Are air conditioning installation pros in Markham 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 Markham 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 Markham need a permit?

In most cases, yes. Air conditioning installation in Markham 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 Markham 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.
