We carefully remove your old unit, prepare the site, and install the new system with minimal disruption to your home. A proper installation is crucial for the boiler's lifespan and efficiency, and our experienced team gets it right the first time.

Is your boiler making strange noises, leaking, failing to heat your home evenly, or not turning on at all? These are signs that your system likely requires professional attention. Boiler issues can quickly turn a comfortable home into an unlivable space, especially during cold weather.
We offer expert Boiler Repair services for all makes and models of residential boilers in the Sunset Hills area. Our technicians are highly trained to diagnose and fix a wide range of problems, from simple pressure adjustments and pilot light issues to more complex component failures like pump replacements, valve repairs, or heat exchanger problems.

When you contact us for boiler repair, we prioritize getting a technician to your home quickly to identify the issue and provide a transparent explanation of the necessary repairs.

Boiler Maintenance and Tune-Ups
Regular maintenance is the key to ensuring your boiler operates reliably, efficiently, and safely year after year. Without routine care, minor issues can escalate into expensive repairs, and your system may consume more energy than necessary. Annual boiler tune-ups are recommended by manufacturers and energy experts alike.
Our comprehensive boiler maintenance services in Sunset Hills help prevent unexpected breakdowns and prolong the life of your heating system. During a tune-up, our technician will perform a thorough inspection and cleaning of critical components, check pressure levels, test safety controls, examine for leaks or corrosion, and ensure the system is running optimally. This preventative service helps identify potential problems before they cause a system failure, improves energy efficiency, and ensures safe operation by checking for issues like carbon monoxide leaks.
Participating in our Maintenance Plan offers additional benefits, including regular service reminders, priority scheduling, and potential discounts on parts and services. Investing in annual boiler maintenance is investing in your home's comfort and peace of mind.

Understanding Your Boiler: Signs You Need Service
Being aware of the warning signs your boiler might exhibit can help you address potential issues early, preventing minor problems from becoming costly emergencies. Keep an eye out for these common indicators that it's time to schedule professional boiler service in Sunset Hills:
- Unusual Noises: Gurgling, bubbling, hissing, or banging (often called "kettling") can indicate air in the system, low pressure, or sediment buildup in the heat exchanger.
- Pilot Light Issues: If your pilot light keeps going out or has changed color (should be blue, not yellow or orange), it could signal a problem with the gas supply or a faulty thermocouple.
- Loss of Pressure: If your boiler pressure gauge consistently shows low pressure, there might be a leak in the system or an issue with the expansion vessel.
- Leaking: Puddles or drips around the boiler indicate a leak, which could be from a faulty seal, valve, or pipework. Leaks can cause corrosion and system damage.
- No Heat or Inconsistent Heat: If radiators aren't heating up, the boiler isn't firing, or some areas of your home are cold while others are warm, it points to a heating distribution issue or a problem with the boiler itself.
- Frequent Cycling: If your boiler is turning on and off more frequently than usual, it could be short cycling, potentially due to an improperly sized system, thermostat issues, or internal component problems.
- Rising Energy Bills: A sudden or gradual increase in your heating costs without a change in usage patterns can indicate that your boiler is losing efficiency and working harder to heat your home.
If you notice any of these signs, it's best to contact an experienced boiler technician promptly. Addressing issues early can often prevent more extensive and expensive damage down the line.

Frequently Asked Questions About Boilers
How long do residential boilers typically last?
With proper installation and regular maintenance, residential boilers can last anywhere from 15 to 30 years, depending on the type of boiler and the quality of care it receives. Annual tune-ups are crucial for achieving maximum lifespan.
What's the difference between a standard and a condensing boiler?
Standard boilers vent hot gases directly, losing heat. Condensing boilers capture some of the heat from these gases by condensing the water vapor they contain, making them significantly more energy-efficient (typically 90%+ AFUE compared to 80-83% for older standard boilers).
Is it better to repair or replace my old boiler?
This depends on the age of your boiler, the cost of the repair, and its current efficiency. If your boiler is old, frequently breaking down, and repairs are costly, replacement with a new, high-efficiency unit is often more cost-effective in the long run due to reduced energy bills and fewer future repair expenses. A technician can help you weigh the options based on your specific situation.
What does boiler maintenance include?
A professional boiler tune-up typically includes checking and cleaning the burner, heat exchanger, igniter/pilot light, controls, safety switches, and venting system. The technician will also check system pressure, look for leaks, test efficiency, and ensure all components are operating correctly and safely. This is similar to the process described in our Maintenance Plan.
