How can we help you?

Grand Valley is a quiet, friendly place to live in Dufferin County. Perched along the mighty Grand River and comprising more than 100 local farms, the Grand Valley area has been called Nature's Playground. Don's Heating & Cooling has proudly provided residential and commercial customers in this area with high-quality HVAC products and reliable services for over 30 years. Contact us today for all your heating and cooling needs.


Newer high efficiency air conditioners are sealed systems with self-lubricating components so no maintenance or service is required for functional systems.

Older standard efficiency systems (15 years +) are very inefficient systems that leak o-zone depleting refrigerant into the atmosphere. These systems should be replaced instead of “bandaged” to ensure cost efficient, safe and environmentally sound operation.

Speak with one of our qualified Home Comfort Advisors and take advantage of our special offers to save money while keeping your family comfortable in all seasons.
