Update: We just had our annual maintenance done and as usual, the booking and service were done efficiently and professionally. Cameron was pleasant and before servicing the... furnace and AC he was happy to answer a couple questions I had. Pleased once again with Hamco's service.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.read more

Honest, expert advice! I asked HAMCO about adding a HEPA filter and UV light to my gas forced air furnace. Instead of selling me an expensive, unnecessary installation,... Andrew honestly advised that portable units would suit my needs much better. That level of integrity is rare. They truly care about the client over making a quick profit. Highly recommend!read more

I've been dealing with Hamco now for 26 years - on my 3rd house and have only had good experiences with Hamco. An example of how their staff go above and beyond is during the... installation of my furnace in 2006, my elderly neighbour complained about the wasps flying around her house. The furnace installers noticed where they were going in and resolved the problem.I get the air-conditioner checked annually and the technicians are always professional and knowledgeable. A special shout-out to Cameron who looked after the inspection today and explained the readings today.I would, without reservation, recommend Hamco to anyone needing heating and cooling equipment.read more

After doing a significant amount of research I contracted with HAMCO to install a heat pump to replace my aging air conditioner, and a new furnace. Andrew Vasilak handled... the transaction, and he was terrific to deal with. He was helpful, informative, and there were no high pressure sales tactics. The quote was identical to what I paid.The installation of the products was superb! Both my new heat pump and furnace were installed in one day. The four men who did the installation were on time, dependable and thorough. Since the installation the heat pump has been superb. Air quality in the house is significantly better, and the air temperature has been constant. I had one minor problem, and called HAMCO late at night on a long holiday weekend for assistance. I had a return phone call back in five minutes, a repairman out to my house the next morning, and the problem was fixed quickly. The service technician who dealt with my issue was professional, polite and responsive.HAMCO has been around since 1946. They are an established Hamilton company that offers old fashioned, high quality service at a fair price. I would not hesitate to recommend them.Update: May 12/26I just had HAMCO into perform an annual inspection of my heat pump, furnace and water heater. Christian did an amazing job! He was professional, thorough and extremely detailed. He took the time to explain what he was doing, and his answers to my questions were clear and concise.I continue to be impressed with HAMCO. They do amazing work, and it is reassuring to know you can depend upon them when necessary.read more

Water Heater Installation FAQs

If you’re wondering if it’s time to call for a new water heater, here are some of our most frequently asked questions about water heater installations, and what our experts have to say in return!

There are a few telltale signs that your current water heater is on its way out and it’s time for a new model. These signs include:

The age of your water heater (if your system is over 15 years old, it may be time to replace it)
Your water heater isn’t producing as much hot water or any at all.
You notice water pooling around your water heater
You’ve noticed an increase in energy consumption and bills
You’re paying for more repairs than you once had to

The size of the tank you need depends entirely on the size of your home, the size of your family, and your water consumption habits. The experts at HAMCO are happy to help you make the decision on which size tank is best for your household.

While a tankless water heater costs more upfront, many large families and households prefer to have it to avoid running out of hot water and having to wait for more to accumulate. Similar to choosing the right size tank, the experts at HAMCO are happy to take your needs and habits into consideration and help you find the right choice for your home.

The amount of time that a water heater installation takes is dependent on the system. Traditional water heater installations take approximately 3 hours to complete. There are some water heater installations that can take 8 hours due to the complexity of the install, such as converting from a standard water heater to a tankless system.

For the most part, we recommend purchasing your water heater outright or at least choosing to finance it with monthly payments before committing to rentals. However, every family, their needs, and their budgets are different, and the experts at HAMCO are happy to take your needs into consideration when advising you on whether to purchase or rent your new system.

To find the best water heater installers in your area, go with a long-established and highly reviewed company. If you live in Hamilton, Burlington, Oakville, or its surrounding areas, you can rest assured that HAMCO is the best choice for water heater installation. With over 75 years of service and customer satisfaction, as well as high business ratings and reviews, you can feel comfortable knowing that you have the best of the best installing your water heater.

Boiler Vs Water Heater: What’s the Difference?

When in the market for a new water heater, you may come across a boiler and wonder what separates the two systems. While yes, they both heat water, they serve very different purposes in the home. Here’s what you should know.



Water Heater

Traditional water heaters, whether conventional or power vented, electric or gas, heat cold water with a heating element. As the water warms up it rises to the top of the tank, which will then flow to a location when it is demanded, such as turning on the hot water for your shower, etc. If the hot water is not being used it remains in the tank where it is continuously heated.



Tankless Water Heater

Tankless water heaters take cold water and heat it instantaneously through a heat exchanger in the system. The same as a traditional water heater, when the hot water is demanded it flows to that location i.e. turning on your hot water faucet in the kitchen sink.



Boiler

While it’s true that boilers heat water to be distributed through the home, they don’t heat water for the homeowner’s physical use. Instead, water is heated by the boiler and then it is distributed through pipes to radiators to heat the home. This is known as a hydronic heating system.



Combi Boiler

A combination boiler, otherwise known as a “combi”, is a boiler-style system that heats both your domestic hot water and your radiators. This type of system is a popular choice for people with a traditional boiler and a traditional water heater because you can replace both units with one efficient system.
