  • Furnace Installation Specialist in Markham

    I'm Cole Ginsberg, the owner of CFG Mechanical here in the GTA. I've been in the trades over ten years and I'm a fully certified plumber. I didn't plan on this path either, I started in construction doing landscaping and general contracting before plumbing found me and stuck. I sunk my teeth in low-rise residential, where you learn the most. You're in someone's home, things need to work right the first time. From there I moved into ICI work, running crews as a foreman on large commercial jobs, then spent a few years in high-rise construction handling mechanical systems most residential guys never touch. That's the background CFG Mechanical is built on. What sets me apart: I'm licensed and certified in both plumbing and mechanical — gas, boiler, hydronics, heating, venting, cooling. So you're not calling two companies and hoping they talk to each other. One call handles it. I cover 24/7 emergency service, HVAC, heating and cooling, gas work, indoor air quality, ductwork, thermostats, water heaters, plumbing, and hydronic heating including boilers and radiant systems — across residential, commercial, and multi-residential properties. Licensed. Certified. Built to be the one call that actually does it all.

FAQ: Questions about furnace installation and replacement in Markham

How long does a furnace installation in Markham take?

Most furnace installations in Markham take between four and eight hours, depending on the complexity of the job. If additional work is required, such as ductwork modifications or new venting, the project may take longer.

How do I know if I need a new furnace or just a repair?

In Markham, as a general rule, if your furnace is over 15 years old and repair costs exceed 50% of the price of a new unit, replacement is usually the more cost-effective choice. Frequent breakdowns, rising energy bills, and uneven heating are also signs it may be time to replace.

What size furnace do I need for my Markham home?

Furnace sizing is based on your home's square footage, insulation, ceiling height, and climate zone, and is measured in BTUs (British Thermal Units).

An undersized furnace will struggle to heat your home, while an oversized one will cycle on and off frequently, wasting energy and causing unnecessary wear. A furnace installation pro in Markham can perform a proper load calculation to determine the right fit for your home.

What is AFUE and why does it matter?

AFUE stands for Annual Fuel Utilization Efficiency, and it measures how efficiently a furnace converts fuel into heat. A furnace with a 95% AFUE rating converts 95% of its fuel into usable heat, with only 5% lost.

The higher the AFUE rating, the lower your long-term energy costs, though higher-efficiency units typically come with a higher upfront price. If you need help choosing a unit with a high AFUE rating, HomeStars can help you find furnace installation specialists in Markham who can advise.

Are there rebates or incentives available for furnace replacement in Markham?

Yes, several programs exist to help offset the cost of a new high-efficiency furnace, including utility rebates from local providers and provincial programs available in most parts of the country.

Eligibility and amounts vary by province and the type of equipment installed, so it's worth checking what's available in your area before purchasing. Post your project on HomeStars to connect with furnace installation pros in Markham who can help you navigate available rebates.
