Hot Water Tanks

Hot water is a precious resource in a home or business for showering, cleaning and more. We can perform routine maintenance on your existing unit to ensure it’s in good working order, as well as install new electric or gas equipment.

If your hot water heater is more than 20 years old, or is rusting, leaking or not consistently providing hot water, it’s time to let us have a look. There could be sediment or debris negatively impacting its function that we can clear.

If it’s something more urgent, like a burst water tank that’s causing flooding, we can get there on emergency priority.

Aside from new hot water tanks, we can also install water softeners and reverse osmosis filters.


Got a furnace that’s acting up? It usually happens at the most inconvenient time – like in the middle of a cold winter night. Luckily, we can do routine maintenance or provide emergency services to keep your family warm and safe.

We are HVAC experts who can assess and repair your heating systems, and we can also offer gas fitting services if needed.

Air Conditioning

Ontario summers can be hot and humid, making properly working air conditioning units necessary. Just imagine dealing with hot weather while your air conditioner isn’t up to the task. And there are various reasons why your AC might be malfunctioning. For example, there could be a leak in the refrigerant lines, or your evaporator coils could be filled with refrigerants. Another common cause for air conditioner repair is when your unit is filled with dirt and grime. Yikes! This is why we offer high-quality repair services for AC’s. Our air conditioning contractors are highly trained to repair various units and brands of air conditioner systems. They can detect whether the unit has fan problems, leaks, and more.

Don’t have an air conditioning system yet? No problem! We have experts who are adept at installing air conditioning systems. It’s important to have trained professionals install your air conditioning unit. Why? Because you want it done right the first time.

Many considerations go into the installation of any air conditioning system. One of them is to make sure that the AC’s power levels suit the space it needs to cool. With professional help, you can also trust that the unit is installed correctly and efficiently, saving you from extra labor costs in the future. And finally, our work is guaranteed. If anything goes wrong, call us and we’ll send someone out to make it right.
