- What We Do
Our Boiler Solutions
Some boilers just need one part. Others have given all they’ve got and are due for a high-efficiency replacement. We do both, and the work usually lands in one of the four areas below.
Boiler Repair
When a boiler won’t fire, keeps losing pressure, or heats unevenly, the cause is often a circulator problem, a failed thermostat, or a leaking heat exchanger. We track down the cause, explain it, and quote the fix before we start. The last step is always a check that the system is running safely.
Boiler Installation
Putting a boiler into a new build, or swapping out an old system, starts with sizing it right for your home. We install high-efficiency boilers and work with both gas and oil models, and our licensed technicians handle the gas piping.
Boiler Replacement
If fixing the old boiler would cost more than about half of what a new one does, replacing it is usually the smarter spend. We remove the old boiler and install the new system. Considering a high-efficiency model? Ask us about Mass Save incentives and we’ll help you see what you may qualify for.
Boiler Maintenance
The emergencies we get in January usually started as something minor back in October. A boiler tune-up is your chance to catch it, with an inspection of the burners, heat exchanger, pressures, and safety controls. The price is $89.
- Know the Signs
Warning Signs Your Boiler Needs Attention
Boilers tend to complain for a while before they quit. Listen early and you can dodge a freezing night and a larger repair bill.
Something doesn't seem right?
Have a professional inspect your system before a small issue turns into a breakdown.
Boiler Repair
The boiler is running, but the water is lukewarm or the house never really warms up. Typical causes are a dead circulator pump, air trapped in the radiation, or a blocked flue pipe. A technician can test the system and check combustion to pin down which one it is.
Low Water Pressure
Pressure that keeps dropping, a gauge acting strangely, or a boiler that keeps resetting itself usually means a leak or a failing automatic fill valve. The fix starts with checking the pressure vessel, finding any leaks, and replacing whatever is defective.
Strange Noises
Kettling, gurgling, and banging usually come from mineral buildup, air in the lines, or a pump on its way out. Depending on the cause, the fix may be bleeding the air, flushing out sediment, or replacing a worn pump.
Frequent Cycling
Newer boilers flash an error code or fall into short cycles. Often the cause is a bad sensor, a dirty flame sensor, or a thermostat problem. We read the code, run diagnostics, and clean or replace whichever part is failing.
