Tankless Water Heater Installation & Service in Atlanta, GA

Tired of running out of hot water during back-to-back showers? 

Tired of running out of hot water during back-to-back showers? A tankless water heater might be the perfect solution for your Atlanta home. At Henson Mechanical Heating Air and Plumbing, we specialize in installing, repairing, and maintaining high-efficiency tankless water heaters that provide unlimited hot water on demand while significantly reducing your energy bills.

What Is a Tankless Water Heater?

Unlike traditional tank water heaters that constantly heat and store 40-50 gallons of water, tankless systems—also called on-demand water heaters—heat water instantly as it flows through the unit. This means you only heat water when you actually need it, making tankless systems far more energy-efficient. Tankless water heaters have become increasingly popular among Atlanta homeowners seeking to lower utility costs while enjoying superior performance and reliability.

Why Atlanta Homeowners Choose Tankless Systems

Energy Efficiency & Lower Bills: Tankless water heaters use 24-34% less energy than traditional tank models, according to the U.S. Department of Energy. In Georgia's warm climate, this efficiency advantage is even more pronounced since your unit works less to reach desired temperatures. Many homeowners see noticeable reductions in monthly energy bills within the first few months of installation.

Unlimited Hot Water: Say goodbye to the frustration of running out of hot water. Tankless systems provide continuous hot water for multiple simultaneous uses—multiple showers, laundry, and dishwashing all at once without compromising water temperature.

Space-Saving Design: Tankless units are compact wall-mounted systems that take up a fraction of the space required by traditional 50-gallon tanks. This is especially valuable in smaller Atlanta homes or apartments where space is at a premium.

Longer Lifespan: Most tankless water heaters last 20+ years with proper maintenance, compared to 8-12 years for traditional tanks. This longevity translates to better long-term value and fewer replacement cycles.

Environmental Benefits: By consuming less energy, tankless systems reduce your home's carbon footprint and qualify for various federal tax credits and rebates.

Tankless Water Heater Installation Process

When you choose Henson Mechanical Heating Air and Plumbing for your tankless water heater installation, you can expect a professional, hassle-free process:

1. In-Home Assessment: Our certified technicians evaluate your home's hot water demand, existing plumbing configuration, and gas or electrical supply. We'll determine the right size and capacity to meet your family's needs.

2. System Selection: We install all major brands including Rinnai, Navien, EcoSmart, and Takagi. Our team helps you select the system that offers the best balance of performance, efficiency, and budget for your specific situation.

3. Professional Installation: Our licensed plumbers handle all aspects of installation, including proper venting (for gas models), electrical connections, water line modifications, and integration with your existing plumbing system.

4. Thorough Testing: After installation, we test all connections, water temperature, and gas/electric supply to ensure everything operates at peak efficiency and safety.

5. Customer Training: We walk you through operation, maintenance requirements, and how to get the most from your new system.

Types of Tankless Water Heaters

Gas Tankless Water Heaters: These models use natural gas or propane to instantly heat water and are ideal for homes with existing gas lines. They offer higher flow rates and are often more cost-effective for larger families.

Electric Tankless Water Heaters: Perfect for homes without gas service, electric models require proper electrical infrastructure but offer excellent efficiency and require less maintenance than gas units.

Hybrid Systems: Some homeowners opt for hybrid solutions combining tankless technology with traditional tanks for maximum efficiency and reliability.

Cost Savings & Return on Investment

While tankless water heaters have higher upfront costs than traditional tanks ($800-$3,500+ depending on the model), the long-term savings are substantial:

  • Average energy savings of 24-34% annually
  • Reduced hot water loss through long pipes
  • Fewer emergency repairs and replacements
  • Potential tax credits and rebates (up to $300+ federal)
  • Georgia offers various state-level efficiency incentives

For many Atlanta families, the system pays for itself within 5-8 years through energy bill reductions alone.

Maintenance & Care

To keep your tankless water heater running optimally for 20+ years:

Annual Professional Maintenance: We recommend annual inspections and descaling (especially in areas with hard water) to prevent mineral buildup that reduces efficiency.

Regular Filter Cleaning: Monthly filter checks and periodic replacement maintain optimal water flow and protect internal components.

