What a new furnace or heat pump costs in Guelph
A standard high-efficiency gas furnace typically costs $4,000 to $6,500 installed in Guelph, and a two-stage model $5,500 to $8,000, before HST. A ducted cold-climate heat pump typically runs $9,000 to $18,000, and dual fuel (a heat pump with a gas furnace as backup) $11,000 to $20,000.
Guelph sits inside the same Ontario ranges as everywhere else on FurnaceQuotes.ca. What moves your number is the house: thick stone walls to vent through, ducts never sized for central air, or a panel with no room for a heat pump circuit. Those show up far more in older homes.
- Single-stage gas furnace (95 to 96% AFUE)
- $4,000 to $6,500
- Two-stage gas furnace (96% AFUE, ECM blower)
- $5,500 to $8,000
- Modulating gas furnace (97 to 98% AFUE, variable-speed blower)

Older Guelph homes and newer ones get different quotes
The same furnace can be a one-day swap in the south end and a longer job in a century home near Exhibition Park.
Downtown, Exhibition Park and other older streets
- Stone and double brick walls. PVC venting has to be cored through a thick wall or routed another way. Budget $300 to $1,500 more when new venting or a liner is needed.
- Radiators in some homes. Cast iron radiators mean a boiler quote, not a furnace quote.
- Old chimneys. A gas water heater left alone on the chimney may need a liner.
- Ducts sized for heat only. Adding central air or a heat pump can mean new runs, typically $500 to $3,000+.
The south end and newer subdivisions
- Original builder-grade equipment reaching the age where repair or replace is a real question.
- Venting already in place. PVC venting and a condensate drain usually exist, so swaps are simpler.
- Ducts that already carry central air, which makes a ducted heat pump or dual fuel easier to add.
- Bigger homes, finished basements. Do not match the old size. Ask for a room-by-room heat loss calculation.
Furnace, heat pump or both?
Plenty of Guelph homeowners now want a heat pump price beside the furnace price. Get both priced in the same visit.
| Option | Typical range | Good fit when | Ask the company |
|---|---|---|---|
| Two-stage gas furnace | $5,500 to $8,000 | The AC is fine and you want the lowest upfront cost | AFUE, stages and blower type |
| Furnace and central AC | $8,000 to $15,000 | The AC is as old as the furnace | Does the indoor coil match the outdoor unit? |
| Dual fuel | $11,000 to $20,000 | You want to burn less gas but keep a furnace for the coldest days | At what outdoor temperature does it switch to gas? |
| Ducted cold-climate heat pump | $9,000 to $18,000 | The ducts are sound and the electrical service has room | Its cold-weather heating output and the backup heat |
Older homes can have a smaller electrical service. A heat pump circuit typically adds $500 to $2,500, and a panel upgrade, if needed, $2,000 to $4,500. Ask about the panel on the first visit. See what a heat pump quote should include.
Rebates: check before you sign
Ontario's Home Renovation Savings program offers heat pump rebates with eligibility rules by heating fuel, home type and product, and it requires approval before installation. Program rules change often, so check the official pages before you buy and never sign because of a promised rebate amount. New applications for the Canada Greener Homes Loan ended on October 1, 2025.

Fergus, Elora, Rockwood and Puslinch
The same request works outside the city; your postal code finds a participating company that serves your area. Two things change: who handles permits, and whether the house has natural gas.
- Fergus and Elora
- Township of Centre Wellington. Stone downtown homes raise the same venting questions as central Guelph.
- Rockwood
- Township of Guelph/Eramosa. Village homes plus rural properties, some off the gas network.
- Puslinch
- Township of Puslinch. Mostly rural. Homes without gas heat with propane, oil or electricity.

Common questions
Straight answers. If yours is not here, the company can answer it during your free estimate.
What does a new furnace cost in Guelph?
A standard high-efficiency gas furnace typically costs $4,000 to $6,500 installed, before HST, and a two-stage model $5,500 to $8,000. Older stone and brick homes can cost more when venting has to go through a thick wall or the ducts need changes. The number to rely on is a written quote after someone sees the house.
Does Guelph require a permit for a furnace replacement?
It depends on the work. Check with the City of Guelph before work starts, and have the contractor confirm in writing who handles any permit. Gas work needs a TSSA-registered contractor either way. In Fergus, Elora, Rockwood or Puslinch, your township handles permits, not the city.
Is a heat pump worth it in an older Guelph home?
It can be, but check the electrical panel, whether the ducts can move enough air, and how well the house holds heat. Many owners of older homes choose dual fuel, which keeps a gas furnace for the coldest days. Ask for a heat loss calculation and price both options in one visit.
Does Guelph's hard water affect my heating quote?
Only if the quote includes a combi boiler or tankless water heater. Both heat water through small passages that scale up faster with hard water. Ask what the manufacturer says about water hardness, whether a softener or scale filter is included, and how often the unit should be flushed.
