What to Expect During Gas Boiler Maintenance Services for Your Locust Valley, NY Home

A gas boiler is an efficient and reliable way to heat your Locust Valley, NY home. From generating the heat that warms your house to create the hot water that comes out of your faucets, your boiler is constantly running. With so much use, the appliance is going to experience wear and tear, and eventually, it could start to break down. In order to keep it in tip-top condition, regular gas boiler maintenance is an absolute must. But if you’ve never had your boiler inspected, you might be wondering what to expect. Below, you’ll find a general overview of the gas boiler maintenance process so that you can prepare.

An Initial Inspection

To begin, a reputable professional will perform an initial inspection of your Locust Valley, NY gas boiler. They’ll check all of the components and will take four key measurements, including the efficiency of the system, the temperature of the chimney, carbon monoxide levels, and carbon dioxide levels. Additional measurements may also be taken. The goal of an inspection is to gain an initial understanding of the overall condition of your gas boiler and how it’s working.

A Complete Cleaning

After performing an initial inspection and gaining an understanding of how your system is functioning, a technician from a reputable Nassau County boiler company will clean your system. They’ll clean any residual residue, dirt, and debris that may become trapped inside the boiler, as well as on the external components of the system.

A Thorough Check

Once the cleaning has been completed, the next step in the gas boiler maintenance process is a thorough check of all working components. The minimum air and gas input will be checked, the overall condition of the tank will be assessed, the pilot light will be checked, and the valves will be inspected, for example. If you have a condensing boiler, the technician will also check the drainage system for condensates, and if the unit is wall-mounted, the heat exchanger will be checked, too.


If the technician finds that there are any issues with your Locust Valley, NY gas boiler, they’ll make any necessary repairs. This may include tightening loose valves or replacing damaged parts. Of course, a technician from a reputable Nassau County company will let you know about any boiler repairs that may be needed before the repairs are actually made. Once any issues are corrected, the chimney will be swept.

Final Checks and Adjustments

After your gas boiler has been inspected and cleaned, and once any repairs have been made, the professional will take the same measurements that were taken at the beginning of the boiler service; the efficiency, the chimney temperature, the carbon monoxide levels, and the carbon dioxide levels. If it’s determined that any of the results do not fall within the legal limits then the technician will make adjustments to ensure that the measurements are within the legal limits.

Completion and Review

After your gas boiler has been thoroughly inspected, cleaned, repaired (if necessary), and the final assessments and adjustments (if needed) have been made, the technician will either issue a new date tag or will write down the necessary information on the existing data tag. The data tag should contain all of the key information that pertains to the appliance, as well as the date that it was serviced; they’ll initiate the data tag, too. This tag is important, as it lets you keep tabs of when you last had your gas boiler serviced so that you know when you need to schedule your next gas boiler maintenance appointment; additionally, it will provide the technician who performs your next service with key information.
