The right furnace depends on where you live

Ottawa. Most Ottawa homes heat with a natural gas furnace. Our Nepean office repairs and replaces furnaces across Ottawa, and you can buy, finance or rent.

Nova Scotia. Natural gas is limited in Nova Scotia, so most furnaces run on oil, with some propane. Our Dartmouth office repairs and replaces oil and propane furnaces in Halifax, Dartmouth and beyond.

Common furnace problems we fix

Gas furnace won’t light

Usually an igniter, flame sensor or pressure switch. These are often quick repairs.

Oil furnace smoke or soot

A dirty burner, a clogged nozzle or a worn filter makes an oil furnace burn poorly. A yearly cleaning keeps it safe and efficient.

Uneven heat or noisy airflow

On any fuel, cold rooms and rattling ducts usually trace back to airflow. We find the source before replacing anything.

Our TRALO™ guarantee

Every new furnace install is backed by our No Lemons Guarantee: if two or more major parts fail in the first 24 months, we replace the whole system.

And no surprises: the price on your written quote is the price you pay.

Furnace reviews

We had such an amazing experience with this company, specifically with Calvin and Stefanio. From the moment we reached out to replace our "ancient" furnace and central air, they were incredibly quick to respond to our query and had reprsentatives come to our home days later. They kept us updated every step of the way with open and clear communication - which was honestly refreshing. Every staff member we interacted with was friendly and thoughtful. Before starting any work, they walked us through the entire process, explained what to expect, and made sure we understood all the steps and comfortable with our decision. It never felt rushed, pressured or confusing — just honest, helpful guidance. A bonus we didn’t expect: they absolutely adored our dog, and the feeling was mutual. It made the whole visit feel so wholesome and comfortable. What really stood out was the continuous follow‑up afterward. They genuinely cared that everything was working perfectly and that we were happy with the service. Highly recommend — fast, friendly, transparent, and just an all‑around great experience.

FAQs

Furnace questions we hear every week

It depends on your home: the size of the house, your fuel (gas, oil or propane), your ductwork and your venting. That's why we offer a free assessment and give you a written quote with the full price. You can buy or finance, and in Ottawa you can also rent.

It depends on how you heat now and how old your system is. Heat pumps usually save the most when they replace oil, propane or electric heat. If you have natural gas and a newer furnace, the savings may be small. Many homes do best with both: a heat pump plus a furnace backup. Try our energy savings calculator for a rough idea.

Sometimes. If the repair is small and the furnace has been well maintained, fixing it can buy you a few more good winters. If it needs a big repair like a heat exchanger or control board, replacing it is usually the better use of your money. A cracked heat exchanger can leak carbon monoxide, so replacement is the safe choice there. We show you both numbers.

First check the thermostat is set to heat and the fan is on Auto, not On. Then check the filter: a clogged filter can make the furnace shut off its burner. If the air is still cold, it's often an igniter, a flame sensor or a blocked vent pipe. Turn it off and call us. If you smell gas, leave the house and call your gas utility's emergency line from outside.

Check the thermostat (set to heat, batteries working), the furnace power switch, the breaker and the furnace door, which has to be closed for it to run. If it still won't start, it's often a failed igniter, flame sensor or control board. Call us and we'll find the cause.

Most furnaces last about 15 to 20 years. Yearly maintenance, a clean filter and the right size for your home all help it last longer. If yours is past 15 years and needs a big repair, it's usually worth pricing a replacement. We'll tell you how yours is doing at your free assessment.

If two or more major parts of your new system fail in the first 24 months, we replace the whole system at no cost to you. Major parts include the compressor, coils, heat exchanger, reversing valve, fan and blower motors, and control board. Keep up with the recommended maintenance to stay covered. See our guarantees page for the full terms.
