Book the Right Furnace Repair Visit
Most active heating problems should begin with a diagnostic visit. The goal is to find the cause before replacing parts or recommending a larger repair. Current rates and availability can be confirmed when you book.
Regular Diagnostic & Repair
From $149/hr + HSTBest for furnace problems during regular business hours, including no heat, weak airflow, short cycling, unusual noises, error codes, or a furnace that will not stay running.
After-Hours Heating Help
From $225/hr + HSTAvailable when your schedule or comfort needs do not fit a regular daytime appointment. Higher charges may apply on statutory holidays or urgent calls.
Emergency Furnace Repair
24/7 No-Heat SupportUse emergency service when waiting is not practical, such as a no-heat situation during very cold weather, overnight furnace failure, or a heating issue that may make the home unsafe.
Parts are quoted before work proceeds. Final cost depends on diagnostic time, the part or component involved, equipment condition, access, appointment type, and current availability.
Furnace Problems We Diagnose
A furnace problem can come from the thermostat, filter, airflow, ignition system, flame sensor, pressure switch, venting, condensate drainage, blower, safety controls, gas valve, control board, or electrical components. A diagnostic visit helps narrow the cause before repair options are recommended.
What to Tell Our Team
You do not need to diagnose the furnace yourself. A few details help our dispatch team book the correct visit and prepare the technician for what is happening in your home.
Describe the symptom
Tell us whether you have no heat, weak heat, short cycling, a furnace that will not start, a new noise, a smell, or an error code.
Check simple items
Confirm the thermostat is set to heat, the temperature setting is above room temperature, the furnace switch is on, and the filter is not badly clogged.
Share urgency
Let us know whether the home has no heat, whether anyone is vulnerable to cold temperatures, and whether the problem can wait for regular scheduling.
Do not keep resetting a furnace that repeatedly fails. Repeated resets can hide the symptom without correcting the cause and may delay proper diagnosis.
What Happens During a Furnace Repair Visit?
A good furnace repair visit should not feel like guesswork. The technician checks the heating sequence, identifies where the system is failing, and explains the practical repair options.
1. Review the symptoms
We start with what you are experiencing, including no heat, cool air, short cycling, ignition trouble, error codes, unusual sounds, or weak airflow.
2. Test the system
The technician checks the thermostat, filter, airflow, ignition, safety switches, venting, condensate drainage, blower operation, gas-related components, and electrical controls as needed.
3. Explain the next step
You receive clear options based on the cause of the problem, the condition of the furnace, parts availability, repair value, and long-term comfort.
Emergency Furnace Repair for No-Heat Situations
If your furnace fails overnight, during a weekend, or during very cold weather, waiting for a regular appointment may not be practical. AirZone provides emergency HVAC service when comfort and safety cannot wait.
Use emergency service for urgent no-heat calls, repeated furnace shutdowns, unsafe equipment concerns, or situations where vulnerable people in the home may be affected by the loss of heat.
Choose the Right Heating Visit
Furnace repair, furnace maintenance, and emergency heating service solve different problems. The right visit depends on what your system is doing today.
Furnace repair
Your system is not heating, blowing cool air, short cycling, displaying error codes, making new noises, or failing to stay on.
Furnace maintenance
Your system is working, but you want a seasonal cleaning, safety check, airflow check, and preventative inspection before peak heating season.
Emergency service
The home has no heat, the failure happened at night or on a weekend, or waiting for a regular appointment may create a safety or comfort problem.

Should You Repair or Replace Your Furnace?
Not every furnace problem means replacement. Repair may be the right move when the furnace is newer, has been maintained, and the issue is isolated. Replacement may be worth considering when the furnace is older, inefficient, unreliable, difficult to service, or facing a repair that is expensive compared with the value of the equipment.
Repair may make sense when:
The furnace normally heats the home well, this is the first meaningful repair, the part is practical to replace, and the repair is likely to extend useful life without creating a pattern of service calls.
Replacement may be smarter when:
The furnace is old, repeatedly failing, expensive to repair, noisy, inefficient, difficult to source parts for, or no longer keeping the home comfortable during Ottawa winter weather.
A Furnace Problem Can Affect More Than Heat
In many Ottawa homes, the furnace blower also moves air for the central air conditioner. If the blower, control board, airflow, indoor coil, or electrical components are affected, the issue can create comfort problems in both heating and cooling seasons.
If water damage, repeated faults, airflow problems, or an older furnace are part of the repair discussion, AirZone can help you compare the practical next step, including repair, furnace replacement, indoor coil considerations, or future heat pump compatibility.

Red-Tagged Furnace? Ask for a Second Opinion
A red tag means a gas appliance has been identified as unsafe or non-compliant and may need to be shut off until the issue is corrected. This is different from a normal furnace repair because safety, code compliance, and documentation become the priority.
If your furnace has been red tagged, AirZone can review the situation, explain what the red tag means, and provide a clear plan for correction or replacement where needed. Do not continue operating equipment that has been identified as unsafe.
Answers Before You Book a Furnace Repair Visit
What should I check before booking furnace repair?
Check that the thermostat is set to heat, the temperature setting is above the current room temperature, the furnace switch is on, and the breaker has not tripped. You can also check whether the filter is badly clogged and whether supply and return vents are open. If the furnace still will not run normally, book a diagnostic visit.
Why is my furnace running but blowing cool air?
A furnace that blows cool or lukewarm air may have an ignition problem, flame sensor issue, restricted airflow, overheating condition, thermostat problem, blower timing issue, or another fault in the heating sequence. A technician can test where the furnace is failing and explain the repair options.
How much does furnace repair cost in Ottawa?
Cost depends on diagnostic time, the part or component involved, equipment condition, access, and whether the visit is during regular hours, after hours, or an emergency call. AirZone’s regular diagnostic and repair service currently starts at $149 per hour plus HST, while after-hours and emergency rates currently start at $225 per hour plus HST. Confirm current rates when booking.
Do you offer emergency furnace repair in Ottawa?
Yes. AirZone provides emergency HVAC service for urgent no-heat situations, overnight furnace failures, weekend heating problems, and situations where waiting for a regular appointment may create a comfort or safety concern.
Is furnace repair different from furnace maintenance?
Yes. Furnace repair is for an active problem, such as no heat, short cycling, ignition failure, weak airflow, error codes, unusual sounds, or a furnace that will not stay running. Furnace maintenance is preventative and is scheduled before there is a breakdown. For preventative service, visit the annual maintenance page.
Should I repair my furnace or replace it?
Repair often makes sense when the furnace is newer, maintained, and facing an isolated issue. Replacement may be worth considering when the furnace is older, inefficient, repeatedly failing, difficult to service, or facing a repair that is expensive compared with the value of the system.
Can a flooded basement damage my furnace?
Yes. If water reached the furnace cabinet, blower area, controls, wiring, gas components, or connected indoor equipment, the furnace should be reviewed before use. Visit our flooded basement HVAC page for more guidance.
