Best Heating & Air Conditioning / HVAC In Ottawa

“Call Francis fuels today looked at my Furnace. I joined there monthly plan for care for furnaces and other appliances. Saved me quite a bit of money today. Thank you for being quick and efficient. Highly recommended.“

“Great service, excellent price, no-pressure sales.
Recently had to replace old hot water heater. Checked with a number of different companies and priced out purchase and rental options. RM responded to correspondence very quickly, and their no-pressure sales was greatly appreciated. They presented pricing options simply and plainly. They also replaced our furnace almost 10 years ago and there have been zero issues in that time. Professional, respectful, efficient with time.

Update July 2026: One of the thousands of households that were flooded in Canada Day storm, so the furnace installed by Rick Menard had to be replaced due to water damage.

Still great service, no upsell pressure, ample options presented. The gentlemen who did the install were prompt, courteous, knowledgeable, and friendly. Did a furnace and hot water heater much more quickly than I thought was possible. I recommend them to everyone I know who needs heating/cooling solutions.“

“Excellent service. Pierre goes out of his way in providing efficient service. Highly recommended“

“david ngalle was very helpfull and efficient. It would be helpful if your servicemen had hoses as many of us that live in condos do not use hoses outside since the corporation takes care of the exterior.“

“Mark Clatney was the technician who came out to inspect my leaking water heater. He went above and beyond to help me. He tried everything he could to resolve the problem then and there. I am very appreciative of his professionalism.“

“Ryan and Rob were excellent technicians when they came to install our new heat pump/AC and furnace. They were prompt, professional and answered any questions. After install they did final walk around/check with us. Overall, very impressed with them both. Highly recommend.“

“Dong was very professional, prompt, and thorough. He communicated beforehand when he would be arriving and advised that I needed to replace the humidifier filter and told me which one I needed to purchase. He replaced the furnace filter as I had one available.“

“This was my first and only call for help getting the AC running again. I thought I was going to be running the gauntlet of researching and calling multiple companies and instead Scott Home Comfort popped up as a local provider and had me sorted out in no time and with excellent service. Thank you!“

“Always a pleasure working with Capital City. The owners, the customer service, the scheduling, the salespeople, they're all fantastic and really seem to care about the product and your comfort as a customer. No unnecessary upselling either. They are worth paying more money to use because of how good they are -- the beauty is you don't even have to pay more (in fact you pay less), because they've consistently been the lowest price point for me after getting quotes around town. Use them without hestitation.“

“I really love our new air conditioning. Installers Gord and Sean worked all day. Nine hours. Also shout outs to Derek Mcguaig and Paul for helping us to get the quiet and process started. Thanks again“

“Great service from these guys. After the Canada Day floods they were able to inspect my furnace on Friday and fix it on Tuesday. I've purchased my last two HVAC units from these guys and if I have to buy another, I'm going with them.“

“Our technician, Eric, was prompt, courteous and professional! For the past six years once they installed our AC and furnace, the service has always been excellent!“

“I was extremely happy with the professional work that was completed with the installation of my heat pump, furnace and waterless tank. The 2 gentlemen even found a potential fire hazard in the fire panel that was not found during my home inspection in Dec 2025 and fixed it.“

“Matt has been taking care of our furnace and air conditioning for many years, and once again he provided outstanding service today. He took the time to carefully explain the issue, answered all of our questions, and never made us feel rushed. He thoroughly cleaned and washed our air conditioner, and everything was left spotless when he finished.

As landlords, whenever one of our tenants has a heating or air conditioning issue, Matt always does his best to come as quickly as possible. His prompt response and reliability give us great peace of mind, and we know we can count on him when it’s needed most.

It’s rare to find someone who is so knowledgeable, honest, professional, and genuinely cares about his customers. We truly appreciate his attention to detail and excellent customer service. I highly recommend Matt to anyone looking for reliable HVAC maintenance and repairs!“

“I had a furnace emergency during the winter and they did an excellent job. They replied during the weekend, they were fast and professional“

“We purchased a gas pool heater from Pure Water a few years ago, and when it recently started shutting off with a “service system” error, we reached out for help. Pure Water highly recommended Mike from RM Contracting—and we’re so glad they did.
I emailed Mike about the issue, and he responded within 10 minutes with a troubleshooting suggestion that solved the problem. His responsiveness and expertise were truly impressive.
What stood out most was his honesty and integrity. He easily could have charged us for a service call, but instead chose to help us fix the issue remotely at no cost.
Exceptional service, knowledgeable, and trustworthy—highly recommend Mike from RM Contracting!
Thank you!

“We called for a blocked drain and received courteous and professional service for the next day. The technician was very diligent with his work and left our bathroom clean and the drain unclogged. We would strongly recommend this company!“

“Small Ottawa base company with extremely professional and friendly technicians. The work was done well and efficiently. Very happy with our new AC and would recommend these guys to anyone looking for HVAC services!“

“I’ve been loyal Top Hat client for years and have referred many people to use their services. This week I upgraded my single head mini-split vac (ductless AC) to a new, more powerful 3-head system AC/heat pump. Everyone from Sales (Doug), to office (Richard ), to the installation technicians team (Darryl and team, and supervisor, Jonathan) —were absolutely excellent. Respectful, friendly, technically skilled — and helpful (moved and put back a couple of heavy items I was unable to lift), and they did a good clean up job inside and out. You will still need to do a bit of vacuum and dust due to light debris / sawdust, but if that bothers you — you’re being unreasonable). I am very happy with my new system so far for cooling and look forward to using the heat function as a complement to my electric baseboard heating during the winter months. Thanks team! You’re very appreciated!“

“Chris did a great job. We can now enjoy our living without worrying if we will have hot water the next day. Thank you LG Home Comfort“

“Got the job done quickly and efficiently and provided great customer service. Thanks Gagan & Joey!“

“I highly recomend this company , Andrew gave me a estimate an explained what i need, Shawn an Aaron the two techs were very professional an did excellent job . If in need of HVAC service there is no better service or price . ThankYou“

“Ercans was referred to us by a friend and it was the best thing that happened to us. Oz came by to look at our furnace that was red tagged and he recommended a replacement at a very good price and we decided to go ahead with it after getting two other quotes. What a good choice. I highly recommend them for all your heating and cooling.“
