My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.

Colair Air Duct Cleaning
A/C Repair & HVAC Contractors in Ottawa
Average rating: 5 out of 5 starsJuly 7, 2016
“Colair did my older house in Manotick and I was surprised by how much I really needed the job done! I dealt with the owner who was knowledgeable and responsive. The job was really thorough and I am happy with the results. Best of all the price was the best out of the 3 quotes I got! I would highly recommend. Sue”
Robidoux Heating & Air Conditioning
A/C Repair & HVAC Contractors in Ottawa
Average rating: 5 out of 5 starsApril 16, 2018
“Purchased a condo and had no idea the last time my Islandaire unit was cleaned. Phillip gave me an estimated amount which included taking it apart and doing a proper thorough cleaning (not just vacuuming). When he arrived I might add on the worse winter day of April on time!. I was already impressed BUT than he looked at the unit and confirmed that it was not ready to be cleaned. SAVED me $$$$$$. Did not charge for his assessment. I will not only use him in the future but will gladly refer him to everyone in this condo and who hopefully is reading this review!! I hope he remains in business for a long time as, this day and age you do not find a business man with this kind of honest integrity! Gold STAR service. P.S he was highly recommended by Islandaire located in the states and the superintendent in the building.”

What do HVAC contractors do? HVAC stands for heating, ventilation and air conditioning. An HVAC technician or contractor specializes in heating systems, air duct cleaning and repairs, insulation and air conditioning for your Ottawa, ON home and other homes.

When should you hire local HVAC companies?


Generally, Ottawa HVAC contractors or HVAC installers work with or run companies that repair or install heating systems and a/c services for homes.

Local air conditioning companies can help with a wide variety of air conditioning services, including both a/c installation and a/c repair. Air conditioning contractors, also known as a/c contractors, get extremely busy in the summer when temperatures are highest. For larger jobs, like installation, you might want to hire a/c installers during the off season like spring or fall. You should also try to do the same for heating services. Heating installers and heating contractors might be more available in the summer or fall for larger projects.

Ask HVAC contractors about these residential heating and cooling technologies:


  • Tankless hot-water pumps
  • Residential air cleaning devices
  • Ductless air circulation systems
  • A desiccant enhanced evaporative air conditioner system (for hot and humid climates)
  • Heat recovery systems (which cool the air and heat water with no extra energy use)

Find HVAC contractors, heating companies and air conditioning installers on Houzz. Look in the Professionals section of our website and search for Ontario HVAC contractors. Read reviews and see how an HVAC contractor might approach your Ottawa, ON home’s heating and cooling challenges.
