We had a new furnace and A/C unit installed by Hamco 7 years ago. We get both units serviced annually by Hamco. The technicians have always been very friendly, courteous, and professional. This year, there was a leak in the water line leading to the humidifier on the furnace. Hamco advised me that this was not covered by the furnace warranty. Regardless, they agreed to fix the problem without charge. Derek was great and he fixed the problem quickly and efficiently.

HAMCO was able to schedule an install for my water heater within a week's time and the work was done very fast and they cleaned up well. I'm very happy to have had HAMCO replace the Reliance water heater rental in my house and I will be seeking their services in the future for other heating/cooling work if I need it. They were also very flexible about hanging on to the rental unit and returning it for me, which I appreciate very much.

We had Hamco supply and install a new residential boiler and indirect water heater at the end of September and could not be more pleased with the result. Jordan, the estimator, patiently explained our equipment options, provided references for work done in our neighbourhood, and responded promptly to further queries. The price he quoted was far below that of other firms. As residential jobs go, this was a large one and a crew of four was here for two long days getting it done. Under crew leader Justin’s management, the job went very well and any questions of ours were addressed immediately. Clean-up at the end of the job was well done and all scrap (two old boilers, a water heater tank, piping) was removed. Our home was left in excellent condition. With this review, we want to thank Hamco for a job well done, and wish to encourage potential customers to hire them. We would use them again without hesitation.

I've dealt with HAMCO for a few years now and I've always found their service to be honest and reliable. I recently had my tankless water heater de-scaled by Najim, one of their techs, and he was fantastic! He took his time, paid attention to detail, was clean and courteous. He even took a look at my furnace and made an adjustment for free! Highly recommend Najim and HAMCO overall. They might be on bit of the expensive side, but you get what you pay for really....

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

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.
