Common Signs of Furnace Malfunction

Posted by

Furnaces have long been one of the most popular options for property owners looking to provide their families with comfortable indoor temperatures during the coldest months of the year. They are able to function efficiently even during serious cold snaps and tend to have a relatively long lifespan provided they are adequately maintained. That doesn’t mean they’ll last forever, though, which is why homeowners should be on the lookout for these common furnace problems.

Strange Sounds

Homeowners that notice strange sounds coming from their furnaces should call a repair technician as soon as possible. There are a variety of different underlying mechanical issues that can cause this problem, so it will be impossible to determine whether or not the unit can be repaired without first consulting a qualified professional.

Inefficient Operation

As heating units begin to age, they start operating inefficiently due to normal wear and tear. Homeowners who have been experiencing an increasingly frequent need for repairs may want to consider replacing their older, worn-out units with newer, more efficient models.

No or Low Heat Production

If the unit is not providing adequate heat anything from a simple thermostat issue to a much more complex pump issue or blower problem could be to blame. The first step to take toward resolving this problem is to contact a repair technician who can isolate the mechanical malfunction causing it. From there, homeowners will have to decide whether they want to invest money into repairs or simply purchase a new unit.

Cycling Problems

Most of the time when furnaces cycle between their on and off states frequently it is due to simple clogged filters. Homeowners themselves can change these filters out to see if it improves the problem. If it doesn’t, there might be an airflow issue or an equipment malfunction that prevents the unit’s flame from burning.

Lighting and Ignition Problems

If a furnace’s automatic ignition or pilot system is not functioning well it can cause trouble. Most of the time these issues can be resolved through scheduling a routine maintenance visit to remove any dust and debris present in the system. A dedicated repair technician will be able to perform this maintenance work and determine whether or not there are other underlying problems that may affect the unit’s operation.
