Our History

William Edward Holmes first established Holmes Heating Inc. in 1962, building the business on the belief that our customers deserve to be treated with the highest degree of integrity and receive quality heating, cooling, and indoor air quality products and services at the most affordable prices.

We still hold dear these values of integrity, reliability, and affordability today. Holmes Heating offers the same commitment to quality service and workmanship, which has enabled us to become one of the largest and best known HVAC sales and service providers in Ottawa – a proud business serving more than 25,000 homes in the National Capital Region, from Almonte to Orleans and Kanata to Carleton Place.

GrowthAlways Growing and Expanding

Our company continues to grow to serve our customers in new and better ways. Today, our customers have access to a broad suite of essential home comfort products and services. In 2000, we established a new air quality division featuring a wide range of cleaners, filters, humidifiers, and ventilators.

We now also install whole house humidifiers and ventilation systems, and provide duct cleaning services and indoor air quality assessments.
