Fast, efficient, and professional. I went to turn my heat on and realized my boiler wasn’t working. It was a Friday before a long holiday weekend but James had one of his guys there first thing Monday morning and my heat was back up and running in just a few hours! Thank you so much!! Highly recommend

Helped me make a better decision.
Went above and beyond so the work got done in a timely manor and we're very satisfied with the results.
Thank you, James & Crew.

Excellent service. Responded quickly to confirm my appointment and the work was completed quickly the same day. We will be using this company for our yearly heating maintenance.

I had a great experience working with James and his team to install our new boiler and water heater. He worked to understand our needs, gave us solid advice, and provided a competitive bid with no extras or upsells (and no BS!).  His work was very professionally done, and it was obvious that he took great pride in his work and in providing the most useful components. He also took the time to explain the work, how the equipment worked, and made sure the settings were what we we were looking for.  All in all a great experience, and we will be working with him again.

Frequently Asked Questions

Why am I running out of hot water so fast?

Sediment buildup, a failing heating element, or an undersized tank can cause your hot water to disappear quickly. We can inspect your system and recommend repair or replacement depending on what we find.

How often should I flush my water heater?

Most tank water heaters should be flushed once a year to remove sediment. Tankless systems require annual descaling to maintain performance.

Can clogged drains impact my water heater?

Yes. Poor drainage can create pressure issues that affect water flow and limit your water heater’s performance.

Does my water heater need annual maintenance?

Routine maintenance helps your system last longer, reduces breakdowns, and keeps your water bills under control.
