How To Choose An HVAC Company

Know Your State’s Requirements For HVAC Contractors

Each state in Canada has specific guidelines regarding licensing, bonding, insurance, and continuing your education.

Know What You Need

Before you hire an HVAC company, check the system’s model and its maintenance history. You should also note the rooms that get uncomfortable, e.g. if it’s too hot or cold.

Ask For Referrals

Ask the people you trust for referrals and check if they can complete the job on time, within the budget, and are well-versed in the procedures.

Research Reviews

Although, price is more important when selecting a suitable HVAC company, reputation is important too. You can read reviews of the contractor on the website, Google, social media pages (such as Facebook), Yelp, and more. Some companies might not be perfect, but reviews will reveal the problems and how they can be addressed.


Ask For A Written Proposal

After you have chosen your HVAC contractor, ask the professional to give you a written proposal for you to review and sign before the work starts. A written proposal specifies the cost, job schedules, model numbers, warranty information, payment schedules, and other details that will protect you should a problem arise.
