7 Signs Your AC Needs Repair

If you notice any of the following, they may be signs your AC needs repair.

1. Faulty Thermostats Are Signs Your AC Needs Repair

In the event of an ill-working thermostat, you may be experiencing a bit of deja vu. You know you’ve set it and rechecked time and time again to ensure it’s reading the right temperature. However, every time you look, the numbers seem off or they fluctuate without your input. So, what’s the problem? 

Some of the most common symptoms of a failed AC thermostat include it:

  • Running day and night, even if you’ve turned it off
  • Refusing to heat or cool despite its setting
  • Appearing to be off and not functioning, even after installing new batteries

In addition, you may notice that the temperature changes from room to room even if you’re sure you’ve set it right. All of these are serious issues you need to address right away.

2. It Blows Warm Air Only

Nearly 90 percent of American homes have air conditioning of some kind. Of this large number of homeowners, we can bet that no one likes a blast of warm air when they’re expecting a cool breeze. This is especially true during the summer months. Yet, blowing warm air even in a cool air setting is a common problem air conditioning units face. If this is a problem, you may want to call the professionals. 

3. Cool Air Flows, But There’s Still Moisture In The Air

One of the main jobs your AC unit is responsible for is removing humidity in the air while it cools. This combination is what makes your home both breezy and bearable to live in. However, air conditioners do occasionally fail to remove humidity. In this case, you’re left feeling cool but sticky and uncomfortable. That’s when you know your AC isn’t living up to its expectations, and it’s time to get help.

4. There’s A Weak Output

One of the most frustrating issues to have is an AC that blows cool air, but the airflow is weak. It’s as if you’re so close to a solution but don’t know how to get there. Unfortunately, a weak output of air could have several causes.

Here are a few reasons you may be experiencing a weak AC airflow:

  • Clogged air filter
  • Frozen evaporator coil
  • Blocked air ducts
  • Faulty AC blower

Instead of using your own time and energy, talk to the HVAC experts for help.

5. You Hear A Weird Noise

Your AC should run smoothly enough to make very little or no noise. So, if you hear something off, it’s time to get a tune-up. 

Common Noises Indicating Signs Your AC Needs Repair

These are the most common noises and potential problems our customers report.

  • Screeches Or Screams. These sounds can be just as frightening as they come across and can signify a malfunctioning fan motor. 
  • Bubbling. If there’s extra moisture due to a leak or blockage in your drainage pipe, you may hear a bubbling sound.
  • Loud Humming Or Buzzing. Humming is usually caused by a defective contactor relay switch, which causes your thermostat to fail. Any sounds of buzzing can be a problem with your fan blades, fan motor, and other parts of your AC.
  • Rattle Or Hiss. Nope, it’s not the sign of a snake in your home. Rattling can indicate that your AC is either filled with debris or that there’s a problem with your electrical contractor. Hissing is typically caused by an air duct leak in your home.
  • Ongoing Clicks. If you’re hearing constant clicking, you need to get your thermostat checked as it could be failing. 

6. Something Smells Off

Occasionally, you may get a whiff of something unpleasant coming from your air conditioning unit. This is normally caused by too much moisture or water in your unit, allowing mold and mildew to grow. 

Furthermore, a dead animal may have gotten trapped in one of your air conditioning chambers. Because bacteria and other parts of the animal can spread through your AC, it might smell spoiled. In this case, do not handle it yourself. Call the pros to take care of it.

However, if you ever smell sulfur or rotten eggs, it could be a gas leak and you need to book an appointment right away to avoid potentially fatal consequences. The same can be said for burning or fiery scents. These could be a sign of electrical problems, which need to be addressed quickly.
