HVAC Installation in London, ON: Why Sizing Matters
Incorrect equipment sizing is the most common and costly HVAC installation mistake in London homes. An oversized furnace or AC short-cycles, turning on and off too frequently, which wastes energy, creates humidity problems, and accelerates component wear. An undersized system runs constantly and still can't maintain comfort on the coldest January days or hottest July afternoons. Corner Gas HVAC performs a proper ACCA Manual J load calculation on every installation, accounting for your home's square footage, insulation levels, window area, ceiling height, and local London climate data. The result is a system sized precisely for your home.

Every installation by Corner Gas HVAC includes: safe removal and disposal of your old equipment, professional installation of the new system with all required gas and electrical connections, full system commissioning and performance verification, smart thermostat installation and programming, a complete homeowner walkthrough, and all required Ontario permits and inspections handled by our team. We also register your manufacturer warranty on your behalf and provide full documentation, so there is no paperwork for you.
