Najim was very knowledgable and he quickly diagnosed a serious problem with our furnace. He reinstalled the venting, put in a new motor and thermostat. He was very efficient, polite and our furnace is working perfectly again! I highly recommend HAMCO and technician Najim and will definitely call them for future service needs. Thanks!

Had Nolan come and install my new AC unit. Did a great job, showed me how everything works.

After replacing our furnace and installing a central air unit with Hamco we've had nothing but excellent, attentive service that is reasonably priced and achieved both on time and with great courtesy. Christian just performed the yearly maintenance on both units, and thanks to him we're all set for winter! There was an issue with a part he quickly and efficiently replaced, and I'm certainly happy to know it now instead of during the first cold snap.

There I was… with an rv hot water tank that needed to be replaced and some propane lines that were beyond sketchy. I didn’t know how to resolve these issues and who would take on such a project. I reached out to Hamco and although rv trailers are not something they usually tackle, they cared enough to listen. They understood I needed help and they took this job on. Right away, Nolan was out to do an on-site inspection to get a better understanding of what was involved and what needed to be done. He was so professional, personable and knowledgeable. He got right to the task at hand and understood quickly what needed to be addressed. A date was easily booked through the helpful and courteous office team. On June 12, 2024 Nolan returned and again, wasted no time diving in and getting the old hot water tank out and installing the new. Repairing the propane lines and testing and checking all the new system. I can’t thank Nolan, Jordan, Veronika and the rest of the team at Hamco enough for caring, going the extra mile and helping me out of a real jam. It’s not always easy for a service company to achieve the highest level of service that it’s customers expect… but Hamco sure did reach it here.

I have used Hamco service for 25+ years and have a Hamco installed furnace & air. I use their service for both spring & fall maintenance. They have been very helpful to the point of helping to keep my very old heating system as long as possible. Recently I had the spring maintenance service & there were a couple of problems after it was completed. I spoke to Tara who was very helpful & patient with my explanation of what was happening. A couple of days later Mike came to investigate the problems & quickly solved the problems & explained what was happening. They were both very helpful and considerate.

A great company to deal with!!! Tara helped direct me to the right person for ordering a hot water heater which was installed by Adam and Veronika. I have been a long time, happy customer.

We had our furnace, ventilator and some ducting replaced during a renovation of our condo - a major project. The team did a terrific job of removal and installation. The whole HAMCO experience was excellent, including the "back office": Cherryl in Accounting was super responsive throughout the process and is a really excellent rep for the company. Thanks, Cherryl. Let's hear it for Accounting!!

We at Martello Restaurant have been working with Hamco for several years and have nothing but the highest accolades for their services, including working with Jordan Vasilak who oversaw the installation of our HVAC systems, but also with Cherryl Skinner in their accounting group, who has always been professional and pleasant and kind in our interactions and communications. We highly recommend Hamco!

Earlier this week Hamco replaced my gas furnace and air conditioner with a new multi stage furnace and heat pump. The team was led by Shemar assisted by Nick, Veronika and Tony. They were courteous and efficient, and the work of removal and installation of the new system went smoothly. They did a great job of cleanup in the work area, and outside where the hear pump unit is located. Thanks to the installation team, and to Andrew who did the upfront work of finding the right solution for us.

Our old rental hot water heater burst, which left us with a bit of a flood and no hot water. We phoned around to the big box retailers to purchase and install a new hot water tank. The install dates were anything from 7 to 14 days wait. I phone Hamco, and they sent a rep that afternoon to estimate the job. The install was completed next day in 2 hours. Excellent service and competitive price. Highly recommend.

They misdiagnosed issue with my HVAC , it was just an issue with a valve but they mentioned it was issue with the board and valve. They ordered board from manufacturer which is very costly by itself and installed it in my unit , it got damaged in 2 weeks , they brought another board from manufacturer as new one they brought is in waranty. After this change my HVAC used to stop working abruptly and this happened multiple times over span of 3 months even after HAMCO's tech multiple visits. But when I contacted different contractor he was able to use the original board that came with my HVAC unit without any issues. It is running fine with original board now. Now I wanted to return the board they ordered but they wont take it or provide me a Purchase Order for that board. I called them multiple times requesting to return the board or provide me with PO but they did not provide it. They mentioned their service manager would call back to me but that did not happen.I see same reviews from other people as well
