Water Heater Repair & Replacement | Fast, Reliable Hot Water Solutions

Honest Diagnosis, Fair Pricing, 2-Year Warranty

A broken water heater means cold showers, no hot water for dishes or laundry, and potential water damage if the tank leaks. When your water heater fails, you need fast professional service. Henson Mechanical repairs and replaces all types of water heaters—gas tanks, electric tanks, tankless (on-demand) heaters, and hybrid systems—throughout Georgia.

Signs Your Water Heater Needs Repair or Replacement:

  1. Age: Most tank heaters last 10-15 years. If yours is older, failure is likely. Replacement prevents emergency failure and improves efficiency.
  2. Rust or Discoloration: Brown or rusty water indicates corrosion inside the tank. This usually means the tank is failing and will leak soon.
  3. Water Pooling Under the Heater: This indicates a leak. A small leak now becomes a flood later. Replace the heater immediately to prevent water damage.
  4. Strange Noises: Rumbling, popping, or knocking sounds indicate mineral buildup on the heating element. This reduces efficiency and eventual failure.
  5. No Hot Water: If your heater produces no hot water, the thermostat, heating element, or burner has failed. We diagnose and repair or replace.
  6. Inconsistent Temperature: If you run out of hot water quickly or temperature fluctuates, the tank or heating element may be failing.
  7. High Energy Bills: A failing water heater works harder to maintain temperature, consuming more energy. Replacement with a high-efficiency model saves money long-term.

Water Heater Repair Services:

For newer units (under 10 years) with single component failure, repair often makes sense:

  • Replace thermostats
  • Replace heating elements (electric heaters)
  • Repair burner assemblies (gas heaters)
  • Replace pressure relief valves
  • Flush mineral deposits
  • Replace dip tubes
  • Fix electrical connections

Water Heater Replacement Options:

1. Traditional Tank Water Heaters

Gas tanks: Heat water continuously using a natural gas burner.

  • Pros: Low upfront cost, familiar technology, heats water quickly, good for high-demand homes
  • Cons: Takes up space (40-50 gallons), uses energy continuously even when not using hot water, lasts only 10-15 years
  • Cost: $800-$1,500 installed
  • Best for: Families with high hot water demand, existing gas line available

Electric tanks: Heat water using electric resistance elements.

  • Pros: Cheaper than gas heaters, no gas line needed, compact sizes available
  • Cons: Takes up space, slower to reheat after hot water runs out, higher operating cost than gas
  • Cost: $700-$1,200 installed
  • Best for: Homes without natural gas, small households, lower budgets

2. Tankless (On-Demand) Water Heaters

Tankless heaters provide hot water instantly without a storage tank.

  • Pros: Endless hot water, saves space (compact wall-mounted units), more energy-efficient (20-30% lower operating costs), longer lifespan (20+ years)
  • Cons: Higher upfront cost, requires professional installation, may need upgraded gas line or electrical panel, slower to reach max temperature after startup
  • Cost: $1,500-$3,500 installed
  • Best for: Energy-conscious homeowners, homes with limited space, long-term value focus

3. Hybrid Water Heaters

Hybrid units combine traditional tank storage with heat pump technology for superior efficiency.

  • Pros: 40-50% more efficient than standard tanks, good for high-demand homes, lower operating costs
  • Cons: Higher upfront cost, requires proper installation space
  • Cost: $1,200-$2,500 installed
  • Best for: Energy-focused homeowners, medium-to-large households

Our Water Heater Replacement Process:

  1. Heater Assessment: We evaluate your current system's age, condition, and size.
  2. Household Analysis: We discuss your hot water usage (number of people, simultaneous uses, bathing/shower habits).
  3. Options Presentation: We present tank, tankless, and hybrid options with cost comparisons and annual operating costs.
  4. Installation Planning: We schedule replacement at your convenience and plan the work to minimize disruption.
  5. Professional Installation: We remove the old heater, install the new unit properly, test for leaks and proper operation, and ensure all connections are safe.
  6. Homeowner Training: We explain operation, maintenance, and answer questions.
  7. Warranty Registration: We register your new heater with the manufacturer to activate coverage.

