2. Warm Air

The temperatures during the summer months can quickly climb. If you have an AC in place, you and your family can sleep comfortably and remain cool in the afternoons.

Warm vents may be a sign that the AC needs repair or replacement. The compressor may be too old, and it’s not cooling the air around you correctly, or the entire system does not have enough refrigerant. You should also consider a duct problem where the attic may be pulling in air from the outside rather than from the compressor. The experts can pinpoint and check your ducts to make sure that there are no problems with them, and you can trust them to make the right diagnosis of the problem.

3. Unpleasant Odors Coming Out

The HVAC system’s primary goal is to make the whole family comfortable regardless of the weather outside. However, there are times when you turn on the AC, smells are coming out of it, and this can make the family sick.  Unpleasant odors are some of the first signs that your AC needs thorough cleaning and maintenance. There may be mold growing inside it, or electrical issues may burn some components inside the appliance.

Musty smells can be signs of fungi and mold. The spores that the AC will circulate can trigger allergic attacks, making the whole family sick. If there’s a burning smell, then the electrical wires’ insulation may be the problem, and you need to contact a professional as soon as possible.

4. Unusual Sounds

It’s normal for an AC system to have a humming sound while it’s on. However, you should be alert if you start hearing some sounds that are unpleasant to the ears and this is a sign of ineffective usage. Read more on how to use you’re AC system more effectively on this site here.

If you have a central or a split-type, you may want to check how the outdoor unit is sounding. If there are unusual sounds, then your technician will be the one to pinpoint the problem. Some sounds to look out for are the following:

-Clicking as the Outdoor Unit is Running. This may mean obstruction in the fans. The striking object should be removed immediately before it can damage other inside components of the unit.

-Clicking Sounds but Outdoor Units Doesn’t Turn On. The clicking sounds may indicate that there’s an electrical problem in the unit. The system components are having difficulties, and short circuits may be present.

-Gurgling or Bubbling. If you hear a gurgling sound, then there may be an issue with the condensate drain line. If this is the only problem that you have, then it may not lead to bigger ones. However, you still need to get a technician to check if refrigerant leaks are resulting in bigger headaches in the future.

-Clanging and Banging Sounds. The noise is an indication that an object is stuck on the fans. The obstruction is hitting the components inside, and the fan mounts may loosen up. If this is the case, the loose mounts may wobble, causing it to hit the cage protection around the unit.

-Squealing of the Indoor Units. Squealing noises are indicators that there’s a problem with the fan belt. The sound may be present one day and gone the next. However, when the belt gets damaged and eventually breaks, your AC may stop working altogether. It’s better to get your appliance checked when you hear weird noises before they turn into larger problems.

-Screeching Metal. If you hear the sounds of screeching metal, this may mean a problem with the outdoor unit. The metal sounds are present because of the fan motor bearings that require a fan replacement.

-Screaming or High-Pitch Hisses. The sound may come from the compressor, which indicates that there’s a build-up in the system. This can be dangerous, and for everyone’s safety, it’s better to switch off your AC. Don’t turn the entire unit on until your technician in Lewisville arrives.

5. Thermostat is not Functioning

The thermostat sets the temperature, and it’s often considered the brain of many HVAC systems. The components will function according to the thermostat’s temperature, and the device will determine for how long the home should be cooled before it can be switched into fan mode to save energy.

The thermostat may continuously measure and re-evaluate the instructions according to home temperature. However, when you notice that your appliance keeps shutting on and off frequently, it may be a sign that you should consider repair or replacements. You can check with a technician for more information about the things that you need to do about your AC unit.
