What A Tankless Water Heater Replacement Includes

  • The sizing visit. How much hot water runs at once, the gas supply and the venting, so the new unit keeps up in winter.
  • One recommendation. The water heater we would put in, why it suits the house, and what it costs to run.
  • The permit. Pulled and closed out by us, not left with you.
  • The old one gone. Drained, disconnected, removed and disposed of.
  • Venting, relief valve and connections. Checked or replaced so the new unit runs safely.
  • Filled and tested. Lit or powered up, hot water run at the taps, and checked for leaks before we go.

Your Free Water Heater Quote In Novi

We come to the house, look at what you have now and work out what actually suits it. There is no charge for the visit and no obligation at the end of it.

  • We look at the whole job. The household, the bathrooms and appliances, the gas or electric supply, the venting and the water heater there now.
  • We ask what is not working for you. Whether the hot water runs out, how old the current one is, whether it has leaked, and how long you plan to be in the house.
  • We recommend the water heater that suits it. Tankless or tank, the size and the fuel, in plain language, with what it costs to run.
  • You get it in writing. The water heater, the permit, the venting and connections, the old one taken away and the start up, all in one price.

Already Have A Quote?

Bring it. We come out, look at what has been quoted for your house and give you ours for the same work, with everything it includes written down. That is our free second opinion, and you compare the two before you decide.

Financing Available

The question people ask before they book a quote. The technician makes the call on site, and we price both so you can see the difference.

What you are looking atRepairReplace
How old it isUnder ten years, a repair is usually the cheaper answerPast fifteen to twenty years, a new unit usually makes more sense
What failedA sensor, the igniter, a flow switch, or scale that needs flushingA leaking heat exchanger, or a failed control board on an older unit
Hot waterSteady again once it is descaled or repairedStill running cold mid shower after a descale and a repair
Repair against newUnder a third of the replacement priceMore than half the replacement price on an older unit
Error codesOne code with a clear causeThe same codes coming back after every repair

I noticed that my furnace was not working around 3pm.  I called and a service person was there a little after 4 and took less than an hour to fix it.  I am very happy with the service.

From the phone call to schedule the service needed to the completion, all contacts were professional and timely. Prices appropriate. I have been a Moore customer since 2014 and would not change...every contact through the years has been great!

Questions We Get Asked About Tankless Water Heater Replacement In Novi

How Long Does A Tankless Water Heater Last?

Often twenty years when it is descaled on schedule. Past fifteen, or with a leaking heat exchanger, a new unit usually makes more sense than another repair.

Does A New Tankless Water Heater Need A New Gas Line?

Not always. When a tankless unit replaces a tankless unit, the gas line and the venting are often already right. We check both on the visit and tell you if anything needs to change.

Should I Go Back To A Tank Water Heater?

Only if a tank suits the household better. We price a tankless and a tank replacement side by side so you can compare.

Do You Handle The Permit For Tankless Water Heater Replacement?

Yes. We pull it and close it out.

Is The Tankless Water Heater Quote Really Free?

Yes, including the visit and the written quote at the end of it. There is no obligation.

Can I Pay For New Equipment Over Time?

Yes. We offer payment plans through GreenSky and Michigan Saves on new equipment, and you can apply before the work is scheduled.
