Boilers will need maintenance, repairs and replacements, and a professional HVAC company will be able to provide you with an accurate assessment in this regard. They will offer you their honest opinion regarding your boiler’s condition and will tell you how best to proceed.

Certain signs will indicate that you are in need of boiler services, so if you ever notice any of the following, make sure you contact a professional HVAC technician right away:

Expensive Heating Bills

If you find that you are seeing higher-than-normal heating bills, it may be a sign that you need boiler repair or maintenance. Depending on the situation, you may even need a replacement boiler, so don’t ignore this aspect because it may not be just the result of rising fuel prices, and there may be more to this problem.

Long Wait Times to Heat Your Building

Inefficient boilers will take a long time to work, so it will be a while before your building is warmed up. If you notice that it is taking longer and longer to warm up your building every time you turn the boiler on, you are definitely in need of boiler services.

Unusual Sounds

Deposits can accumulate on boilers over time, and this will lead to hissing sounds. Maintenance is a must at this point, and in most cases, this step will be enough, although if you fail to address this problem in a timely manner, you may have to deal with repairs or a replacement instead.

The Smell of Gas

If you ever smell gas, contact an HVAC technician right away because you require immediate boiler services. Shut off your boiler and exit the building as this will avoid the creation of sparks. Once you’re outside, call for help.

Old Age

Old boilers can cause you some headaches, and if a boiler is more than ten years old, it may be costing you more money than you realize. It’s likely that failure is on the way, and it would be wise to seek emergency boiler services.


This is very problematic, so if you ever notice a leak, this issue needs to be resolved right away; otherwise, you can run into water damage and mould issues. Leaks are never a good thing, so even if it’s small and doesn’t seem serious, you still need to contact a technician.

Old Filters

This component needs to be changed regularly because it will become clogged over time. If you cannot remember when you last changed your filters, your boiler should be inspected.
