Does Your Furnace Need Heating and AC Repair If It’s Producing Uncharacteristic Sounds? | Lewisville, TX

It can prove frightening whenever you turn on that furnace only to hear a loud and scary sound. You should never ignore that sound. Modern furnaces are engineered or designed to run quietly. Whenever you hear your furnace sounding like a monster within a closet, it means that there is a problem with the furnace.

Depending on the noise the furnace produces, the issue with the furnace might be either mild or severe. Regardless, you should have a heating and AC repair professional inspect the unit to diagnose and fix the issue. The noises produced by the furnace might be a telltale sign of a more significant problem that might prove dangerous to your Lewisville, TX home or HVAC unit should you ignore them.

Using their years of experience and training, the heating and air conditioning repair technician can diagnose and fix the issue. The most common furnace noises include high-pitched whistling, booming or groaning, rattling or shaking, humming or buzzing, and scrapping or screeching. Below are the main reasons why your furnace is making those uncharacteristic noises.

The Transformer

The transformer’s role is to convert the required energy to ensure the system runs at the proper voltage. It doesn’t have any moving parts. However, it will start producing an electrical buzzing sound when the transformer starts to fail. Whenever the transformer makes noise, it is time to have a heating and AC repair professional replace the hardware. Unfortunately, when the transformer fails, you’ll be unable to use the furnace.

Further, if the transformer box becomes loose, it might start rattling and also create a humming noise. If this happens when you’ve just installed a new furnace, it might be possible that you have to tighten its mount up a little bit more. Though you might fix this issue yourself, it is better to enlist the help of an HVAC professional. This is because DIY heating and AC repairs might worsen the problem; not to forget, you expose yourself to a risk of electrocution.

The Blower Motor

The blower motor within your furnace ensures that warm air is circulating in your Lewisville, TX home. However, if the blower motor isn’t properly or sufficiently lubricated, it might start scaping and produce a buzzing or humming noise. At times, these sounds are a telltale sign of a motor failure. Whenever the motor becomes clogged with debris and dust, there can arise an amperage issue that kills the motor. To avert the amperage issues, the heating and AC repair professionals advise homeowners to change their air filters more often. Whenever you hear buzzing noises or begin a heating cycle, you must seek professional help from an HVAC technician.

Loose Ductwork or Equipment

As time passes, the equipment might loosen and vibrate against each other. Whenever this happens, you should have an HVAC technician tighten the nuts, screws, bolts, seams, joints, or loose equipment. If loose, these can damage the furnace. The loose joints and seams might prove to be a nasty problem within the ductwork as it causes inefficiency in maintaining your indoor temperatures. If the air ducts are accessible, you may be able to tighten the duct work using a mastic sealant and foil tape.

If you can’t find the noise source or cannot access the air ducts, enlist the help of a heating and AC repair technician. The professional will secure the equipment to ensure that there aren’t any vibrating pieces or air leaks. Whenever the vibration goes on, some ductwork areas might collapse. You might also get high energy utility bills at the end of the month because of wasted energy.

Dirty Burner or Furnace Filter

A high-pitched whistling noise from your furnace is among the scariest sounds you might hear. Whenever you notice that the unit is producing this sound, your furnace has a blockage, and the air cannot flow past the dust, debris, and first. For an HVAC professional, a dirty filter is among the easiest furnace issues to fix since they will only have to replace the filter.

However, if your HVAC unit has a permanent filter, the professional will clean it. However, removing the air filter is better if you cannot afford one to avoid overworking the HVAC unit. The heating and AC repair technician in Lewisville, TX, will recommend that you clean or replace the air filters after about 1-3 months to avert similar issues. If the furnace’s burner is dirty, the HVAC unit will make a booming sound whenever the furnace starts up.

However, if it sounds scary, then that is a sign of trouble. A dirty burner delays the ignition, allowing gas to accumulate within the combustion chamber. This buildup of gasses within the combustion chamber could create an explosion, causing severe damage to the furnace. If the HVAC unit’s burners are dirty, ensure that you enlist the help of a heating and AC repair professional to repair it. Never ignore this sign because it might severely damage your HVAC unit.

The Capacitor

It isn’t uncommon to notice a dull hum when the furnace runs. However, if the humming is loud or your furnace isn’t responding to the settings on the thermostat, the dull humming sound might indicate an electrical problem. In such a case, your furnace might turn on and make noise but won’t run. The capacitor stores electrical power to boost the furnace when it begins a heating cycle.

However, the buzzing noise might be caused by a failed capacitor if the HVAC unit’s motor isn’t working. Instead of having to guess what the issue is, why not enlist the services of a professional heating and AC repair technician. They will not only inspect the HVAC but also diagnose the problem and permanently fix it.

A furnace doesn’t make noises without reason. Hence, you must act fast whenever it produces an uncharacteristic sound. By doing this, you’ll be able to determine the cause of the issue and have an HVAC professional come over and fix it.

However, homeowners are encouraged to have regular heating and air conditioning repairs, inspections, and maintenance. Do you need a furnace inspection or maintenance?
