Boiler Repair and Services in Troy

A heating system’s boiler enables your unit to recognize and automatically respond to inside and outside temperature fluctuations in order to cultivate a comfortable atmosphere in a home or business. Often times boilers will experience malfunctions during the winter months as they start up again after an extended period of inactivity.

Fortunately, the top-notch HVAC technicians at Birmingham Plumbing Heating & Cooling in Troy have the skills required to take care of all issues with your heating system, including any malfunctions within your unit’s boiler. Our team is available 24/7 to address emergency heating needs, so you’ll never have to worry about handling a crisis alone.

Most Common Boiler Problems

Our HVAC contractors can assist with boiler problems of all shapes and sizes, including:
· Lack of hot water or heating: Possible reasons involve broken airlocks, diaphragms, impaired valves, faulty thermostats, and lowering water levels. If you notice this issue, check to see if the cause is due to a problem with your thermostat or boiler pressure. If the issue is due to an impairment within your airlock, valve, or diaphragm, a professional will need to install a replacement part.
· Leakage: The reason for a leaking boiler depends solely on the location of the puncture. However, the most prevalent cause is an impaired internal part, like a pressure valve or pump seal. A malfunctioning pump seal will require a replacement part, whereas a leak stemming from the pressure valve might indicate that your boiler pressure is excessively high.
· Low Pressure: If your boiler pressure becomes too low, your heating unit might not be working correctly. Low pressure can be a result of a water leak, faulty pressure relief valve, or impaired radiators.
· Kettling: If you hear an odd noise resembling the sound of a kettle heating, deposits such as sediment and sludge, might have accumulated in your boiler’s heat exchanger. This buildup restricts water flow, prompting it to steam, boil, and produce a “kettling” noise. This issue will strain your boiler and may reduce its lifespan. An expert technician will be able to flush your system out and eliminate the buildup to restore your unit.

If you notice any of these issues with your boiler, contact us at Birmingham Plumbing Heating & Cooling so we can send a qualified HVAC technician to diagnose the issue and make repairs as soon as possible.

Does replacing or servicing a residential gas boiler require a mechanical permit in the City of Troy?
Yes. According to the City of Troy Building Department and the Michigan Mechanical Code, replacing or making major modifications to a residential hydronic heating boiler requires a pulled mechanical permit and an official inspection. This inspection verifies that the unit meets strict state and local standards for gas line sizing, combustion air intake, pressure-relief discharge piping, and ASME CSD-1 safety control compliance.
Hydronic boilers use auto-fill valves connected directly to your municipal fresh water supply. Because the water circulating inside a boiler heating loop is stagnant and often treated with anti-freeze, rust inhibitors, or chemical descalers, it poses a contamination hazard. The City of Troy mandates an approved backflow prevention assembly (such as a dual-check valve with atmospheric vent) on the fill line to prevent non-potable boiler fluid from siphoning back into your drinking water supply.
A Low-Water Cut-Off (LWCO) is a crucial safety mechanism that constantly monitors the water level inside your boiler vessel. If the water level drops too low due to a pipe leak, air purge, or failing expansion tank, the LWCO instantly shuts off the gas burner. Operating a dry boiler can crack the heavy cast-iron heat exchanger, cause catastrophic thermal stress failures, or trigger an intense dry-fire safety hazard.
While boilers operate in closed-loop systems, frequent top-offs from untreated, mineral-rich Troy municipal or well water introduce calcium and magnesium into the system. Over time, these minerals settle in the boiler’s heat exchanger, creating “kettling” noises, reduced thermal efficiency, and localized hot spots. Annual system flushes, air separator checks, and adding hydronic water conditioners prevent mineral scaling and internal pipe corrosion.
Classic cast-iron boilers are built like tanks and last 20 to 30+ years, but they typically operate at 80% to 85% AFUE. Modern wall-hung condensing boilers achieve up to 95%+ AFUE by extracting extra heat from water vapor in flue gases. Upgrading reduces winter heating bills significantly, but converting a classic Troy home requires verifying that your existing radiator loop temperatures align with condensing operation and installing dedicated side-wall PVC intake and exhaust venting.
