What type of maintenance does a boiler need?
Your boiler typically needs a thorough annual inspection and cleaning of its components, like the burner and heat exchanger. A professional will also check for any leaks or corrosion, test safety controls, and verify the system's pressure is correct. They’ll also ensure all electrical connections are secure and that the system is operating efficiently. At the end of the visit, your pro can give you a summary of their work and let you know if any repairs are needed. This regular service can help ensure it runs safely and efficiently, which may prevent costly future breakdowns and extend its lifespan.
How often should a boiler be serviced?
It’s best to have your boiler serviced once a year, ideally during the late summer or early fall. An annual check-up helps ensure your system is running safely and efficiently, which can prevent costly breakdowns during cold weather. This regular maintenance can also help keep your energy bills down and extend the lifespan of your boiler. For typical lifespan references, see InterNACHI’s life expectancy chart .
What are signs that I need to hire a boiler maintenance professional?
Common signs that indicate it’s time to hire a boiler maintenance company include:
Strange noises. If you hear gurgling, whistling, or banging sounds, it could mean there’s trapped air or a buildup of limescale inside the system that needs attention.
Leaks and drips. Any water pooling around your boiler is a clear sign that a component may be failing. It’s best to get this checked out right away to prevent water damage.
Inconsistent heating. When your radiators aren’t heating up evenly, or if some stay cold altogether, it often points to a circulation problem or sludge in the system that needs professional cleaning.
An unreliable pilot light. A pilot light that frequently goes out or burns with a yellow flame instead of a crisp blue one can indicate a ventilation or gas supply issue.
Higher energy bills. If your heating costs have gone up without a change in your usage, your boiler might be losing efficiency and working harder than it should.
Professional boiler maintenance companies can help resolve these issues before they become worse.
What questions should I ask before hiring boiler maintenance pros?
Before hiring boiler maintenance companies, be sure to ask your pro these questions:
Are you licensed, bonded, and insured to work on boilers in my area?
What specific checks and tasks are included in your standard maintenance service?
Do you have experience with my specific type and brand of boiler?
How do you structure your pricing — is it a flat fee for maintenance or an hourly rate?
Do you offer a warranty on your labor or any parts you might need to replace?
What is your availability for emergency service if my boiler fails unexpectedly?
Can you provide a few references from recent customers?
How long do boiler maintenance companies take to complete a service?
Typically, it will take one to two hours for a professional to complete boiler maintenance. There are a few factors that may impact how long it takes. For example:
Boiler type and age: Older or more complex boiler systems can take longer to inspect and service thoroughly.
Condition of the unit: If the boiler is very dirty or hasn't been serviced in a while, it will require more time to clean.
Accessibility: A pro may need more time if the boiler is located in a cramped or hard-to-reach space.
Necessary repairs: If the technician finds any parts that need to be repaired or replaced, the job will take longer than a standard service.
System flushing: A full system flush to remove sludge and debris can add a few hours to the total service time.
Remember: The timeline for your project will vary depending on many factors. Always ask your pro to provide an estimate.
What steps should I take before my pro arrives to perform boiler maintenance?
Take these steps before your boiler maintenance pro arrives to ensure a safe and efficient appointment:
Clear the area around the boiler. Your technician will need at least three feet of clear space to work safely and access all components.
Note any specific issues. If you’ve noticed strange noises, leaks, or uneven heating, write them down to share with your pro.
Secure pets and keep children away. For everyone’s safety, please make sure pets and small children are kept out of the work area during the appointment.
Check if the system should be turned off. Ask your pro if they’d like you to turn the boiler off an hour or two beforehand so it’s cool enough to work on.
Have previous service records handy. If you have records from past maintenance or repairs, they can give your pro valuable insight into your system’s history.