Energy Efficiency Matters:

A new energy-efficient water heater can reduce your hot water costs by 25-40%, depending on the model. Over a 15-year lifespan, that's $1,500-$3,000 in savings—often covering the heater's entire cost.

Maintenance Extends Water Heater Life:

Annual maintenance helps your water heater last longer:

  • Flush the tank to remove mineral deposits
  • Test the pressure relief valve
  • Check anode rod condition
  • Inspect for leaks
  • Verify temperature settings

We offer water heater maintenance plans that catch problems early.

I got lucky to have Jake come out to service my HVAC. He did a fantastic and thorough job inspecting the equipment. He explained everything in detail and a was a great person overall to interact with. Highly recommend this company and Jake. Update: Two days later Nick and a colleague came to install a furnace for me after a crack was found in the initial inspection. They did an amazing job with the install. They would not leave without making sure I was satisfied. Highly recommend!!

Sean Woodrum from Henson Mechanical did an excellent job servicing my AC. He was professional, courteous, and very knowledgeable. He thoroughly checked the upstairs unit, cleaned it, reviewed the thermostats, and inspected the outdoor unit while clearly explaining what he found and what to expect going forward. You can tell he really takes pride in his work. Highly recommend!

The guys were informative and prompt. They walked me through the process and answered all questions. They cleaned up nicely also! I’m happy with the results. Thanks Steve

Sean came on 9/20 and said transformer was blown. 9/21 Sean installed a new transformer and fixed the electrical issue causing it to blow. Next morning ac is out again. Scotty comes and said I need a new blower motor or a whole new unit (mine is 6 yrs old). He said he couldn’t do anything to get it working. Called Estes and they came same day and fixed the blown transformer that Sean replaced on 9/21. Electrical issue was not fixed properly by Sean and thus it went out again. Estes fixed everything (electrical issue and new transformer) and 2 weeks later still running well. Jeremy the field manger said he wouldn’t refund my money for the cost of the part and labor (wasn’t asking for dispatch fee back) bc I didn’t call them again to come and fix it. Why would I have the same company come a 4th time when they proved the first 3 times they couldn’t do it? And then Scotty diagnosed a whole new problem and tried to rip me off by telling me I needed a $1200 blower motor or $8k brand new unit. Mine isn’t even at half its lifespan. Completely unprofessional and only trying to upsell. I spent 4 days with no ac in Georgia heat. I even kept the transformer they installed (see photos for serial number) to show it was blown again. Jeremy tried to claim it blew AFTER Scotty left and I didn’t call them to fix it. When Scotty left there was no ac at all so he did nothing anyways. I did call you to come and fix the problem and your tech told me he couldn’t do anything. Have tried to resolve this with them to no avail. I’ll be contacting the BBB and letting everyone in my community know not to use this company. UPDATE: Steve called me and was extremely sympathetic. He explained that this is not how they conduct business, I shouldn’t have to pay for services that were not properly rendered and agreed to give me a full refund and coach the techs who handled this. Within 10 minutes he called again to confirm my credit card would be credited. He stood up for me when no one was listening and made it right- which is all I asked for when the beginning. This company stands behind their work and has integrity and for that I say KUDOS. Thank you for making this right!!!

Sean was excellent. He came right on time, listening to my concerns, and educated me on what my “blown candle” smell really was. Turns out it was nothing and he still had a smile on his face and spent time telling me how the system works and when I should have concerns in the future. I would...
Sean was excellent. He came right on time, listening to my concerns, and educated me on what my “blown candle” smell really was. Turns out it was nothing and he still had a smile on his face and spent time telling me how the system works and when I should have concerns in the future. I would easily use this company again and ask for Sean specifically.

