Furnace installation & replacement in Kelowna
When a furnace is past its life, the replacement should be sized to your house, not just matched to the old label. We size it, install it, and connect the gas, venting and condensate drain under a gas permit.

Quick answer
For furnace installation or replacement in Kelowna, call Anderson Plumbing and Gas Fitting at (250) 859-3548. Gas furnaces sized for the home, with the gas line, venting and condensate drain connected under permit by a gas contractor licensed with Technical Safety BC (LGA0212697).
Once a furnace is past roughly 15 years and facing a major repair, replacing it is often the better long-term move. A newer high-efficiency furnace uses less gas for the same heat, and you stop paying to keep an old one going through another winter. We look at the existing furnace first and tell you if a repair makes more sense.
Size matters more than most people think. A furnace that is too big for the house short-cycles, heats unevenly and wears out sooner. One that is too small runs constantly on the coldest nights. We check the size against the house, not just the label on the old unit.
The gas and venting are where installs go wrong. High-efficiency furnaces usually vent through the wall in plastic pipe and need a drain for condensate, and taking a furnace off a shared chimney can leave a gas water heater venting into a chimney that no longer suits it. As a gas contractor licensed with Technical Safety BC (LGA0212697), we handle all of it under permit.
Services covered
Furnace replacement
Gas furnace installation: old furnace out, new one sized for your home, connected to the gas, venting and thermostat, started up and checked before we leave.
Venting and condensate
New venting and a condensate drain for high-efficiency units, plus a check that your water heater still vents safely afterwards.
Gas furnace hookup
The gas line resized if the new furnace needs more gas, with a shut-off valve and sediment trap at the unit and a gas pressure check at startup.
Thermostats
A new or programmable thermostat set up with the furnace, where the existing wiring supports it.
Permit and paperwork
Every gas furnace install needs a gas permit. Inside Kelowna, the City of Kelowna issues most natural gas permits. Propane work, and all gas work in West Kelowna, Lake Country, Vernon, Peachland and Oyama, is permitted through Technical Safety BC. We pull it, and we can put the permit number and our licence number on your invoice, which FortisBC rebates ask for.
Signs it may be time for a new furnace
- The furnace is getting old and needs a major repair
- A repair quote is a big share of the price of a new unit
- Heat is uneven, or some rooms never warm up
- Heating bills keep climbing
- A safety problem was found during a service
Repair or replace your furnace?
What we look at before recommending a new furnace.
Age
Past roughly 15 years, a major repair is often money put into a unit that is near the end anyway.
Size of the repair
If the repair is a big share of the cost of a new furnace, replacing usually wins over the next few winters.
Safety findings
Some problems found during a service, like a cracked heat exchanger, mean the furnace should not keep running until it is fixed or replaced.
Comfort
Uneven heat, rooms that never warm up, or a furnace that runs and runs can point to the wrong size unit as much as a failing one.
Bills
Gas bills climbing without a clear reason often mean the furnace is losing efficiency.

About usQuestions, answered
Can you look at my old furnace before quoting a new one?
Yes. We look at the existing furnace first, and if a repair makes more sense than a replacement, we tell you and price the repair instead.
Do I need a permit to replace a gas furnace?
Yes. Installing a gas furnace needs a gas permit and a licensed gas contractor. Inside Kelowna, the City of Kelowna issues most natural gas permits. Propane work, and all gas work in West Kelowna, Lake Country, Vernon, Peachland and Oyama, is permitted through Technical Safety BC. Under our gas contractor licence (LGA0212697), we handle the permit.
Will a new furnace affect my water heater?
It can. If the old furnace and a gas water heater share a chimney, removing the furnace can leave the water heater venting poorly. We check this on every replacement and fix it as part of the job if needed.
How much does a new furnace cost?
It depends on the size of furnace your home needs, the venting, and whether the gas line needs work. We look at your setup and give you a fair, upfront price, permit included, before we start.
Are there rebates for a new furnace?
Programs change often. FortisBC has rebates for homes switching their heat to natural gas, and furnace rebates for income-qualified households. The CleanBC rebate search tool helps you find programs by address. Tell us what you have now and we will help you check what applies before you buy.
