For the most part, your heating system shouldn’t give you any real problems, especially if you maintain the system regularly. Regardless of the type of furnace you have, there are a number of things you can do to make sure your heating system is working at its best. That’s why it’s important to know how to troubleshoot and maintain your furnace; this could save you a considerable amount of money and keep your home or business at a comfortable temperature.
Any time your furnace is not working well, there are usually three components that are causing the problem: your heat or cold source, your thermostat or the air distribution system. If your heat isn’t coming on, the problem is at the source; this could also be a sign that there’s no power for the furnace to run properly. There’s also a chance a chance the fuel is not getting to the unit. If your furnace runs on oil or gas, it’s possible that the furnace may not be lighting. If the furnace turns on but you don’t feel any warm air, your blower or distribution system is probably not working well. A thermostat of faulty control may also keep your heating system from turning on, or this could make the furnace turn on and off over and over without your control. Regardless of the issue you find, start with the simplest tests and procedures to try to get the unit functioning well again.
Take these steps before you decide which repairs need to be done on your furnace. Be sure that the furnace is getting enough power. You can verify this by checking for a tripped circuit breaker and/or blown fuses. There are some furnaces that have a separate power entrance, and this is usually on a different panel, but close to the main entrance panel. You may also have a furnace that has a fuse mounted in the unit or on top of the unit.
If you find that a fuse has blown or the circuit is tripping over and over when you turn the furnace on, you have an issue with your electrical system. If this is the case, don’t try to fix the furnace on your own. Call a professional who is experienced with repairing HVAC units.
If you have a furnace that runs on gas and you start to smell gas in your house, don’t attempt to shut off the gas and don’t operate any of the lights on the furnace. Get out of the house right away, and make sure you leave the doors open. Call your gas company immediately and report a gas leak, and don’t go back into your home until the leak has been repaired.
Even though there are tips that you can use to keep your furnace running well, it’s also best to have your furnace maintained professionally on a yearly basis. It’s best to have your furnace serviced at the close of the heating season, since this is a time when you likely won’t need the furnace, service is usually quick, and you’re likely to get a discount. Be sure to have your air conditioner checked at this time as well.
