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.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

If you have multiple radiators, start by bleeding a first-floor radiator that is farthest from the boiler. Work your way toward the boiler on the first floor before moving to the next floor, where you’ll again start by bleeding the radiator farthest from the boiler. Continue this pattern for radiators on each floor until they’ve all been bled.

Modern boilers average around 20 years of use before failing, with some hitting 25 to 30 years. Older boilers, however, can last up to 50 years because they are often made from ultra-durable cast iron. Newer models are made from steel alloy and related components, which are great for withstanding high pressure levels and hot temperatures but offer a slightly lower life span.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
