Common Water Heater Problems We Repair
When your hot water heater isn’t working, there’s usually a specific component to blame. Our experienced technicians are trained to diagnose and repair a wide range of water heater issues, including:
Heating Element Failure
If your water isn’t getting hot, the electric heating element may be burnt out. We’ll test and replace it as needed, restoring hot water quickly and safely.T&P Relief Valve Issues
This critical safety valve helps prevent your tank from over-pressurizing. If it’s leaking or stuck, we’ll assess it and ensure your system is operating safely.Faulty Drain Valve
A malfunctioning drain valve can lead to leaks during flushing or make routine maintenance impossible. We can replace or reseal it to ensure proper performance.Clogged Intake Filter
Sediment and debris can block the intake filter, limiting water flow or causing efficiency problems. We’ll clean or replace it as needed.Broken or Inaccurate Thermostat
If your water is too hot, too cold, or inconsistent, your thermostat may be misreading or failing. Accurate control is key to both comfort and energy savings.Leaking Connections and Fittings
Over time, joints and fittings can corrode or loosen, causing drips or pooling water. We’ll inspect and secure all connections to prevent water damage.
Whether your system needs a quick repair or a deeper diagnostic, our team comes equipped with the tools and training to fix the problem with precision and care.
Preventative Maintenance Tips to Extend the Life of Your Water Heater
A well-maintained water heater can last years longer, reduce your energy bills, and prevent costly emergencies. Here are a few preventative measures we recommend:
- Annual Tank Flushing: Sediment build-up is a leading cause of heater inefficiency and early failure. An annual flush removes debris and helps maintain consistent water temperature and pressure. Multiple reviewers mentioned how helpful and clean our technicians were during these routine service visits.
- Inspection of Anodes, Thermostats, and Heating Elements: The anode rod helps prevent corrosion inside your tank, while thermostats and heating elements ensure proper operation. Regular inspections help catch issues early before they lead to full system failure.
- Monitor for Early Warning Signs: Watch for unusual sounds (like rumbling or popping), discolored water, or fluctuations in water temperature. These can be signs of internal buildup, malfunctioning parts, or tank deterioration. Don’t wait until there’s no hot water at all — early detection is the best way to save money and stress.

“NEXTGEN repaired my HVAC system which had an intermittent heating problem on a timely basis and it was covered under warranty. The technician was very polite an professional.”- Mark R.

“My thermostat took a dive on me so I went to replace it. That's where I met Breanna at Home Depot she advised me on the Ecobee one and normally I don't use big companies because of cost is always higher since they have higher overhead. However, at $49 for a diagnostic they sent someone out and that's when things got even better Lazaro was our technician. He was trustworthy and communicative and effective at explaining to me and my wife what he's doing to our unit and why. In the end because of his demeanor and character I chose to get work done through his company. I got an ionizer placed and he patched a few areas where air was escaping. Cleaned condenser and added a second capacitor and cleaned the fan on inside of my house as well as checked the coils which were fine. In summary the company is trustworthy or at least my experience was good. At at a $49 diagnostic fee it was worth it to have someone come out and let me know where I'm at. Can't say enough though about Lazaro he sold me on trusting next gen so if everyone is like him you'll find value.”- S.S.

“My technician Joseph was a solid and upstanding dude. He took his time doing an inspection of my old hvac system. He let me hover over him and helped educate me on the different components of the furnace and AC units. He didn’t tell me what I wanted to hear, but he told me what I needed to hear. Would trust him and his team to do my maintenance and future installs for my home.”- Andrew W.
-
“My AC stopped working and gave me a power failure message. Ryan was dispatched as the technician to assist. He was great, he quickly diagnosed the issues (fuses and capacitors). He gave me practical solutions and was great to work with. If I have issues in the future I will be asking for him specifically.”- Roger D.
-
“Gabe was so efficient and explained everything so we could understand. He took his time to thoroughly look at all of our concerns and figure out some type of solution. I appreciate his taking the time with us!”- Carly N.
-
“Ryan was extremely professional and knowledgeable. He took the time to thoroughly explain everything in a clear, detailed way, which I genuinely appreciated. He was clean, respectful of our space, and very thorough in his work. You can tell he takes pride in what he does. He went above and beyond, and his kindness and professionalism did not go unnoticed. Highly recommend.”- Erika A.
