If you’re living in the sweltering heat with no relief in sight, there may be something wrong with your air conditioning system that you can’t detect on your own. A busted air conditioner will not only make your home unbearably hot, but it can also be dangerous to your health if left unrepaired long enough. The following 10 signs that you need emergency AC repair help you pinpoint the problem and let you know when it’s time to call the professionals to get your AC back up and running ASAP.

1. Blowing warm air

If your air conditioner isn’t blowing cold air, it could be broken. If you notice other signs of AC failure, contact a HVAC professional right away. It’s important to act quickly and fix your problem before it turns into a more serious problem, like mold or structural damage. A professional will be able to pinpoint what’s wrong with your unit and perform repairs that may include replacing a part or doing routine maintenance.

2. Strange odors

One of the signs of a problem with your air conditioner is odor. If you notice a strange, new odor coming from your unit, be sure to have it checked out. Your HVAC system works hard to keep your home free from bacteria and viruses; if it’s not working properly, these microscopic threats can quickly build up inside your system and invade your home. The easiest way to prevent such an invasion is by having regular maintenance performed on your AC.

3. Your home gets humid when you're trying to cool it down

If your home is humid when you’re running your air conditioner, it means that condensation is collecting somewhere. Check to see if a window or a door is open—and close it! - The AC/furnace isn't working right. When these appliances are malfunctioning, they can be an indoor air quality (IAQ) hazard because of increased carbon monoxide levels and risk of asphyxiation from excess carbon dioxide.

4. When your air conditioner makes strange noises

Odd sounds are often indicators of larger problems. If your system is beyond repair and requires immediate attention, call a professional before it’s too late. An expert can assess your situation quickly and accurately so that you can be back to enjoying cool indoor air when you want it most. Fixing an AC unit isn’t necessarily rocket science, but in some cases it can be complex. Don’t assume your issue will resolve itself or won’t get worse if left untreated.

5. When the vents are blowing in reverse

This can cause your system to go into what is known as a thermal bypass. This is when your unit heats up instead of cooling down. Your system has a built-in sensor that will turn it off in an emergency like this, but if left on too long or never turned back on, permanent damage can be done to your equipment.

6. When the sound from your air conditioner changes suddenly

If you’ve been around your air conditioner for years, you probably know what it sounds like when everything is in good working order. If not, ask someone who does! Odds are if there is something wrong with your system it will sound louder than usual and may even be rattling or wheezing. When in doubt, have a professional come out to take a look!

You’re most likely experiencing a small problem that can be resolved with a simple repair. More serious issues could include a blown fuse, compressor failure, or faulty wiring. Regardless of what it is, you should have an experienced technician take a look and fix it before things get worse.

7. Coolant leaks inside your home or around its outdoor unit

Losing coolant in your system is never a good sign—it means a dangerous amount of pressure and heat are building up, which can lead to extensive damage and costly repairs. These leaks usually cause dripping on nearby walls or foundations. We may also notice discoloration on ceilings or floors that indicate where air ducts and pipes run through a room. If you think your unit has developed a leak, do not wait for it to break down completely.

8. Thermostat doesn't respond correctly to temperature control settings

If your thermostat responds incorrectly, there is a good chance that it has lost communication with your air conditioner or heater. Use another thermostat to ensure that all components are working correctly. Another potential problem could be a blown fuse or tripped circuit breaker, which you can check by flipping breakers off and on until they stay turned on. If your thermostat continues to malfunction, you may need to replace it with a new one. 

To avoid potential problems, check and clean both vents and registers every six months or so. Damaged ductwork is often why thermostats stop working correctly. Additionally, make sure there is an adequate amount of airflow by using an air flow gauge on supply vents and making sure that all registers are open if you have hot air heating or cooling in any rooms of your home.

9. When your utility bills start getting higher than usual

The first sign you might need to call in an expert is when your utility bills start getting higher than usual. If they’re suddenly $100 more per month, it could be a sign that your system has been damaged and isn’t operating as efficiently as it used to. Or if you find your home cooling more slowly than normal, that can also be a sign of trouble.

When your bills start going up, don’t just assume that you’re paying more for energy. That could mean a number of things including it might be a sign that your system isn’t working as well as it used to. If you aren’t sure what to do next, contact an expert. They can help with everything from properly winterizing your unit to getting your new central air conditioning system installed and running efficiently in no time. They can even be there when you need emergency AC repair services.
