Signs That Your Furnance Needs An HVAC Technician To Repair It

The last thing you want is to find yourself without any heat in your home during the coldest part of the winter. Therefore, it is important to make sure that you are well aware of the following signs that your furnace is in trouble and needs to be repaired by a professional HVAC technician. To help you with this, you may want to review the following points.

Banging Sounds

Your furnace should run smoothly without a lot of sounds coming from it. Therefore, if you are starting to notice that it is putting off a lot of banging sounds, you will want to get it looked into. There could be a belt that is sticking, wearing thin, or even possibly coming detached from the parts holding it on. Then again, it could be that the motor fan is starting to lock in place and the banging sound is the result of that.

Pilot Light Is Yellow

If you have a natural gas or propane furnace, then you have a pilot light that needs to burn a strong and steady blue color. If it is burning yellow, then you have a serious problem and need to shut your furnace off immediately. Do not turn it back on until a professional HVAC contractor has diagnosed the problem and fixed it for you. The reason for this is that the yellow flame of the pilot light indicates that it is producing carbon monoxide, which is an odorless and deadly gas.

You Have To Keep Relighting The Pilot Light

Even if your pilot light is burning blue, it can still be a problem for you if it keeps going out. When the pilot light is out, you are not able to get any heat into the home. The reason the pilot light is continuously going out could be that the ignition is faulty. It could also be that the pilot light mechanism is dirty and the build up of dirt and grime is causing the light to keep going off.

You Smell Gas

You could never smell gas coming from your furnace. If you do, then it is important to turn off the furnace and evacuate the home so that no one because injured from the toxic fumes. Once the home has aired out and an HVAC technician has resolved the problem, you will be able to resume using the furnace. The cause of the gas fumes could be the result of a faulty exhaust system.

With those few signs in mind, you should have no trouble making sure that you are able to recognize the need for a skilled heating and air conditioning repair technician right away.
