At Riverflow HVAC Inc., we specialize in licensed gas furnace services for homeowners and light commercial clients across the Greater Toronto Area — including Toronto, North York, Vaughan, Markham, Richmond Hill, and Scarborough. Whether it’s a mid-winter breakdown or a planned upgrade, you can count on prompt response, skilled workmanship, and fully code-compliant installations — all completed by a licensed gas technician who takes your comfort personally.

Gas Furnace Installation & Replacement

We install high-efficiency natural gas furnaces that deliver dependable heat while helping reduce energy costs. Whether you’re replacing an older unit or outfitting a brand-new build, we’ll ensure your furnace is properly sized, safely connected, and optimized for long-term performance. For seasonal cottages and rural properties without natural gas service, we also provide propane furnace installations with the same focus on safety, efficiency, and comfort.

Gas Furnace Repairs

No heat? Strange noises? Uneven performance? We provide fast, accurate diagnosis and repair for all makes and models of natural gas and propane furnaces. Common issues include ignition failures, blower motor problems, faulty sensors, and dirty burners — all of which can reduce efficiency or create safety risks if left unchecked. Every repair is handled with care by a licensed gas technician who arrives ready to troubleshoot, explain the issue clearly, and restore safe, efficient heating. Our goal is to minimize downtime, extend the life of your system, and ensure your home stays comfortable no matter how cold it gets outside.

Furnace Maintenance

Annual maintenance keeps your heating system running efficiently, extends its lifespan, and helps prevent costly mid-winter breakdowns. Our service includes a full system inspection, filter replacement, combustion testing, and cleaning of essential components. Ask about seasonal tune-ups to keep your furnace operating at its best.

Thermostat Installation & Upgrades

We install and replace all types of thermostats — including programmable, Wi-Fi, and smart models like Nest and ecobee. A properly installed and configured thermostat ensures maximum comfort, control, and energy savings.

Emergency & Same-Day Heating Support

When your furnace stops working, every hour counts. We provide fast, responsive service for urgent heating issues — including no-heat calls and furnace shutdowns. Your repair will be prioritized to restore comfort as quickly and safely as possible.
