Common Boiler Problems We Repair

Boilers are complex systems, and faults can arise in many different components. Our technicians are experienced in diagnosing and repairing all of the following issues and more:

  • No heat or hot water
  • Boiler not igniting or failing to fire
  • Strange banging, whistling, or gurgling noises (kettling)
  • Pressure loss or pressure that is too high
  • Pilot light going out repeatedly
  • Thermostat or controls not responding
  • Leaking or dripping from the boiler
  • Radiators not heating evenly or staying cold
  • Frozen condensate pipes
  • Error codes displayed on the boiler panel
  • Circulator pump failure
  • Heat exchanger issues

If you're not sure what the problem is, don't worry — we'll diagnose it. Our technicians arrive prepared with the tools and common replacement parts needed to complete most repairs in a single visit.

Boiler Repair vs. Boiler Replacement

Not every boiler problem requires a full replacement, but some situations make replacement the smarter long-term investment. As a full-service HVAC company, Constant Home Comfort is uniquely positioned to give you an honest assessment — we'll never push you toward a replacement you don't need, and we'll never drag out repairs on a system that has reached the end of its useful life.

If your boiler is more than 15 years old, has required repeated repairs in recent years, or has suffered a significant component failure, our technician may recommend exploring replacement options. We carry and install a wide range of boilers from trusted manufacturers and can walk you through available rebates and financing programs that may significantly reduce your upfront costs.
