With the heat on in the Valley of the Sun, the need for staying comfortable and cool is a necessity. Your AC needs to run efficiently all spring long. For the most part, air conditioning units operate smoothly, but Sonoran Desert conditions can result in accelerated wear and tear on your HVAC system. You may be experiencing more problems depending on how many years your air conditioner has been operating. Here are some of the most common problems:
Fans and Blowers
After months of not running, AC fans and blowers may have issues firing up in spring. When there’s arcing or pitting on the motor contactors, it can be difficult for the motors to start up. Sometimes with servicing, fans and blowers can start working again, but many times these components need to be replaced at some point during the lifespan of your AC.
Condensation Drain Line
The condensation drain line may become clogged for a few reasons. There may be water around or beneath the drain pain under the evaporator. Typical causes include algae or mold in the pipes blocking the drain line.
Even though air conditioning refrigerant lines are completely sealed, over time leaks can start in the coils or fittings through very tiny holes. It can be difficult to visually spot or even hear any refrigerant leaks except for a hissing sound which may or may not be audible. The best way to detect refrigerant line leaks is during a springtime HVAC system tune-up.
Breakers or Fuses
Breakers and fuses keep the AC motor and compressor from overheating. When triggered, your AC unit will not work.
The most common cause of condenser coils leaking is when the coils are dirty due to dirt, dust, and debris. When cleaning with a water hose doesn’t resolve the issue, an HVAC technician will have to service the coils. Another cause of condenser coil leaks is traces of fluoride in household water causing the coil to become corroded over time.
Failed capacitors can occur from wear and tear, electrical power surges, or other fluctuations in power. Sometimes, a visual inspection can spot a burned-out capacitor. Other times, the capacitor appears fine, but isn’t functional. With electrical problems causing about 80 percent of AC repairs, fixing them is best left to trained professionals.
