Furnace Installation in Newmarket
Furnace installation in Newmarket, done as a complete job: correct sizing, a written quote, careful installation and full testing. All Nation Comfort installs furnaces across Newmarket, York Region and the GTA.
Heating installation
A new furnace, sized and installed properly.
A furnace that is too big short-cycles and wears out early; one that is too small never quite keeps up on the coldest nights. Our furnace installation in Newmarket starts with your home — its size, ductwork and existing venting — so the new system is matched to the house, not just swapped box-for-box.
We handle the full job: removing the old unit, setting the new furnace, connecting gas, venting and condensate, and testing the system through a complete heating cycle before we leave. Floors are protected and the work area is cleaned up, the same way we work on every job across York Region and the GTA.
When replacement makes sense
- Furnace is 15–20 years old and needing repeat repairs
- Heat exchanger or major component failure
- Rising heating bills with uneven heat
- Frequent breakdowns during cold weather
- You are renovating or finishing a basement
- Converting or upgrading an older heating system
How the job goes
What to expect.
Home visit and sizing
We look at your home, ductwork and current system, and talk through how you use the space so the furnace is sized correctly.
Written quote
You get clear options — equipment, scope of work and cost — before anything is booked. Questions are answered up front.
Installation day
The old furnace comes out and the new one goes in: gas line, venting, condensate and thermostat connections, done to code.
Testing and walkthrough
We run the system, check airflow and safeties, register the equipment warranty details with you, and show you how everything works.
Equipment
Brands we work with.
We install Kepler, Lennox and Goodman furnaces — high-efficiency systems suited to Ontario winters, backed by the manufacturer warranty, with help from us on the warranty details when the installation qualifies. If the old furnace has already quit, our furnace repair in Newmarket page explains how a repair visit works.
