HVAC systems help maintain year-round comfort in residential and commercial buildings. Like any other technology, they require maintenance and are susceptible to occasional failures that require repairs from a trained professional. Are you considering a career in the HVAC industry? Let’s take a brief look at just a few common HVAC problems you might be called upon to fix.
Common Problems in HVAC Systems
1. Dirty filters
We’ll start with a job that you don’t even need to be a qualified HVAC tech to do. Homeowners can easily replace air filters, and it should be done regularly to help the system operate at top efficiency and maintain air quality. However, the fact is that many busy homeowners neglect doing it.
2. Clogged drain lines
This job usually starts with a call from a property owner about water pooling under indoor HVAC units. The culprit is usually drain lines that have gotten clogged up with dirt and debris or even algae and mold.
3. Faulty thermostat
Obviously, an HVAC system isn’t much use if you can’t actually control the temperature. In some cases, the cause of a thermostat not working is as simple as a drained internal battery or a tripped electrical breaker. Even if the thermostat is actually faulty, replacing one is usually a less complicated job than working on the HVAC system itself.
4. Leaking refrigerant lines
Leaking refrigerant stops the system from cooling the property like it should. Fixing the leak depends on its cause and severity. If it’s happening because of a loose part, it’s possible to tighten things up and recharge the unit. More serious leaks may need to be repaired with epoxy or solder or by replacing a damaged component.
5. Broken compressor
Leaking refrigerant can lead to more serious problems if it’s not addressed. Undercharged refrigerants can lead to the compressor overheating and failing, which is a much more serious and expensive repair.
6. Blower relay failure
The blower in an HVAC system is the part that moves air through the climate-controlled space. If the blower is running constantly even when it’s not set to do so by the thermostat, it’s often because the relay which supplies power to the system and tells the blower when to turn on and off has failed.
