Common Questions
Frequently Asked Questions About HVACs in London
How much does HVAC installation cost in London?
A central air conditioner installation in London typically costs $3,500 to $7,500 including labour and equipment. A forced-air furnace replacement ranges from $2,500 to $5,500. A combined heat pump system can range from $5,000 to $15,000 depending on capacity and efficiency rating. Prices vary based on the size of your home and the efficiency rating of the unit chosen.
How often should I have my HVAC system serviced in London?
Most HVAC professionals recommend a professional tune-up once per year, ideally in spring before cooling season or in fall before heating season. Regular maintenance extends equipment life, maintains efficiency, and catches small issues before they become costly repairs. Changing air filters every one to three months between service visits is also important.
What should I ask before hiring an HVAC contractor in London?
Ask for proof of trade certification and gas fitting certification if gas work is involved. Confirm they carry liability insurance and WCB/WSIB coverage. Request a written quote that specifies the equipment model, warranty terms, and whether installation includes commissioning and removal of the old unit. Ask about available rebates from provincial or federal energy efficiency programs.
How long does it take to replace a furnace or air conditioner?
A straight furnace replacement typically takes four to eight hours. Installing a new air conditioner or heat pump usually takes six to ten hours including refrigerant line work. If ductwork needs to be modified or added, the job may extend to two days. Your HVAC contractor should provide a clear timeline as part of the written quote.
What is the average lifespan of an HVAC system in Canada?
Forced-air furnaces typically last 15 to 25 years with regular maintenance. Central air conditioners and heat pumps generally last 12 to 20 years. In London's climate, heating systems work harder and may age faster than in milder climates. If your system is more than 15 years old and requires a major repair, replacement often makes more financial sense.
