DeMark Home Ontario Granted with the Google Guarantee

The Google Guarantee certifies that professionals employed by a local business are licensed, pre-screened, and insured, allowing customers to quickly recognize a trusted service provider.

A Google Guarantee certified business is indicated by a green check mark “badge” underneath the names of qualifying companies.

What does it mean for a service provider to be Google Guaranteed?

For a business to be certified, Google performs an extensive inspection of all areas of the business through:

License verification

Google confirms that the company and its employees hold all the necessary licenses and certifications to be working in your home. DeMark Home Ontario is licensed by the Technical standards & safety authority (TSSA), the Electrical Safety Authority (ESA) as well as SaveOnEnergy, the Ontario Energy Board (OEB) and the Independent Electricity System Operator (IESO), Energy Star Canada Certified. We’re proud members of Natural Resources Canada / Government of Canada and the Heating, Refrigeration and Air conditioning Institute of Canada (HRAI).

Background checks

All employees of a certified business must have an extensive background check to ensure peace of mind for the customer and to mitigate all potential risks.

Insurance checks

This verifies that the company working in your home has the appropriate liability insurance coverage to protect you, your family, and your home. As a trusted HVAC service provider, we are an Enbridge participating company and all of our technicians are fully bonded and insured with full adherence to WSIB guidelines.

Positive customer feedback

Positive feedback from customers who previously hired the company is another component of the Google Guarantee certification. With many years of experience in the HVAC service, we have developed a positive track record in the industry which is proven by the satisfaction expressed by our clients in their reviews on Google, HomeStars, Houzz, TrustedPros, 411, etc.

How does Google Guarantee benefit me as a customer?

The Google Guarantee certification is intended to minimize consumer confusion by making it easier to find trusted service providers in your area by simply looking for the green Google Guarantee badge during your search. This new feature acts as a consumer protection service as customers know they have Google backing the quality of certified companies.
