Frequently Asked Questions
Answers to common questions about pricing, service, and equipment.
Does my 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.

We’ve got it covered. We’ll take care of draining, disconnecting, and removing your old tank, even returning it to your previous supplier.

Ali and Mehdi were fantastic today. They scheduled the job and came early and worked amazingly to finish and make sure the water heater was working. After three weeks of dealing with Reliance, I'm happy they were able to provide a quick resolution.

Mehdi and his team from GoLime did an amazing job with my new heat pump installation.
He was fast, clean and organized.
He took extra care in routing the lines and left the place neater than when he showed up.
I’m really excited to have fresh COLD air again in the home.
Thanks Mehdi and the team at GoLime!
Highly Recommended!!!

I have had a great experience with GoLime when they installed a new water heater tank and chimney liner at my home today. From start to finish, the service was outstanding. Murry and MacKenzie were professional, knowledgeable and efficient and completed the work in a timely manner and with great attention to detail. I really appreciated their clear communication and respectful approach throughout the entire process. Thank you again for a job well done.

An incredibly simple purchase experience using GoLime.com to replace my water heater. Their installation team was quick, professional and efficient. The sales and dispatch team took the time to listen and address concerns and responded quickly. Thank you GoLime team!

Ervin was very professional and service was fast and on time. I would recommend him for any water heater issues.

Of course, my air conditioner stopped working just before the heat wave last week. I was under a contract with a big-name company, but I was not pleased with their service. A friend recommended GO lime, and it was the best recommendation. I got a heat pump, tankless water heater, and furnace installed. I contacted them on June 19, and they installed it on June 21. Amir, Hossein, Milad, and Mehrdad spent all day here setting everything up. They explained everything to me and cleaned up when they were done. Go Lime went above and beyond. I needed an electrical outlet for my tankless water heater, and they had an electrician come out at no cost to me! I am not sure how they keep their prices so low and still have such excellent customer service! I highly recommend Go Lime. Do not hesitate, they are a wonderful company.
