Whether you're considering a modern, energy-efficient tankless water heater or your current unit is struggling to keep up, making the right choice for your home's hot water needs requires expert guidance. Dayco Systems provides comprehensive tankless water heater installation and repair services across Metro Atlanta, keeping your water running hot and your daily routine moving smoothly.

Is Your Tankless Heater Struggling?

Consistent hot water keeps your morning routine running on schedule. As such, catching minor performance changes early makes it easy to schedule professional tankless water heater repair before a small issue interrupts your day. Homeowners should watch for several clear warning signs:

  • No hot water: The tap runs with normal pressure, but the water stays lukewarm or cold, no matter how long you leave it running.
  • Fluctuating temperatures: Your shower turns chilly midway through or alternates between hot and cool water during normal use.
  • Error codes: The digital display on your system flashes a specific service code or warning light.
  • Unusual noises: You hear unexpected sounds like banging, rumbling or popping coming from the unit while hot water runs.
  • Visible moisture: Small drips or damp spots form along the outer cabinet and connecting pipe fittings.

If you notice these issues, our plumbing services team can diagnose the problem and restore dependable performance.

Tankless Water Heater Repair

Tankless systems require specialized knowledge for effective repairs. Our technicians bring the diagnostic tools and technical understanding to address performance issues throughout Metro Atlanta.

Our repairs address mineral buildup, ignition and flame failures, faulty temperature sensors and flow rate issues. We employ proven techniques to restore hot water in your home.

Tankless Water Heater Installation

Instead of continuously heating dozens of gallons inside a large storage vessel, a tankless unit heats water on demand as it flows through the system. Tankless water heaters can provide continuous hot water when properly sized for the home, and may also help reduce energy costs.

When installing a new water heater, our experts evaluate your home's water demands and typical usage patterns. Based on our assessment, we can recommend the appropriate size and type of tankless water heater for your home. Our technicians install and service gas tankless water heaters from all brands.

Our installation process addresses all mechanical, electrical and venting requirements. While the initial cost of a tankless water heater is higher than that of a conventional tank, ongoing utility savings help offset that investment over time. To make the transition even more manageable, you can explore flexible financing options to divide the investment into predictable monthly payments.
