- Standard Diagnostic & Repair (Mon–Fri, business hours): From $149/hour + HST
- Scheduled After-Hours Diagnostic & Repair: From $225/hour + HST

Diagnostic vs. repair vs. maintenance — what’s the difference?
- Diagnostic: A licensed tech visits, tests your system, and provides a written explanation of issues. The fee covers travel and time to diagnose.
- Repair: We complete the approved fix per written quote. If a part is under warranty, that cost is deducted from the invoice.
- Maintenance: Preventative cleaning, calibration, and safety checks on working equipment. If we uncover a fault, we’ll provide options; maintenance can be combined with a discounted repair if needed.
Common furnace problems we fix — and what they usually mean
| Symptom | Likely Causes | Typical Next Step |
|---|---|---|
| Furnace won’t start | Tripped switch, failed ignitor, control board fault | Diagnostic and safety checks, replace faulty component if needed |
| Blowing cold air | Flame sensor dirty, gas valve issue, pressure switch fault | Clean/replace sensor, verify gas train, test pressures |
| Short cycling | Restricted airflow, dirty filter, oversized system, limit switch trips | Restore airflow, reset limit, check sizing and safeties |
| Loud banging/whistling | Duct static issues, loose panels, bearings, delayed ignition | Secure panels, adjust gas/air, assess blower or motor |
| Burning or electrical smell | Dust burn-off, wiring/overheat, motor windings | Safety inspection first, then targeted repair |
| Error codes on the board | Brand-specific diagnostics (Rheem, Lennox, Amana, etc.) | Retrieve code history, follow manufacturer decision tree |
If your system shows a safety issue, we’ll explain why, show you the readings, and provide options that fit your budget.

When to repair vs. replace: the Ottawa reality
| Situation | Repair Makes Sense When… | Consider Replacement When… |
|---|---|---|
| Age of furnace | Unit is under ~10 years and well-maintained | Unit is 12–20+ years with growing repair frequency |
| Cost of fix | Repair is minor/moderate and parts are available | Single repair is >30–40% of new system cost |
| Comfort & efficiency | Comfort is fine and bills are stable | Uneven heat, rising gas use, outdated tech |
| Safety findings | No red-tag, no chronic safety faults | Repeated safety trips or heat exchanger concerns |
Not sure where you land? We’ll compare the total cost of ownership and help you decide — repair first or replace for long-term savings. See our latest furnaces if a retrofit becomes the smarter play.
