    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 repair services in Thornhill, Ontario

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

In Thornhill, Ontario, AC repair pros should hold a valid HVAC licence and carry both liability insurance and workers' compensation coverage. This is especially important for any work involving refrigerants, which are regulated under federal law. Before committing to a pro, ask for proof of both, and don't skip this step just because the repair seems minor.

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

For most repair work in Thornhill, Ontario, a permit isn't required. However, if the repair involves replacing a major component like a compressor, or any work that touches refrigerant lines or electrical systems, some municipalities may require one. Your pro should know the local rules and flag this upfront if it applies to your job.

How do I know if my air conditioner needs a repair or full replacement?

A good rule of thumb is to weigh the cost of the repair against the age of your unit. If your system is more than 10 to 15 years old and the repair costs more than half the price of a new unit, replacement is often the better investment.

Recurring breakdowns, rising energy bills, and uneven cooling are all signs that your system may be nearing the end of its life. If you're unsure, post your job on HomeStars to get quotes from air conditioning pros in Thornhill, Ontario who can assess your system and help you make the call. You can also check out our guide to central air conditioner costs if you ultimately need a full replacement.

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

In most cases, yes. Air conditioning repair pros in Thornhill, Ontario are often HVAC contractors who are just as comfortable working on your heating system as your cooling one. If you need someone to handle both, [HVAC contractors in Thornhill, Ontario](https://www.homestars.com/heating/hvac-contractor-pros/Thornhill, Ontario) on HomeStars are a good place to start, as many pros offer full heating and cooling services under one roof.

You can also take a look at our guide to heating and cooling costs to get a sense of what a combined project might run you.

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

For most repair calls in Thornhill, Ontario, there isn't much to clean up, but a good pro should leave your space the way they found it. If a major component is being replaced, confirm upfront whether old parts and packaging are included in the removal or if there's an additional disposal fee.
