When the cold season comes, your furnace becomes one of the most valuable appliances in your home. Everyone wants to be in a nicely warmed house during the cold days. And since most people stay indoors longer during winter, it's good to keep your furnace in good working condition. 

The worst thing you may want to think about is a faulty furnace during winter. However, if your furnace isn't working for one reason or another, seek help from a furnace repair technician. Here's how you know it's time to repair your furnace.

1. It Doesn't Start

Every furnace works more efficiently when it's new. But as time goes, its efficiency reduces. If your furnace is old, it may get a little cranky. The unit may even fail to start when you want to warm your home. A furnace that won't start-up shows you need to get a professional to repair it. 

Your furnace could also need repairs if it usually kicks in after starting it several times. Wiring is usually the leading cause of this problem. You need a professional to check whether the unit's wiring is disconnected or loose. A damaged thermostat could also cause the problem. Whichever the case, it's good to get it repaired in good time.

2. It Doesn't Warm Your House

You know you have a problem to fix if the furnace is on, but the house is cold. Sometimes the thermostat is to blame for this problem. If it's not set properly, the furnace won't warm the house. This means you may have to put on several layers of clothing to keep your body warm. 

However, this won't solve the problem. If the unit is running without heating the house, you will pay high energy bills and enjoy no comfort. Get a furnace repair technician to check why the unit doesn't heat your house. They will identify the failing components and repair them.

3. It Doesn't Receive Power

A furnace that isn't receiving power is defective. Even if the furnace is new, you need a technician to find out why it doesn't receive power. The switch or even circuit breaker might be the problem. But if they are in good shape and the furnace doesn't get power, you have a bigger problem. The unit's wiring could be faulty. If you don't fix the problem quickly, the unit may eventually release sparks that could cause fire damage.

Furnace problems are diverse. Even if the furnace is designed to heat your home for a longer period, it may develop issues before its useful life is over. However, a competent furnace repair technician will repair your faulty furnace without causing damage to your home or injuries to anyone.
