If you're noticing issues like a lack of heat, strange noises, leaks, or inconsistent temperatures, it's time to call in the experts. Our technicians are skilled at diagnosing and repairing a wide variety of boiler problems in Clayton homes.
Common boiler issues we frequently address include:
- No Heat: This could be due to issues with the pilot light, igniter, thermostat, or other internal components.
- Uneven Heating: Rooms feeling warmer or colder than others can indicate circulation problems or zone control issues.
- Leaking or Dripping: Leaks are serious and can be caused by pressure problems, faulty valves, or damaged pipes or seals.
- Strange Noises: Banging, gurgling, or whistling sounds can signal issues like mineral buildup (kettling), air in the system, or pump problems.
- Low Boiler Pressure: This can prevent the system from circulating hot water properly, leading to insufficient heat.
- Pilot Light Issues: If your pilot light keeps going out, there could be a draft problem or a faulty thermocouple.
When you call Hely for boiler repair in Clayton, our process begins with a thorough inspection to accurately diagnose the root cause of the problem.

Boiler Installation & Replacement in Clayton
While repairs can extend the life of your boiler, there comes a time when replacement is the most cost-effective and reliable solution. This is often the case for older, inefficient systems or those facing frequent, costly breakdowns. Installing a new boiler can significantly improve your home's comfort, reduce energy bills, and provide greater peace of mind.
Signs it might be time to consider boiler replacement:
- Your boiler is over 15-20 years old.
- You're facing increasingly frequent or expensive repairs.
- Your energy bills are consistently high, suggesting low efficiency.
- Your home isn't heating evenly or struggles to reach temperature.
- You notice signs of rust or corrosion on the unit or pipes.
When replacing your boiler in Clayton, choosing the right system is crucial. We specialize in residential gas boilers, a common and efficient heating source for homes in the area. Understanding efficiency ratings like AFUE (Annual Fuel Utilization Efficiency) is key. An 80% AFUE rating means 80% of the fuel consumed is converted into heat for your home, while the remaining 20% is lost through the chimney. Modern, high-efficiency boilers can achieve AFUE ratings of 90% or higher, leading to significant energy savings and reduced heating costs over time.
The boiler installation process with Hely Heating and Air Conditioning is designed to be as smooth and non-disruptive as possible. We assess your home's heating needs, recommend the appropriate boiler type and size for optimal performance, and handle the removal of your old unit and the precise installation of the new one. We feature Goodman equipment, a trusted name in home comfort, known for its reliability. New Goodman installations are backed by strong warranties, including a valuable 5-year labor warranty, providing added protection and peace of mind.
Boiler Maintenance
Regular maintenance is the key to ensuring your boiler operates efficiently, reliably, and safely year after year. Just like a car, your heating system benefits from routine check-ups and tune-ups. Neglecting maintenance can lead to reduced efficiency, increased risk of breakdowns, and a shorter lifespan for your unit.
Our comprehensive boiler tune-up includes vital checks and cleaning procedures designed to identify potential problems early and optimize performance. This typically involves:
- Inspecting and cleaning key components such as the burner, heat exchanger, and ignition system.
- Checking pressure and temperature settings.
- Examining pipes, valves, and pumps for any signs of leaks or wear.
- Testing safety controls to ensure they are functioning correctly.
- Checking for proper ventilation and combustion.
The benefits of regular boiler maintenance include:
- Increased Efficiency: A clean, well-tuned boiler uses less fuel to produce the same amount of heat, saving you money on energy bills.
- Reduced Risk of Breakdowns: Catching small issues during maintenance can prevent them from escalating into costly repairs later.
- Extended Equipment Lifespan: Proper care helps your boiler last longer, delaying the need for premature replacement.
- Improved Safety: Ensuring proper combustion and ventilation is crucial for the safety of your home and family.
To make maintenance convenient and ensure your system receives the care it needs, consider our Maintenance Plan. A service agreement provides scheduled tune-ups and other benefits to keep your system in peak condition.
