About Us

At Coulson Heating, we have been serving southern Ontario for more than twenty-five years with our main focus being on installing heating and cooling systems for new home construction. The company was established outside of Alliston Ontario in 1990 by Jeff and Janice Coulson. Over the years we have been serving many of the same builders and value the professional relationships that have been formed and maintained. The small town beginnings of the company show in the care and attention to detail provided in all aspects of our work.

Many of Coulson Heating’s certified residential heating Journeymen have been with the company for upwards of fifteen years. They are now working with the younger generation of apprentices, including the third generation of the Coulson family. This allows Coulson Heating to continue to have a skilled and efficient crew for every job.

The company is expanding into new areas of service such as furnace retrofits, duct cleaning, and other needs for the home. We are offering these new services to help our existing customers as well as new clients through the referral process. The company’s growth has not lessened the personal small town touch of Jeff and Janice as they are still active in the day to day operation both in the field and in the office.
