Tankless Water Heater Services in the DMV

If you’re tired of running out of hot water or paying high energy bills to keep a traditional tank heated around the clock, a tankless water heater may be the solution. At Frosty’s Heating & Cooling, Inc., we install, repair, and maintain tankless water heaters throughout Northern Virginia, Washington, D.C., and Maryland. These systems heat water only when you need it—providing on-demand comfort, better energy efficiency, and space-saving convenience.

Our team is here to help you understand whether a tankless system is the right fit for your home, and to ensure expert installation and long-term reliability.

Advantages of Tankless Water Heaters

  • Endless Hot Water: Tankless systems heat water as you need it—perfect for households with high demand or large families.
  • Energy Efficiency: Because they don’t store hot water all day, tankless models use significantly less energy than traditional tanks.
  • Longer Lifespan: With proper maintenance, tankless units often last 15–20 years or more—outlasting most standard water heaters.
  • Space Saving: Compact and wall-mounted, tankless units free up valuable storage space.
  • Lower Utility Bills: Less energy usage translates to long-term cost savings on monthly bills.

Tankless Water Heater Installation

Installing a tankless water heater requires careful system selection and professional installation to ensure optimal performance. At Frosty’s Heating & Cooling, Inc., we assess your home’s hot water needs, gas or electric availability, and existing plumbing to recommend the right model. Our certified technicians handle every step—from removing your old water heater to integrating the new unit with your home’s plumbing and power supply.

We make sure your tankless system is properly sized and installed for reliable, efficient operation from day one.

Tankless Water Heater Repair

Even the best systems need occasional service. If your tankless water heater is displaying an error code, not heating water consistently, or has low water pressure, our team can help. We diagnose and repair issues quickly, using quality parts and trusted techniques to restore your hot water without delay. We service all major brands and models and offer transparent, no-pressure repair recommendations.

Tankless Water Heater Maintenance

To get the most out of your tankless water heater, regular maintenance is essential. Our tune-up service includes descaling the system (especially important in hard water areas), checking filters, inspecting electrical and gas connections, and testing performance. Annual maintenance helps prevent mineral buildup, extends the life of the unit, and ensures consistent water temperature when you need it most.

Protect Your Comfort and Your Wallet

Regular HVAC maintenance is one of the smartest ways to protect your heating and cooling system—and your budget. With a professional tune-up each year, your system runs more efficiently, lasts longer, and is less likely to break down when you need it most. That means fewer unexpected repairs and more reliable comfort during every season.

By keeping your system in peak condition, you’ll also lower your energy bills. A well-maintained HVAC system doesn’t have to work as hard to heat or cool your home, which translates into real savings month after month. In many cases, those energy savings can even offset the cost of your annual maintenance. It’s a simple investment that pays for itself in peace of mind and performance.

Tankless Water Frequently Asked Questions

How does a tankless water heater work?

Tankless systems heat water on demand using gas or electricity. When you turn on a hot water tap, the system activates and heats water instantly as it flows through the unit—eliminating the need for a storage tank.

Yes, when properly sized. Larger homes or homes with simultaneous hot water use may require a higher-capacity unit or multiple systems. We’ll help you choose the right configuration.

The upfront cost is higher than a traditional tank, but many homeowners see long-term savings through reduced energy bills and longer equipment lifespan.

Most units last 15 to 20 years with routine maintenance, which is significantly longer than the typical 8 to 12 years for standard water heaters.

Annual service is recommended. This includes descaling the unit (especially in hard water areas), checking for buildup, cleaning filters, and testing for safe operation.

Yes, but it often requires updates to your plumbing, gas lines, or electrical system. Our team will assess your home and guide you through the conversion process.

There may be local or federal incentives for upgrading to an energy-efficient system. We can help you explore available rebates or tax credits.

Yes. Quality systems are designed to work year-round, even in colder temperatures. Proper sizing ensures you’ll have consistent hot water in all seasons.

Gas models typically offer higher flow rates and are more suitable for larger homes. Electric models are easier to install and work well in smaller applications or homes without gas access.

In many cases, installation can be completed in one day. We’ll schedule promptly and complete the work efficiently with minimal disruption to your home.
