Common Issues With HVAC

December 14th, 2012   •   no comments   

Even though HVAC units are typically very reliable, there are problems that may arise from time to time. Some of these problems can be fixed easily but others may require the assistance of a technician. One of the most common problems that is seen with an HVAC unit is a blow fuse. These fuses protect the motor and compressor from overheating. If a motor goes bad, a technician will usually check the fuses first.

Another common problem with HVAC units is a worn contactor or capacitor. These may need to be replaced to get your HVAC unit working properly again.

It’s always important to change your air filters in your HVAC unit as a dirty filter can reduce air flow. Filters get clogged from air particles and dirt. You can tell if your filter needs to be changed by holding it up to the light to see if light passes through it. If it does not, your filter needs to be changed.

A simple issue that people have with their HVAC is forgetting to turn on the thermostat. The thermostat is what controls the unit so before you call a technician, make sure to check the thermostat because it may have been accidentally turned off. This is simply human error and not the fault of the HVAC unit.

Refrigerant leaks are another common problem with HVAC units. They can usually be repaired unless they are in the condenser or evaporator coils. It’s also important to make sure that your AC unit always has the right amount of refrigerant in it.

Many people often see their compressor go out in their AC unit. The compressor is located in the condenser coil. It’s important to call a technician to look at the compressor as it may need to be replaced. Sometimes, your unit may just need the condenser coil cleaned. Since it is exposed to outdoor elements, they get dirty quite often and should be cleaned once a year. You can rinse the dirt and grime off with a hose or if it is really dirty, call a technician who may need to clean the coil with a cleaner.

These are some of the more common issues that people see with their HVAC units. It’s important to properly maintain the unit to ensure that it runs smoothly and efficiently. If you start to experience problems with the unit, you can turn to the internet for instructions on fixing some of the minor problems. For bigger issues, you may need to call a technician who specializes in repairing or replacing HVAC systems.
