What Hawana's Furnace Installation Price Includes
No surprises. Every item below is included in the written quote. If something specific to your home requires additional work (e.g., significant ductwork modification, gas line upgrade), it is identified at the estimate visit and included in the written quote before any work starts.
New Furnace Unit
The quoted brand and model at the quoted AFUE. 96% AFUE minimum on all gas installations. The unit installed is the unit described in the written quote.
Old Furnace Removal & Disposal
Disconnect, de-commission, remove, and properly dispose of the old unit. No additional disposal fee. The old furnace is gone when we leave.
Gas Line Connection
Connect the new unit to the existing gas supply line. If the supply line requires modification or upsizing (rare for direct replacement), this is identified at the estimate and quoted separately before work begins.
Electrical Connection
Connect the new unit to the existing furnace electrical circuit. If a new dedicated circuit is required, this is identified at the estimate and quoted before work begins.
Venting — PVC or B-Vent Adaptation
96% AFUE condensing furnaces use PVC direct-vent through an exterior wall. The transition from the old B-vent chimney flue to PVC direct-vent, including capping the old flue, is included in the installation price.
Condensate Drain Line
High-efficiency condensing furnaces produce condensate water as a byproduct of the secondary heat exchanger. The condensate drain line is connected to an appropriate drain as part of the installation.
Building Permit
Hawana pulls the building permit for every furnace installation in London Ontario and the surrounding municipalities. Permits are required by Ontario Building Code and ensure the installation is inspected and on record.
TSSA Gas Inspection
Every gas appliance installation in Ontario requires a TSSA inspection. Hawana schedules and completes the inspection as part of the installation. No additional inspection fees.
System Startup, Commissioning & Walkthrough
The new unit is started, combustion is confirmed, thermostat is programmed, and the homeowner receives a complete walkthrough of the new system including filter maintenance schedule.
Enbridge $650 Rebate Application
On qualifying 95%+ AFUE gas furnaces, Hawana submits the Enbridge Home Efficiency Rebate application after installation at no additional charge. The $650 cheque is mailed directly to the homeowner in 6–10 weeks.
What Size Furnace Does My London Ontario Home Need?
Correct furnace sizing is critical. An oversized furnace short-cycles — short bursts of high heat followed by off periods, which reduces efficiency and comfort and increases wear. An undersized furnace runs continuously and cannot maintain setpoint on a January morning at -20°C. Hawana performs a Manual J heat load calculation at every installation estimate.
| Home Size (sq ft) | Build Era | Recommended BTU/hr | Typical Model | Notes |
|---|---|---|---|---|
| Under 1,000 sq ft | Any | 40,000–50,000 | Goodman 40,000 BTU | Townhomes, small bungalows. One zone. |
| 1,000–1,400 sq ft | 2000+ | 50,000–60,000 | Goodman 60,000 BTU | Well-insulated newer homes. Standard recommendation. |
| 1,000–1,400 sq ft | Pre-2000 | 60,000–80,000 | Goodman 80,000 BTU | Older homes with higher heat loss. |
| 1,400–2,000 sq ft | 2000+ | 80,000 | Goodman 80,000 BTU | Most common London Ontario family home. Most common Hawana installation. |
| 1,400–2,000 sq ft | Pre-2000 | 80,000–100,000 | Goodman or Carrier 100,000 BTU | Older homes, higher heat loss, often poorly sealed. |
| 2,000–2,500 sq ft | Any | 100,000 | Carrier or Lennox 100,000 BTU | Larger homes. Two-stage or modulating unit recommended. |
| Over 2,500 sq ft | Any | 100,000–120,000 | Lennox or Carrier 120,000 BTU | Manual J assessment required. Multiple zones often appropriate. |
Manual J sizing at every estimate: The table above is a guide — not a substitute for a proper Manual J heat load calculation. Hawana performs a Manual J-based sizing assessment at every estimate visit. A correctly sized furnace for a specific London Ontario home accounts for ceiling height, window area and orientation, insulation values, air leakage, basement configuration, and the local design outdoor temperature of -20°C. Wren K.'s review below shows a real example: an older 100,000 BTU unit replaced with an 80,000 BTU unit after a proper sizing assessment confirmed the old unit was oversized.
Combo Furnace Installation Packages — London Ontario
When two aging systems need replacing, a combo installation saves on combined labour and permits. Both systems installed in one visit, one permit pulled, one inspection completed.
🔥 + ❄️ Furnace & Central AC
Gas furnace + central air conditioning installed in one visit. Ideal when both systems are aging or when you want full HVAC replacement in a single day rather than two separate installation visits.
- Goodman or Midea furnace + Goodman AC from $6,500
- Carrier or Lennox premium combo from $8,500
- One building permit, one gas + electrical inspection
- Enbridge $650 rebate on qualifying furnace portion
- Old furnace and old AC unit removed and disposed
- No rental on either unit
🔥 + 💧 Furnace & Navien Tankless
Gas furnace + Navien NPE tankless water heater installed in one visit. Replaces two aging systems in a single day. Particularly efficient on homes where both the furnace and water heater are approaching end of life simultaneously.
- Goodman furnace + Navien NPE tankless from $6,500
- Carrier or Lennox furnace + Navien from $8,200
- Shared gas line work done in one visit
- Enbridge $650 rebate on qualifying furnace portion only
- Old furnace and old water heater removed and disposed
- No rental on either unit
The Enbridge $650 rebate applies to the furnace portion only: In a combo installation, the $650 rebate applies to the qualifying gas furnace — not to the air conditioner or the tankless water heater. The total rebate remains $650. This is a common point of confusion — Hawana is explicit about this at every estimate so there is no disappointment after installation.
