How To Know If Your Heating System Needs The Help Of An HVAC Contractor
It is very important to make sure that you are on the lookout for some signs that your heating system is in need of professional help. The sooner you spot a problem and call to have it resolved by an expert, the less likely it is that you are going to experience a total loss of heat in your home. Here are some of the following signs that you need the assistance of an HVAC contractor.
The Heat Is Turning Off Sooner Than It Should
If you have started to notice that it does not seem as though the furnace is running as long as it should before it shuts off, you will want to find out why. It could be that the thermostat is simply old and has started to malfunction. If you see that the desired temperature that is set on there is never reached, you will want to go ahead and replace the thermostat. This could be something that you can do on your own, or you can hire a contractor to do it for you. If that is not the problem, you will want an HVAC professional take a close look at the furnace for you.
The Pilot Light Is No Longer Blue
The pilot light of a natural gas or propane furnace should be blue. If it is yellow, then it is time to shut it off and call for an expert to evaluate the furnace. When furnaces start to have carbon monoxide leaks, you will notice that the flame color will change. Do not turn the furnace back on, even if you cannot smell anything out of the ordinary. This is because carbon monoxide is odorless and it is deadly. Even if this means that you have to find another place to stay, that is what you need to do. In such situations, you might want to specifically look for an emergency HVAC technician since you will have been displaced from your home because it is too dangerous to remain there.
You Hear Strange Knocking Sounds
You might hear some noises when your furnace turns on, but it should not be startling. In fact, it should be the same noise that you always hear and that might sometimes fade into the background because you are so used to it. Therefore, if you are suddenly noticing that there is a new sound coming from the furnace, you will want to have it checked out by a reputable HVAC contractor.
