How Much Does a HVAC Repair Cost in London? (2026 Guide)
Quick Answer
In 2026, London homeowners can expect to pay between $150 and $500 for professional HVAC repairs. The average cost sits at approximately $325 per service call. Prices vary based on the complexity of the issue and required parts. Notably, the high density of older housing stock in historic London neighbourhoods often leads to more complex, site-specific repair challenges.

Note: The 13% HST is mandatory on all HVAC services in Ontario and is not included in the ranges above. Emergency after-hours calls may incur an additional "premium" fee ranging from $50 to $150 on top of these standard rates.
What Affects HVAC Repair Pricing in London
Understanding why quotes vary is key to managing your home maintenance budget. In London, several unique local factors influence the final bill:
1. Housing Stock Age
London is home to a diverse mix of architecture, from the heritage homes of Old South to the mid-century builds in Oakridge. Older homes often feature non-standard ductwork or outdated electrical setups, which can increase the time required for a technician to access components, thereby increasing labor costs.
2. Distance from Suppliers
While London has a strong network of supply houses, technicians traveling to the city's expanding periphery—such as the rapid developments in the southwest or the North London fringe—may charge a higher travel surcharge to account for fuel and time spent navigating the city's traffic during peak hours.
3. Local Labor Market
With 187 contractors in our local database, London offers a healthy, competitive market. However, skilled trades are in high demand across Ontario. Technicians with specialized certifications for high-efficiency boilers or complex heat pump systems often command higher hourly rates than those performing basic furnace maintenance.
4. Seasonal Demand
London experiences extreme temperature swings. During the first cold snap in November or the first humid week in July, demand for HVAC services spikes. When contractors are fully booked, pricing for non-emergency repairs can fluctuate as demand outstrips the available technician supply.
5. Property Accessibility
For homeowners in older downtown apartment conversions or homes with tight utility closets, physical accessibility is a major factor. If a technician needs to dismantle shelving, move heavy equipment, or work in a cramped crawlspace, the labor component of the quote will rise to reflect the added effort.
Best Time to Hire a HVAC Repair in London
The smartest way to manage your HVAC budget is to avoid the "emergency cycle." In London, the demand for service follows the thermometer. The peak periods—usually mid-November (when the furnace is first fired up) and late June (when AC is needed)—are when you will find it most difficult to secure a convenient appointment, and prices for urgent repairs may feel higher due to "emergency" surcharges.
The best time to schedule routine repairs or non-urgent maintenance is during the "shoulder seasons": April to May and September to October. During these months, local contractors are less overwhelmed, and you are more likely to find promotional pricing on service plans or maintenance packages. By scheduling your repair during these periods, you ensure your system is ready before the London weather becomes punishing, allowing you to bypass the premium fees associated with last-minute, emergency callouts.
How to Save Money on HVAC Repair Services in London
Get Multiple Quotes: With 187 contractors available, never settle for the first price. Obtain at least three quotes from reputable London-based firms to ensure you are paying market rates.
Bundle Maintenance: If you have an upcoming furnace repair, ask if the technician can perform your seasonal AC tune-up at the same time. Bundling services often saves on the "trip fee" component of the invoice.
Check Rebate Programs: While repairs are rarely covered by government grants, significant upgrades (such as replacing an old, inefficient motor with an ECM motor) may qualify for utility incentives. Always ask your contractor if the repair path you’re choosing is eligible for local energy efficiency rebates.
Off-Season Scheduling: As mentioned, avoid the peak freeze or heatwave. Schedule repairs in the spring or fall to take advantage of more flexible scheduling and potential off-season discounts.
Ask About Service Plans: Many London HVAC companies offer annual service memberships. These often provide priority booking, discounted hourly labor rates, and waived emergency service fees, which can pay for itself in a single breakdown event.
Finding a Licensed HVAC Repair in London
In Ontario, your safety and the longevity of your equipment depend on hiring a qualified professional. Ensure that any company you hire holds a valid TSSA (Technical Standards and Safety Authority) license. This is the gold standard in Ontario for gas and heating work.
Before a technician starts work, ask these three questions:
Are you TSSA certified? (They should be able to provide a certification number).
Do you have WSIB coverage? This protects you, the homeowner, from liability in the event of an accident on your property.
Do you carry comprehensive general liability insurance? A minimum of $2 million in coverage is standard for professional contractors.
You can verify a contractor's status through the TSSA's "Find a Contractor" tool online. Additionally, look for local London reviews on platforms like GetAHomePro or Google Maps to ensure the company has a strong reputation for transparency and workmanship within the local community.
Frequently Asked Questions
Does a routine tune-up usually catch major issues?
Yes, a professional tune-up allows a technician to inspect electrical connections and heat exchangers. This often reveals wear and tear before it becomes a complete system failure, saving you from a costly emergency repair.
Is there a difference in cost between furnace and AC repair?
Generally, AC repairs can be slightly more expensive if they involve refrigerant, as the materials are regulated and specialized. However, complex furnace issues involving circuit boards or inducer motors can also reach the high end of the $500 range.
Do I need a permit for HVAC repairs in London?
Routine repairs and component replacements typically do not require a building permit. However, if you are performing a full system replacement or relocating equipment, you must check with the City of London’s Building Division regarding local bylaws.
How long should I expect to wait for a repair appointment?
During off-peak times, you can often get an appointment within 24–48 hours. During the peak of winter or summer, wait times for non-emergency issues can extend to 3–5 days depending on the contractor’s availability.
Should I repair or replace my old system?
If your repair costs exceed 50% of the value of your unit, or if the unit is over 15 years old, replacement is usually the more cost-effective long-term choice. Ask your technician to provide a cost-benefit analysis before you commit to an expensive repair.
