    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: Common questions about air conditioning installation services in Thornhill, Ontario

Are air conditioning installation pros in Thornhill, Ontario insured and licensed?

In most cases, any form of HVAC work requires a licensed technician, particularly for tasks involving refrigerants, which are regulated under federal law.

Any AC installation pro you hire in Thornhill, Ontario should carry both liability insurance and workers' compensation coverage to protect you in the event of accidental damage or injury on the job. When getting quotes, don't hesitate to ask for proof of both before work begins.

Do air conditioning installation pros in Thornhill, Ontario need a permit?

In most cases, yes. Air conditioning installation in Thornhill, Ontario typically requires a permit, particularly for new installations or major system replacements. However, for window units and other single-room setups, permits aren’t needed.

Your contractor should be familiar with local requirements and in many cases will pull the permit on your behalf. If a pro suggests skipping the permit, that's a red flag as unpermitted work can cause issues with your home insurance and resale value down the line.

Does a new air conditioner installed in Thornhill, Ontario come with a warranty?

Most new AC units come with a manufacturer's warranty covering parts, typically ranging from 5 to 10 years depending on the brand and model. Labour warranties are separate and vary by contractor, so it's worth confirming what's covered and for how long before signing anything.

Registering your unit promptly after installation is usually required to activate the full warranty. To find AC installation pros in Thornhill, Ontario who stand behind their work, browse ratings and reviews on HomeStars before making your decision.

How long does air conditioning installation take in Thornhill, Ontario?

For a straightforward central AC replacement in Thornhill, Ontario, most installations can be completed in a single day. New installations that require ductwork or electrical upgrades will take longer, sometimes two to three days or more depending on the scope of work.

Your contractor should be able to give you a clear timeline as part of their quote.

Can an air conditioning installation pro in Thornhill, Ontario also handle my heating needs?

In many cases, yes. Many air conditioning pros in Thornhill, Ontario are HVAC contractors who work on both cooling and heating systems. If you're looking for someone to handle both, searching for HVAC contractors near you on HomeStars is a good place to start, as many pros offer full heating and cooling services under one roof.

You can also check out our guide to heating and cooling costs to get an idea of what a full HVAC project might cost you.

Do air conditioning installation pros in Thornhill, Ontario handle cleanup after the job?

Most pros will remove and dispose of your old unit and tidy up the work area once the job is done, but it's worth confirming this upfront. If you're having a full system installed for the first time in Thornhill, Ontario, ask specifically about disposal fees as some contractors charge extra for hauling away old equipment or packaging materials.
