How To Know If Your Furnace Is In Trouble

Not many people can say that they want their house to be freezing cold during the winter and therefore, need to keep their furnace in tip top shape at all times. To help you make sure that you're never going to be without heat for your home, you will want to check out the following signs that your furnace could very well be in a lot of trouble. This way, you will be able to call in a skilled HVAC technician, such as Laroc Refrigeration-Metal Division, before it is too late.

Too Many Banging Sounds

It is normal to hear a slight humming sound when your furnace first kicks on. However, you should not have to listen to a lot of banging sounds. If the sound is so loud that is seems as though someone would be down in your basement physically hitting the side of the furnace, you need to call for immediate help. This could be anything from a broken belt to a fan motor that is locking in place. If you have a natural gas furnace, the banging sound could be a build up of natural gas that sits in the furnace until it reaches the pilot light. Either way, this is not a problem that you are going to want to ignore.

The Pilot Light Is Burning Yellow

A yellow pilot light in your natural gas furnace is a sign of trouble, as the flame should be a bright blue. Any color other than blue lets you know that the furnace is omitting carbon monoxide. This is a colorless and odorless gas, which can be deadly. Should you find that the pilot light is the wrong color, you will need to evacuate the home immediately and call for emergency services. Allow emergency personnel to come in and turn off your furnace so that the carbon monoxide is no longer entering your home. You can then call in a professional HVAC contractor to diagnose the problem and fix it for you

You Can't Get The Temperature Right 

If it seems as though your home is never able to reach the desired temperature, it could be a problem with the furnace. Of course, you might want to first check to make sure that the wall thermostat is still functioning properly. After all, a replacement thermostat is a much cheaper expense. If it turns out that the thermostat is not the problem, then you will want to have an HVAC technician inspect the furnace for you.

With those few clues in mind, you should have little trouble determining when it is the best time to call in the professional heating specialist. The sooner you make that call, the less likely it is that you are going to have to deal with any major heating setbacks in your home.
