Should You Repair or Replace Your Furnace?

Repair usually makes sense when the unit is under about 12 years old and the failed part is a common one.

Repair if:

  • The furnace is under roughly 12 years old and has been maintained.
  • The fault is an igniter, flame sensor, pressure switch, blower capacitor or control board.
  • The heat exchanger passes inspection.

Replace if:

  • The heat exchanger is cracked (carbon monoxide risk, and the unit gets red-tagged).
  • The furnace is 18 years or older and mid-efficiency.
  • You’re facing a second major repair in two seasons.

Bottom line: a cracked heat exchanger or an 18-year-old unit means replace. Almost everything else on a maintained furnace is worth repairing. If replacement turns out to be the right call, ask us about switching to a heat pump instead of a like-for-like furnace swap, pairing the new furnace with central air conditioning for comfort year-round, or financing if the timing is tight.

Frequently Asked Question

We would recommend that you have your furnace serviced at least once a year. Ideally, it’s best to have it serviced before the start of the heating season, to ensure that it’s running efficiently and safely.

Regular maintenance can help prevent breakdowns and extend the lifespan of your furnace. During a service appointment, a qualified technician will inspect and clean the furnace, check for any signs of wear or damage, and make any necessary repairs or adjustments. They will also check the carbon monoxide levels to ensure that the furnace is not producing dangerous gases.

If your furnace is new or still under warranty, it’s especially important to keep up with regular maintenance to ensure that the warranty remains valid. Even if your furnace is running smoothly, it’s still a good idea to have it serviced annually to prevent any potential issues and to ensure that it’s operating at peak efficiency.

As an HVAC company, Just Air recommends that homeowners keep an eye out for the following signs that their furnace may need repair:

  1. Strange noises: If you hear banging, rattling, or other unusual noises coming from your furnace, it may be a sign that there is a mechanical issue.
  2. Weak airflow: If the airflow from your vents is weak or inconsistent, it could indicate a problem with your furnace’s blower fan or ductwork.
  3. Cold air: If your furnace is blowing cold air instead of warm air, it could be a sign that the pilot light is out, the thermocouple is malfunctioning, or there is a problem with the gas supply.
  4. Higher utility bills: If your utility bills have increased significantly, it could be a sign that your furnace is not operating as efficiently as it should be.
  5. Cycling on and off frequently: If your furnace is turning on and off frequently, it could be a sign of a malfunctioning thermostat or a problem with the furnace’s limit switch.

If you notice any of these signs, it’s important to have your furnace inspected by a professional HVAC technician as soon as possible to diagnose and repair any issues before they become more serious. Regular maintenance can also help prevent these problems from occurring in the first place.

The cost of furnace repair can vary depending on the extent of the damage and the specific repairs that are needed. On average, homeowners can expect to pay between $100 and $500 for a furnace repair, with some repairs costing more than $1,000 for complex issues.

Some common furnace repairs and their associated costs include:

  1. Replacing a faulty thermostat: $100 to $300
  2. Replacing a broken blower motor: $400 to $600
  3. Repairing a cracked heat exchanger: $500 to $1,500
  4. Fixing a gas valve: $150 to $400
  5. Repairing a pilot light or ignition system: $150 to $300

Keep in mind that these are just rough estimates, and the actual cost of your furnace repair may vary depending on your location, the age and condition of your furnace, and the complexity of the repair. Additionally, some HVAC companies may charge a diagnostic fee to diagnose the problem before providing an estimate for the repair.

It’s always a good idea to get multiple quotes from reputable HVAC companies before committing to a repair, and to weigh the cost of the repair against the potential cost of replacing an older, less efficient furnace.

There are a few factors to consider when deciding whether to replace or repair your furnace:

  1. Age of the furnace: If your furnace is more than 15 years old, it may be more cost-effective to replace it than to repair it, especially if it requires frequent repairs.
  2. Frequency of repairs: If you find yourself calling for furnace repairs more than once a year, it may be a sign that your furnace is reaching the end of its lifespan and needs to be replaced.
  3. Energy efficiency: If your furnace is not operating efficiently, it could be costing you more money in utility bills than it’s worth. Upgrading to a newer, more energy-efficient furnace could save you money in the long run.
  4. Safety concerns: If your furnace is emitting dangerous gases or has a cracked heat exchanger, it’s important to replace it for safety reasons.
  5. Cost of repairs: If the cost of repairing your furnace is more than half the cost of a new furnace, it may be more cost-effective to replace it.

Ultimately, the decision to replace or repair your furnace will depend on your individual circumstances and budget. A licensed HVAC technician can provide you with a professional assessment of your furnace and offer recommendations on whether repair or replacement is the best option for you.

A well-maintained gas furnace in an Ottawa home typically runs 15 to 20 years. Units that never get an annual service tend to fail closer to the 12-year mark. Ottawa’s heating season runs long, so total runtime hours matter more here than in milder parts of Canada, and skipping maintenance shortens that lifespan fast.

Check a one-inch filter every month and change it every one to three months during the heating season. Four and five-inch media filters usually last six to twelve months between changes. Homes with pets, a whole-house humidifier running, or nearby construction dust need filter checks more often than that schedule suggests.

A few common causes: the thermostat is set to FAN instead of AUTO, a clogged filter has tripped the high-limit switch, the igniter or flame sensor has failed, or the outside intake or exhaust vent is blocked. Check the filter and the vent first, then call for service if the furnace still blows cold air.

A furnace tune-up covers a full visual and mechanical inspection: checking the heat exchanger for cracks, testing the igniter and flame sensor, cleaning the burners and blower assembly, checking gas pressure and combustion, and testing the safety controls before the technician confirms carbon monoxide levels are in a safe range.
