HVAC Troubleshooting: Tips to Prevent Overloading Your System

The prospect of anything being frozen on sweltering days is appealing, especially when considering ice cream and other cold chilly goodies. However, your experience can rapidly turn into a horrible experience if your air conditioner freezes up as a result of a failure brought on by being overloaded. Usually, the most crucial time of the year is when an overworked, malfunctioning air conditioner breaks down. Usually, the abrupt temperature shift causes the breakdown. 

Usually, the frozen component is the result of a limitation in the airflow across the coil. This step in the process is what causes the air’s temperature to drop. The coil temperature, however, can quickly fall below the freezing threshold (32°F) if the airflow is constrained. Condensation and humidity freeze when this occurs. It is imperative that the owner turn off their air conditioning system right away if the equipment does not trip the breaker automatically. Any extended period of time that the appliance is left running might seriously harm the A/C compressor.

Potential Causes

If the coils of your air conditioner continue to freeze, it might be due to dirty air filters. Frequently, a dirty air filter will immediately impede airflow over the evaporator coils of the appliance. The evaporator coils will eventually be able to get very cold due to the decreased airflow, which will cause the condensation and humidity to freezing up. A refrigerant leak or a leak in a sealed system are other potential causes of the issue. It is crucial to have a competent, licensed HVAC technician examine the unit in order to identify whether any of these potential causes are having an impact on the air-conditioning system.

Compressor burnout is brought on by what?

Compressor burnout is primarily caused by owner neglect and poor installation, as well as maintenance problems like:

  • Unclean condenser oils
  • An unclean air filter
  • Leaks of refrigerant.
  • A refrigeration system that is either over- or under-charged.
  • Refrigeration system moisture (acid burnout).
  • Lack of airflow caused by a bad system placement (surrounded by weeds, bushes, covered by deck).
  • Near the condenser are many heat sources (dryer vent, hot water pipes).
  • No airflow due to debris (grass clippings, trash stuck to external system components).
  • Low voltage/high amperage issues might be caused by loose connections, corroded cables, or an inadequate electrical supply entering the property.
  • Failures of other components (fan motor, capacitor, reversing valve, refrigerant lines, thermal expansion valve, etc.).

How Can You Prevent Compressor Overloads from Causing Damage?

Don’t Neglect  Maintenance

We frequently forget that regular maintenance is necessary for every machine to function properly. Neglecting it causes issues that may have been avoided with regular maintenance, saving the need for major repairs later. At a minimum, you should replace your air filter every three months. Clear the area around your external system of any debris, leaving three to four feet above and 18 to 36 inches of clearance above each side.

Make wise use of your thermostat.

Set your thermostat to 78 degrees or higher in the summer to keep your system from running continuously. Keep it at 68 degrees or less during the winter. And always keep in mind to raise the thermostat when you’re not home to save energy. Think about using a smart thermostat that you can program to your schedule to regulate the temperature whether you are around or not.

Keep the registers and vents open.

Your system will have to work harder if your vents and registers are blocked by furniture or other things. To ensure that your system runs effectively, keep your vents free. Simply vacuum them with a brush attachment to clean your vents.

Hire a Reputable HVAC Professional.

Your compressor will last longer if it is installed correctly by a skilled professional and maintained regularly throughout the year. This maintenance should include checking the levels of the refrigerant, lubricating the connections, cleaning the coils, and operating the compressor in accordance with the manufacturer’s recommendations for system longevity.

Consider Additional Protection.

Your HVAC system can be protected by adding a compressor overload protector. This unique sensor, which is placed close to the condenser, keeps an eye on temperatures and momentarily turns off the compressor to keep it from overheating. This can avoid the thermal overload of the AC compressor and notify you of issues before they become expensive by turning off your system to allow the compressor to cool. Finding the cause of an overheated compressor is crucial because simply replacing parts could cause the problem to recur.

Before it’s too late, seek assistance if your system has been overheating more frequently. Get a system check from us right away.
