Experts typically charge a minimum amount when they make service calls, so a fairly simple fix can help homeowners avoid wasting money. Some repairs are easy to perform, and troubleshooting helps owners learn more about their heating systems.
Although many problems require professional help to resolve, knowing the nature of the problem helps experts know what to bring, which speeds up the fix and leads to lower repair bills. Repair experts may be able to diagnose the problem over the phone and bring an appropriate replacement part if the owner can determine the nature of the problem.
Thermostat problems can cause a heating system to stop working. Many common problems are due to homeowners failing to understand how their thermostats work and setting them incorrectly, so it's worth reading through the operation manual and setting the thermostat to a setting that should cause the system to fire. If the thermostat doesn't turn on at all, replacement is generally simple.
If the side of the boiler or furnace warms but the fans won't blow, users can make sure their fan motors are connected and check if their fan is obstructed. If the heating unit does not generate heat, it may be worth checking the front control panel. Newer models often produce an error code if the unit stops functioning, and this code can indicate what has failed.
