Boiler Repair in Marietta, GA
Boilers are less common in Marietta than standard water heaters, but for the homes and older buildings that have them, we provide diagnosis and repair for residential boiler systems.
Signs you need Boiler Repair in Marietta
No heat or inconsistent heat output
Can point to a pressure issue, a failed circulator pump, or a thermostat problem depending on the system.
Unusual noises from the boiler
Kettling or banging sounds often indicate mineral buildup or trapped air in the system.
Visible leaking around the unit or piping
Worth addressing promptly, as boiler leaks can indicate pressure relief valve or seal issues.
A pilot light that won't stay lit
Similar to a gas water heater issue, often a thermocouple or gas valve problem.
Uneven heat between rooms or radiators
Can indicate trapped air or a circulation issue affecting how heat distributes through the system.

Why this happens in Marietta
Boiler systems are most often found in Marietta's older homes, particularly in the historic district and other pre-1970s construction, where radiant heat systems were more common than they are in newer subdivisions. A boiler original to a home from that era is now well past the point where component wear and mineral scale buildup are ordinary rather than exceptional.
How we find the actual problem
We check system pressure, the circulator pump, and, for gas units, the ignition system to identify the specific point of failure before recommending a repair, since boiler issues often have several possible causes with a similar symptom.

Boiler Repair FAQ
They're less common in newer construction, but a well-maintained boiler in an older home can still provide reliable, even heat. Whether to keep or replace one is usually a case-by-case decision based on the system's current condition.
Often called kettling, this is usually caused by mineral scale buildup on the heat exchanger or trapped air in the system, both addressable without full replacement in most cases.
Annual maintenance is a reasonable standard for most residential boilers, checking pressure, the circulator pump, and combustion components on gas units.
It's possible but a significant project involving new equipment and ductwork or radiant lines; we can discuss whether that makes sense compared to maintaining the existing boiler.
A well-sealed system shouldn't need frequent water added; if you're topping it off regularly, that usually points to a slow leak somewhere in the system worth locating rather than just continuing to add water.
Yes, boilers involve water and pressure components a furnace doesn't have, which means different maintenance points, circulator pumps, pressure relief valves, and expansion tanks specifically.

What to do while you wait
Never attempt to relieve boiler pressure yourself
The pressure relief valve is a safety component; if it's discharging or you suspect a pressure problem, shut down the system and call rather than adjusting it yourself.
Leave the area and call your gas utility if you smell gas
A gas smell near a boiler is a safety emergency independent of the boiler issue itself; treat it accordingly before addressing anything else.
Don't ignore a carbon monoxide detector alarm
Any working gas appliance, including a boiler, warrants a functioning CO detector nearby; an alarm should always be taken seriously and the area ventilated immediately.
Shut off the system if you notice active leaking
Water pooling near a boiler is worth shutting the system down for until it's assessed, both for safety and to limit water damage.
