Noises coming from your HVAC system don’t automatically mean you need to scramble for your phone to call a heating and AC repair service. Depending on the model of the system, they can just be part and parcel of how the system functions. After all, your HVAC system isn’t the only electric appliance that makes noise. Your television, computer and washing machine all do too.

That said, some noises are certainly strange and if you are in Fort Worth, TX, you’ll want to have us check out your system if you start noticing them. These are generally sounds apart from jets firing on. A system that’s experiencing some issues can make a myriad of noises. These are some of the most common.

Rattling or Vibrating

At the earliest sign of a rattling or vibrating noise, you’ll need to call a heating and AC repair service. That sound means trouble and, more specifically, it points to something that’s loose inside either the furnace or the air ducts. Rattling or vibrating noises hardly ever go from not there to being unbearably loud the next instant. They typically start off tame and subtle and slowly progress to being noticeable.

This is why it’s always important to check if the HVAC system in your Fort Worth, TX, home isn’t making any weird sounds from time to time. That can help you catch them and call a heating and AC repair service to fix things before they get more severe.

If the loose part is a screw or a section of the air duct, that can mean real trouble down the line. The same can be said if it’s the outdoor fan motor, which is usually about to fail when it starts making noises like that. Getting the problem fixed as soon as possible can mean you don’t lose years of your system’s functionality.


A whistling sound might not necessarily point problems of the same severity as you’d expect with rattling or vibrating sound, but it’s certainly something to watch out for. This sound will sound like a whistling wind, and it’s typically much more noticeable when there’s a strong wind.

As you might have guessed, it’s probably because there’s a hole in your ductwork. The size of the hole tends to correspond with how loud the noise, so a bigger hole means you’ll have to deal with the annoyance of a louder sound.

More than the annoyance, you might also find that your house is much colder, even when you turn the heating all the way up. In most cases, it also means you’ll have a much less efficient system. That’s especially troublesome if you’re in the middle of a freezing winter or a sweltering summer.

To get rid of this problem, call a heating and AC repair service to fix your HVAC system. That will get rid of the annoying whistling song while helping to restore comfort to your Fort Worth, TX, home.

If the whistling sound is high-pitched, that can mean there’s a refrigerant leak, which should be sorted out right away.


This can be one of the most intolerable sounds on the list. It can also point to a severe problem with your HVAC system that needs to be checked by a heating and AC repair service. If you’ve ever been around pigs, the sound is quite comparable. It can be heard from all over the house, too, in most cases.

A squealing sound is a telltale sign for a problem with one, two or all of these three components: a motor, belt or bearing. In other cases, it can also mean there’s a problem with the blower wheel and its housing. When you first hear the sound, it might very well not point to anything urgent or hazardous.

Ignore it without calling a heating and AC repair service, however, and you might have to deal with expensive repairs down the line. The best thing to do is to have a professional check your system when you first to suspect that there might be a problem.


This is the sound that should have you reaching the phone and dialing a heating and AC repair service’s number as soon as you hear it. An explosion-like sound doesn’t just to point to problems with the HVAC system, it also means there might a potentially dangerous problem.

A booming furnace is more often than not the result of a delayed gas ignition, which is something that always requires urgent action. A delayed gas ignition itself means that gas is constantly building up within your system. In a functioning system, the gas should be burning straight away.

That means all the booming you are hearing is a literal explosion, showing the true severity of the problem. The quicker you can call a heating and AC repair service, the better.


If there are clicking noises coming from the HVAC system in your Fort Worth, TX, home, it might be time to call the heating and AC repair service. This usually points to electrical problems, which only get worse with time. As there are many electrical parts in your HVAC system, you’re better off calling a professional so they can find the exact defective part.

The clicking noises may also be a sign of a failing thermostat or faulty control. Before you panic, you should remember that it’s normal to hear clicking noises when you’re either switching on or turning off the system. Anything too loud or too sustained, however, can point to a serious problem.

Furnace noises, depending on which one you’re hearing, can mean you either have a slightly annoying problem or something more dangerous. While the system itself can be durable and well built, ignoring these problems is one way to invite heavy repair and replacement costs down the line.

Something else you will want to avoid is diagnosing these problems yourself. The best way to go about this is to call One Hour Air Conditioning and Heating for your heating and AC repair service, ensuring the restoration of both safety and comfort in your Fort Worth, TX, home.
