I had the pleasure of speaking with Lindsay when I called Harding yesterday regarding an issue with our air conditioning. With the weather heating up, our home had been reaching uncomfortable... temperatures as high as 26°C for the past two weeks, and we were really starting to feel it.What truly stood out was how kind, professional, and genuinely helpful Lindsay was throughout the entire process. We reached out just before a long weekend—one of the busiest times of the year—and despite the tight scheduling, Lindsay went out of her way to ensure we wouldn’t have to suffer through the heat. She arranged for a technician to come to our home at the end of his shift that very same day. Thanks to her, we were able to enjoy a cool and comfortable home over the long weekend.Lindsay went above and beyond to help us, and her customer service was truly exceptional. We’re so grateful for her assistance. Thank you, Lindsay, for your dedication and for making such a big difference—we really appreciate it!The technician Jon Houde come to our home to repair our air conditioning, which hadn’t been working for over two weeks. Like I mentioned earlier, when he arrived, our house was sitting at a sweltering 26°C, and we were beyond ready for some relief from the heat.What truly impressed us was that Jon came all the way from his last service call in Winchester to our home in Cumberland—right before the long weekend, no less. That kind of dedication is rare and so appreciated.Jon was incredibly kind, professional, and patient. He took the time to thoroughly explain what was going on with our system and made sure we understood the issue and the fix. It was clear from the start that Jon takes a lot of pride in his work. He mentioned he’s been with the company for quite some time, and it absolutely shows. His experience, attention to detail, and genuine care for his customers really stood out.Thank you so much, Jon, for going the extra mile (literally) to help us out. Your hard work and dedication didn’t go unnoticed, and we’re so grateful you made time for us right before a busy long weekend!read more

I am very happy with my purchase and the fireplace installation. My wife and I have used it multiple times since it was installed and it works exactly as advertised. It turned a cold room in to a... comfy room that we thoroughly enjoy.My wife and I were leaning towards purchasing a fireplace with high BTU output and a fan. The team at Harding pushed back, and said we would be too hot. I appreciate their honesty. Consider they gave up a bigger sale.The installers (James + Adam) were thorough, neat and patient answering our many questions. I told them that my former wood fireplace had an ice-cold hearth. I asked them why, and they showed me that the original fireplace was not assembled correctly; it allowed cold air to come down around the fireplace, especially the hearth. It was awful. I really appreciated how they sealed the leak and added insulation. The problem was eliminated.The finishing team (Brandon and colleague) were also meticulous. They did not rush the job. I was out of town during the finishing and they suggested WhatsApp video calls, which worked very well and allayed my concerns.I would especially like to acknowledge Kirsten Neumarker. She is the project coordinator at Harding who schedules resources to install and finish fireplaces. She is very organized and is an excellent communicator. She reached out to me proactively and worked hard to accommodate my schedule also. She would often answer my emails and phone calls in minutes. I find this uncommon among contractors. She made a difference.Overall, a positive experience and I recommend them without reservations.Oh, and check out the photo attached of the finished product. We love it!Mikeread more

Tankless Water Heaters
Tankless water heaters can provide an endless supply of hot water, and that’s why so many Ottawa residents choose to install them. Tankless water heaters heat water on demand, making them more efficient than standard tanked water heaters. But, if you need to supply multiple appliances and faucets at once, tankless water heaters may not be the best choice for you as they might not be able to produce enough hot water at a time.
Tankless vs. Tank Water Heaters
Tankless water heaters generally come with greater benefits than traditional storage tank water heaters. This is especially true if you’re not looking to replace your existing tanked water heater with a tankless water heater. However, if you’re looking into switching from a storage tank to a tankless water heater, you’ll still benefit in the long run. This is because tankless water heaters last longer and are typically more efficient to operate.

Benefits of Installing a Tankless Water Heater
Unlimited Supply
You won’t have to limit your showers to 5 or 10 minutes. A tankless water heater heats the water on demand so you have a limitless supply of hot water. Hot water is always available when you have a tankless water heater.
Energy Efficiency
Tankless water heaters only heat water as needed, whereas tanked heaters heat and reheat a constant supply of water all the time. This makes tankless systems more energy efficient.
On top of that, there are ENERGY STAR certified tankless water heaters, which can save you up to 30% more energy compared to standard storage tank water heaters.
Cost Savings
As mentioned, tankless water heaters use less energy. This saves you money on energy bills. Plus, there are models that allow for re-circulation so you can have faster water at your faucet and less wasted water. This can also save you money on your water bill.
No Water Damage
Since there’s no storage tank, you know you’ll never experience a leak or flood like homes with a traditional storage-tank water heater have the potential to.
Longer Lifespan
Compared to tanked water heaters, certain tankless models can last up to twice as long and have twice the warranty. Most tank water heaters last around 10-15 years, while tankless heaters can last for up to 20 years or more.
Cleaner Water
Traditional hot water heaters with tanks keep a constant supply of water sitting inside the tank at all times. This allows for the buildup of mineral deposits. Since there’s no tank with a tankless model, the water is cleaner.
Save Space
Tankless units are about the size of a small suitcase, whereas storage tank water heaters usually require a clearance of 60 inches (152 cm) of height and 24 inches (60 cm) of width. This takes up quite a bit of valuable floor space. If space is already limited in your house, a tankless water heater is a better option.
Better Control
With certain tankless heaters, you can use digital controllers to adjust the output water temperature as you desire. Some models even have recirculation technology, which learns your hot water usage patterns and schedules recirculation accordingly. With this feature, you get hot water faster and exactly when you need it.
Is It Time to Replace My Tankless Water Heater?
If you have an older or inefficient water heater, you may be wondering whether or not it’s time for a replacement. If your tankless water heater exhibits one or more of the following signs or characteristics, it may be time to get a new water heater installed:
- Leaking
- Reduced pressure
- High energy bills
- Older than 15 years
- Making strange noises
- Rust on/around the system
- Not producing enough hot water
- Inconsistent water temperature
Tankless Water Heater Repair & Maintenance
Problems with your tankless water heater can be stressful, but it might not mean it’s time to replace the system. If you notice a leak, have no hot water, or your water heater just isn’t performing like it should, contact Team Harding. We provide expert advice and exceptional tankless service.
Ottawa homeowners have been relying on Team Harding for water heater service, repair, and maintenance since 1994.
