Even the best furnace is going to have its off days. From lack of maintenance and age to unexpected mechanical problems, furnace problems are a fact of life for homeowners.
In many cases, a malfunction in your furnace isn’t a reason to panic. Some of the most common things that may go wrong are usually fairly easy to fix. Here’s a quick look at some of the most common issues that’ll have you calling for furnace repair.
1. Clogged Filters
It’s easy to forget about your furnace’s filter, which is why issues from neglected furnace filters make the top of the list.
The air filter in your furnace is responsible for trapping dirt, debris, and other particulates that float through the air in your home. If you forget to change the filter, and it becomes so full it restricts airflow, you may have some problems.
When air can’t pass through properly, it forces your HVAC system to work harder than it usually does to push the air through your filter. In addition to using up more power to do the same job, which reflects on your increased power bill, this extra strain takes a toll on the parts that make up your furnace. That typically necessitates (easily preventable) furnace repairs.
2. Thermostat Problems
The thermostat has a big job. It’s responsible for monitoring the temperature in your home and telling the furnace when to turn on and shut off. If it stops working, it can make things pretty uncomfortable.
A common problem with thermostats is loose wiring. If the wires that run from the thermostat to the furnace come loose, it breaks the connection and prohibits communication. That means the blower fan, heating elements, and burners may all be affected. In these situations, your furnace may get stuck off or on. In either case, it’s a problem that requires professional furnace repair.
3. Ignition Issues
Though more prevalent in gas furnaces than electric, problems with the ignition systems are common. These issues are often the result of damaged furnace ignitors. A simple fix for an HVAC professional, but not something you should try to fix at home.
4. Worn Down Parts
While furnaces boast an impressively long lifespan of 15 to 20 years when properly maintained, the individual parts themselves may not have such a long life. Over time various parts will wear down. Moving parts tend to suffer the most wear, such as fan blades, belts, and motors.
5. Noises
If your furnace is suddenly making weird sounds that it didn’t make before, that’s a good indication you need furnace repair. A noisy furnace is telling you there’s something that requires attention. Some of the most common sounds you may hear are:
- Whistling
- Rattling
- Screeching
- Loud humming
- Banging
If you hear any of these sounds, it’s time to call in an expert.
