About geothermal · Service my system

Your system's second-favorite phone number

Whoever installed it, we will keep it running. WaterFurnace factory-trained techs, every service class the factory offers, and diagnostics that find the fault before the invoice grows.

Protecting the investment

Trained on it, stocked for it, honest about it

We are proud to service existing WaterFurnace equipment and have taken every service class the factory provides. A unit with three moving parts does not need much, but what it needs, it should get from someone who knows the machine cold.

Not a WaterFurnace? Bring it anyway. A large share of our service calls are systems from other brands, often ones another company installed and stopped answering the phone about.

  • All geothermal brands repaired and maintained
  • Top-class diagnostics: find it fast, fix it once
  • Annual maintenance plans with a 24/7 emergency line
  • Loop testing when you suspect the underground half

Question about your system, a strange noise, or just want a second opinion on a proposal you got elsewhere? Write or call, a geothermal designer answers both.
