I just replaced my hot water heater. I stumbled across this company online and read the good reviews. Price was much better than other companies, so I was skeptical. I called Saturday afternoon, confirmed online Saturday night, and the work was completed Sunday afternoon. I have been so impressed with the service from my phone conversation with Juan to the installation by Alireza. Now I can only hope that the product is as good as the price, technicians, and customer service.

Finally, purchased today, scheduled installation over the weekend. For comparison I have checked with Home Depot and they quoted $2200 +tax. Rheeem 50 Gallon power vent $1489 is the item they will install, so roughly $700 installation fees. They won’t return the old one. Not sure about Costco pricing, they have $300 Gift Card. I don’t think anyone else would sell less than Go Lime. Thanks.

I just had Go Lime install my new hot water tank, and everything went great. No issues at all, and you can't beat the price. Some people complained about the fan on the hot water tank being super loud, but I don’t have that issue at all. In fact, it’s quieter than my old tank

Plus, you can purchase the equipment at any time, giving you ultimate savings and flexibility.

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.

For your convenience, we ensure that your old water heater is returned to the existing provider within 30 calendar days. Our team handles the process efficiently, so you don’t have to worry about a thing. If you have any questions or need further assistance, we're always here to help.
The ideal size depends on how many people live in your home and how much hot water you use. A 50-gallon tank is the most common one. Ultimately, it varies based on your daily habits if you're unsure, we're happy to help you find the right fit for your needs.
Yes, it’s possible. However, you’ll need an electrical outlet nearby and proper venting to the exterior. Our experts can assess your setup and recommend the best upgrade option for your home.
We don’t recommend it. Installing a water heater involves plumbing, gas, or electrical connections and must meet local building codes. Professional installation ensures safe operation, optimal performance, and protects your warranty.
Most Ontario homeowners prefer renting because installation, repairs, and replacements are covered with no upfront cost. Buying is a great option if you want full ownership and long-term savings. We offer both to match your budget and comfort needs.
Replacement costs vary by size, efficiency, and installation conditions. On average, Ontario water heater replacements range from $1,500–$2,800, while rental plans start at low monthly rates with no upfront fees.
