• I highly recommend NKR HVAC for gas installation services. They recently installed a new gas line for my gas range, and the entire experience was seamless. Because they are TSSA certified, I had absolute peace of mind knowing the work was being done safely and strictly to code. They handled all the necessary paperwork efficiently, providing both the required gas permit and the official gas tag upon completion. The technicians were professional, punctual, and left the workspace spotless. If you want a company that takes safety and proper certification seriously, look no further than NKR HVAC!

• After a highly stressful basement flood that completely ruined my furnace and AC, this company was an absolute lifesaver. They responded incredibly fast and handled the complete HVAC replacement with total professionalism. Dealing with water-damaged equipment is a nightmare, but they were meticulous, ensuring every single aspect of the new installation was completely up to code with zero shortcuts taken. They took the time to patiently answer all my questions and thoroughly explain how the new system operates. Everything is running flawlessly. Five stars!

They didn't cut a single corner, everything was installed perfectly to code. I asked a lot of questions, and the technicians patiently explained every detail of the new system so I felt completely comfortable with the operation. Everything is working wonderfully now, and they even left the workspace spotless. I highly recommend them to anyone in Ottawa needing reliable heating or cooling work! Thank you Hisham, Jihad and Mohsen!! 🙏

• I hired NKR HVAC for gas hookup and dishwasher installation and they were above and beyond as they exceeded my expectations. Excellent quality service, very professional, and hassle free. I highly recommend hiring them for any job you have.

  Mohanad B.★★★★★

• I had an A/C emergency this past weekend, and I'm so grateful for the excellent service from NKR HVAC. They responded quickly and had my A/C diagnosed and repaired within just two hours. The technician in charge was incredibly knowledgeable, professional, and friendly. He had also repaired my fireplace last winter, so I was happy to see him again. It's rare to find someone so skilled and reliable. What impressed me even more was the fair and reasonable pricing. You don't have to pay an arm and a leg to get quality service. Thank you, NKR HVAC, for your outstanding service. I highly recommend you to anyone looking for honest, reliable, and professional HVAC service!

  Saadi S.★★★★★

• We got our BBQ Friday night and realized we didn’t have the proper pieces to install it to our gas line. We called NRK Saturday morning and he came as soon as he could. He installed it quickly and efficiently. He was professional, knowledgeable and gave us safety tips. We 100% recommend his services. Thank you NRK!!!!!

  Rawan H.★★★★★

• He was very quick in response and very helpful throughout the process. Highly recommended

  raunak P.★★★★★

• I’ve dealt with a lot of contractors over the years, and Hashim is one of the few I’d recommend without hesitation. He’s honest, easy to deal with, and actually takes the time to explain what’s going on instead of trying to sell you things you don’t need. His pricing was fair, his workmanship was excellent, and he stands behind what he does. Any time we’ve needed him, he’s been quick to respond and always made us feel like a priority. It’s hard to find someone this reliable these days. If you’re looking for an HVAC company you can trust, give Hashim at NKR HVAC a call. You won’t be disappointed.

  Tony L.★★★★★

• If you’re looking for an HVAC company you can truly rely on, I can’t recommend NKR HVAC enough. Hashim has honestly been our saviour. When we first contacted him about issues with the A/C unit at our home, he responded incredibly quickly. He provided us with a fair and honest quote, and after comparing it with several other companies that gave us outrageously inflated prices, choosing NKR HVAC was an easy decision. Within just a few days of our initial call, Hashim and his team had our brand new A/C unit installed. From start to finish, they were professional, thorough, and paid incredible attention to detail. Hashim took the time to answer every question we had, explained everything clearly, and never made us feel rushed. He also stands behind his work with an excellent warranty, which gave us even more confidence in our decision. Then, about 2–3 months later, we experienced an issue with the A/C unit at one of our rental properties. Once again, Hashim went above and beyond. Even though it was later in the evening, he prioritized our call and came out that same night to inspect the unit. Thankfully, he was able to diagnose and repair the issue on the spot—which was a huge relief considering it happened during one of the hottest days of the summer. What really sets Hashim apart is that he doesn’t just fix the immediate problem. He took the extra time to inspect for any other potential issues that could have contributed to it and even referred us to the appropriate companies for work outside his scope. That level of care and honesty is hard to find these days. Reliable, knowledgeable, responsive, honest, and genuinely cares about his customers. Hashim has earned our trust, and NKR HVAC will always be our first call. We wouldn’t hesitate to recommend him to anyone looking for exceptional HVAC service.

  K B.★★★★★

• Another company quoted me $5,000 to replace my air conditioner, claiming it couldn’t be repaired. I decided to get a second opinion, and I’m so glad I did. This company diagnosed the problem correctly and repaired my AC instead of replacing it, saving me $5,000. They were honest, knowledgeable, and didn’t try to sell me something I didn’t need.

  Momo★★★★★

• Excellent service! We are extremely satisfied with the installation of our air conditioner. The team did an outstanding job with great professionalism and attention to detail. The owner is very attentive, takes the time to listen to customers, and provides valuable advice. We found their prices to be among the best in Ottawa, while delivering top-quality workmanship. We highly recommend this company to anyone looking for reliable, professional service at a great price. Thank you for the excellent work!

  chakib M.★★★★★

• I hired NKR HVAC for furnance maintenance and had an excellent experience with the service.

  Nick★★★★★

• I recently hired NKR HVAC on May 14, 2026, to disconnect my old humidifier and install a new whole-house humidifier, and I couldn't be more impressed with the service I received from Hisham. From the moment I contacted him, Hisham stood out for his responsiveness and professionalism. He returned my call promptly, arrived as scheduled, and took the time to thoroughly explain every aspect of the installation process. What impressed me most, by far, was his patience and attention to detail. No matter how many questions I had, he answered each one thoughtfully and never made me feel rushed. He was genuinely committed to making sure I understood the work being done and felt confident with my new system. The installation itself was completed with exceptional skill and care. Hisham disconnected my old humidifier, installed the new unit, connected the wiring and humidistat to the heating circuit, connected the water supply, installed the new ductwork and drain hose, and thoroughly tested the humidifier to ensure everything was functioning perfectly. His workmanship was meticulous, and it was clear that he takes great pride in doing things the right way. What truly sets Hisham apart is his conscientiousness and willingness to go above and beyond. He didn't simply complete the job and leave—he stayed until every question and concern had been fully addressed. His dedication to customer service, attention to detail, and genuine desire to help were evident throughout the entire experience. It's rare to find someone who combines technical expertise with such outstanding professionalism and care for their customers. Hisham is an incredibly knowledgeable, responsive, and trustworthy professional, and I would not hesitate to recommend him to anyone needing HVAC services. NKR HVAC is fortunate to have him, and I cannot recommend him highly enough!
