Why Do Air Conditioners Stop Working?

There is never a convenient time to deal with a faulty air conditioner. Luckily, most AC problems are caused by a few common culprits. Repairs often focus on the typical reasons AC units stop working, including:

Mechanical complications
Dirty air filters
Low refrigerant
A blocked condenser unit
A defective thermostat
Frozen evaporator coils

Low Refrigerant

If left unchecked, low refrigerant will eventually lead to frozen evaporator coils. This can cause many complications.

Here are a few signs your AC unit is likely too low on refrigerant:

Your electric bill rapidly increases.
Ice appears on refrigerant lines.
Water puddles from melted ice on refrigerant lines.
Your home won’t cool.
Your vents blow warm air.
The programmed temperature is never reached.
You hear hissing or bubbling noises in the AC unit.

Frozen Evaporator Coils

Another common cause of frozen evaporator coils is a lack of airflow. Over time, insufficient airflow will cause the coil’s condensation to freeze over. The presence of ice on evaporator coils can create a feedback loop where more ice forms until the coils are entirely frozen. Fortunately, it is possible to prevent these problems by taking proactive steps, such as:

Checking refrigerant levels.
Changing your air filters.
Keeping supply vents open.
Increasing fan speed.
Checking for thermostat failure.
Inspecting the condensate drain.
Making sure window units are angled correctly.

Our certified technicians take the time to answer all your HVAC questions and help customers better understand how air conditioners work. From these frequently asked questions to your unique issues, you’ll always get honest and informed recommendations from your location One Hour Heating & Air Conditioning tech!

When Should I Call an AC Repair Technician?

It’s always a good idea to call an expert technician before you get in over your head. If you’re experiencing any of these issues, you will need expert help.

Your AC is blowing warm/hot air.
Your AC is not producing air from the vents.
Your AC is abnormally noisy.
Your AC smells musty.
Your electricity bill skyrocketed.

Warm Air

If your air conditioner is blowing hot or warm air, it's likely an issue with low refrigerant or the compressor unit. It may also result from a broken or disconnected return duct pulling hot air from the crawl space or attic.

Insufficient Airflow

When a fan’s motor dies, the fan belt loosens, or the blades get clogged with debris and dirt, your blower may stop blowing air properly. Insufficient airflow will not only fail to cool your home but may also increase your monthly energy bill and reduce indoor air quality.

Frequent Cycles (Short-cycling)

Another common and harmful AC malfunction is short-cycling, which occurs when an AC turns on and off inconsistently and prematurely. Short-cycling is often a symptom of one or more underlying complications, such as:

Low refrigerant due to leaks
A leaky ventilation system
Defective thermostat readings
Clogged air filters
An oversized or undersized air conditioner

High Humidity

As previously noted, high humidity levels can trigger mold, mildew, and respiratory diseases. Humid conditions are also sticky and uncomfortable. To help your AC remove indoor humidity, we suggest having a professional:

Adjust your fan speed.
Install a thermal expansion valve (TXV).
Clean your evaporator coils.
Check your refrigerant charge.

Water Leaks

Indoor AC leaks are most likely caused by a condensate drain line clogging and obstructing the water. When blocked, condensation will stagnate and leak water as the line becomes backed up with water trying to escape. This can cause property damage, bacterial growth like mold, mustiness, and excess indoor humidity.

Bad Smell

Stale and musty conditions are often the byproduct of AC issues. A recurring cause of musty odors is sitting water, which can accumulate in AC drain pans, ducts, and drip lines, nurturing fungus growth and mildew.

Unusual Noises

Loud buzzing noises are a clear sign that something is wrong with your air conditioner. It may result from a loose part, a mechanical malfunction with the compressor, missing or broken isolation feet, or a refrigerant leak. We can promptly inspect and diagnose the issue.

Higher Energy Bill

Air conditioners use a lot of electricity. They’re often the most expensive utility cost in a household. If you notice sudden or unexpected increases in your monthly electric bill, it could indicate a worn-out AC. If you have an old AC unit, it may need repairs or maintenance. Dirty filters, duct leaks, defective motors, faulty capacitors, and low refrigerant also cause AC inefficiency. With regular proactive maintenance, One Hour Heating & Air Conditioning can assess every component to optimize your AC unit’s effectiveness.

Replace dirty/clogged air filters.
Check thermostat settings.
Check your home’s main electrical panel to ensure the circuit breaker isn’t tripped.

Your AC Repair Questions, Answered

Even experienced homeowners have HVAC questions, and One Hour Heating & Air Conditioning has answers! These are some of the most frequently asked questions about air conditioning systems our technicians hear day in and day out.

How Much Does an Air Conditioner Repair Cost?

Several factors determine how much AC repairs cost, including:

The type of repair.
Whether or not there’s a warranty.
The condition of your AC unit.
The difficulty of the repair.
The parts needed to perform the repair.
The labor involved.

After an inspection and diagnosis, we will offer a detailed and transparent price estimate. You can rest assured that we will never charge hidden fees and will not start work without your approval.

A tight budget shouldn’t prevent you from receiving needed HVAC assistance. If you pay using one of our financing options, we can offer flexible financing, credit lines, and payment plans that work for you.

Should I Repair or Replace My Air Conditioner?

EnergyStar recommends replacing any AC unit over 10 years old. After a decade, the costs of maintaining an older AC unit often outweigh the costs of replacement, especially when you account for the improved energy efficiency of modern AC units. It is also important to remember that replacement parts often become difficult to find as an air conditioner ages. This will make future repairs complicated, slow, and expensive.

How Long Do AC Units Last?

The service life of an air conditioning system depends on the regularity of maintenance protocols, the condition of the unit, manufacturer quality, and usage frequency. In most cases, you can expect your home’s air conditioning unit to last 10-20 years.
