Founded in 2019, Kelvin Mechanical has grown into a trusted Ontario home comfort and mechanical service company focused on honest advice, clean workmanship, and long-term customer care. Named in honour of Lord Kelvin, we keep Ontario homes comfortable with trusted HVAC, Water Heating & Plumbing Support, Electrical & Energy, and commercial mechanical services — from furnaces and air conditioners to water heaters, water treatment connections, EV chargers, lighting, and solar.

Our licensed technicians bring the same standard to every visit: clear communication, respectful work in your home, and no upselling just the right solution for your space and your budget. Whether it's a brand-new installation, an urgent repair, or a seasonal tune-up, we treat every job like it's in our own home.

We proudly carry leading HVAC and water treatment brands and back our work with real parts and labour warranties. Our technicians take the time to walk you through your options, so you can make an informed decision with confidence not pressure.

Kelvin Mechanical serves communities across the Greater Toronto Area and beyond, with local technicians, 24/7 emergency support, and a continued investment in training and technology so every visit meets the same high standard.

We're also proud to support the communities we work in, because we believe comfortable, safe, efficient homes are the foundation of strong neighbourhoods.

Whatever your next heating, cooling, or water project looks like, Kelvin Mechanical is the team you can count on. Just call, and we're here to help.
