What Causes Your Air Conditioner to Stop Working?

There are many reasons AC units might stop working, including:

Low Refrigerant

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

Signs your AC Unit is likely too low on refrigerant:

  1. Your electric bill rapidly increases
  2. Ice appears on refrigerant lines
  3. Water leaks around the heater
  4. Your home won’t cool
  5. Your vents blow warm air
  6. The programmed temperature is never reached
  7. 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:

Dirty Condenser Coils

When dirt and dust accumulate on condenser coils, heat transfer is significantly obstructed, causing the evaporator coils to freeze. This reduced heat transfer to outside air will lead to a less effective cooling system. Since evaporator coils are often sealed and challenging to repair, we highly recommend contacting one of our expert HVAC technicians.

Fan Problems

If your evaporator coils freeze over, the blower fan will likely overheat after straining to pull air through coils encased in ice.

An AC unit’s fan motor can also malfunction. Give us a call if:

Leaking Ducts

At CMB HVAC, we utilize industry-grade equipment to fix leaky ducts. If you are experiencing uneven airflow from your heating or AC system, unusually high energy bills, or stuffy indoor conditions, give us a call. We can get into attics and crawl spaces to inspect your ductwork for holes, poor insulation, and twisted segments.

Pools of Water Forming Around AC Unit

When moisture begins pooling around an AC unit, it may be the sign of a deeper problem. Common causes for pooling water include a faulty condensation pump or a blocked drain hole. If condensation cannot exit the unit as intended, the water will overflow and leak out. This can lead to mold/mildew and clogging of the AC system.

Thermostat Problems

A defective thermostat can cause many problems. If stuck in on-mode, it will constantly send coolant through the radiator and overwork your unit. A thermostat can also fail to respond to your settings, cause an HVAC system to short-cycle on and off, display inaccurate temperature readings, or stop working altogether. If your thermostat is old, we recommend replacing it with an upgraded smart thermostat! Our A/C repair specialists can help with the installation process.

Clogged Drains

When a drain line clogs, condensation will get stuck in the waterline and drain pan, increasing your indoor humidity levels. Too much humidity contributes to muggy conditions and mold. Sitting water in and around an AC unit can also cause corrosion and rust.

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 that is pulling in hot air from the crawl space or attic.

Insufficient Airflow

When a fan’s motor dies, the fan belt loosens, or blades get clogged with debris and dirt, your blower may stop blowing air properly. Insufficient airflow will fail to cool down your home. Fortunately, we excel at investigating poor airflow and providing fast solutions!

Frequent Cycles

Another common and harmful AC malfunction is short-cycling, which occurs when an AC turns on and off inconsistently and/or prematurely.

High Humidity

As previously noted, high levels of humidity can trigger mold, mildew, and respiratory diseases. Humid conditions are also sticky and uncomfortable.

Water Leaks

Indoor AC leaks are most likely due to a clog in the condensate drain line that is obstructing water. When clogged, the condensation will stagnate and leak water as the line becomes backed up with water trying to escape. This can cause property damage, mold, mustiness, and 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 the growth of fungus and mildew.

Unusual Noises

Loud buzzing noises are a clear sign that something is not right with your air conditioner. It may be the consequence of 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 and are the most expensive utility cost in many households. If you notice sudden or unexpected increases in your monthly electric bill, it may be a sign of AC inefficiency. If you have an old AC unit, it may be wearing out. Inefficiency is also caused by dirty filters, duct leaks, defective motors, faulty capacitors, and low refrigerant. With regular proactive maintenance, CMB HVAC can assess every component to optimize your AC unit’s effectiveness.
