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

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.

The most common furnace types are gas, electric, and oil. In Ontario, high-efficiency natural gas furnaces are the most popular due to lower operating costs and reliable performance in cold weather. The right option depends on your home’s size, insulation, and energy source availability.
AFUE stands for Annual Fuel Utilization Efficiency. It measures how efficiently a furnace converts fuel into heat. A 95% AFUE furnace, for example, turns 95% of fuel into heat and wastes only 5%. Higher AFUE means lower heating bills and less energy waste.
Most furnaces last between 15 and 20 years. Regular maintenance, like annual servicing and filter changes, can help maximize lifespan and prevent unexpected breakdowns. Not sure how often to change your filter? Check out our blog on How Often Should You Change Your Furnace Filter? for expert guidance.
Furnace size is measured in BTUs (British Thermal Units). The correct size depends on the square footage of your home, ceiling height, insulation, and climate zone. Oversized or undersized units can lead to poor efficiency and uneven heating. For a full breakdown, see our guide on How to Choose the Right Furnace Size Based on BTUs and AFUE. We also offer expert sizing assessments to help you select the right model for your space.
Single-stage furnaces run at full power whenever they're on. Two-stage furnaces, on the other hand, operate at a lower speed most of the time—only ramping up during extreme cold. This results in better comfort, quieter performance, and improved efficiency.
