When properly installed, inspected and operated by a HVAC specialist, furnaces generally operate without incident. But a time may come when you need to know the difference between daily repair of furnace and repair of emergency furnace.
Living in the Atlanta area, you appreciate the fact that our winters are mild in comparison with areas like SYRACUSE, NEW YORK or DULUTH, MINNESOTA. Our coldest month is in January with average high at the 50° and lows at 30°. However even with mild winters no one ever wants their heat to fail when you need it the most. A cold home is not comfortable.
When it comes to your furnace many things could be filed as ‘maintenance’ most home owners can easily attend to. Then there are problems which need more attention immediately from a licensed professional.
2. Furnace is Making Unusual and Loud Noises
Furnaces make noise, some are common sounds that you can detect as the furnace operates are tiny little clicks or hums. But, if your furnace is noisier than normal or you start making a sound you’ve never heard before, it usually indicates that your furnace is not functioning correctly and it may be time to talk to your heating contractor about some maintenance and repairs.
(1) I Hear a Scratching Sound:
If your furnace begins to make scratching noises, particularly the sound of steel scraping metal, something is likely to be loose and may need repairs. Your blower wheel may have a problem. Your heater will not be able to heat your home adequately if your blower wheel is malfunctioning. If it is a blower wheel issue a trained professional can address this issue and repair your furnace.
(2) I Hear a ‘POP’ or a ‘BANG’:
There are a common reasons why you may hear noisy banging or
cracking from your furnace:
Dirty furnace burners – This can cause a delay in ignition when dirt collects on the furnace burners, which can cause the gas to build up. You’ll hear a loud pop or boom when the burners actually fire. Such small explosions could destroy your furnace and break your heat exchanger, which could be an expensive fix.
When you hear this kind of sound, contact a licensed HVAC company right away. Waiting around for this to self-correct itself could result in costly repairs.
Expanding and contracting air ducts – The ducts will expand and contract when the furnace is turned on and off if your home has steel air ducts. When you start hearing a popping noise, the ducts may have a defect that may need to be patched, such as undersized ducts, closed doors, flimsy ducts, or a blocked air filter. Again don’t wait contact a licensed HVAC professional.
(3) I Hear a ‘Squealing Noise’:
High-pitched squealing sound that mean a number of things, but it is usually due to a component which needs repair or fixing. Worn out pieces like a frayed blower belt or a malfunctioning blower motor can make such sounds and can require further major repairs to your furnace.
Don’t wait, remember a furnace is mechanical, the components will break down and eventually stop working. They will not self-correct. When you start hearing those odd noises, don’t ignore them
