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."

How much does a new water heater cost?
AO Smith tank water heaters installed start at $2,575 for a 40-gallon, $2,755 for a 50-gallon and $5,259 for a 75-gallon. Navien tankless installations start at $5,999. Every home is different, so your exact flat-rate price is quoted upfront before any work starts. Gas or electric, venting, location and code updates can change the price.
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 20 to 30 years with a yearly flush. 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.
