A typical HVAC system contains a furnace, AC condenser, air handler, and ducts. All of these parts need regular maintenance or your home may not stay at a comfortable temperature. Plus, when there's a lack of maintenance, there's an increased risk that parts will break down. The blower in the air handler is one part that's essential to the proper functioning of an HVAC system because that's what moves air through your house. Here's a look at what can go wrong with a blower and repairs that might be needed.

The Purpose Of An HVAC Blower

The blower is like a fan that's inside the air handler. It works with other parts of the HVAC to create airflow. Air from the house is pulled into the air handler, treated, and then circulated through your house. When the blower isn't working to capacity, there may be low airflow coming out of your registers. If the blower breaks down, then your HVAC system won't function at all.

Changing The Filter Protects The Blower

The filter that you change every month or so protects the blower from getting dirty and gummed up. This is why changing the filter on schedule is so important. When the parts of the blower get dirty enough, the blower may shut itself down if it overheats. Besides keeping a clean filter in place, the blower should also be cleaned regularly by an HVAC technician during a preventative maintenance call. If the blower is kept clean and in good shape, then it will work better and have a longer life.

What Can Go Wrong With A Blower?

The blower is like a fan with a cage and motor. There are multiple parts that can malfunction inside the motor and assembly. The bearings might wear out, or there could be an electrical problem. Sometimes, when the blower is going bad, it will make unusual noises to alert you. Other times, a sign of a bad blower could be when your HVAC shuts on and off frequently and has trouble meeting the setting on the thermostat. Since the blower is a hardworking part in the air handler, you should suspect it as the cause of trouble you may be having. If you think your blower is not working properly, then call an HVAC company like Soco Air Conditioning to make repairs. The motor may need to be taken apart, so blower repairs usually require a professional's knowledge and experience.

Keep in mind that the blower is just one small part of an HVAC system, even though it's an important one. When your HVAC isn't working like it usually does, it's a good idea to call an HVAC technician to take a look at it so repairs can be made before further damage is done by running the unit when it's malfunctioning.
