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.

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.

Great service from golime . My second tank died in 9 years , on thursday night. I start calling on friday , trying to get a replacment Asap. GoLime were able to schedule me the next day , which was Saturday, and all other companies, including local guys and big companies, said the best they can do is Sunday or Monday. Rizwan was very professional and explained all the options and answer all of the questions
The next day Mehdi did the install. Also very professional and polite. He removed the old tank , installed the new tankless unit. Everything was done fast and he cleaned up everything after himself.
Very happy with my choice so far.

I had an absolutely amazing experience working with Rizvan from Go Lime! From start to finish, he went above and beyond to help me get the perfect tankless water heater and furnace for my home. Rizvan took the time to understand my needs, walked me through all the available options, and made sure I chose the right specs tailored to my space.

What really stood out was how knowledgeable and attentive he was, he stayed in touch throughout the entire installation process, ensuring everything went smoothly and according to plan. Any questions I had, Rizvan had clear, confident answers. It's rare to find someone so dedicated and well-informed.

Thanks to him, I now have a highly efficient system that works perfectly for my home. I can’t recommend Rizvan and Go Lime enough!
