HVAC System Installations
Installing a residential or commercial HVAC system isn’t just about hooking up machinery. It’s a multi-step process that includes calculating proper load size, selecting the right unit for the space, and setting up ductwork and electrical systems.
In London, ON, HVAC technicians ensure compliance with Ontario Building Code and local safety regulations.

A big part of what HVAC technicians do involves diagnosing issues.

HVAC techs use tools like multimeters, refrigerant gauges, and thermal imaging to pinpoint the issue. Common problems in London homes include clogged filters, refrigerant leaks, faulty thermostats, and worn-out motors. Technicians not only identify the issue but provide actionable solutions that prevent future breakdowns.
