Energy-Efficiency Upgrades for Older Homes in BC: An East Hill Guide
Quick answer: For most older East Hill homes, the best order is: air sealing and attic insulation first, then heating upgrades such as a heat pump, then windows and doors. In Vernon, electricity comes from BC Hydro and natural gas from FortisBC, and both deliver rebates under the CleanBC Better Homes and Home Renovation Rebate programs. Check current amounts before you start.
East Hill has some of Vernon's oldest housing, from 1890s landmarks like the Caetani Cultural Centre's Sommerville house to homes built across the following century. Many of these houses were built long before modern insulation standards. That makes them drafty and expensive to heat, but it also means well-chosen upgrades can make a real difference in comfort and running costs.
This is general information. Rebate programs and eligibility change often, so confirm details with BC Hydro, FortisBC or the CleanBC Better Homes program, and talk to a qualified contractor before you commit.
Start With the Building Envelope
Energy advisors generally recommend fixing the "envelope" (the shell of the house) before replacing heating equipment. A tighter, better-insulated house needs a smaller, cheaper heating system.
Air sealing
Older homes leak air through gaps around windows and doors, attic hatches, plumbing and wiring holes, and where the house meets its foundation. Sealing these leaks is usually the least expensive upgrade and one of the most noticeable.
Attic insulation
Heat rises, so a poorly insulated attic is often the biggest energy loss. Before adding insulation, a contractor should check for old knob-and-tube wiring, which should not be buried under insulation, and for older loose-fill products that need testing before they're disturbed.
Walls and basements
Insulating the walls of an older house is trickier and often best done when you're already renovating or re-siding. Basement and crawl space insulation can be easier and helps with cold floors.
Heating and Hot Water
Heat pumps
Heat pumps provide both heating and cooling, which is a real benefit in an Okanagan summer. Modern cold-climate models are designed to work through Interior winters, though many homes keep a backup heat source for the coldest days. Older homes without ductwork can use ductless mini-split systems.
Heat pump water heaters
These use far less electricity than a standard electric tank and are included in current rebate programs.
Check your electrical service
Older homes may have smaller electrical panels. Adding a heat pump, an electric vehicle charger or a suite can mean a panel upgrade, so get an electrician's assessment early.
Windows and Doors
Replacing windows is often the most expensive upgrade and not always the best value. In a character home, original wood windows are also part of what gives the house its look.
- Repair and weatherstrip original windows where possible.
- Add storm windows to improve performance while keeping the originals.
- Replace when frames are failing, choosing styles that suit the house.
If your home is protected under a City of Vernon heritage designation bylaw or heritage revitalization agreement, exterior changes like window replacement need a Heritage Alteration Permit. Check with the City first.
Rebates and Programs to Check (as of 2026)
- Home Renovation Rebate Program: Offered by BC Hydro and FortisBC in partnership with the Province under CleanBC Better Homes. It covers upgrades including heat pumps, heat pump water heaters, insulation, and windows and doors. Applications go to either BC Hydro or FortisBC depending on your home and heating system, so check the program site to see which applies to you.
- CleanBC Better Homes Energy Savings Program: An income-qualified program with enhanced support for eligible households.
- Federal programs: The Canada Greener Homes Grant has closed, and the Canada Greener Homes Loan stopped taking new applications in October 2025. Check Natural Resources Canada for anything new.
Most programs require using qualifying equipment and, in many cases, eligible contractors. Some require pre-approval or have deadlines after installation. Read the rules before work begins, not after.
Other Upgrades Worth Considering
- Radon testing: Health Canada recommends testing every home. If you're sealing up an older house, it's smart to know your levels.
- Ventilation: A tighter house needs good ventilation. Bathroom and kitchen fans that vent outside, or a heat recovery ventilator, keep indoor air healthy.
- Smart thermostats: Low cost and easy, especially for homes with zoned heat.
Energy upgrades can also help when it's time to sell. Buyers of older homes often ask about heating costs and recent improvements. Our guide to selling in East Hill explains how to present these upgrades, and our FAQ covers common questions about older homes.
