The Benefits of Going Tankless
Traditional water heaters store hot water in a tank, keeping it heated 24/7 — even when you’re not using it. A tankless water heater (sometimes called an “on-demand” water heater) heats water instantly as it flows through the system. That means no waiting, no running out, and no wasted energy.
Some of the biggest advantages of tankless technology include:
- Endless Hot Water: Enjoy continuous hot water for showers, laundry, and dishwashing without running out.
- Higher Efficiency: Since they heat water on demand, tankless units use less energy than conventional storage tanks.
- Longer Lifespan: Many units last up to 20 years or more with proper maintenance.
- Space-Saving Design: Compact and wall-mounted, they free up valuable storage space.
- Lower Utility Bills: Reduced standby heating means less wasted energy — and lower monthly costs.
At Efficient Air Service, we specialize in both gas and electric tankless water heaters, helping you choose the right system for your home, lifestyle, and energy goals.
Professional Tankless Water Heater Installation
Installing a tankless system requires more precision than a standard water heater replacement. That’s why it’s important to work with experienced HVAC and plumbing professionals who understand every step of the process.
Our installation process includes:
- Evaluating your home’s hot water needs to size your system correctly
- Checking gas, electrical, and venting requirements to ensure full safety and compliance
- Removing your old water heater and properly preparing your plumbing connections
- Installing your new gas or electric tankless water heater with attention to every detail
- Testing performance and adjusting settings to guarantee optimal efficiency
We’ll walk you through how your new system works, explain key maintenance steps, and make sure everything operates perfectly before we leave.
As with every service, you’ll experience our Red Carpet Care—meaning we protect your home, clean up our workspace, and treat your property with the respect it deserves.

Tankless Water Heater Repair
Even the most efficient systems can develop issues over time. If your water heater stops producing hot water, makes unusual noises, or flashes an error code, it’s time to call for tankless water heater repair.
Common problems we fix include:
- No hot water or inconsistent temperature
- Mineral buildup or clogged filters
- Ignition or burner failure in gas models
- Electrical issues in electric models
- Flow rate or sensor malfunctions
Our technicians use advanced diagnostic tools to quickly identify the cause of the issue. We’ll explain the problem clearly, discuss repair options, and provide an upfront quote—no surprises or unnecessary upselling.
Whether it’s a gas tankless water heater with ignition issues or an electric tankless water heater not heating properly, we’ll get your system running efficiently again. And because we offer 24/7 phone support, you can always reach us when problems arise.
Prevent Breakdowns with Tankless Water Heater Maintenance
Like any appliance, tankless systems need routine care to perform their best. Our tankless water heater maintenance services include descaling, filter cleaning, system flushing, and full performance testing to prevent problems before they start.
Regular maintenance helps to:
- Prevent mineral and scale buildup that reduces efficiency
- Extend your system’s lifespan
- Maintain consistent water pressure and temperature
- Avoid unexpected repairs or shutdowns
