Furnaces in Ottawa, ON
Furnace installation, replacement, repair and service across Ottawa
Ottawa winters are long and severe, with stretches well below minus twenty, so a reliable furnace is not a comfort but a safety necessity. The decision a homeowner faces is rarely whether to heat, but which furnace to choose and which company to trust: properly TSSA-registered, using a certified gas technician, insured, fairly priced and tidy. This independent guide explains how a new furnace is priced, when to repair versus replace, how servicing keeps gas bills and breakdowns down, and how to compare local companies with confidence.
Ottawa Furnace Pros is an independent local guide. We are not a furnace installer and we do not install, replace, repair or service furnaces ourselves. We help Ottawa-area homeowners understand furnace installation, replacement, repair and maintenance, and connect with TSSA-registered, insured and vetted local companies for free, no-obligation quotes.
Furnace installation and replacement
Whether you are replacing an old, failing unit or fitting a high-efficiency furnace, sizing and installation are what determine comfort and running cost. We cover new installs and replacements on our furnace installation page.
Furnace repair
When a furnace stops heating, short-cycles, trips or makes new noises, prompt repair avoids a no-heat emergency in deep cold. See our furnace repair page for common faults and how repairs are priced.
Furnace service and maintenance
An annual service before winter cleans the filter, checks the burners, heat exchanger and venting, and keeps the furnace safe and efficient. Our furnace service page explains what a service covers and how often to do it.

Compare vetted furnace companies near you
Tell us a little about your home, whether you need a new furnace, a replacement, a repair or a service, and we will help you compare TSSA-registered, insured Ottawa-area companies and request free quotes. There is no obligation, and reputable companies assess the home before giving a firm price.
This page is general information, not professional advice. Every home and furnace is different, and only a qualified, TSSA-registered company can confirm the right system, capacity, scope and price after assessing your home. Always verify a company's current TSSA registration, gas-technician certification, insurance and WSIB coverage before signing a contract. Gas and electrical work is regulated for safety; using a licensed company is the safe and legal choice.
Frequently asked questions
There is no single price: it depends on the size and efficiency (AFUE) of the furnace, the layout and age of your home, whether ductwork or venting needs changing, and any electrical or gas-line work required. We do not quote a figure. A TSSA-registered local company gives you an exact price after assessing the home. As a rough guide, a new high-efficiency gas furnace installed typically runs several thousand dollars, more for larger homes or complex installs. Ask what is included (the furnace, installation, venting, permits, and removal of the old unit) so you can compare like for like. This page is general information, not a quote.
A newer furnace with a one-off fault is usually worth repairing. An older unit (roughly 15 or more years) that needs a major repair, runs inefficiently, or breaks down repeatedly is often cheaper to replace with a high-efficiency model than to keep patching, especially given Ottawa winters where a mid-winter failure is a safety issue. A good company gives you the honest comparison rather than defaulting to the bigger sale. Always get the diagnosis and options in writing.
Yes. In Ontario, gas appliance work must be done by a TSSA-registered contractor using a certified gas technician (G1 or G2), and the electrical connection by a licensed electrician (ESA). Using an unregistered installer can void the manufacturer warranty, breach the law, and create serious safety and insurance problems with a gas appliance. Always verify the company holds current TSSA registration and gas-technician certification, carries insurance, and has WSIB coverage, before work begins. Get the model, capacity and scope in writing.
AFUE (Annual Fuel Utilization Efficiency) is the percentage of fuel a furnace turns into usable heat. A high-efficiency condensing furnace is typically 95% AFUE or higher, versus older units around 60-80%. A higher AFUE generally means lower gas bills for the same heat, but the real saving depends on your home insulation, how cold the winter is, and your gas rate. A good installer sizes the furnace correctly for your home, since an oversized or undersized unit wastes money and comfort either way.
Most furnaces benefit from a service once a year, ideally in autumn before the heating season, to clean or replace the filter, check the burners, heat exchanger and venting, and confirm safe, efficient operation. Annual maintenance keeps gas bills down, extends the life of the unit, protects the warranty (many require it), and catches faults like a cracked heat exchanger before they become a safety risk. A company can set up a simple maintenance schedule for your furnace.
