10 Most Common Air Conditioner Problems in 2023



Common central air conditioning issues arise when doors are closed, and the home’s airflow is disturbed. According to an HVAC company providing fuel oil delivery in Woodbury, the converse is true, though, if you have a room air conditioner and are significant actions. Close your home’s windows and exterior doors to keep the room or related rooms separate from the rest of your house as feasible.

Improper installation, subpar service methods, and insufficient maintenance cause other frequent issues with current air conditioners. Poor central air conditioner installation can lead to inadequate airflow and leaking ducts. An HVAC company providing fuel oil delivery in Woodbury says the refrigerant charge frequently deviates from the manufacturer’s recommendations.

Unqualified service workers frequently miss refrigerant charging issues or even worsen them by adding refrigerant to a complete system. Manufacturers of air conditioners typically produce robust, high-quality, long-lasting goods. Start by looking over any fuses or circuit breakers if one of your air conditioners fails. Before resetting any breakers, give the appliance five minutes to cool down.

The high-pressure limit switch may have tripped on a hot summer day, causing the central air conditioner’s compressor to stop. You can reset it by pressing the button. Summertime happiness is air conditioning—as long as it is functioning correctly. However, issues with air conditioners inevitably arise from time to time. Get ready. Learn about the top 10 central air conditioner issues for 2023, along with detailed remedies.

1. Air Conditioner Running All The Time

You use your air conditioner often in the sweltering summer heat, but is it necessary to run it nonstop? To achieve and maintain the temperature set by your thermostat, central air conditioning often cycles on and off many times every hour. You can have an issue if the central air is running nonstop.

If that doesn’t work, consult an HVAC specialist. You may need to clean your system or fix a refrigerant leak. You’ll likely need a replacement air conditioner if an old or inadequate air conditioner brings on the problem. The air conditioner you purchase now will be significantly more energy-efficient than one from a few years ago, thanks to recent developments in air conditioning technology.

2. Refrigerant Air Conditioner Leak

Most likely, Freon is used to cool your older air conditioner. Sadly, the phase-out of this refrigerant, which was once widely used, has begun. In light of this, recycled Freon will be the only option in 2021, and even it will cost more and be more difficult to find.

The Freon within your central air conditioner won’t evaporate or get depleted because it is a closed system. Theoretically, it may last indefinitely unless the system experiences a leak, in which case your air conditioner will have to run harder to make up for the lost refrigerant.

3. Air Conditioner Water Leak

A company providing fuel oil delivery in Woodbury says, on occasion, you could see a pool of water beneath the external condenser of your air conditioner. This can be typical if the water leaks only when the air conditioner runs, especially on sweltering, muggy days. On the other hand, a persistent leak or a significant amount of water suggests a problem.

If your filter is damp or clogged, replace it. Check the temperature outside on warmer days; using an air conditioner in conditions below 16 degrees C may cause frozen coils and water leaks. Make an appointment for a professional tune-up if the issue continues.

4. Air Conditioner Making Loud Noises

Central air conditioners typically produce a certain level of noise. You might hear short clicks, clunks, squeals, or shudders during startup. A steady low hum and the odd gurgling are typical sounds throughout the operation. However, be wary of abrupt or loud noises that appear, such as grinding or screeching, as well as new ones. They might indicate significant AC issues.

Change your filter before doing anything else since blocked airflow causes dramatic sound effects. If strange air conditioner noises are still bothering you, attempt to locate them and identify what kind of noise they are so you can explain to them when you call an HVAC service for repair.

5. Air Conditioner Smells Bad

Because they occasionally don’t originate from the AC itself, central air smells can be very misleading. Instead, the HVAC ductwork is circulating scents from someplace in your house. Examples include the “rotten egg” smell caused by a gas leak or the smell of cigarettes left behind by someone who smoked inside.

According to a company providing fuel oil delivery in Woodbury, smoking outside is the simplest way to eliminate the smell of cigarettes. However, the majority of other air conditioner odors indicate a severe issue. Turn off the system and call for immediate HVAC repair.

6. Air Conditioner Not Cooling

When your central air is undoubtedly running—you can hear the motor—but isn’t providing you with that welcome cold reprieve from the heat, it may be very aggravating. Systematically go through each potential cause one at a time. Ensure the thermostat is set to cool, not just on, first.

Next, ensure that every window and door in your house is locked and that the vents are open but not covered by any objects like furniture or drapes. After that, if the filter is clogged with dirt, replace it. Finally, clean the exterior condenser unit of debris and, if necessary, lightly wash the fins.

7. Air Conditioner Blowing Warm Air

It is uncomfortable and inconvenient when an air conditioner blows heated air; the last thing you need right now is warm breezes blowing through your rooms.

Check to ensure your thermostat is not set to on or even heat. It must be in a fantastic setting. To ensure sufficient airflow, replace the filter. Examine your condenser’s circuit breaker next; if it has tripped, your air handler will continue to operate but will only blow warm air until the breaker has been reset.

8. Air Conditioner Freezing Up

In the summer, you want your central air conditioning to be comfortable and calm—not icy! Often, an air conditioner freezing is not a significant issue. But if you ignore it, your AC system might eventually sustain costly harm.

Change the air filter; you already know the drill! Additionally, increase the temperature by a few degrees, especially before you go to work or before you go to bed at night. Have an AC repair expert check for a broken fan, clogged drainage, or a refrigerant leak if DIY solutions are ineffective.

9. Air Conditioner Is The Wrong Size

Unfortunately, your air conditioner might not be the right size for your house. Why does this matter? A system that is too large will cycle too quickly to dehumidify your home correctly, while a system that is too small will never get your house cold enough.

What is the cause of this issue? Salespeople for air conditioners who are unable or unwilling to determine the precise size your home requires.

10. Air Conditioner Keeps Tripping Circuit Breaker

Because central air conditioners consume a lot of energy, your electrical system must be capable of handling the load. If your air conditioner frequently trips the circuit breaker, it draws a lot more amps than it is designed to handle. As a result, the breaker is tripping to safeguard your house from an electrical overcurrent fire threat.

Don’t just try to reset the breaker while ignoring the problem. Do your due diligence by replacing the filter and cleaning the outdoor condenser. However, the source of this issue is most likely a refrigerant leak or a broken part, such as a motor, compressor, capacitor, or wiring. A skilled AC specialist will be necessary for repair.

The Final Words

In a nutshell, it is essential to check on your air conditioner. As in summer and winter, you may need your air conditioner as a basic necessity for a luxurious lifestyle. You can rely on an HVAC company with a team of friendly experts for fast, accurate diagnosis and repair. Many companies offer HVAC maintenance and installation that is affordable and takes less time to fix your air conditioner’s problems.
