We have an older boiler furnace and I know it's in good hands with Joel and Cam. Joel is so knowledgeable about the furnace and the two of them worked tirelessly at a recent long needed cleaning appointment. Joel and Cam are incredibly respectful and a pleasure to deal with.

We had an excellent experience working with HamCo for our new heat pump installation. From the very beginning, Andrew guided us through every step of the process — from choosing the right unit for our home (we went with a Daikin heat pump/furnace combo) to walking us through budget details and keeping everything honest and transparent. When we decided to also add a hot water heat pump, Andrew made that seamless too.He was incredible with the paperwork for the Ontario government rebates, making sure we had everything in order for both the heat pump and water heater. The installation itself was smooth and even finished a full day ahead of schedule. The team removed and returned our rental hot water heater, handled the refund process for us, and kept the house spotless throughout. Every installer we met was polite, professional, and clearly knew their stuff.It’s been about a month since the install, and everything looks fantastic and is working beautifully. We couldn’t be happier with the results and highly recommend HamCo to anyone considering a heat pump.

Veronica and Shamar did a superb job for us installing a Daiken ductless heatpump in our 14th floor condo. They laid out drop sheets and were in and out in less time than we anticipated. We had two issues with the installation as they were working and Veronica made on the fly adjustments which made things perfect for us. Best of all the unit runs quietly and is keeping us c-o-o-l. Thanks. Shelly and Ray

We can't say enough good things about our experience with Hamco. Andrew was so great to deal with and checked in about our satisfaction regularly. Najim and his team worked so hard and efficiently to get our gas fireplace installed and also to put a new vent in our chimney. He communicated well and checked in regularly to make sure we were happy with his work. Varonika was also very helpful in problem solving and coming up with solutions for us to make our fireplace looked way better. Her attention to detail was very impressive.We experienced a massive flood last July and have had many workers into our home. Hamco has been the most professional, efficient and kind.

I called Hamco to learn more about a humidifier for my furnace. Hamco installed two HVAC systems in my home over the past many years...great service and price...no need to shop around. Tech Najim installed the humidifier this afternoon. Enjoyed speaking with him as he worked. He explained what he was doing, answered my questions professionally. Neat work and cleanup. I highly recommend Hamco staff who responded to my questions and Tech Najim who installed the product. Thank you.

We were recently faced with our 17-year-old furnace breaking down and beyond repair. Despite the extremely cold weather that resulted in a larger number of service needs for Hamco, Najim met with us in just over 24 hours, spent time accessing and explaining the situation and offering the best options for the needed replacement. He worked to get us up and running quickly with a Saturday install and left us with a space heater to ease discomfort overnight. He was personable, knowledgeable and took time to ensure we were happy with the decision we made. It wasn't an expense we had planned for but Najim eased the situation with his excellent customer service. He was happy to answer any questions we had and worked to ensure we got the best price and service possible. Veronika and Shemar arrived early the next day to replace our furnace with a new Daikin. They were also personable, professional and efficient. We feel fortunate to have Hamco to count on with HVAC needs. They have a great team of people who also seem to greatly appreciate how they are respected and treated by the company. It's wonderful to have a local family-owned business providing excellent service. We've been with Hamco (initial installs and service plans) for 17 years and plan to continue with them as needs arise.

Our furnace died on us on one of the coldest nights of the year at the start of the christmas holidays. We immediately started looking around for a new furnace and settled on Hamco for a few reasons. First off the original furnace which had lasted 50 years was installed by them and with that track record they seemed like a good choice. 2nd Jim the sales person was great at understanding what we needed, helping us figure out what furnace was the best fit for our needs and even provided us with an extra heater till the new furnace was installed. 3rd The install team of Josh and Nick got the job done efficiently and explained everything to us. The furnace was working that day and was much more efficient then our old furnace.
