I just want to commend Brett again for his dedication. What I just learned is that after service care is as important to Hy-Mark as getting the contract and doing what is prescribed work. I only wish that other companies would take your company’s lead when it comes to the care of its customers. I will have absolutely no problems recommending your company to anyone for work they need done. Maybe you can use what I have experienced with Brett with other employees and show that the impression he made on me was outstanding! Massimo, Guelph ON


We recently had Hy-Mark in to replace our conventional water heater from a competitor company, with a tankless one and we couldn’t be happier with the product and the service. Brett and his crew were friendly and efficient. At a time when when we felt good service seemed to be a thing of the past, Hy-Mark’s customer service was top notch. And if that wasn’t enough, it felt awesome to support a great local company. With a variety of products, services and incentives, definitely a company we will be doing business with again in the near future. Brad and Maria, Guelph ON


I have used Hy-Mark for a new air conditioner, furnace and water softener as well as small plumbing and repair problems. They are professional in all aspects of the job; they arrive when they say they will, find the problem, explain options and costs.  They are courteous and tidy. A five star company in my book. Karl, Guelph ON


I moved homes this summer after leaving my old home of 27 years. The process of dealing with a different furnace, AC, water heater and softener was daunting, as they were all managed by    different suppliers. I wanted one-stop shopping and management of this equipment, and Hy-Mark was able to  meet my needs. They ordered and installed everything that I needed with  efficiency and promptness. I now have peace of mind knowing that I have reputable people who will handle all of my heating and water needs with one phone call, 24/7. Thank you, Hy-mark.  Diane, Guelph ON


Wow, the Hy-Mark team did a great job with our recent installation. There was so much work to be done and they completed it on time in two days, without compromising quality of work. They clearly take great pride in the work they do and are happy to answer any questions about the product or best practices. Adam kept in touch with us from start to finish and went out of his way to ensure that we received all the possible rebates we were entitled to. Thank you to all for your professionalism and great communications. Marlene and Jim, Cambridge ON


When your heat goes down in the middle of February, knowing you have someone to call 24/7 makes a huge difference. Hy-Mark had our heat back on within the day. Tim, Owen Sound ON


Hy-Mark has been taking care of my heating & cooling for 6 years, the service is excellent. Call for an appointment, they are there on the dot.  The technicians are very professional. I would recommend them to anyone.  May, GuelphON


I had a unit installed by Hy-Mark on June 27, 2014. Their installation was very well done. It was clean and professional. I will definitely not hesitate to call them for future HVAC work that may be required.  Prajesh, Kitchener ON


Overall, great service. When the technician arrived on site, he quickly troubleshooted my issue and explained everything to me. He then went above the ‘call of duty’ to explain many other helpful details about my system. He was friendly and took my concerns seriously.  Jonathan, Guelph ON


Hy-Mark took personal interest in helping to solve some difficult installation issues. We could not simply replace our A/C in the same place. And with the change from freon to the newer refrigerant, we needed to change our piping too. Hy-Mark gave us better solutions than 6 other companies whom we had contacted. And, yes, we were given a very fair price.  Anonymous, Guelph ON


Very competitive prices compared to several other companies I received quotes from. Great customer service and installation was completed within a short time or receiving the initial quote. Travis, Cambridge ON
