Furnace Installation in St. Thomas — What We Know About Your City
Every city has its own housing stock, climate patterns, and fuel infrastructure. Here's how we approach furnace installation specifically in St. Thomas and Elgin County.
St. Thomas's Older Homes
Many of St. Thomas's established neighbourhoods — particularly downtown and the east end near the Railway Museum — feature homes built in the 1950s through 1980s. These older homes often have original or once-replaced furnaces that are 20+ years old, oversized for today's better-insulated homes, and running at 60–70% efficiency. We size replacements correctly for modern insulation levels.
New Construction North & West Ends
St. Thomas's rapid growth has brought significant new residential development on the north and west edges of the city. New builds need properly designed HVAC systems from day one — correct sizing, appropriate venting, and equipment that qualifies for warranty coverage. We install for new construction in St. Thomas's newest subdivisions.
Rural Elgin County — Propane Properties
Many properties in Elgin County between St. Thomas, Aylmer, Dutton, and Shedden are on propane rather than the Enbridge gas grid. Propane furnace installation requires specific venting requirements, conversion kits, and licensing — not all HVAC companies in the area are properly equipped. We are fully experienced with propane system installations across rural Elgin County.
Lake Erie Influence on Climate
St. Thomas's proximity to Lake Erie creates climate patterns that affect HVAC sizing — lake effect moisture increases humidity, and the proximity to the lake can moderate temperatures compared to inland Ontario cities. Our heat load calculations account for Elgin County's specific climate data rather than using generic Ontario averages.

When to Replace Your Furnace in St. Thomas Ontario
Hawana provides honest repair vs replace advice. We tell you when a repair makes sense — and when replacement is the smarter investment.
Over 15 Years Old
Most furnaces in St. Thomas last 15–20 years. Many older St. Thomas homes still have original furnaces from the 1980s and 1990s — these are past their best and should be replaced.
Rising Energy Bills
An old 65–70% AFUE furnace wastes 30–35% of the gas it burns. Replacing it with a modern 96% AFUE unit cuts that waste by more than half — and pays for itself in energy savings.
Repair Cost Over 50%
If a repair costs more than 50% of a new furnace's installed price, replacement is almost always the smarter financial decision — especially on systems over 10 years old.
Cracked Heat Exchanger
A cracked heat exchanger leaks carbon monoxide and cannot be safely repaired on an older system. This is always a replacement situation — don't operate the furnace until it is replaced.
Uneven Heating
Cold spots in your St. Thomas home — particularly in older two-storey homes or homes with additions — often indicate an undersized or failing furnace that needs proper replacement sizing.
Unusual Noises
Banging at startup, grinding, or persistent rattling on a furnace over 12 years old usually means failing components. In most cases the cost to repair older failing equipment exceeds replacement value.

St. Thomas Furnace Installation Reviews
Rated 5 stars across 137 Google reviews — read all reviews ↗
"Hawana replaced our 25-year-old furnace in our downtown St. Thomas home with a new Lennox high-efficiency unit. They handled the permit, did a proper load calculation, and completed the installation in one day. The old furnace was barely keeping up — the new one heats our 1970s brick home perfectly and our gas bill has noticeably dropped."
"Had Hawana install a propane furnace at our rural property near Shedden in Elgin County. Not many HVAC companies are experienced with propane conversions but Abdullah knew exactly what to do. Clean installation, proper venting, passed inspection first time. Very happy with the service."
"We got three quotes for a new furnace in our north St. Thomas home and Hawana was the most competitive price for a comparable unit. The installation was professional, they cleaned up completely, and Abdullah took time to explain the Enbridge rebate process. Two months in and the new furnace is running perfectly."
