Troubleshoot Your Broken AC With Ease

When your air conditioner breaks down or begins malfunctioning, it’s generally pretty hard to miss. The tricky part is knowing which part of the AC is the source of your problem.

At Essig, we respond to AC repair calls every single day. These types of jobs are simply part of our regular service rotation routine and we make every effort to help our customers understand what causes the problem and how they can avoid it in the future.

AC Problems and Solutions

  1. Capacitors: Damaged or burned out capacitors will need to be replaced to restore power to your air conditioning’s components.
  2. Evaporator coils: Evaporator coils must be properly maintained or they could become responsible for blowing moldy air throughout your home or business. The moist condensation on evaporator coils may become hot beds of bacteria that may not only prevent your air conditioning unit from properly working, but may cause unwanted health problems.
  3. Fuses: A burnt, damaged, or loosened fuse means that you have a broken air conditioner. Our technicians always check fuses and replace them as necessary.
  4. Drain lines: It’s not uncommon for debris to get trapped and clog drain lines. Once clogged, drain line condensation may cause extensive water damage to your home or business.  It is imperative that drain lines be routinely checked to prevent an unwanted and expensive catastrophe.
  5. Relays: Relays act as switches that automatically shift to “on” or “off” directing various components to do as they are told.  It is common for relays to wear down over time or to become accidentally stuck. Stuck or worn out relays will need to be repaired or replaced to ensure a working air conditioner.
  6. Outdoor fan motors: The outdoor fan motor helps to cool air conditioning units and sometimes gets blocked by random outdoor debris. Whether it’s due to weather, sticks, or animals, it can cause your air conditioner to overheat.
  7. Indoor blower motors: The powerhouse of air conditioning units, blower motors function to push air through the ducts to your home or business. Blower motors may need to be replaced if the shaft is damaged, they are making inappropriate noise, or demonstrate a decrease in air pressure.

Don’t ignore a malfunctioning air conditioner—or you’ll end up paying for it in the end. Let Essig make all necessary repairs and get your AC operating at design performance once again!
