Cost of Replacing a Water Heater

Taylor Drews February 2024 Milwaukee water heater repair service 5 star review

"We live in a high rise condo downtown with an in unit water heater and had difficulty finding someone to come out and look at it. Ty came in and did a great job. Very respectful of our property and time. He replaced the heater efficiency and spotlessly. It was a pleasure working with Prompt Heating and Cooling, I recommend them to anyone looking for service."

  • Will the new water heater be a conventional or tankless model?
  • Do you need us to haul your old water heater away?
  • Condition of the vent duct, plumbing & connections
  • Whether any electrical breakers need to be added

Every situation is a bit different. Your best bet is finding a local company with good reviews and getting a quote for water heater replacement.

Repair vs. Replacing a Water Heater

Age is the most important factor when deciding whether to repair or replace a water heater. Systems near the end of their service life requiring major repairs are usually better replaced with a newer, more efficient model.
Signs replacement may be the better option include:

  • Water heater is more than 10 years old
  • Hot water output has declined
  • Temperature must be set higher to achieve the same results
  • Energy bills are increasing
  • Frequent repairs are needed

If your existing unit can be safely repaired and continue operating reliably, we will recommend repair instead of replacement. Our goal is the most cost‑effective solution for your home.
We work with all types of water heaters and can help with the maintenance of your new one. If we can repair your current water heater and give you more good service life out of it, we will.

My central air stopped working yesterday and I went online to try to find just the right company to call. After reading so many glowing reviews, I decided to go with Ty and Prompt Heating and I am so glad that I did! Ty had an appointment available that fit perfectly with my schedule this morning. He arrived right on time and could not have been any more polite or pleasant. He quickly assessed the problem on my fairly elderly air unit and was able to fix it immediately while answering all of my questions and concerns. There was not an ounce of pressure to fix or replace anything that was not needed and Ty reassured me that my older central air unit had some good life left in it and that I could certainly wait until a later time to replace it. When asked, he gave a very easy to understand explanation of how this unit works and some suggestions on trimming back a bit of my outside garden to make sure it was able to operate as easily as possible. I was very impressed with his knowledge, customer service, and pricing. Before he left, I asked his advice on furnace maintenance and he made a trip to my basement to look things over without trying to sell a thing - yay :) I asked what he charged for a maintenance call and found he was running a special on a full maintenance visit for just under $80 until mid October - and so I booked that service right away as well. I would not hesitate to recommend Ty and Prompt Heating to anyone! This is a good guy with a really great sense of how to run a high quality, customer friendly business. Thanks!

Frequently Asked Questions:

How much does a water heater replacement cost?

Water heater replacement costs vary depending on the brand bought and the time it will take to replace it. For an accurate cost, get your free quote from one of our HVAC contractors today.

How long does a water heater last?

On average, standard water heaters last anywhere from 8-12 years, while tankless models can last up to 20. Of course, the service life depends on the specific brand and model you buy, and how your water heater is used and maintained over those years.

When should you replace a water heater?

If the tank in your water heater is over 10 years old, it is best to look into getting a replacement. Our technicians install water heaters in the greater Waukesha area.

Can a homeowner install a water heater?

You can, if you have the know-how, pull the right permit and get it inspected when you're done. If it's not done right, your house won't be up to code (in which case you'd need to pay a pro to do it before you can sell your house), and you're at risk of CO2 poisoning or worse if anything goes wrong with the venting, gas line or wiring. It's much better to hire an experienced contractor to do it for you. You'll save time, keep the manufacturer's warranty valid and gain peace of mind knowing it was done properly. All our work is backed by a 2-year workmanship warranty.

Who installs water heaters?

HVAC contractors are experienced and licensed to install water heaters. We recommend you contact a local HVAC contractor when installing your next water heater.
