What a Verified badge means

Before a business gets a Verified badge, we:

  1. Look it up online: its website, its public reviews, good and bad, and anything that should worry a customer.
  2. Email the address on the listing with a one-time link, and the business approves its listing or asks us to remove it.

Each Verified listing shows when it was last checked. We do not check insurance or licences, audit accounts or inspect work, and we do not guarantee any job, so please ask any business for its certificate of insurance before you hire. Read the full process.

About hvac contractors in Markham

Heating, ventilation and air conditioning contractors in Markham typically handle furnace and boiler installation, central air conditioning, heat pumps, ductwork, and seasonal maintenance, along with repairs when systems fail during a cold snap or a heat wave. Because Markham sits in York Region, north of Toronto, many homes and businesses here rely on these systems year-round. Before you agree to any work, ask for a written quote, examples of similar recent jobs, and a realistic timescale for completion. Comparing two or three written quotes side by side makes it easier to spot gaps in scope and to choose with confidence.
