The Oshawa, Ontario hvac contractors list has 33 businesses, 12 of them with a business email. Each record has the business name, phone, address, website and Google rating. One-time $9 USD — download Excel and CSV right after checkout, no subscription.
Five rows from the full 33-row dataset, sorted by rating & review count. The full file has one row per business with 16 columns: business name, email, email type (business or personal), phone, street address (with postal code), city, state/province, country, Google rating, review count, website, email quality, audit date, and any other emails and phones we found for the business with where we found them. The CSV adds email_2, email_3… where a business has more than one address. Service-area businesses (mobile mechanics, handymen, cleaners) deliberately don’t list an address on Google, so that column is blank for about 2% of rows.

Start with the rating — look for a hvac contractor holding 4.5 stars or higher with a healthy number of recent reviews, which signals consistent, current service. Confirm they're properly licensed and insured for the work you need, and read a few reviews to see how they handle problems, not just praise. The listings below are sorted by Google rating to make this easier.
