Boiler Repair questions, answered by experts

There are many signs and symptoms to look out for that can indicate that your HVAC system needs repair, including the following:

  • Your indoor air is uncomfortably hot or cold.

  • Your energy bills suddenly increase without explanation.

  • Your AC is blowing warm air or not blowing air at all.

  • You notice leaks around your HVAC equipment.

  • Your equipment makes unusual noises during operation.

  • You notice strange odors coming from your equipment.

  • You notice that the humidity in your home is higher than normal.

  • The thermostat no longer seems to match the actual temperature.

A poorly maintained boiler can lead to serious issues like deadly carbon monoxide poisoning, so schedule regular maintenance services. Of course, it’s also a good idea to check your carbon monoxide detectors in your home to make sure they’re working properly. Moreover, when you forget to maintain your boiler, small problems can lead to something much more serious, which will cost you more money in the long run. Repairs average around $400, while a full replacement can total over $6,000.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Yes, it is OK to turn off some radiators, and you’ll save money on heating costs if you make it a regular habit to turn your radiators off in unused rooms that don’t need heat. That said, turn them back on when you need to heat your whole home instead of cranking up the dial on the ones you haven’t closed to compensate. The latter will result in higher heating costs and more wear and tear on your system.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.
