What Is a Boiler Service?
A boiler service is a professional inspection, cleaning, and performance check of your heating system. A certified technician examines key components, tests safety controls, and ensures everything runs efficiently.
What does a boiler service include? A standard boiler service typically includes:
- Checking for gas or carbon monoxide leaks
- Inspecting the heat exchanger and burners
- Testing the thermostat and safety devices
- Cleaning internal parts if needed
- Verifying proper pressure and ventilation
- Identifying worn parts or potential failures
This isn’t just a quick look. It’s a full system check to make sure your boiler operates safely and reliably throughout the year.
Do You Need a Boiler Service Every Year?
Yes, especially if you want to avoid expensive repairs, keep your energy bills low, and extend the life of your system. Annual servicing is recommended by manufacturers and often required to keep your warranty valid. Even if your boiler seems to be working fine, internal components can wear down, collect dust, or become inefficient without showing clear signs.
For example, if your home in Olympia sees heavy boiler use during the colder months, waiting more than a year between services increases the risk of mid-winter breakdowns when technicians are busiest. Regular servicing helps catch small issues early, like a faulty pressure valve or buildup in the heat exchanger, before they snowball into major failures.
You’re also protecting your safety. Gas boilers that aren’t properly maintained can leak carbon monoxide, which is odorless and dangerous. A yearly inspection ensures your boiler is properly vented and operating safely.
What Happens During a Boiler Service?
During a boiler service, a licensed HVAC technician performs a full inspection and tune-up of your system. The goal is to make sure your boiler is working efficiently, safely, and reliably.
At Sunset Air, a typical service starts with a visual inspection to check for obvious signs of wear, corrosion, or leaks. From there, the technician removes the boiler casing to examine internal components like the heat exchanger, burner, and fan.
They’ll clean out any dust or debris that could affect performance, check gas pressure and flow, and make sure the flue is clear and venting properly. Safety devices, including carbon monoxide sensors and pressure relief valves, are tested to ensure they’re functioning correctly. They’ll also check the thermostat, look for error codes, and verify that water pressure and temperature controls are within the recommended range.
If you’ve noticed small issues like strange noises, reduced heating, or inconsistent hot water, a boiler service is the time to bring them up. These could be signs of limescale buildup or worn parts, which are easier and cheaper to fix before they cause a breakdown. The technician will document any concerns and let you know if repairs are needed now or should be monitored over time.
Who Services a Boiler?
Boiler servicing should always be done by a licensed HVAC professional, but not all HVAC companies have the same level of expertise. When choosing a boiler services provider, look for these qualifications:
- Are they licensed and insured in Washington?
Confirm they hold a valid contractor’s license and carry liability insurance to protect your home.
- Do they specialize in boiler systems?
Ask if the technician has hands-on experience with your specific boiler type—whether it’s gas, electric, or a high-efficiency condensing model.
- Can they explain what’s included in the service?
A trustworthy company will walk you through a detailed service checklist. Be cautious of vague “inspections” or “tune-ups” without specifics.
- Do they provide clear, upfront pricing?
You should receive a flat rate for the service and written estimates for any additional repairs before work begins.
- What do their local reviews say?
Check for consistent feedback on professionalism, punctuality, and how thoroughly they perform the job.
Red Flags to Avoid When Choosing a Boiler Service Provider in Washington
Not every HVAC company is qualified to work on boilers. Before you book, watch for these common red flags that could signal inexperience, poor service, or potential safety risks:
- No license or proof of insurance
- Vague or generic service descriptions
- Little to no boiler experience
- Pushy repair recommendations
- Unclear or shifting pricing
- Few or poor customer reviews
- No written checklist or service report
How Much Does a Boiler Service Cost?
In Olympia, WA, a standard boiler service typically costs between $150 and $300, depending on your system type and service provider. High-efficiency or older boilers may require more time and care, which can push the price toward the higher end.
Some companies offer seasonal discounts or maintenance plans that reduce the annual cost. These plans may also include priority service or discounts on future repairs. It’s worth considering if your boiler is 10+ years old or heavily used.
What’s important is value, not just price. A cheap, rushed service that misses key checks can lead to costly repairs later. A thorough service by an experienced technician saves money long term by preventing breakdowns and improving efficiency.