Furnace Venting Types — What London Ontario Homeowners Need to Know
Replacing an 80% AFUE B-vent furnace with a 96% AFUE direct-vent condensing unit is the most common furnace replacement scenario in London Ontario. Here is what that transition involves.
🡇 B-Vent — 80% AFUE Standard Efficiency
- Hot flue gases rise through B-vent chimney or shared flue
- Requires a working chimney or B-vent liner in good condition
- No condensate water produced — dry flue gases
- 80% AFUE: 20% of gas energy wasted as hot exhaust
- Does not qualify for Enbridge $650 rebate (under 95% AFUE threshold)
- Older London Ontario homes may still have this configuration
🔌 Direct-Vent PVC — 96% AFUE High Efficiency
- Cooled flue gases exit through PVC pipe penetrating an exterior wall
- Does not need a chimney — advantage for homes with deteriorated flues
- Produces condensate water — drain line required
- 96% AFUE: only 4% of gas energy wasted — $200–$300/yr savings
- Qualifies for Enbridge $650 rebate
- Old B-vent chimney capped — chimney repair cost avoided
What the B-vent to direct-vent transition involves: When replacing an 80% AFUE B-vent furnace with a 96% AFUE condensing unit, Hawana caps the old chimney flue, installs two 2-inch PVC pipes (intake and exhaust) through an exterior wall, and connects the condensate drain to an appropriate floor drain or laundry tub. If the water heater shares the chimney flue, a separate liner may be required for the water heater — this is assessed at the estimate visit and included in the written quote if required. Brig T.'s review below describes exactly this scenario at a Byron London home with a deteriorated chimney liner.
Furnace Brand Comparison — Goodman vs Carrier vs Lennox vs Napoleon
Hawana installs all major brands at published pricing. Here is an honest comparison of the brands most commonly installed in London Ontario homes.
| Attribute | Goodman / Midea | Napoleon / York | Carrier | Lennox |
|---|---|---|---|---|
| Price (gas, installed) | From $3,400 | From $3,800 | From $4,200 | From $4,200 |
| Price (propane) | From $3,900 | From $3,900 | N/A | N/A |
| Max AFUE | 96% | 96% | 98% | 98% |
| Enbridge rebate eligible | ✓ Yes | ✓ Yes | ✓ Yes | ✓ Yes |
| Modulating / variable | Two-stage available | Two-stage available | Infinity Greenspeed | Variable capacity |
| Noise level | Standard | Standard | Quiet (Performance+) | Quietest residential |
| Parts warranty | 10 years | 10 years | 10 years | 10 years |
| Parts availability (SW Ontario) | Excellent | Good | Good | Good |
| Best for | Budget, reliability, Enbridge rebate payback | Mid-range, Canadian brand (Napoleon), rural propane | Premium comfort, modulating output, quiet operation | Maximum quiet, premium comfort, variable capacity |
Hawana is brand-agnostic: The recommendation at every estimate is based on the homeowner's budget, home configuration, and usage pattern — not on which brand has the highest margin. Most London Ontario homes replacing a 15–25 year old furnace are best served by a Goodman or Napoleon 96% AFUE at the $3,400–$3,800 installed price point, which pays back the Enbridge rebate quickly and provides reliable, quiet operation. Carrier Infinity and Lennox variable-capacity are recommended for homeowners prioritising maximum comfort and noise reduction in open-plan living spaces.

Abdullah Ghzail — Lead HVAC Technician & Founder
Abdullah installs furnaces across London Ontario and Southwestern Ontario since 2018 — gas from $3,400 at published pricing before the visit because a homeowner who calls four companies and receives four vague quotes is not able to make an informed decision; Enbridge $650 rebate handled completely after installation because the homeowner should not have to navigate rebate paperwork on top of a furnace replacement; Manual J sizing at every estimate because an oversized furnace short-cycles in a 1,400 square foot Masonville semi-detached the same way it does in a 2,400 square foot Byron two-storey and the right size matters. Propane from $3,900 with LP propane TSSA certification. No rental. BBB A+. 138 five-star reviews.
Furnace Installation Reviews — London Ontario
138 five-star reviews — Manual J right-sizing (80,000 BTU instead of oversized 100,000), Lennox direct-vent with chimney capped in Byron, Goodman propane near Aylmer with honest LP explanation. Read all ↗
"Replaced our 19-year-old Carrier with a new Goodman 96% AFUE at our Masonville London home. The estimate from Hawana was the only one that included a specific BTU sizing calculation. The technician explained our 100,000 BTU old unit was slightly oversized and recommended 80,000 BTU — which costs less and runs more efficiently. Old furnace removed, new Goodman installed same day. Enbridge $650 rebate submitted by Hawana — cheque arrived 7 weeks later. Invoice matched the written quote exactly. No rental."
"Combo Lennox furnace and central AC at our Byron London home from $6,500. Furnace + AC combined was clearly better than two separate installs. The existing chimney flue was in poor condition — the technician explained the 96% AFUE Lennox direct-vents through PVC and the old flue could be capped, which avoided a chimney repair. Both units installed in one day. Enbridge $650 on the furnace portion. Two systems replaced, one visit, one permit. Exactly as described."
"Propane furnace near Aylmer — no natural gas. Hawana was one of two companies willing to quote propane and the only one with a clear published price. Goodman propane from $3,900. The technician confirmed LP certification and explained the burner and gas valve differences upfront — no other contractor even mentioned this. When I asked about the Enbridge rebate, the honest answer was it does not apply to propane rather than telling me what I wanted to hear. No rental, no monthly fee. Invoice matched the quote."
