Professional company. I got a competitive quote. Technician came on time, completed the work and cleaned up after. Took about 2 hrs to remove the old tankless and install the new unit. A smooth process and I'm happy with the work. Thank you.

I had a regular hot water tank replaced with a tankless type by HVAC Ontario. Abdullah and Bilal were very helpful, courteous and professional from the start and even with after care. The technicians they sent who installed the furnace were very caring and professional as well. They walked us through how the system work. Awesome!

Frequently Asked Questions

When it comes to buying a new tankless water heater for your home, making an informed decision can save you thousands of dollars. Here’s what you need to know before installing your tankless water heater.

  • When deciding between renting and buying a tankless water heater, it's essential to weigh the facts for a well-informed choice.
    Renting Option: Renting may appear enticing with no upfront costs and comprehensive parts and labor coverage. However, the convenience comes at a considerable price. Over the rental term, you might end up paying more than three times the total cost of purchasing. On average, homeowners can spend over $10,000 throughout the lifespan of a rented tankless water heater, and yearly rental fees tend to escalate. Moreover, potential challenges arise when selling your home, as new owners may be deterred by the additional rental expense.
    Buying Option: Opting to buy a tankless water heater is a financially savvy decision for several reasons. Firstly, there are no ongoing rental payments, leading to significant long-term cost savings. Despite the absence of rental fees, purchasing a unit ensures continued coverage with a parts and labor warranty. This not only provides financial security but also eliminates the risk of rising annual rental fees. Buying allows homeowners full control and ownership of the system, making it a more cost-effective and flexible solution over the long run.

  • Tankless water heaters heat water only when needed, eliminating the need for a storage tank. Traditional tank water heaters store and maintain a fixed volume of hot water at all times. Tankless units provide instant hot water, saving you energy and space with unlimited supply of hot water.

  • The cost varies depending on factors like brand, model, and installation complexity. On average, you can expect prices ranging from $2,800 to $3,500. Consider long-term energy savings and performance when evaluating the overall value. Speak with our tankless water heater pro to get an exact quote over the phone. Call now 1-888-705-7368.

  • Determining the right size involves considering your household's hot water demand. Our tankless water heater experts can recommend the right hot water solution for your home. We will evaluate factors like the number of bathrooms, simultaneous appliance use, and your climate. This ensures you choose a unit with the appropriate capacity to meet your specific requirements. We carry Rinnai Ru160 tankless water heaters (9 GPM), Rinnai Ru199 tankless water heaters (11 GPM), and Rinnai RSC recirculating tankless models for instantaneous hot water on demand.

  • Tankless water heaters offer several advantages, including energy efficiency, space savings, and continuous hot water. Their longer lifespan and reduced standby heat loss contribute to cost savings over time. Additionally, tankless units are environmentally friendly, as they consume less energy compared to traditional tank water heaters.
