Tankless Water Heater Installation, Repair, and Replacement

Access to instantaneous hot water defines the comfort of a high-functioning South Carolina home. While traditional storage tanks keep 50 gallons of water hot 24 hours a day, a tankless system only activates when you turn on a tap. This shift from batch heating to on-demand flow eliminates the frustration of running out of hot water during back-to-back showers. Preferred Home Services specializes in the total lifecycle of these plumbing units, focusing on precision thermal exchange and maximum energy conservation.

Upgrade your home to a limitless supply of hot water by requesting a professional system consultation today.

Strategic System Installation and Seamless Unit Replacement

Moving from a bulky tank to a wall-mounted on-demand system requires more than just a pipe connection; it requires a calculated understanding of your home’s peak Gallons Per Minute (GPM) demand. Our team handles the entire transition, ensuring your new heating unit is perfectly matched to your family’s actual water usage.

  • Lowering monthly utility overhead occurs when we install high-efficiency units that only consume gas or electricity during active use.
  • Maximizing indoor square footage is a major benefit of replacement, as these compact units free up significant space in closets or garages.
  • Modernizing fuel and venting logistics ensures that your gas lines and exhaust pipes meet current safety standards for high-output burners.
  • Doubling equipment lifespan occurs when we replace 10-year storage tanks with tankless technology designed to last up to 30 years.

Our master plumbers prioritize a clean and professional setup that treats your home’s utility room with the same respect as a finished living space.

Precision Mechanical Repair and Thermal Restoration

A lack of heat or a drop in water volume often indicates a specific mechanical issue within your tankless unit. We approach every repair with a focus on restoring the fire-to-flow ratio, ensuring the internal heating elements engage as needed.

  • Isolating ignition failures to the sensors and spark electrodes can prevent the unit from firing.
  • Neutralizing temperature fluctuations addresses the internal calcification that interferes with the heat exchanger’s performance.
  • Identifying unusual vibration or noise helps prevent mechanical wear from causing a total system lockout.
  • Sealing internal supply leaks protects the sensitive circuit boards and electrical components housed inside the unit.

Every repair visit includes a comprehensive evaluation of your unit’s internal filters and safety bypass valves to ensure reliable operation during your busiest times of the day.

Proactive Descaling and Long-Term Efficiency Maintenance

The primary enemy of an on-demand heater is the mineral content found in the local water supply. Over time, calcium builds up on the heat exchanger, creating a barrier that forces the unit to work harder and run hotter. Our annual maintenance protocols include a high-velocity flush to remove these deposits and preserve your manufacturer’s warranty.

By joining our Preferred Partner Plan, you secure a scheduled defense against efficiency loss. We do not just check the unit; we perform a forensic cleaning of the burner assembly and intake filters to help keep your utility bills as low as possible.

Brian and his team did a great job working until 8pm to make sure we had water for the night and back at it early the next morning. When a problem came up they just said we going to fix you right and didn’t try to up charge. I thought the price was high until I experienced the service! Thanks guys

You CALL THEM when you need the job done right, done efficiently, and done professionally. They show up when they say they will, you get a text with a picture and info about who's showing up. They are respectful of your home putting on shoe covers, every time. They explain thoroughly everything they see and what they are going to do. Plus, they don't make you feel bad when you ask a lot of questions or when you ask for them to explain things further. Furthermore, they put a guarantee on their work! Nick Baldini has come out to our home for 2 separate issues and he is Outstanding!!! Hawk came out aswell to assist on one of them I can't be more pleased with both of them. Ask for these guys, you won't be disappointed!

Great work from tech Griffin King of Preferred Home Services. Outstanding communication skills and thorough evaluation of my 8 year old HVAC system. Great proposal on semi-critical items to get fixed before the summer AC season along with a few things that could be done next time. Ask for Griffin by name. Good guy!

Austin Henderson was a technician who came to my home today. He was very professional and he provided me with clarity of the work that could be done. In addition to that, he provided me with a full range of services offered by Preferred Home Services. He also verified the pressure on my waterline and informed me that the regulator needed to be replaced. He provided me with a number of options, all of which I was grateful for. Should we choose to work with Preferred Home Services, I would welcome having Austin be the technician to do the work.

I've been a customer for a few years after bouncing around other providers. They consistently provide quality and professional experiences and I feel they genuinely have my best interest in mind. After a number of years avoiding the inevitable, we finally came to the point of needing a full unit replacement.

The installation process was seamless and clean, with overly tidy touches and thoughtfulness from the installation team such as rodent prevention guards that could have easily been overlooked. New system is operating as expected and I trust Preferred to maintain the system for years to come.

This is the 2nd time LB has come out to help diagnose/repair problems with our HVAC system. He’s knowledgeable and takes the time to explain everything thoroughly. Each time he has offered a fair assessment of the problem and straight forward estimates for repair.

CHRIS HARBIT was an absolute GODSEND!! We’ve had a water leak for about 4 months I would say. We’ve had at least 5 people come out to assess it and told us it was a slab leak which would have cost us at minimum $8000. Chris came out and listened to our concerns and actually assessed the situation and found a leak in the INSIDE!!! This man fixed one leak and found another and this second one gave him some challenge but he never gave up and finally found a solution and it was fixed!!! I can’t tell you how relived and so full of gratitude I am. Thank you thank you so so much!!!

Becca taught me a lot about HVAC systems and electric heating which are all new to me! She took all the time I needed and explained everything in detail. She did not push anything on me, but left the choice to me. Left the place clean after she was done! Good job, Becca!
