Professional Water Heater Installation Services for Your Home
Traditional Tank Water Heater Installation
We install reliable tank-style water heaters from all the top brands, properly sized to meet your family’s hot water usage. Before installation, our team assesses your home’s plumbing setup and makes any required changes for a perfect fit. Every install includes accurate venting, safety valve installation, and tight water line connections to prevent leaks and ensure peak performance.

Our certified technicians understand the specific needs of tankless water heater installations, from gas line capacity and venting to any electrical requirements. We’ll help you choose the best location and make sure your new unit is installed safely and efficiently.
Electric, Gas, and Propane Models
Whether you use electricity, natural gas, or propane, we install all types of water heating systems to match your home’s existing utilities and your personal preferences. Our certified team handles electric units that need dedicated circuits, along with gas and propane heaters requiring correct ventilation and gas line sizing. We’ll guide you through the benefits of each energy source so you can make the right choice for your budget and needs.
Comprehensive System Upgrades
If your new water heater requires it, Limcan Certified can upgrade your home’s plumbing, gas, or electrical infrastructure. This could include new water pipes, upsized gas lines for higher BTU requirements, or updates to your electrical panel. Our licensed professionals ensure all work is up to code and that your new water heater performs reliably and safely.
Water Heater Replacement
We also offer complete water heater replacement, starting with safe disconnection and removal of your old system. Our team disposes of your old unit according to local environmental and recycling standards.
