Expert Water Heater Service in Mukwonago, WI

When you lose hot water, you need fast, reliable water heater service, not guesswork. Midwest Heating & Cooling provides expert water heater repair, installation, and maintenance for homeowners in Mukwonago and the surrounding Southeast Wisconsin communities. Our licensed technicians work on tank and tankless units, gas and electric, and we’re here to keep your hot water running safely and efficiently.

What Types of Water Heaters Do We Service?

The most common water heater in Mukwonago homes is the traditional storage tank model. We also see more and more tankless units as families look for higher efficiency and endless hot water.

Tank water heaters

A tank water heater stores and heats a large volume of water so it’s ready when you open the tap. These systems are reliable, cost-effective, and a great fit for many homes. We help you:

• Size the tank correctly for your household
• Replace older, inefficient units
• Fix leaks, noises, or inconsistent hot water
  

Tankless water heaters

Tankless systems heat water on demand as cold water passes through the unit. They’re compact, efficient, and can provide virtually endless hot water when sized and installed correctly. Our team:

• Installs new tankless units
• Replaces aging equipment
• Services burners, sensors, and venting to keep performance high
  

Whether you have a tank or tankless system, we offer full water heater service to inspect, clean, and tune your equipment so it runs at its best.

What Does Professional Water Heater Service Include?

During a typical water heater service visit, your technician may:

• Check for leaks, corrosion, or damage
• Inspect the temperature and pressure relief valve (pressure relief valve) for safe operation
• Test thermostats and controls
• Evaluate gas, venting, or electrical connections
• Flush sediment buildup (on tank models when appropriate)
• Verify proper water temperature and performance at your taps
  

Our goal is simple: safe operation, stable water temperature, and dependable hot water for your home.

What Is the Best Temperature for My Water Heater?

For most homes, we often recommend setting your water heater to around 120 degrees Fahrenheit (120 degrees). That level usually provides plenty of hot water for showers, dishwashing, and laundry while helping reduce scald risk and unnecessary energy use. National agencies such as the U.S. Department of Energy, EPA, and the U.S. Consumer Product Safety Commission all highlight 120°F as a practical, safe target for many households.

Your technician can:

• Measure the actual temperature at a faucet
• Adjust the thermostat for you
• Make sure a mix of hot water and cold water is delivered safely at fixtures
  

If anyone in your home has special health or safety needs, we’ll talk through the best setting for your situation.

Do I Need Water Heater Repair or Replacement?

Not every issue means you need a new water heater. During water heater service, we’ll diagnose the problem and explain your options clearly.

Common signs you need water heater repair include:

• You only get lukewarm or cold water
• The heater is making banging, popping, or rattling noises
• You see rusty or discolored hot water at the tap
• There is water around the base of the tank or unit
• You notice fluctuating water temperature during a shower
  

In many cases, a repair or maintenance visit can get your system back on track. When your water heater is older, leaking from the tank, or no longer cost-effective to fix, we’ll also provide options and pricing for a replacement.

How We Handle Water Heater Installation and Replacement

When it’s time for a new system, we’ll help you choose the right type and size based on:

• Number of people in your home
• How often you use hot water for showers, laundry, and dishes
• Available fuel type (gas or electric)
• Your energy-efficiency and budget goals
  

We’ll remove and dispose of your old unit, install the new equipment, set the temperature, and verify that every hot water fixture is working properly before we leave.

FAQs About Water Heater Service

How often should I schedule water heater service?

Most homeowners benefit from professional water heater service once a year. Regular inspections and cleanings help reduce sediment buildup, protect the tank or heat exchanger, and keep your system running efficiently.

What temperature should my water heater be set to?

For many households, a setting around 120 degrees Fahrenheit offers a good balance of comfort, safety, and efficiency. A technician can check the actual water temperature at a faucet and adjust your thermostat if needed, especially if you have small children or older adults at home.

What does the pressure relief valve do on my water heater?

The pressure relief valve (also called a temperature and pressure relief or T&P valve) is a critical safety device. It’s designed to open and release water if pressure or temperature inside the tank gets too high. During water heater service, we inspect this valve to make sure it operates correctly. If you ever see it constantly dripping, call a professional.

What are common water heater problems you can fix?

Some common water heater issues we handle include no hot water, not enough hot water, fluctuating temperatures, strange noises, leaks at fittings, and error codes on tankless units. We diagnose the root cause and recommend repair or replacement options.

How long does a typical water heater last?

Many tank water heaters last around 8–12 years, while tankless models can often last longer when properly maintained. Actual lifespan depends on water quality, usage, and whether maintenance is performed regularly.

Can I adjust my water heater temperature myself?

Some homeowners do adjust the thermostat themselves, but it’s important to be cautious, especially with gas units. If you’re unsure where the controls are or what setting is safest, it’s best to have a technician handle the adjustment during your next water heater service visit.
