Why Gas Safety Matters
Gas-fired heating equipment — furnaces, boilers and tankless water heaters — has to be installed and serviced correctly to operate safely. Improper venting, incorrect gas line sizing, or a bad connection can lead to carbon-monoxide risks or gas leaks. Our licensed technicians are trained on the gas safety steps that keep this equipment operating the way it was designed to.
- Proper gas line connection and pressure testing
- Correct venting for condensing and non-condensing systems
- Carbon-monoxide safety checks after every install or service call
- Manufacturer-specified diagnostics for safe, reliable operation
Efficiency and Your Monthly Bills
One of the biggest reasons homeowners choose Navien is the potential for lower monthly utility bills — both gas and electric — when the equipment is sized, installed and maintained correctly.
Tankless water heaters only heat water when you actually need it, instead of keeping a tank hot around the clock. Navien's condensing tankless models can reach efficiency ratings up to .96 UEF, compared with roughly .54–.72 UEF for a typical gas storage-tank water heater — a meaningful reduction in gas usage every month. (Ratings reflect manufacturer specifications; real savings depend on usage and installation.)
Navien furnaces and boilers use high-efficiency condensing technology, meaning less fuel is wasted as heat that escapes unused. Regular professional service keeps that efficiency from degrading over time, which is why our maintenance visits are built around Navien's own service checklists.
Water filtration and treatment systems help protect the rest of your plumbing and water-using appliances from scale buildup, which keeps everything — including your water heater — running efficiently for longer.

Navien questions
What Navien systems do you install and service?
Tankless water heaters (condensing and non-condensing), gas furnaces, boilers and combi-boilers, heat pumps, and water filtration and treatment systems. We handle installation, routine maintenance and troubleshooting on all of them. Our Navien certification specifically covers tankless water heaters.
Are you certified to work on Navien equipment?
We are certified for Navien tankless water heater installation, service and maintenance. For Navien furnaces, boilers, heat pumps and water filtration, we are not claiming a separate manufacturer certification — we install and service that equipment as licensed plumbing and HVAC technicians following Navien's published specifications.
Do you service Navien equipment another company installed?
In most cases, yes. We diagnose the issue, confirm the installation was done correctly, and quote the repair before starting. If we find an installation problem — venting, gas sizing, condensate — we'll show you what's wrong and what it takes to bring it up to standard.
How often should Navien tankless equipment be serviced?
About once a year for most Chicagoland homes, and more often for heavy-use or commercial units. Local water is hard, so descaling the heat exchanger through the isolation valves is the maintenance that most affects performance and service life. Manufacturers generally tie warranty coverage to documented maintenance.
My Navien unit is showing an error code. Can you help?
Usually, yes. Most error codes point to scale, venting, gas pressure, ignition or a sensor — all serviceable. We diagnose the actual cause rather than just clearing the code, and we'll tell you whether the unit is worth repairing or nearing replacement.
