This is a very fine company. Staff is their biggest asset, always prompt, polite and professional. Service excellent. High personal values too. When I was looking to get a new furnace eight years ago, a friend referred me to Ottawa HVAC, so glad I called. I highly recommend this company

We recently had our furnace replaced by the team at Ottawa HVAC. Everything about the transaction was flawless. Exceptional service, reliable product, professional workers, and no hidden fees. Install was detailed and clean. Highly recommend this company for any/all your heating and air conditioning needs. Thank you!

From my first discussion with Jim to go over the specs and pricing of my new furnace and AC to the install with Nathan and Marc right until the final paperwork and payment with Alannah, I was impressed with the friendly and professional service I received. The Techs were very careful not to damage the flooring and walls when removing the old equipment and installing the new. This is a local company that you can count on for great service. I look forward to dealing with them for years to come.

A business that’s based on ethic and customer service. No pressure to buy and actually made every effort so we wouldn’t have to. When we decided to install a new system, the technicians that arrived we so professional and diligent. An excellent experience from beginning to end.

I am highly satisfied with my experience of having a new furnace installed. A very smooth process from the sit down with Jim to get a quotation all the way through to the installation. I highly recommend you contact Ottawa HVAC for a furnace quote

This company prides itself on Quality from top to Bottom. All I can say is I wish there was some way I could express just how incredible I was treated Staff from President to Technician are amazing.

I was thoroughly impressed with the professionalism and timely responses I received over the holidays from Mr. West and the remainder of the HVAC crew. Their dedication to providing a high standard of customer care was evident throughout. I would highly recommend for any and all HVAC related needs.

In and out in a timely matter. Both techs were courteous and respectful of our home. Venting issue that had been overlooked many times by the last HVAC companies that came to perform our original furnace annual service was spotted quickly and corrected on a follow-up visit by Samuel about 1 week later at no additional charges. Shows that Jim's team cares about their customers health, safety and well-being. 5 stars to all 3 techs and coop that came to our house! Thank you.
