On one of the coldest days in February on a weekend my furnace stopped working. I called Hamco because they do yearly maintenance checks. Derek called me immediately to discuss the problem and within an hour he arrived. There was a problem with the pressure switch and he fixed it. That was a temporary fix until a new pressure switch was ordered and installed this week. Derek was a life saver that weekend. He is very professional and knowledgeable. He answered all my questions and was very patient. I would highly recommend Derek. Mary Lehto

We were lucky to have Cameron as our HAMCO furnace service tech in our home today. He is, in my opinion, an excellent example of a professional who knows how to properly & courteously conduct himself in a residential setting.Cameron called just ahead of his visit to let us know he was on the way, arriving within the allotted timeframe with all necessary tools, equipment & documentation required for this service, packaged in a polite & warm greeting at the door. He asked if it was ok to wear his boots downstairs while working; once ok'd he carried his boots in hand downstairs and then back up to the foyer once done. Upon completion Cameron presented a completed maintenance report which was legible, clear & easy to understand. He cleaned up the work area, leaving it as clean as he found it. He is welcome in our home any time.

Our furnace stopped working on a Saturday morning, and Derek came out and gave an honest assessment of the situation (22 year-old furnace, so it was not surprising it had given up the ghost), and on the following Monday morning we had a new Daikin furnace installed, which is working great! Great experience with the sales and installation staff. They even loaned us a few space heaters to get us through the weekend dealing with sub-zero temperatures! Will not hesitate to work with Hamco again!

We recently connected with Hamco to inspect our boiler. We discovered serious CO2 issues and required immediate support given the cold January weather. Najim gave us a quote for a new condo boiler/ water heater, providing a competitive quote and arranging for immediate installation. Adam F and Shamar arrived the next day to take care of the challenging installation. After 10 hours of effort they left us with a warm, spotless home. They were highly skilled, efficient and courteous. We are VERY impressed with the entire Hamco team and highly recommend them.

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
