Hard water and your new tank
According to the City of Tulsa, Tulsa water averages 5.2 to 8.2 grains per gallon of hardness depending on the treatment plant. That is why we add a yearly maintenance reminder to our system when we install your tank.
Repair before replace, explained by Michael
We don't start with a sale. "A lot of times you can just repair them versus replacing, which is cheaper." When it does need replacing, Michael is straight about why our techs don't push it: "If your water heater can be repaired or needs to be replaced, technician gets paid the same."

A replacement already waiting under warranty
The homeowner on this Broken Arrow job had already arranged a 75-gallon warranty replacement through Home Depot. Casey and Jared handled the transport: they took the failed Rheem to the store, collected the AO Smith and brought it back to install. New stainless flex connectors, water hammer arrestors and a ProPress shutoff with adapters completed the connections. Read the warranty replacement story for what our crew handled alongside the homeowner's store arrangement.
A narrow closet still needed the supporting parts
The Glenpool 50-gallon gas replacement sat beside a furnace in a narrow utility closet. We worked around overhead venting, water piping and the gas connection. Along with the new tank, the work included a drip pan, an expansion tank, water hammer arrestors, stainless flexible water connectors and a main shutoff valve. The gas side received a new flex connector and drip leg. We removed and disposed of the old tank. See the Glenpool closet installation.
Straight Answers
What are your operating hours for water heater services?
For water heater installations, our hours are Open 24 hours Monday–Saturday · Closed Sunday. Call or text (918) 891-1737 to arrange your visit and discuss the installation.
How do you price your work?
Before your heater installation begins, we quote the flat-rate amount upfront. That pricing applies throughout the Tulsa metro, and a home inside our service area does not have a separate trip fee added. You know the price before work starts.
Do you offer upfront pricing?
The water-heater price stated at your door is the price for the work. There are no hidden fees waiting to be added to that quoted amount.
What areas do you service?
We serve Tulsa, Bixby, Broken Arrow, Owasso, Catoosa, Glenpool, and surrounding communities with offices in Tulsa and Bixby.
Can you bring older water heater setups up to code during installation?
Yes, our crew installs necessary components like expansion tanks, hammer arrestors, and proper flex connectors to bring your water heater setup up to code.
How much does a new water heater cost?
Installed AO Smith tank pricing starts at $2,575 for the 40-gallon size. The starting figures are $2,755 for a 50-gallon tank and $5,259 for a 75-gallon tank. A Navien tankless installation starts at $5,999. Those are starting prices, not a quote for every house: gas versus electric, the venting, the heater's location and any code updates can affect your installation cost. We give your home's exact flat-rate price upfront before starting any work.
Can you replace my water heater the same day?
Yes. We can usually do a same-day replacement for a standard 40- or 50-gallon tank, and we haul away the old one.
What code updates come with a water heater replacement?
Usually a new ball valve, water hammer arrestors, an expansion tank, a drip pan under the tank so a leak doesn't flood the house, and a drip leg on the gas line.
What warranty comes with an AO Smith water heater?
AO Smith tanks come with a standard six-year warranty. You can upgrade to a ten-year warranty by having a second anode rod installed, which helps protect the tank.
How do I make my water heater last longer?
Flush it once a year and change the anode rod every two to three years. We add a yearly maintenance reminder to our system when we install your tank.
What if I buy my own water heater?
We can install it, but a tank you supply doesn't get the tank warranty you get when we provide it. You get a limited warranty on the parts we use.
Should I get a tank or tankless water heater?
A tank costs less up front and lasts about 10 to 15 years. A Navien tankless costs more, gives endless hot water and can last 25+ years with a stainless heat exchanger (15 to 20 with copper) with a yearly flush, typical rather than guaranteed. We'll walk you through both.
Do your techs earn more if I buy a new water heater?
No. Our technicians are paid hourly, not on commission, so they get paid the same whether your water heater is repaired or replaced.
Can installation include collecting a warranty replacement tank?
Yes; on the Broken Arrow job, our crew took the failed tank to Home Depot and brought the warranty replacement back for installation.
Was the old tank removed on the Glenpool 50-gallon replacement?
Yes; that installation included removing and disposing of the old tank.
