Have you been having trouble with your furnace? Has your furnace stopped working? These are the top 5 problems (and solutions) that you may experience with your furnace at home!
Now that the cold weather is starting to set you, you may start to have some issues with your furnace. Thankfully, many of these issues have easy and simple fixes to them. The first step you should take is seeing if your HVAC system has power; if not you may want to try and flip the switch on your breaker to get it working again. If the power is not the issue, there are some other things you can check out for yourself, before calling a technician.

Solution: If you notice that your heat isn’t coming on, the first thing you may want to do is check the batteries. You want to change the batteries if necessary, and while you’re at it maybe give your thermostat a good dusting inside!

The last thing you can do is try to reboot your thermostat. Keep your thermostat set to heat but turn the temperature down to about 15º Celsius (approximately 60º Fahrenheit). Then, turn the breaker switch off for 30 seconds and turn it back on. If that doesn’t work, you may want to call an expert!
#2 PROBLEM: Unit not turning on

To ensue that your furnace is working properly and not on overdrive, make sure to change your filter once every 1-2 months. Here’s how you can: Turn your furnace off, find the proper filter for your furnace, remove the old filter in your furnace, replace it with the new one, and turn the unit back on.

Solution: Do you notice that your furnace clicks as though it is about to turn on, but then goes silent and doesn’t end up starting?

In order to fix it you must start by turning off the gas to your furnace. After that you are to remove the front panel and find the igniter or ignition sensor, which is typically located near the burners. Check to see if the igniter or ignition sensor is dirty. If it is, remove the ignition sensor with a screwdriver and give it a good clean, being extra careful that you do not cause any damage to it. Then put it back exactly as you found it and replace the panel before turning the gas back on. If you do not feel comfortable doing this on your own, make sure to call an expert technician!
#5 PROBLEM: Furnace has blown a fuse