We called Casteel to help us figure out what was wrong with our basement heating unit. We knew upfront that the cost was $90 for someone to come out. We were then told it would be another $285 for the technician to do a leak test even though we told him where the leak was. We agreed to both of...
We called Casteel to help us figure out what was wrong with our basement heating unit. We knew upfront that the cost was $90 for someone to come out. We were then told it would be another $285 for the technician to do a leak test even though we told him where the leak was. We agreed to both of these costs. He said Casteel "was not in the business of repairing coils" but they would give us a quote if we wanted one. He then told us the cost to repair the coils would be approximately $6500 (even though the coil was still covered by Trane's warranty) or we could replace the unit for approximately $15,000. Mind you, we have lived in this new construction, custom built home for 5 years. When I asked about this unit being so new, he told me "It's mechanical and mechanical things break." We were put off by the astronomical quote, the attitude and the feeling that we were getting scammed to some degree. We took the quotes and told him we were going to check with other companies. We got a referral to a smaller company, Henson Mechanical out of Monroe, Ga. They are a smaller, family owned business. We explained what we learned from Casteel, but we did not tell them what they wanted to charge us. Henson did not charge us to come out to our home, they did not run another test, and they were very responsive to our questions. The owner of Henson came out himself (arrived around 8:15 in the morning) and said he didn't need to run a test; he said he could see where it was leaking without a test. He gave us a quote of $2700 to replace the coils. Since the unit was still under warranty, Mr. Henson went out to Duluth, picked up the warrantied part, and had his guys replace the coil all by 3:00 that afternoon. The two men from Henson that fixed our heater were professional, polite, and knew what they were doing. To say our experiences with the two companies are night and day would be an understatement. We literally spent less than half of the repair price given to us by Casteel for the same work. We even signed up for Henson's annual maintenance plan for $225 per year, and we still were less than half of Casteel's original quote. Please do not use Casteel. They are overpriced and put their financial gain before their customers. We will continue to use smaller, family owned businesses like Henson Mechanical whenever possible. We could not recommend Henson Mechanical more, and we are thankful for the referral to them. You get people who care with better customer service and cost. Thankful we were smart enough to get a second opinion!

Jake is the man! Here is a guy truly with a heart to serve who provides excellent customer service. He’s the kind of guy that does such a great job you just want to cook him dinner as a thank you! 😊 We had a part that needed replaced in our unit and he came over after hours, walked us thru everything that was going on with the unit. He is truly knowledgeable and quite a professional! When all was said and done, he was able to fix the problem on the spot at an affordable price that was truly a blessing to us! We highly recommended him! And to the credit of One Hour, all of the technicians we’ve had have been superb. We can definitely add Jake to the hall of fame. Thank you so much for your service, Jake. You’ve been quite a blessing!

Your HVAC and Plumbing Questions
Expertly Answered

Do you service emergencies after-hours?

Definitely! We offer 24/7 emergency HVAC repair near me services and plumbing emergency support to keep your home comfortable no matter the time or day.

How much will my service cost?

Service cost depends on the size of your HVAC system, plumbing needs, and repair complexity. Our certified technicians perform a thorough analysis and provide a transparent, upfront quote aligned with our Straightforward Pricing policy—no surprises, guaranteed.

How often should I service my HVAC system?

To maintain peak efficiency, schedule residential HVAC maintenance service annually—air conditioning in spring and heating services in fall. Regular checkups help prevent costly breakdowns and ensure year-round comfort.

How often do I need to change my HVAC filter?

Replacing your HVAC filter every 1-3 months is optimal. Frequency varies depending on your household environment and external conditions to maintain air quality and system longevity.

Do you offer purchase financing?

Yes! We collaborate with trusted lenders to provide flexible financing options, helping you afford heating and air conditioning repair, installation, or plumbing upgrades. Discuss financing options with your technician during your appointment.

What are the advantages of a smart Thermostat?

Smart thermostat installation offers many benefits, including learning your household schedule, optimizing heating and cooling, remote smartphone control, and reducing energy expenses—boosting efficiency while enhancing comfort.

How long should a water heater last?
  • Tank heaters: 10-15 years. Tankless heaters: 20+ years with proper maintenance. Hybrid heaters: 15-20 years.
    • What temperature should I set my water heater to?

    120°F is standard and safe. Higher temperatures increase energy use and burn risk. Lower temperatures may not kill bacteria in the tank.

    Is a tankless water heater worth the extra cost?

    For many homeowners, yes. The 20% lower operating costs recoup the higher upfront cost in 5-8 years. Plus, endless hot water is a major lifestyle upgrade.
