I highly recommend Mainstream

I had the honor and privilege of having Cody Bradley come out to my house chat with me about heater water options! Cody is knowledgeable, enthusiastic, professional, and all-around a great person. From start to finish, he was about my satisfaction as a customer. His passion about the mechanics of waters heaters and plumbing made me excited to learn more and consider future options of where to invest in my home. I ended up choosing a tankless water heater option. He walked me through all the affordable financing options, which made everything painless. I’d highly recommend Cody Bradley and Mainstream Home Services.

Tankless Water Heater FAQs

Tankless water heaters are just as they sound: tankless. They heat water on-demand, whereas a traditional water heater stores gallons and gallons of hot water to use when you turn on a faucet or the shower.

Tankless saves space, saves water, and can reduce you electricity or gas bill (depending on the unit you install).

Mainstream’s team of experts will help you choose the right tankless water heater solution.

If you need a tankless water heater repaired or replaced, Mainstream is here to help. We can also make recommendations and install a new tankless water heater to replace your old, outdated traditional one.
