“This is the second time we used Hy-Mark’s services. Need to run a heat vent to our new family room and an office room in the basement. Jason was great very detailed, gave me couple of options and done a great job. We are really happy with the outcome and will use Hy-Mark for future.”

“The installers took pride in workmanship, nice neat job. Would highly recommend Hy-Mark for any heating, a/c or plumbing home comfort needs. Pleasure to work with.”

“Excellent, efficient, and friendly service. Brett was always available to address issues and answer questions. Having dug a six-foot trench through our beautiful garden, they restored the ground to a point where we could do the gardening with a minimum of grief.”

“I contacted Hy-Mark to make arrangements for my Oakville home furnace and pool heater to be serviced as I was putting the property on the market. A technician arrived on time completed both jobs and gave me a complete written and verbal update. This involved purchasing a specific item from a local pool shop to complete the job to avoid having to return. Excellent service, 100% I will have no hesitation recommending or using them again.”

“Put in a new ac unit and we rented a hot water heater from them. Everyone was great to deal with. Job took longer than they expected but they came back quickly and got it finished. A very neat and tidy job and professional group.”

“The Hy-Mark team recently installed a new furnace, air conditioner, air cleaner, humidifier, tank less water heater and water softener. It was a lot and they had to correct many items to bring everything up to current code and standards. They managed to all of it in two days and the quality of their work was not compromised. Adam did a great job of educating us on the available products and kept us abreast of any new rebates as they became available. We really appreciate the open communications, information sharing and honesty. Thank you Hy-Mark.”
