What Customers Say

“I had no hot water, was calling around and they were the first to call back and the tech showed up within the next hour. The tech was very friendly and professional, he fixed the problem. I am always a bit intimidated when it comes to any tech/contractor who comes to my house, but he was friendly and explained the gas/electric water heater options to me the way I would understand. Highly recommended!”

- P. F.

Frequently Asked Questions

How often water heaters need to be replaced depends on a variety of factors, but you should expect to replace yours every 7 to 15 years. Factors like the model, installation quality, and maintenance of your water heater can all impact its lifespan. If you think it might be time to replace your hot water heater, call us for a free in-home assessment.

Of course, you’ll know it’s time for a new water heater if your current unit isn’t working well or isn’t working at all. The best way to know, however, is to hear it from an expert. Our expert technicians will tell you during your annual maintenance appointment or during a free in-home assessment if it’s time for a new water heater.

The installation time for your new water heater will depend on your home, but most installations will take between 2 and 4 hours. Things like the model you choose and where your water heater is located in your home can increase the installation time. To make the process as efficient as possible, make sure to clear any work areas.

We make sure your water heater is installed as quickly as possible while making sure we complete an expert installation. You can get your home ready for installation by removing any unnecessary items from the areas we’ll be working in. For most homes, this will be the furnace room and a pathway through your home.

Limcan Certified Heating & Air Conditioning Runs On Integrity

For up to 2 years from the day we install your heating or cooling unit, we will repair, replace, or refund anything necessary until you are completely happy with your new system. That’s our guarantee to you.
