Boiler Repair questions, answered by experts

At minimum, you should plan to have your HVAC system serviced once per year, usually leading into either the summer or winter before it sees heavy usage. If you live in a particularly cold, hot, or humid climate, consider servicing your HVAC system twice per year—once in the spring and once in the fall—to keep it running efficiently and prevent it from going down in the high-demand seasons. You can also schedule one-off services if you notice issues like uneven heating or cooling, poor performance, or strange noises from your equipment.

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.

If you hire a professional to replace your gas furnace’s thermocouple, you’ll usually pay between $150 and $250. Since thermocouples often fail due to a lack of maintenance, you may be able to avoid—or at least delay—a thermocouple replacement by taking good care of your furnace. This means scheduling annual furnace inspections, changing the filters at least once per season, and cleaning the burners occasionally.

Most repairs take 2-6 hours, but extensive repairs or part replacements may require a full day or more, depending on availability.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.
