When I got my new house, I knew from past experiences that I wanted Capital City Heating & Cooling to help me with my HVAC system. I needed to replace a very old, rented hot water heater before I could move in and have the furnace serviced with some minor repairs. Their sales tech went out of his way to check the old system for me and they dealt with the furnace quickly with lots of info. They made a special effort to get the hot water heater I was buying from them installed as quickly as possible, including having to.put in new pipe to be up to code and returning the old rented hot water heater to its owners.
The staff are easy to communicate with, don't leave a mess, friendly & honest. The techs are knowledgeable and answer all your questions. They have good products and don't pressure you in to anything. They made what was a difficult problem very easy for me for a reasonable price. I highly recommend them to anyone in the Ottawa area for HVAC appliances & gas fireplace yearly maintenance too.

I had a great experience with my furnace cleaning. The technician, Kurt, was kind, informative, and very efficient. He took the time to explain what he was doing and answered my questions clearly, which I really appreciated. The work was completed quickly and thoroughly, and everything was left clean and in great shape. I would definitely recommend their service!

Technician arrived and was very friendly. Listened to concerns and quickly diagnosed the issue we had with our furnace. Explained everything during the repair process and provided us information on maintenance options. Great company and would definitely use them again.

I have been using Capital City since 2016 and I have been very pleased with their customer service and work. They are prompt, reliable, competitively priced and very professional. In addition to annual furnace cleaning, they have replaced a furnace and a water heater over the years and they completed the work quickly and cleaned up the area well and they left the area as they found it. I really like that they are a local Ottawa company and when I call, they respond quickly and arrange a service call. I am not transferred to a Toronto call center as I experienced in the past with another company.
