Furnace repair costs in London, ON typically range from $150 to $600 depending on the part and complexity of the repair. A diagnostic call is $89 and is waived when you proceed with the repair. We provide a written quote before any work begins so there are never any surprises.

Most furnace or central air conditioner installations in London, Ontario are completed in a single day, usually 4 to 8 hours. Heat pump installations may take slightly longer. We schedule around your availability and clean up fully before we leave.

London homeowners can access the Canada Greener Homes Grant (up to $5,000) and the Ontario Home Efficiency Rebate Plus program for qualifying heat pump installations. Some rebates reach $10,600 when combined. We handle all the paperwork and rebate applications on your behalf.

We recommend annual maintenance for both your furnace (ideally in the fall before heating season) and your air conditioner (in the spring before cooling season). Regular tune-ups extend equipment life by 5 to 7 years, improve efficiency, and catch small issues before they become costly repairs.
