Whether you already have a tankless water heater or your old water heater needs replaced, we will recommend tankless options that make sense for your home and water needs.

Your water heater does much more than ensuring you have hot water to take a shower in the morning. It’s used to heat water for cooking, washing your hands, and doing laundry.

Mainstream’s team of experts will come to your home, inspect your current water heater, and make recommendations on what you should do next. We’re with you every step of the way – that’s the Mainstream way!

If your water temperature is too hot or too cold, your water heater may not be doing its job. Smelly water can be a sign something is wrong with your water heater, too.

What’s the difference between a tankless water heater and a traditional one?

Tankless water heaters are just that, 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 reduces electricity or gas bill depending on the unit you install.

Excellent !

Crew was very efficient and knowledgeable. Replaced HVAC with next day service for first responders. System is working well and installed superbly. Will give it a run for a while to better judge but it is a quality name Lennox system. 10 year parts and service so expect there will be no problems. Good job!

Above & Beyond

Technician Steve, was very thorough in his investigation. Went above what I asked for, we had a black water flood and I was just asking to have the toilet and sink reinstalled. He put his camera through my sewer system to make sure that we were not going to have future issues. He made sure that I was able to see what he saw. It was educational to say the least and he was great at explaining what was in there. Feel very safe using his services and do not feel that he is taking advantage in any way. Highly recommend Steve!!

Very Professional

It was really shocking the amount of damage our pipes had and mr Johnson helped to explain what the issue was... He worked within our budget and created a couple of quotes with positive solutions. We went with the one we felt was necessary and he worked quickly getting that issue resolved. Very professional and knowledgeable.

Knowledgeable

I had Mainstream come out for an annual inspection of my hot water heater. After the inspection, it was determined that the water heater needs to be replaced. The technician, Cory, was very professional and made all of the necessary arrangements. Later the same day, Shane came out and replaced the water heater. Shane was very professional and knowledgeable. I am very pleased with the employees and the work that was completed by Mainstream.

Very Happy

We had them come out for a yearly maintenance on our water heater. They were thorough and gave good recommendations for continued maintenance and use. We also had them install a new furnace and air conditioning unit. They were very quick and efficient. All the crew members were courteous and respectful of our home. I am very happy to recommend them to others.
