Separate suite furnace
A dedicated furnace for the suite gives each household its own heat and thermostat.
Two households, one house? We install furnaces and controls that keep upstairs and the suite comfortable without arguments over the thermostat.
No heat, no hot water or a gas smell? Call any time, day or night.
Surrey has some of the biggest family homes in the Lower Mainland, and many of them include a basement suite. When one furnace serves two households, someone is always too warm or too cold, and the shared ductwork can carry cooking smells, noise and smoke between units. A furnace installation in Surrey is often the moment to fix that properly.
Depending on the layout, we might install separate furnaces for the main house and the suite, split the ductwork, add zoning with separate thermostats, or pair a furnace upstairs with a ductless heat pump downstairs. Large two-storey homes in Fleetwood, Fraser Heights and South Surrey also benefit from two-stage or modulating furnaces. Everything starts with a heat loss calculation and a clear written quote.
The best setup depends on your floor plan and who lives where.

Dampers and separate thermostats can split one furnace into upstairs and downstairs zones.
A wall-mounted heat pump heats and cools the suite independently, without new ducts.
These adjust output in small steps, ideal for large open-plan homes with high ceilings.
New subdivisions get hot upstairs in summer, so many add cooling during the install.
Separating return air between units helps limit smoke and odours travelling between households.
Newton, Panorama Ridge and Sullivan have many large homes built in the 1980s through 2000s with basement suites added later, often without changing the original single-furnace layout. Fleetwood and Guildford mix older family homes with newer infill. Cloverdale and Fraser Heights include newer subdivisions where homes are tighter and summer heat is a growing concern.
In South Surrey, larger homes with high ceilings and big windows benefit from modulating furnaces and careful duct design. Wherever you are in Surrey, we look at the whole house, not just the furnace closet.
We ask who lives where, what bothers them now and how the suite is used.
You get options, from zoning to separate systems, each with clear pricing.
We coordinate with you and any tenants and keep work areas clean.
Every thermostat, damper and furnace is tested so both households are comfortable.
We work in homes with suites every week and know the practical options.
Each option is priced so you can weigh comfort against budget.
We work carefully in occupied suites and keep things tidy.
If either household loses heat, our technicians are available.
Still unsure? Call (236) 222-2222 and talk it through with us.
It can provide heat, but comfort and air separation are harder. Zoning helps with temperature; a separate furnace or ductless unit gives each household full control. We explain what suits your layout.
Many homeowners choose to separate air between units to limit smoke, odours and noise travelling through the ducts. Local requirements can apply, so we check how your home is set up and discuss options.
In big, open homes, modulating furnaces run longer at low output, which keeps temperatures steady and reduces drafts. They cost more up front, so we compare them with two-stage models for you.
Yes, and it saves time. We install a matching coil and outdoor unit together, or consider a heat pump that heats and cools.
Often it will, but it depends on the meter size and total appliance load. We calculate it and, if needed, help you arrange an upgrade with FortisBC.
