What We Repair & Service

Boiler issues don’t always announce themselves loudly. Uneven heating, unfamiliar banging or gurgling sounds, visible leaks, or a sudden spike in energy bills are all signs your system needs attention. Our technicians diagnose the root cause first and walk you through what we find before any repair begins.

We’re a Navien-certified contractor, trained and authorized to install and service Navien high-efficiency boiler equipment to the manufacturer’s own standards. High-efficiency boilers can reach an annual fuel utilization efficiency (AFUE, a measure of how much fuel the system converts to usable heat) of 90% or more, compared to as low as 60% on older equipment. That difference can show up on your energy bill over time.

Beyond the boiler unit itself, our services extend to the full hydronic heating system that circulates heated water through your home:

  • Baseboard and radiant heat repairs: We bleed lines, check thermostats, and resolve cold spots that make rooms uncomfortable
  • Gas piping and appliance hookups: We manage gas line connections with strict safety protocols and perform pressure testing on all gas work
  • Boiler pressure and temperature controls: We inspect and service the safety mechanisms that keep your system operating within safe parameters
