Before you call

Basic Furnace Troubleshooting Before Calling for Service

Before scheduling a furnace repair, a few simple checks may help identify minor issues. These steps apply to many heating systems and may help restore operation temporarily.

  1. Finger pressing a button on a programmable wall thermostat

    Check the thermostat

    Confirm the thermostat is set to heat and the temperature is above room level. If using a digital thermostat, ensure batteries are functioning properly.

  2. Hand switching a breaker in a home electrical panel

    Check the circuit breaker

    A tripped breaker or switched-off furnace disconnect can stop system operation. Check your electrical panel and ensure the furnace power switch near the unit is on.

  3. Dirty pleated furnace filter being pulled out of a furnace

    Check the furnace filter

    A clogged filter can restrict airflow and cause the system to shut down. Replacing the filter may restore normal airflow and improve performance.

If you smell gas, don’t troubleshoot

Leave the house right away, and don’t use light switches or phones inside. From a safe distance, like a neighbor’s house, call 911 or your gas company (Enbridge Gas: 1-866-763-5427).

Regular maintenance helps reduce unexpected breakdowns and improve system performance. Our furnace tune-ups include safety checks, airflow inspection, component testing, and efficiency optimization to keep your heating system running reliably throughout the winter season.

Routine furnace maintenance helps extend system lifespan and maintain consistent heating performance. Annual inspections allow technicians to identify worn components, airflow concerns, and efficiency issues before they lead to system failure.

When to Consider a New High-Efficiency Furnace

If your furnace is over 15 years old, requires frequent repairs, or struggles to maintain consistent heat, replacement may be worth considering. Modern high-efficiency furnaces offer improved comfort, quieter operation, and reduced energy usage.

Our technicians provide in-home consultations to review available options and help determine whether repair or replacement is the better long-term choice based on system condition and household needs.

Questions

Furnace Repair FAQ

Furnace problems can happen suddenly, especially during colder months. These frequently asked questions help homeowners understand common furnace repair concerns, what causes issues, and when professional service is recommended.

Do you offer emergency furnace repair?

Yes. Emergency service is available. If your furnace has stopped working, call us at (519) 686-3595.

Why is my furnace running but not producing enough heat?

This can be caused by restricted airflow, thermostat settings, dirty filters, or internal component issues. A professional inspection can identify whether the problem is related to airflow, fuel supply, or system controls.

What are the most common signs that my furnace needs repair?

Common warning signs include uneven heating, unusual noises, frequent cycling, rising energy bills, or difficulty maintaining a consistent indoor temperature. Addressing these issues early can help prevent more serious damage.

How quickly can furnace repairs usually be completed?

Many furnace repairs can be completed during the initial service visit once the issue is diagnosed. More complex repairs may require additional time if parts are needed, but technicians typically provide clear next steps during the visit.

Is it safe to keep using a furnace that is not working properly?

Continuing to operate a malfunctioning furnace may lead to further damage or safety concerns. If you notice unusual smells, noises, or inconsistent performance, it’s best to have the system inspected as soon as possible. If you smell gas, leave the house right away. From a safe distance, like a neighbor’s house, call 911 or your gas company (Enbridge Gas: 1-866-763-5427).

Do you repair all furnace brands and system types?

We repair and service most of them: our technicians are trained to diagnose and repair a wide range of furnace brands and models. This includes gas furnaces, high-efficiency systems, and older units commonly found in residential homes. If yours is a make we cannot get parts for, we will tell you before we book the visit.

Should I repair my furnace or replace it?

It depends on three things: how old it is, how often it has needed work lately, and whether the repair is a small part or a major component. A fifteen-year-old furnace on its third repair in two winters is a different conversation from a newer unit with one failed sensor. We will give you our honest read on which side of that line you are on.

How can regular maintenance help reduce furnace repair needs?

Routine maintenance helps identify minor issues before they become major problems. Regular inspections, filter changes, and system adjustments can improve efficiency, extend equipment life, and reduce the likelihood of unexpected breakdowns.
