Tracy G.
Tankless water heater installed. Works amazing! The guys came out, punctual, they kept us involved with every step of the installation, consulted us on heater and every pipe including what they will do when we have them back to flush the system. Excellent knowledge of products and services that they (the company as a whole) provide!

Colton and Quenton replaced my water heater with a tankless system, added a halo5 water purifier & repaired an outdoor faucet, plus the supporting plumbing connections in the attic and also chased down parts during the day as required.
Jessica G.
I woke this morning to a non functioning heater. I called and was given an immediate appointment. The tech was prompt, polite, and worked quickly to get my system back up and running. The cost was affordable and I appreciate Javier being patient and explaining what he needed to do to get things working again. He had to leave for a part but quickly returned to get it installed.

Our A/C unit went out and On Time was able to get us scheduled for less than 24 hours later. With a 4 week old at home and 95 degree weather, we were SO grateful. The technician who came out to work on our unit was wonderful. He was efficient, professional and knowledgeable. He was able to have our unit up and running within 15 minutes. Overall, we are thrilled with the help we received and would absolutely call On-Time again if needed!

Signs Your Tankless Water Heater Needs Repair or Replacement

Tankless water heaters are built to last, but they are not maintenance-free. Knowing when something is off can save you from a cold shower or a more serious problem down the road.

Watch for these warning signs:

  • Inconsistent or fluctuating water temperature
  • Error codes displayed on the unit
  • Reduced hot water flow or pressure
  • Unit takes longer than usual to heat water
  • Unusual noises during operation
  • Visible corrosion or mineral buildup on the unit
  • Higher than normal energy bills
  • System shuts off unexpectedly during use
Wichita’s hard water is a contributing factor worth mentioning here. Mineral deposits from calcium and magnesium can build up inside a tankless unit over time, reducing efficiency and eventually causing damage if the system is not flushed and serviced regularly. If your unit has not been descaled in a while, that alone can explain a lot of the symptoms on this list.

Why Wichita Homeowners Are Switching to Tankless Water Heaters

Traditional tank water heaters keep a large supply of water hot at all times, even overnight and during the hours when no one is home. That constant energy use adds up over the course of a year. Tankless systems heat water on demand instead, which eliminates that standby energy loss and results in meaningfully lower utility bills for most households.

The other major advantage is endless hot water. A tankless unit heats water as it flows through the system, so you are not limited by the capacity of a storage tank. For larger households or homes where multiple people are showering and running appliances at the same time, that difference in daily comfort is significant.

Tankless water heaters also take up far less space than traditional units. They mount on a wall and free up the floor space that a bulky tank would otherwise occupy, which matters in smaller utility areas or tight mechanical rooms.

Lifespan is another factor that makes the switch worthwhile for many homeowners. A quality tankless unit that is properly maintained can last 20 years or more, compared to the 10 to 12 year average lifespan of a traditional tank heater. Over the long run the investment tends to pay for itself.

Our Tankless Water Heater Installation and Repair Services

Whether you are installing a tankless system for the first time or need repairs on an existing unit, we handle the full scope of the work so you do not have to coordinate between multiple contractors.

For installations, we start by evaluating your home’s hot water demand, the size of your household, and your existing gas or electrical infrastructure to make sure the system we recommend is properly matched to your needs. Sizing a tankless water heater correctly is critical. An undersized unit will struggle to keep up during peak demand, and getting that calculation right from the start is something we take seriously on every job.

For repairs, we diagnose the issue thoroughly before recommending any parts or work. Common repairs we handle include replacing ignitors and flame sensors, clearing mineral buildup through professional descaling, addressing flow sensor issues, repairing or replacing heat exchangers, and resolving error codes related to venting or gas supply. We carry common parts on our service vehicles so most repairs can be completed in a single visit.

When You Need Emergency Tankless Water Heater Service

A tankless water heater that stops working entirely means no hot water in your home, and that is not a situation most households can go without for long. Whether the unit is throwing an error code that will not clear, has stopped heating water completely, or is leaking, those situations warrant an urgent call.

On Time Plumbing, Heating, Cooling, and Electric offers 24/7 emergency service for water heater issues that cannot wait. If your system goes down outside of normal business hours, we are available to respond. We will diagnose the problem, give you honest options, and work to get your hot water restored as quickly as possible.

Frequently Asked Questions

How long does a tankless water heater installation take?
Most installations can be completed in a single day. If upgrades to your gas line, venting, or electrical supply are needed to support the new unit, the timeline may be slightly longer. We will give you a clear estimate before any work begins.
A quality tankless unit that is properly maintained typically lasts 20 years or more. Regular descaling and annual servicing are the most important things you can do to protect that lifespan, especially given Wichita’s hard water conditions.
Yes, with proper sizing. Larger households with higher simultaneous hot water demand may need a higher capacity unit or in some cases two units installed together. We assess your household’s needs before making any recommendation to make sure the system we install can actually keep up.
Annual servicing is recommended for most units. In Wichita, where hard water mineral buildup is a real concern, regular descaling is especially important to keep the system running efficiently and prevent damage to internal components.
For most homeowners, yes. The energy savings, longer lifespan, and improved comfort add up over time in a way that makes the investment worthwhile. We can walk you through a straightforward cost comparison based on your current setup so you can make the decision that makes the most sense for your home.
