Is the House Haunted, or Does the HVAC System Need Repairs?

Three Signs That the AC System Needs Repairs 

The AC might work perfectly fine, keeping the home cool and maintaining a consistent temperature. However, some troubling signs could point to a deeper issue that needs immediate attention. One day, the AC could be fine, and the next, it could be out of commission entirely. 

When a homeowner notices any of the following signs, they should consider contacting an AC professional:

Loud Sounds Coming from the Unit 

soundsIt’s not unusual for the AC to hum while it’s on. However, certain sounds warrant professional help, such as: 
  • Screeching. No, that’s not a ghoul trapped in the AC system. It’s likely a problem with the motor fan or belt. 
  • Rattling sounds. Does it sound like a ghost is rattling its chains? Think again. There’s probably a component loose inside the AC system. 
  • Clicking. It’s okay to hear a clicking noise when the AC system turns on. However, if one hears constant clicking, this could be a problem with the thermostat. 
  • Hissing. This sound could have many causes. It may be time to replace the air filter. It could also mean there’s an air duct leak. 
  • Bubbling. That’s not a cauldron brewing. There could be an issue with the system’s drainage pipe. 

Like most AC-related problems, odd sounds from the unit do not resolve themselves. They will only worsen with time, eventually leading to the system’s breakdown. 

The Thermostat Isn’t Functioning Properly

  • Unusual or incorrect temperature readings 
  • The AC unit quickly turns on and off 
  • Energy bills are higher than usual 
  • There isn’t a digital reading––even though the batteries have power 
  • The home doesn’t remain the same temperature for long 
  • It feels humid indoors 

Most thermostats last about 10 years without having any issues. Beyond the 10-year mark, it could be time to consider a replacement. Many “smart” thermostats available on today’s market let homeowners have even more control over their house’s temperature settings. 

Uneven Cooling Throughout the Home 

With a functioning AC system, the home’s rooms should generally be the same temperature––or at least only differ by a few degrees. Uneven cooling could point to a problem with the AC system, such as: 

  • An old air filter. EnergyStar notes that one should replace their AC’s system air filter at least once every three months. Doing so lets the system “breathe.”
  • Clogged air ducts. Air ducts are passageways that transfer cool air to different parts of the home. Clogged air ducts prevent air from flowing.
  • An old AC system. The U.S. Department of Energy reports that the average AC system lasts about 10 to 20 years. Once a unit gets over the hill, it’s time to consider a replacement. Constant repairs can cost homeowners more money than just getting a new unit. 

Nobody wants to deal with a broken air conditioner. If one suspects their AC system isn’t working as expected, they should consult a trained professional.

Three Signs It’s Time To Replace The AC System

Three Signs An AC System Is Ready for a Replacement

Before replacing an air conditioning unit, it is best to first look for the signs that the system is not functioning as it should, and experts recommend asking for a second opinion. The average lifespan of an air conditioning unit is about 15-20 years.

Several signs that signify the AC unit may be ready for a replacement are abnormal sounds and smells, high energy bills, rust, and age. Sometimes, the system only needs a quick AC repair, but this is not always the case.

Abnormal sounds and smells

abnormal smellsAnytime an abnormal sound or smell comes from the system, there is cause for concern. Most of the time, homeowners should not hear anything from their AC system except the cool or warm air blowing. However, when there is a problem, it is not uncommon to hear banging, hissing, or the loud sound of the motor.

Usually, when there is a loud sound, it points to a problem with the motor, but sometimes it means the AC system is working too hard. What about smells? Most AC systems do not have a scent to them. If homeowners suddenly smell something in the air blowing from their AC vents, this is a sign that something is wrong. The smell of burning metal is a cause for concern too!

high energy bills




Outrageously High Energy Bills

An increase in the energy bill can mean many things, but it usually points to the fact it’s time to install a new AC system. When homeowners are saddled with high energy bills, it can be overwhelming and frustrating. High energy bills usually occur when the AC system takes a lot of energy and time to cool or heat a home.

Older models are not designed to use as little energy as possible, meaning that high energy bills are common. However, there are options to try when installing a new AC system. For example, looking for a high-quality and energy-efficient AC system is a great option, especially one compatible with a smart thermostat.

Other Signs To Watch Out for

There are also a few other signs that it is time to change and replace the AC system in a home other than the smell, noise, or cost. Sometimes, the outside of the AC system is rough and looks rusted. Rust can cause the system to decrease in efficiency and eventually stop working. Air conditioners with rust can be fixed, but only if caught in the early stages. Otherwise, it will need to be replaced.

Rusted or rough-looking units can be due to age and normal wear and tear. AC systems have several parts that wear down over time, so if the unit shows signs of aging, it may be time to replace it. Homeowners should immediately call an air conditioning company if they notice any of the signs above to prevent further damage.
