Frequently Asked Questions

Does the monthly price ever go up?

Our pricing isn’t a flashy promotional rate - it’s fair and transparent from the start. Over time, there may be minor adjustments to ensure you continue receiving top-notch service. But don’t worry - we’re talking about just a dollar or two per year at most. No surprises, just straightforward savings. Plus, you can purchase the equipment at any time, giving you ultimate savings and flexibility.

What happens if I move?

Moving? No problem. Our Go Flex plan is fully transferable to the next homeowner, allowing them to seamlessly pick up where you left off. Just let us know 30 days before your move, and we’ll handle the rest. We’re here to make your move hassle-free, just the way it should be.

What happens to my old tank?

We’ve got it covered. We’ll take care of draining, disconnecting, and removing your old tank, even returning it to your previous supplier. If you’re still under contract, you’ll be responsible for any fees or buyouts from your current provider. You won’t have to lift a finger (except maybe to wave goodbye to the hassle).

What is the warranty with my purchase?

With the Go Flex Program, you’re 100% covered—24/7/365—for both parts and labour, including annual maintenance. If you choose to purchase the equipment, you’ll receive the standard manufacturer’s warranty. Start with the Go Flex Program to enjoy all the benefits we offer, and when you’re ready, you can purchase the equipment at your convenience.

How long have you been in business?

Go Lime has been keeping homes comfortable since 2011. With over 150,000 customers across Ontario, we’ve spent more than a decade earning the trust of homeowners just like you. Partnering with trusted names like Enbridge, Home Depot, and Walmart, you can count on the Go Lime team to take care of your family.

Is Go Flex a rental, and what is the term?

Go Flex isn’t a never-ending rental contract. It’s a game-changer: an industry-first flexible 180-month subscription with an anytime purchase option. Here’s how it works: 50% of your monthly payment reduces your purchase price, while the other 50% covers 24/7 service, annual maintenance, and unlimited parts and labour coverage. You get all the perks of ownership without the headaches—and the flexibility to purchase the equipment at any time.

More than 18,000 homeowners in Ontario trust Go Lime with their hot water needs. We deliver choice, transparent buyouts, and best price in Ontario.