Professional Repairs: If you notice issues like inconsistent water temperature, reduced flow, or strange sounds, contact us immediately. Early intervention prevents costly repairs.

Tankless Water Heater Repair Services

Even the most reliable tankless systems occasionally need professional attention. Common issues include:

  • Temperature fluctuations or inconsistent hot water
  • Low water pressure or flow rate
  • Error codes or warning lights
  • Mineral buildup from hard water
  • Gas ignition problems

Henson Mechanical Heating Air and Plumbing provides rapid response for tankless water heater repairs. Our certified technicians diagnose issues quickly and provide transparent cost estimates before proceeding with repairs.

Jake from Henson HVAC provided outstanding service today! He was professional, knowledgeable, and took the time to thoroughly explain everything in a way that was easy to understand. He arrived on time, diagnosed the issue quickly, and made sure all of my questions were answered before he left. It’s refreshing to work with someone who genuinely cares about providing excellent customer service rather than just rushing through the job. If you need HVAC service, I highly recommend asking for Jake. He made the entire experience stress-free, and I wouldn’t hesitate to use Henson HVAC again because of the exceptional service he provided. Thank you, Jake!

Nick and Omar did an excellent job with my install. They were determined to get my new system up and running, no matter what that took. They were professional, arrived when they said they would, and communicated with me throughout the process. 100% recommend.

I was very pleased with the service. Both Jeremy and Scotty were friendly, helpful, and took the time to explain everything clearly. I really appreciated that I never felt pressured to move forward with the more expensive repair and was informed about the yearly membership. Both techs were honest and informative about the potential issues that could arise and explained why replacing the fan may be something to consider down the road. Overall, I had a great experience and appreciated their professionalism and honesty. And most importantly, we now have air! Zero complaints. & Shout out to the team for quickly getting Scotty out here for a visit the next day after my thermostat stopped working.

We have a three year-old and Work crazy hours and are never home. We’ve been having issues with our AC unit for about two weeks now on and off. One day it works, the next day it doesn’t. Two days ago it finally stopped working. I tried everything I could think of, because we all know googling can sometimes solve the problem. I was referred to them from a larger company who was unable to make it out the same night. It was about 8:30 PM and the operator told me I would be added to the list for the night and they could fit me in. I was expecting a call around two or 3 AM because I knew there were a few clients ahead of me. Instead, Jake called me around 9:45 pm and said he was about 15 minutes away. He was at my house until midnight fixing my problem. Turns out it was a pretty bad clog. Cleaned out the entire drain system, all the piping, and replace the condenser box for me! I would recommend them to anybody! Fast service, affordable, and the fact that they were at my house until midnight just so I could sleep comfortably, meant the world to me! I signed up for their yearly maintenance plan and I’m looking forward to working with them for many years to come!

Jake is always so amazing. I'm a local realtor and always use Henson for all my real estate need and they always take such great care of my clients. They even service my personal home. Such a phenomenal business and family.

Kaleb Graves came out for a maintenance visit on Thursday June 25. We have a unit upstairs in the attic and it is hot up there in June. Fortunately the unit downstairs is in the cool basement. One of my cats went rogue and was running loose in the house. Kaleb was closing doors behind him to help me keep the cat in the house. He stopped to talk to my 88yo dad with dementia who likes to talk about the old days. Kaleb was professional, friendly and kept our household cool.

Scotty came out to fix my shower tonight he was very professional. He communicated with me throughout the night, and now the shower is working properly. I highly recommend using Henson for plumbing, heating and air conditioning service. 5-star service!!!

Steve, the owner, was fantastic at explaining in detail the system, pricing, and overall process. Extremely thorough, and I had no questions in the end that this was the right company. No pressure to buy, no sales pitch, and I didnt feel uncomfortable as a woman that I was being pressured or scammed like I did with Casteel, who came to give a quote earlier this week. Henson's pricing was unbeatable for a bigger system, duct work replacement/size upgrading, install, and warranty. Thousands less than Casteel was "discounting", and I feel good putting money into a family business rather than a million dollar conglomerate with sales people literally thrusting their hands in my face for a deal that "when I leave the deal goes with me". I paid on the spot with Henson, knowing this was the best deal, an honest company, and ensuring a family business carries on. I would absolutely recommend them to anyone for repair, replacement, or even just a quote.
