Obviously, a HVAC – heating, ventilation and air conditioning – system is a complex piece of machinery. Yet, even though they are indeed complex machines, they don’t really need professional people to come out to fix them so long as you know how to care for them. Of course, there are some exceptions and certain problems do require professional help. Let’s take a look at the three most common reasons as to why this is necessary.
The first reason is a broken AC. This happens most frequently during the very hot months. If the unit has to work too hard, it will eventually overload. Many people try to fix this problem themselves, which is incredibly dangerous. Considering these units have compressors and condensers, this is actually incredibly dangerous. Not just that, any self-repair will, in most cases void the warranty. The second issue is that they no longer provide heat. This problem can be compared to a broken AC. Very often, this problem appears very suddenly, without any warning. And, just as with the AC, this is a problem that should never be resolved without help. In fact, if you do decided to repair it yourself, it is incredibly likely that it will end up in a worse state than before. And phoning a professional out at that point is, of course, even more expensive. The third main problem that will generally cause you to phone out a professional is external failure. HVAC systems have to expel a great deal of excess heat to the outside. If the motor is bad, it will cause the fan to fail and the system will then shut down to prevent it from overloading. This is necessary in order to prevent a system overload. Replacing an entire motor and making sure the other elements in the system haven’t been negatively affected yet is something that only a professional is able to do.
It is important to remember that these are the three most commonly experienced problems, but that there are many others too. You should also call in professional help for infestation, broken boilers or furnaces, basic service and maintenance, dirty condensers, a broken reversing valve, dirty condensers and thermostat failure. Although you will have to spend some money on a professional mechanic, you will have to spend a lot more money on one if you allow the problem to continue. Indeed, trying to fix thing yourself and making it worse will cost even more money. Only professional help will do.
