Prairie Diagnostics, Repair & Replacement Planning.
Deliberate mechanical evaluation built for extreme sub-zero Manitoba conditions. We replace guesswork and rule-of-thumb swaps with reference physical diagnostics, rigorous airflow baselines, and illustrative heat-loss calculations.
The 3-Step Diagnostic Protocol
A furnace stoppage in prairie deep freeze is rarely isolated. Every service dispatch follows an uncompromised tri-fold sequence prior to component replacement or condemnations.
Combustion Analysis & Flue Gas Scrutiny
Digital insertion probe testing measuring CO PPM, O2 percentage, stack temperature, and draft pressure under continuous high-fire operation. Verifies true air-fuel stoichiometry, preventing invisible heat exchanger poisoning.
Airflow & Total External Static Pressure Scan
Dual-port digital differential manometer profiling across the supply plenum and return drop. High static choking causes premature secondary heat exchanger failure, cracked primary clamshells, and high-limit lockouts.
Fibreoptic Articulating Heat Exchanger Probe
Full interior visual audit using an articulating high-resolution borescope through limit switch ports and blower assemblies. We inspect critical eyelets, curved bends, and secondary drainage fins without blind condemnation.
Draft motor resistance, gas valve static inlet pressure, condensate trap clarity check.
Silicon nitride microamp verification, flame rollout sensors, vacuum switch trip point.
Combustion gas calibration at 15-min peak fire; temperature rise across heat exchanger.
Printout of flue gas efficiency, static pressure map, written photographic audit.
Four Core Heating Service Pillars
Engineered solutions structured specifically around cold-weather survival, high operational efficiency, and prolonged equipment resilience in Manitoba homes.
Diagnostic Triage & Targeted Component Repair
When temperatures plummet below -30°C, system shutdowns are emergencies. Our technicians carry deep inventory directly on service vans to remediate the most common prairie failure points on the spot.
- Silicon Nitride Surface Igniters
- Dual-stage OEM Pressure Switches
- Sealed Ball-Bearing Draft Inducers
- Polished Flame Rectification Rods
- Universal ECM Blower Modules
- High-Limit Bi-Metal Safety Switches
Planned System Transitions & Commissioning
Moving from an aging, cracking mid-efficiency furnace to a precision modulating unit or dual-fuel hybrid system requires surgical planning. Every install receives engineered flue venting, intake isolation, and verified gas pressure setup.
- 96-98% Two-Stage Variable Speed
- Fully Modulating Gas Valve Furnaces
- Cold-Climate Air Source Heat Pumps (-30°C)
- Dual-Fuel Automatic Switchover Logic
- Custom Hand-Fabricated Supply Plenums
- System 636 reference topic PVC/CPVC Venting
Prairie Pre-Winter Maintenance & Freeze Protection
Standard filter changes do not prevent a Manitoba deep freeze shutdown. Our 26-point seasonal safety audit targets condensate drain line freeze points, secondary exchanger acidification, and exterior vent hoarfrost clearances.
- Condensate Trap Flushing & Neutralizer
- Exterior Vent Termination Clearance Verification
- Flame Signal Current Microamp Measurement
- Gas Manifold Pressure Tuning
- Blower Wheel Debris Removal & Balance
- Thermostat Heat Anticipator Calibration
Airflow & Ductwork Balancing
Uneven two-storey temperatures, freezing basements, or high-static whistling vents are symptoms of uncommissioned duct distribution. We measure CFM branch by branch and install manual damper solutions.
- Static Pressure Drop Alleviation
- Return Air Boot Undersizing Expansion
- Second-Floor Register Flow Calibration
- Manual Volume Damper Retrofitting
- Plenum Transition Turbulence Reductions
- ECM Constant CFM Profile Tuning
reference Verification, Not Guesswork Quotations
In extreme prairie climates, sizing heating equipment based on an automated web formula or square footage thumb-rule is gross negligence. An oversized furnace short-cycles, stresses heat exchangers, and freezes secondary ports; an undersized furnace fails precisely during a sustained -38°C polar vortex.
Ironvale requires an in-person building envelope inspection prior to any furnace replacement proposal. We audit ceiling R-values, window glass assemblies, foundation wall insulation, and blower door infiltration rates before specifying BTU inputs.
Electronic Combustion Analysis
Measures dynamic fuel combustion, stack temperature differential, and excess air dilution with chemical electrochemical sensors reference to Canadian natural gas profiles.
reference Differential Pressure
Profiles total static resistance across the blower wheel, evaporator coil, and return duct transition. Pinpoints hidden duct choking that burns out high-efficiency ECM motors.
Non-Destructive Optical Scope
Permits 360-degree high-definition imaging of hidden secondary condensing coils and primary curved heat exchangers. Eliminates erroneous guesswork on crack condemnations.
Common Sub-Zero Heating Failure Modes
At temperatures below -25°C, moisture condensation, exhaust draft velocity, and metal contraction create unique failure patterns specific to Manitoba homes.
