Typical Tankless Water Heater Problems We Can Solve

  • No Hot Water: One of the most common issues with tankless water heaters is a lack of hot water. This can be caused by various factors, including insufficient gas or electrical supply, clogged filters, malfunctioning heating elements, or sensor issues. Addressing the root cause of the problem is essential to restore hot water supply and prevent further inconvenience.
  • Fluctuating Water Temperature: Fluctuating water temperature or inconsistent hot water flow can indicate issues such as mineral buildup, scale formation, or improper installation. Cleaning the heat exchanger, descaling the unit, or adjusting temperature settings may be necessary to resolve the issue and ensure consistent hot water delivery.
  • Error Codes: Tankless water heaters are equipped with diagnostic systems that display error codes to indicate specific issues or malfunctions. Common error codes include ignition failure, flame failure, sensor errors, or overheating. Understanding and interpreting error codes is essential for diagnosing and addressing problems effectively.
  • Water Leaks: Water leaks from the tankless water heater unit or associated plumbing connections can lead to water damage, mold growth, and structural issues if left unattended. Leaks may result from loose connections, damaged seals, or corroded components, requiring prompt repair to prevent further damage.
  • Gas Odors: Detecting gas odors near the tankless water heater unit can indicate a gas leak, improper combustion, or ventilation issues. Gas leaks pose serious safety hazards and require immediate attention from qualified professionals to prevent accidents or injuries.

Jared showed up on time and was very professional with diagnosing our HVAC issues. He fixed wiring and checked electrical connections to ensure no shorting issues. He diagnosed an issue with our circuit board tripping the breaker. He had replacement parts on hand and fixed the issue in a timely manner. Very professional, would definitely recommend.

Laura J.

Everyone we have interacted with has been the best. Polite, professional, responsive. We had a new water softener system installed, some plumbing redone, and water heater service. Everything was completed promptly and professionally. They are also fast to respond to inquiries. They provide great service and peace of mind. Very good service. We will use them again.

Don O.

We had a clogged toilet, bathtub, kitchen sink. Fonzi assessed the situation and gave us options on how to find a solution that worked for us. He did this politely and spoke in terms we could relate to. We continue to be pleased with their service and honest evaluations. Highly recommend this company.

Carol J.

I had I believe James and Christian come help me with a shower drain. These guys really knew their stuff and I felt comfortable with them. They even helped me fix my smoker while they were here!!! Excellent job guys. You will be my go-to from here on out. Thank you!!!

Terry D.

We were very happy with all of the staff, from the Comfort Advisor to the technicians and office support staff. The mapping of the new system was very thorough and important to the efficiency and performance of our new Heat Pump System, by expanding and adding air registers in the kitchen, bathroom en suite, and bedroom.

Valene M.

David walked into a plumbing mess of epic proportions. One that many had been unwilling to help with based on the scope of work needed to be done. He could have chosen the path of least resistance, but he stayed at our place longer than he deserved to and evaluated every element of our problem.

Vanessa T.

Luis and Silverio were very professional, knowledgeable, and efficient. They took extra measures that protect our home and cleaned any debris. I would rate them both as exceptional. Luis mentioned that someone from Wighton may come back to do a follow-up on their work. That gave me a lot of confidence.

Louis L.

Tried other so-called HVAC “professionals” to fix our issues but only Tim was able to take care of our situation. He exhibited his professional skills in diagnosing our problem and explained the repairs he was going to make to us in a manner that we could understand. Obviously knowledgeable and also very friendly.

James D.

Carlos was great! He was very professional, did a great high-quality job, and went above and beyond for us. Seems like all plumbers are very busy right now, and our service was delayed by a day because he got caught up on another job. But after seeing the quality of the work he did, it was worth the wait.

Robyn A.

Great service. Professional. The guys took a look. Quoted a price and were done and cleaned up in an hour. You get what you pay for! I’ve heard they are too expensive but it seemed fair considering the work done. Like I said though I could have found cheaper but who knows the quality? Not these guys! Quality!
