Top 5 Furnace Problems and Solutions
Is your furnace shutting off by itself? Does it give off a burning scent? If you’re experiencing any of these issues, then you might be in need of a furnace repair. However, just because you’re experiencing a problem with your HVAC doesn’t always warrant the need for a professional. In some cases, you can fix the issue yourself.
Here are the top five furnace problems and their solutions.
The Air Filter is Dirty
A dirty air filter sounds harmless enough, right? It is if it’s properly maintained. However, a dirty air filter can cause a lot of other issues. Some of these issues include an increase in utility bills, producing a burning smell and making you more vulnerable to illness.
The solution to this is very simple; replace the air filter. How long before you have to change it depends on the size of the filter. One to two-inch filters need to be replaced every three months, four-inch filters need to be replaced every six months and five-inch filters need to be replaced every year.
The Furnace Won’t Turn On
Another common furnace issue is when it won’t come on. If your furnace isn’t turning on, make sure the emergency shutoff switch isn’t off. In some cases, it might be switched off, which completely disconnects the power to the furnace. Other potential reasons why your furnace won’t turn on include faulty circuit breakers and a malfunctioning pilot light. In cases like this, you should contact a HVAC professional for assistance.
The Furnace Won’t Ignite
When a furnace isn’t igniting, it may seem like it’s about to turn on, but then suddenly turn off. There are a few reasons as to why this happens. It could be a problem with your power source, thermostat or air filter.
Other times, it could be because the ignition sensor isn’t working. If this is the case, you’ll have to cut the gas off to your furnace. After that, you’ll need to unscrew the sensor and clean it. If that doesn’t solve the problem, then you’ll have to call a heating service for help.
The Thermostat is Malfunctioning
Your furnace heavily depends on your thermostat and won’t work properly if its not working properly. The most basic solution for a faulty thermostat is changing the batteries and cleaning the inside of it.
The location of your thermostat also plays a role in its functionality. If it’s in an area where there’s too much sunlight, it could impact the readings. To fix this, reboot and relocate your thermostat in a cooler area. If the problem persists, a heating service company can help.
A Fuse is Out
Although rare, a furnace can potentially have a fuse blow out, which is the result of an electrical issue. However, this is one of those problems where you need to call a furnace repair company to fix. They have the proper training and expertise to handle these kinds of situations. Fixing it yourself is also an option, but it’s very dangerous if you lack the experience.
