5 Common HVAC Repairs that Technicians Face

Technicians are called in for a variety of repairs—everything from a dirty filter to complicated home connection issues. The problems a technician will face with an HVAC unit are essentially endless. Although complicated issues should be studied and understood thoroughly, it is equally important to understand how to spot and repair some of the most common HVAC issues. Thus the following includes five of those common issues that a technician is likely to face on the field.


Neglected HVAC Systems


Most homeowners understand the importance of taking care of every aspect of their home, especially the HVAC system. This includes removing fallen debris and keeping it looking clean. However, HVAC technicians will also get calls where there has been zero maintenance done to the system. This is usually involving an elderly resident who may not have the bodily ability to get the job done. So, what does this job look like? Fortunately, neglected HVAC systems are still likely going to be running, just at a sluggish pace. A technician is likely going to need to remove debris from within the system, check that there are no connection issues and that the condensate drain is also rid of any clogs.


Filter Replacements


Filters can become dirty very quickly, especially if you live within a location that attracts a lot of dirt. HVAC system filters are used to capture as much of that dirt as possible, thus keeping your unit working and your family safe from the toxins that dirt carries. However, if the filter is not changed every once in a while, it can become too heavily covered in dirt for it to function properly. This means that your unit will begin to run slower and even stop working altogether as the unit continues to heat up.


HVAC Thermostat Issues


Throughout the past few years, innovations in technology have allowed an HVAC thermostat to be programmable. This allows homeowners to simply set a time when they what their unit to turn on or off as well as the temperature they want it to be on. However, one of the most common issues involving thermostats is that they are likely to malfunction every once in a while if there are not regular checkups on them. For example, the number being displayed isn’t the actual temperature you’re getting. For many homeowners, this issue isn’t caught until the difference becomes too great. Because fixing such an issue requires technical knowledge of the unit, it is likely that most technicians are going to run into this type of problem.


Lubricating Moving Parts


Responsible homeowners understand the importance of keeping their HVAC unit components running smoothly. This usually involves the lubrication of the moving parts found within the unit. However, they are not likely to want to attempt to do it themselves in fear of either hurting themselves or damaging the components. That is why it is common for a technician to come in and conduct a simple lubrication of all the moving parts of an HVAC system.


Inspections of Fuel Lines and Connections


Homeowners want to make sure that they are safe and thus will contact technicians anytime they smell even the slightest odor of gas. This occurs when there is damage to the fuel lines that connect to the furnace. As you may already know, even the slightest gas leak can be extremely dangerous for anyone around the area.


Although HVAC system technicians will be called for a large number of jobs, the ones mentioned above tend to be the most common. That is why it is incredibly important to learn how to conduct a proper observation of the unit and deal with the issue accordingly.
