Businesses will more or less jokingly say that 80% of their time is taken up by 20% of their clients. Similarly, a few relatively simple causes often seem to take up the majority of an HVACR technician’s time. A good tip for beginning HVACR technicians is to become intimately familiar with these few but pervasive issues so they can be recognized and resolved quickly.

Leaking Refrigerant
Cooling units rely on liquid refrigerant to cool the air that passes through them. When the liquid drops, the unit can no longer cool the air as effectively. It can also cause the unit to overwork, creating other problems in different areas of the unit. However, refrigerant fluid is not intended to evaporate or drain out of the unit, so solutions aren’t simply to refill the fluid. If the refrigerant level is low, there is a leak in the unit and it should be repaired immediately.

Dirty Condenser Coils
Condenser coils remove hot air from within a building and transfer it outside. Because they sit on the outside of a unit, they gradually become dirty with dust and debris. Dirty condenser coils will work much less effectively, becoming less able to cool the air. While this is the most noticeable effect, dirty condenser coils will also shorten a cooling system’s lifetime as well as increase its energy consumption as it overworks and tries to compensate for the inefficiencies. An annual cleaning should prevent these problems. HVACR technicians may have to perform a deeper chemical clean for systems with a heavier build-up.

Clogged Drain Lines
Air conditioner condensate lines are needed for drainage, but they can become clogged with debris and algae over time. After a clog, the drip pan will overflow, causing water damage to the structure it supports. With regular maintenance, HVACR technicians can clear the lines before problems start. After a clog has occurred, technicians will use a similar process to vacuum out the lines. However, homeowners will also have to repair the damage to their houses.

Learn the troubleshooting skills you need as an HVACR technician to diagnose and repair air conditioning and heating units through TWS HVACR training programs in Jacksonville, FL and Houston, TX. HVACR training programs in Florida and Texas can prepare students with the skills they will be expected to know to take on entry-level positions within the HVACR industry.
