 Trustindex verifies that the original source of the review is Google. I would love to give them a 5 but this was a 3 day ordeal of dealing with no hot water. New hot water heater was to be installed. The 1st one was damaged out of the box. They had another delivered here. The hot water tank  worked but it wasn't warming real fast. Texh went home, unfortunately it never got hot. Of course it was a Friday, so on Mknday when are furnace was being installed, 3 technicians showed up. They immediately  diagnosed it with a bad heating element. They replaced it. At the end of the day, we had hot water and warm air. They went out of their way to correct the problem.

Frequently Asked Questions

Read through our most frequently asked questions from our customers looking to replace their old tank or tankless water heater with a new tankless water heater system.

Can I replace my current tank water heater with a tankless system?

Yes, and it’s one of the smartest upgrades you can make. We handle everything—removing your old tank, updating plumbing and venting, and installing a new high-efficiency tankless unit that delivers hot water on demand.

What’s involved in replacing an old tank-style heater with a tankless one?

We’ll disconnect and haul away your existing unit, modify connections if needed, and install the new tankless system. Most homes require minor adjustments to gas lines or electrical, and we handle that as part of the process.

Will a tankless water heater really make a difference?

Absolutely. You’ll get unlimited hot water, lower energy bills, and free up valuable space—no more giant tank taking up half your utility room.

How long does it take to switch to a tankless water heater?

A standard replacement usually takes 6–8 hours. Our team works efficiently to minimize downtime so you’re back to hot showers the same day.

Do I need to upgrade my plumbing or electrical system?

In some cases, minor upgrades are needed to meet code or ensure proper performance. We’ll review everything during your estimate and make sure you're fully prepared—no surprises.

Is it worth replacing my old tankless unit with a newer one?

If your current unit is over 10–15 years old, struggling to keep up, or frequently in need of repair, upgrading to a modern high-efficiency tankless model will save you money and headaches in the long run.
