Homeowners can avoid the inconvenience of going without heat by recognizing the signs that a heating repair is needed. Furnaces typically do not break down without exhibiting warning signs. A good way to reduce the chances of a breakdown occurring is to get routine maintenance. If a heating system breaks down during the cold season, there are likely to be a lot of service calls. This is why it is ideal to get systems inspected in advance. The following points identify signs that heating repair services are needed.

Strange Odors

If a furnace has not been used for a while, a burnt odor might be emitted. This is usually dust burning in the system, and it should dissipate shortly. A burnt odor that persists could be a sign of a serious issue such as an electrical problem, which could lead to a furnace failure. Heating repair services might not be an option in this case. Ignoring odors could also cause a furnace fire. Gas leaks also produce a peculiar odor that many individuals describe as smelling like sulfur. This odor is caused by an additive to the natural gas that is called mercaptan.

Broken Thermostat

Thermostats are small units, but they are important for efficient heating. A non-working thermostat is a sign that an emergency heating repair is needed. However, it is also possible for a thermostat to produce the wrong temperature of heat. A heating repair contractor can determine if a thermostat can be repaired or whether it needs to be replaced.

Cold Spots

Heating systems should blow warm air in all areas of a home unless there are closed vents or rooms that do not have vents. Homeowners who experience this phenomenon should check their vents to ensure they are open. If they are, it is a sign that heating repair services are needed. If repairs are delayed, it will negatively impact efficiency, which will likely mean higher energy costs.

Strange Sounds

A properly working furnace will not be noisy. Screeching, banging, or clanking sounds are signs that something is amiss and that heating repair services are needed. These sounds are usually caused by loose or broken parts. Ignoring them may lead to damage to the furnace. Emergency heating repairs reduce the chances of a complete furnace failure. 

An HVAC contractor is a good resource to use to learn more about heating repair services. They can troubleshoot and repair systems to ensure that they are safe to operate. If there are frequent breakdowns, they can determine what is causing them. Sometimes older systems break down because it is time for an upgrade.
