the higher end of normal, adjusted gas pressure accordingly. ✅ Combustion analysis & safety check – No immediate concerns, system is safe. ✅ Checked electrical components & blower motor – Verified proper operation. ✅ Flame sensor cleaned – Ensuring reliable ignition. I took out a piece of insulation that was loose inside the blower cabinet that is no longer needed as it was glued onto the side but it was about to be sucked into the blower motor so I removed that in the system is OK without it. Humidifier pad needed replacement, but the customer chose to leave it off for now as the system was not working and would have required further troubleshooting. System Condition & Recommendations: Furnace is a 16-year-old Goodman unit and is still operating fine. The blower motor is ECM (Electronically Commutated Motor), which is highly sensitive to airflow restrictions caused by dense

Evans Premier Furnace and Air Conditioner Installation

Furnace Maintenance: Added telfon tape to the collector box plug to avoid further condensation damage. Flushed the condensate lines to ensure proper drainage. Inspected pressure switch tubing for optimal functionality. Cleaned and polished the flame sensor to enhance performance. Performed diagnostic testing to verify efficient system operation. System operating well.

Work Performed: Addressed Enbridge red tag due to a gas leak on the main supply line. Enbridge replaced the gas meter and identified a leak near a fitting close to a union. Disassembled the union, tightened the fitting, and confirmed the leak was resolved. Performed a full gas leak test—no leaks present at this time. Noted serious safety concern with the upstairs gas stove, which has standing pilots and no safety shutoff if the pilot goes out. Gas was continuously leaking from the stove—advised replacement. Spoke with Dan and received approval to turn off gas supply to the stove for safety. Advised that the stove must be replaced and offered to install a new one if provided by the customer. A new gas hose will also be required. Turned on the water heater and furnace—both are operating properly. Results: House is leak-free, and all appliances are operational except for the gas stove, which has been shut off for safety. Red tag will be cleared by the office.

Lennox Furnace maintenance and inspection. Performed full maintenance on furnace Found heavier corrosion than normal on burners, got information required to run warranty on replacement burners. Other than that, furnace is in good shape at this time. It is working well and running efficiently. Found no other problems or concerns during visit.

Navien tankless water heater maintenance and inspection. Performed flush on the tankless with descaler solution. Inspected and cleaned internal water filter, air filter and condensation trap. Found moderate buildup of dust etc. on air filter, Large amount of calcium buildup on water filter, about half plugged, would have put a lot of strain on the system if it can only allow half the proper flow of water through itself. Highly recommend getting tankless serviced more frequently, it is recommended to do it at least every two years to avoid overworking or damaging the system. After completion of maintenance tankless is working well, no concerns at this time.
