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

This company was highly recommended but we are very disappointed.Substandard service was provided by to 2 inept technicians,First technician misdiagnosed the problem on our air-exchange system and ordered a costly part (control board). The new control board not only did not fix the problem but created a new problem.Second technician, who was to correct the problem free of charge, was unfamiliar with the system. After trouble shooting for approx. 2 hours unsuccessfully he ordered additional unnecessary parts and left disconnected wires and the control board exposed.After I enquired about an update, the dispatcher was going to schedule the technician to install the ordered parts at a cost of an additional $300.00 plus. This I refused andrequested to speak with the service manager and was promised a call back. That was over 2 weeks ago and I am still waiting.I refuse any further service from this company.Note: the actual problem was a faulty cable to one of the wall control switches.

Well I waited a while to write a review til it got "REAL cold". I have to say the HEAT PUMP/AC PUMP we had installed in the summer did an outstanding job dealing with the entire attic area with ease. It was so comfortable up there (when it was like 40+ degrees outside on those heat wave stretches we had here in old DUNDAS) we just wanted to be up there more often, also noticed the air was very comfortable and clear. Not too dry or humid, kinda just perfect.Our house was built in 1903, pretty typical Edwardian style, long, skinny and REALLY tall. Attic open from front to back of house.NOW that its COLD, prior to this HEAT PUMP install, our attic was an ice box. Tough to enjoy, NOT A PROBLEM NOW THOUGH !!! The heat in there is excellent!! It's just quietly keeping us at 24 degrees or so. The outside unit is so quiet I have to lean into it make sure we are running. Incredible really!! HYDRO bills do not show huge increases. I think we are quite similar in historical billing actually, be being more efficient in other areas. Ii.e. weekend laundry only (OFF PEAK), less fancy lights out back no one really looks at too much.The installer crew were in/out in about 7 hours. Great crew!!"ANDREW" was spectacular from start to finish with his knowledge, confidence and professionalism. I had 3 or 4 discussions with hvac folks, and clearly ANDREW knew the job better then the rest, so we signed with HAMCO!Thx folks, I've recommended you several times.B

Just had a ductless AC installed. Starting from the sales representative Andrew to the technicians who installed the unit, Ainslea, Shemar, Nick and Tony, we couldnt be happier with the service we received from start to finish. Professional, friendly and efficient, it was a pleasure having them in my home. Hard working bunch and will definitely be referring this company in the future. Thank you Hamco for the amazing job!
