Heating
Furnace replacement and installation in Eastern Ontario
The short answer
What furnaces do for a home
A furnace heats air at a central point and distributes it through ductwork. It remains the most common heating system in Eastern Ontario because it delivers high output on the coldest nights and works well with existing ducts.
The decisions that matter are whether repair or replacement is the better value, what capacity the house actually needs, and how the unit is vented and controlled. As a TSSA-registered heating fuels contractor we handle the fuel-side work along with the installation.
Who this is for
- Homes with a furnace at or past 15 to 20 years of service
- Households facing repeated repairs or parts availability problems
- Homeowners who want a furnace kept as backup heat for a heat pump
- Anyone with comfort complaints that the current system cannot resolve
Problems it solves
- Uneven temperatures between floors
- Noisy operation, rattling ducts, or a blower that never seems to stop
- Rising repair frequency or a failed heat exchanger
- A unit far larger than the house needs, producing hot-and-cold swings
How it works
In plain language
Fuel is burned in a sealed combustion chamber. A heat exchanger transfers that heat to indoor air without mixing combustion gases with it, and combustion products are vented outdoors.
A blower moves the heated air through supply ducts and returns cooler air for reheating. Modern variable-speed blowers and modulating burners run at partial output for longer periods, which produces steadier temperatures than single-stage equipment.
Efficiency is expressed as AFUE. High-efficiency condensing units extract additional heat from flue gases and vent through plastic pipe rather than a chimney, which changes the venting work involved in a replacement.
Ontario considerations
What this region does to the decision
- Eastern Ontario winters put furnaces under sustained load rather than occasional peaks, so combustion setup and airflow verification matter more here than in milder regions.
- Many Ottawa-area homes were built for chimney-vented mid-efficiency equipment. Converting to a condensing furnace requires new sidewall venting and condensate drainage, and sometimes attention to an orphaned water heater left on the old chimney.
- Fuel-burning work in Ontario falls under TSSA oversight. Our registration number is 000202850.
Options
Common configurations
- Single-stage furnace
- One output level. Lowest purchase cost, largest temperature swings.
- Two-stage furnace
- Runs at reduced output most of the season and full output on the coldest days. A practical middle option.
- Modulating furnace with variable-speed blower
- Adjusts output and airflow continuously. Quietest and most consistent, and the best match if a heat pump will be added later.
Sizing and design
- We calculate heat loss for the house instead of matching the label on the old unit, because replacements installed decades ago were routinely oversized.
- Duct capacity is measured as well. A larger furnace pushed through undersized ducts is noisy and short-lived.
- If a heat pump is likely within a few years, we select a furnace that will work correctly as its backup.
Installation and what to expect
- Written scope, equipment model, venting plan, and price before scheduling.
- Permits and safety documentation for the fuel work.
- Safe decommissioning and removal of the old appliance.
- New venting, gas connections, condensate drainage, and electrical as required.
- Combustion analysis, airflow measurement, and safety checks recorded at commissioning.
- A walkthrough of controls, filter access, and maintenance intervals.
Financing
Furnace replacement is often unplanned. Financing through Financeit can spread the cost, subject to the provider's approval and terms.
Financing is provided by Financeit to qualified applicants. Approval, rates, terms, and product eligibility are determined by the financing provider.
Support after installation
- Annual service before the heating season: combustion, venting, safety controls, and airflow.
- Filter changes every one to three months keep the blower and heat exchanger within design conditions.
- Warranty and labour terms appear in your written proposal.
