As is the case with HVAC systems, your furnace will need repairs once in a while. The tricky part is knowing that your furnace is faulty and needs repairs. That said, compiled are a few signs you need furnace repair services. 

Furnace Blowing Cold Air

A furnace is of no use if it can't warm your home. So, if your furnace is blowing cold air or your space can't seem to get adequate warmth, chances are that your furnace is faulty. This is a sign you can't miss during the cold season. 

Your furnace might be producing cold air due to a malfunctioning motor or a problem with the heat exchanger and pilot light. These are problems that an experienced technician can rectify within a few minutes.

High Heating Bills

A faulty or aging furnace will have you paying higher energy bills than usual. If your energy consumption has gone up but your furnace isn't that old, there is a likelihood that some parts are faulty.

A furnace that isn't performing well will run continuously in an attempt to keep your room's temperature in check. You should call an HVAC expert to check the air filters and any other component that could be interfering with your furnace's performance.

Water Leaks

Water pooling around your furnace is never a good sign. In fact, you should act immediately after noticing water puddles around your furnace. Failure to do so could cost so much in repair costs.

Water leaks around furnaces are mostly caused by a condensation leak, clogged filter, or a heat exchanger problem. Once you notice water leaks, shut off the furnace and call an HVAC professional to correct the problem.

Unusual Noises

Most furnaces will make minor humming and popping sounds, but they are all normal noises. However, if you hear loud, strange sounds coming from your furnace, it's most likely failing. Some strange noises you should look out for are:

• Squealing noises
• Thumping noises
• Banging noises
• Loud popping noises
• Metal scrapping
• Rumbling sounds
• Loud humming sounds

These noises can either be caused by:

• Loose blower belt
• Unlubricated shaft bearing
• Malfunctioning blower motor
• Unbalanced blower wheel
• Faulty fan or capacitor
• Faulty burner

Call for furnace repairs immediately you hear any of the above noises. Ignoring them might cause more damage than you could expect. 

Furnace failure is a common occurrence, and you should be on the watch out for any of the above warning signs. The trick is catching these problems early before they escalate.
